What is polymer cement waterproof mortar? Introduction of construction technology.

Cement mortar products will be familiar to everyone. This is a very common building material with a wide range of applications, but it has certain limitations. So many merchants have introduced polymer cement waterproof mortar. What is polymer cement waterproof mortar?

What is polymer cement waterproof mortar?

Waterproofing of kitchen and bathroom is very important, and waterproof materials are fundamental! But do you know anything about waterproof materials? Here is a very classic waterproof material, polymer cement waterproof mortar. How about polymer cement waterproof mortar?

The classic is mainly because it is a new generation of environmental protection products produced by advanced technology. It is a cement-based composite material made of polymer waterproof mortar, which is made by mixing polymer waterproof emulsion, special cementing material and high-quality aggregate according to a special process. As a new inorganic waterproof material with rigid-flexible combination, its curing effect is generally low, and its back surface has high water seepage resistance and can withstand temperature changes. Therefore, it has the advantages of bridging slight cracks in the structural layer and directly sticking tiles.

In addition, it has a wide range of applications, not only for kitchen and bathroom waterproofing, but also for exterior walls, balconies, roofs, windows, through-wall pipelines, floors, ports, docks, roads and bridges, pools, water towers, civil buildings and other mortar waterproofing projects. It can also be used for pasting indoor and outdoor decorative materials, especially for occasions with acid resistance, alkali resistance, salt corrosion resistance or flexibility requirements.

Compared with traditional waterproof materials, polymer cement waterproof mortar has the advantages of incombustibility, frost resistance, non-toxicity, wet construction, firm bonding with base, no shell, long service life, low cost and good aging resistance. At the same time, it is especially suitable for basement, swimming pool, bathroom, water tank, sloping roof and other parts that need waterproof treatment. It is a new type of green waterproof material that meets the requirements of environmental protection.

Types of polymer cement waterproof mortar

There are many kinds of polymer cement waterproof mortar products, and the preparation methods of polymer cement waterproof mortar are not consistent. Let's introduce some common polymer cement waterproof mortar used at ordinary times. The types of polymer cement waterproof mortar include: polymer cement, acrylate emulsion waterproof mortar, silicone waterproof mortar, cationic neoprene emulsion waterproof mortar, EVA emulsion waterproof mortar, epoxy resin waterproof mortar, etc.

Polymer cement waterproof mortar is widely used in daily life, which brings great convenience to our daily life. Mix proportion of polymer cement waterproof mortar

In the use of polymer cement waterproof mortar, the mixture ratio of polymer cement waterproof mortar is extremely important. Let's introduce the mixture ratio of polymer cement waterproof mortar for everyone. The mixing ratio of polymer cement waterproof mortar in toilet is cement: sand: perlite: waterproof liquid = 1:2.5:0.0005:0.7. The material ratio of insulation layer construction process is cement: perlite: waterproof liquid = 1: 1.8: 2. The mixing ratio of waterproof material is cement: sand: perlite: waterproof liquid = 1: 2: 0.5: 1.3. The material ratio of leveling layer construction technology is: cement: sand: perlite: waterproof liquid = 1: 2: 0.2: 1.

Construction technology and matters needing attention of polymer cement waterproof mortar

1. Adding special latex to ordinary cement mortar can improve the impermeability and cohesiveness of mortar, and improve the flexural strength and tensile strength. The early strength of mortar is lower than that of ordinary cement. Mortar prepared with special cement, modified special latex or powdered polymer modified cement has the above advantages, and its early strength is greatly improved. Some mortars can even be constructed in the next working procedure within 6 hours, and the volume stability is greatly improved, reaching 100.

2. The basic process of cement mortar plastering is to find the rules first, find the four corners of the wall, level the horizontal line, then hang the separation number straight, make standard ash cake and screed, and do it again. Find the angle of yin and yang, plaster the inner wall, the bottom layer is lower than the screed, the middle layer is flat, and the surface layer is decorated. The key point of cement mortar plastering is to prepare standard ash cake before plastering. Tightening is also an important link to ensure the quality of plastering, and it is an important control sign when plastering in a large area. Finding the square of Yin and Yang angles is also an important process directly related to the quality of subsequent decoration projects.

3, cement mortar in use, also often mixed with some additives such as micro foaming agent, waterproof powder, etc. To improve its machinability and consistency. Concrete is made by adding stones into cement mortar in proportion. The label strength of cement mortar refers to the overall distribution value of compressive strength of 7.07CMX7.07CMX7.07CM cube specimens made and maintained by standard methods at the age of 28d. 100 cement mortar means that its strength is 100Kg/cm2, all of which are changed to MPa, and 100 corresponds to M 10. The mixture ratio varies according to different raw materials and mortar uses. In building engineering, the purpose of cement mortar is to build foundations and walls, and it is used as an adhesive for building block materials, such as rubble and red bricks. The second is for indoor and outdoor plastering. When using cement mortar, some additives, such as micro foaming agent and waterproof powder, are often added to improve its workability and consistency.

4. It is suitable for waterproof and anti-leakage works in various parts of buildings such as external walls, roofs, bathrooms, pools, etc., and can also be used for waterproof and anti-leakage works in various underground works such as basements, tunnels, dams, subways, etc., especially for anti-leakage plastering or painting of porous materials such as aerated concrete and hollow bricks. Generally used cement is ordinary portland cement with strength grade not lower than C32.5, and medium sand or fine sand is used according to different construction objects. When preparing cement slurry, it is only necessary to mix cement and latex evenly with proper amount of water according to the formula ratio, and the amount of latex is about 0.1kg/m/m. When preparing waterproof mortar, dry mix cement and sand evenly according to the formula ratio, then add the specified latex and water and stir evenly by machinery or manual. The prepared waterproof mortar should be used up within 1 hour. Mortar should be smooth and solid, and surface floating dust, dust and oil stains should be removed. Leaking parts should be treated with plugging materials first, and the surrounding areas where metals of different materials contact with plastic pipes should be polished clean. Brush the cement slurry on the treated base surface to improve the adhesion with the base surface. After the cement slurry is not sticky, the mixed polymer cement mortar can be evenly scraped on the base surface, leveled and polished with a trowel. Generally, the thickness of the external wall is 3-5mm, and that of the underground cavern and pool is 5-8mm. Polymer cement mortar needs layered construction. After the initial setting of the first layer of polymer cement mortar, the second layer of polymer cement mortar can be applied until. After 24 hours of construction, wet curing is needed, and the curing time varies according to the temperature conditions, and 3-5 days at room temperature is appropriate. When pasting decorative materials, cement, clean mortar or waterproof mortar should be evenly spread on the surface of the base and the pasting surface of decorative materials respectively, and then pasted on the surface of the base, and then aligned and compacted.
