Analysis on the application of green building materials in ecological residence?

In the contemporary society where the global economy is developing rapidly, people no longer blindly pursue simple economic growth, but more consider all aspects of development from the perspective of human long-term survival, and meet one of the most basic needs of human beings, "housing", which is no exception. Since the 2th century, the blind pursuit of economic benefits brought by the industrial revolution has led to over-exploitation of resources and extreme destruction of the environment, which has directly caused a series of problems such as energy shortage, waste of resources, deterioration of the natural environment and global warming. How to make human beings develop harmoniously with nature and truly achieve "harmony between man and nature" has been a fundamental concern of human beings since ancient times.

first, the ecology of green building materials is the premise of ecological residential design

The key point of applying ecological concept in residential design is to choose green building materials to reduce the carbon emission of home decoration from the basic and source. Environmental protection, low carbon and durability are the three principles of design. All kinds of materials used in the construction of ecological residence must meet the corresponding standards of green building materials in China, and the use of green building materials is also a prerequisite for the sustainable development of ecological residence.

In the "Green Building Action Plan" promulgated by the General Office of the State Council on January 1, 213, it is proposed that: vigorously study and promote green building materials, and it is required to study and establish a series of certification systems for green building materials, and to drive and guide green consumption in the market by establishing a systematic catalogue of specific products of green building materials.

In the Key Points and Technical Guidelines for the Construction of Green Ecological Residential Quarters (Trial) issued by the Ministry of Construction, it is required that non-renewable resources should be avoided as much as possible in residential design, and more reusable building materials, recyclable materials and renewable materials (3R materials) should be used. Among them, the consumption of renewable materials is not less than 3% of the total materials used, and the reusable materials account for 4% of the total recovery rate, thus achieving the purpose of energy saving and environmental protection.

2. Application of environment-friendly building materials

1. Characteristics of environment-friendly building materials

Compared with traditional building materials, the new environment-friendly teaching materials have the following characteristics:

(1) They can meet the requirements of buildings in terms of durability, function and mechanical properties.

(2) It conforms to the cause of sustainable development, has strong vitality and meets the requirements of a harmonious environment. In other words, it is to save natural resources and energy, without pollution, radioactive substances and toxic substances, so as to reduce the burden on the ecosystem and nature and strive to realize the recycling of non-renewable resources.

(3) provide people with a safe, comfortable, warm and healthy, convenient and environmentally friendly living and working environment.

2. Classification of environment-friendly building materials

(1) Basic non-toxic and harmless materials

Basic non-toxic and harmless materials can be basically natural materials, which mainly include natural wood, stone, gypsum, talcum powder, etc. These materials are non-toxic or rarely toxic and harmful. Natural wood is the first choice for the basic non-toxic and harmless materials. Natural wood has good plasticity. Because it can combine various shapes of home furnishings only by splicing tenon and mortise structures without using adhesives containing harmful substances, it is widely used in home design, especially in the popular Nordic style rooms, which basically uses unprocessed logs. This kind of wood retains the original color and texture of wood to the maximum extent, and has a unique decorative effect.

The original wood grain and stone surface are exposed indoors, reflecting the natural style of advocating nature and rustic countryside. However, in reality, the growth cycle of trees should be considered, and deep forest logs should be mined in a planned way, and corresponding replanting should be carried out to avoid deforestation. At present, the ideal choice is to choose green and environment-friendly materials such as solid wood composite board and splicing board with less toxic and harmful adhesives.

with the development of fiber-reinforced gypsum board, ceramics, glass, pipes, composite plates, carpets, wallpaper and other composite environmental protection materials, environmental protection options are provided for the main parts of home improvement design, such as flooring, wall materials, wall decorations, pipes and plates, which not only effectively avoids the destruction of forests, but also provides diversified choices for home improvement design, realizing the flexibility and diversity of home improvement design.

other materials such as natural stone, gypsum, talcum powder, etc. are widely used as green materials in home design, as they can be used in plasterboard, paint, cable, ceramics, waterproof materials and other man-made environmental protection materials, and are also widely used in home decoration design of floors, walls and other parts.

(2) Environmental protection coatings

Environmental protection coatings are divided into environmental protection waterproof coatings and water-based coatings. In a narrow sense, green environmental protection paint refers to relatively less harmful substances, and in a broad sense, it mainly refers to outstanding functions such as non-toxicity, harmlessness, heat insulation, flame retardant, ultraviolet protection, radiation protection, insect prevention, mildew prevention, etc. Its hardness, smoothness, moisture resistance, frost resistance, air permeability, abrasion resistance, moisture resistance, corrosion resistance and strong adhesion are very obvious, its service life is more than 5 years than that of traditional paint, and it is more prominent that it is harmless to human body, especially suitable for buildings.

The green paint we refer to is only a relative concept. Environmental protection paint mainly refers to a kind of liquid or solid materials, such as wall paint and furniture paint, which are coated on the surface of objects to form a solid coating with protection, decoration or special properties. Its main matrix is vegetable oil or synthetic resin.

firstly, because of its low total volatile organic compounds (VOC), the direct harm to our environment, our society and human beings is also reduced; Second, the toxicity of the solvent used is also strictly controlled, and the probability that it can cause diseases after contact or inhalation with the human body is also reduced; Third, in the process of curing paint at room temperature, it takes a process for its solvent to volatilize. Generally speaking, after paint is dried, the solvent can basically volatilize, and only a small amount of its solvent volatilizes slowly. Under normal ventilation, its solvent toxicity can be ignored.

Because toxic substances such as formaldehyde, benzene, toluene and xylene contained in environmental protection coatings are strictly controlled, the requirements of new environmental protection standards have been met, and people's expectations of environmental protection concept in home design have been met. Environmental protection coatings have been paid more and more attention and widely used in home decoration design.

(3) Nano-materials

"Nano-materials", as a product of new technology, have certain uniqueness, and have achieved good results in the application of modern building decoration materials. Compared with traditional coatings, nano-coatings not only overcome these defects, but also have good flexibility, waterproof and other advantages, which can effectively improve dust-proof, deodorization, sterilization and heat insulation.

Another example is that traditional ceramics have the disadvantages of low hardness and easy brittle fracture, while nano-ceramics developed by nanotechnology have good plastic properties, high hardness, high heat resistance and high wear resistance, and are more and more widely used in daily life. In addition, coating the paint containing nano antibacterial powder on the surface of building materials such as sanitary ware and indoor space can play a role in sterilization and self-cleaning. If nanotechnology is adopted, Shenzhen Universiade venues can "clean themselves" and save a lot of cleaning costs.

3. Application of environment-friendly building materials in China

The application status of energy-saving and environment-friendly materials in China has been gradually valued by Chinese people for a long time. As far as Shanghai, where the domestic economy is developing rapidly, the real energy-saving and environment-friendly buildings in Shanghai are still rare in 23. Most people are used to Leng Xia fever in winter, and there are not many clear concepts about green energy-saving buildings. Nowadays, with the strong support and promotion of the government, there are more and more energy-saving and environment-friendly buildings in Shanghai, and some new projects, such as the World Expo, will reach the standard of 75% more energy-saving than ordinary buildings in Shanghai. The application of environment-friendly building materials can reflect its value in the following two aspects:

(1) Living in these buildings will make you feel more comfortable, neither cold in winter nor hot in summer. Its heat insulation and heat preservation are good, especially when the weather is extremely sultry or cold.

(2) Households can greatly save electricity bills. According to the calculation of relevant departments, under the condition of the same area and household electricity habits, energy-saving buildings can reduce electricity expenses by about 3%.

Conclusion

The essence of environmentally friendly buildings lies in the environmental protection of building materials. The reform and innovation of building materials will inevitably lead to the reform of production technology. As for the popularization and application of environment-friendly building materials, we should use high-tech and design methods and safe and environmentally-friendly production technology, so as to realize the application of environment-friendly building materials and the sustainable development of buildings. Green and environment-friendly architecture meets the needs of sustainable development of architecture, and it is also the product of harmony between man and nature. It symbolizes human civilization and is also a wise choice for human beings to maintain their own living environment. Human beings must have a sense of environmental protection and create a good and harmonious living environment. Strive to achieve the harmony between nature and people in design and practice, and create a beautiful and harmonious green home for the development of * * *.
