Confused about shopping? Let me tell you the difference between paint and paint

during the paint construction, the paint master temporarily asked you to buy a bucket of paint of XXX brand. When you saw this product, you suddenly became confused and thought that the master told me to buy paint. Why did it say paint? Are paint and paint the same thing? If not, what is the difference between paint and paint?

Evolution of the concept of paint and coating

Paint has a long history in China. The reason why it is called paint stems from the fact that this material can not be separated from vegetable oil and lacquer in the early days, so the word "paint" carries a heavy history and ancient culture. With the continuous development of science and technology, the paint industry is growing, and the varieties and categories of paints are constantly being innovated.

the word "paint" appeared in the 195s. It has always been thought in the industry that paint and paint are just two different names for the same material. In 195s-196s, even in 197s, the industry understood "paint" as a scientific name and "paint" as a common name. Therefore, at that time, the title of "paint" was somewhat academic, and it seemed that only research institutions could enjoy the title of "paint", such as paint research institute or paint laboratory. At the same time, all production enterprises are called paint factories, paint factories or paint factories.

The confusion of paint and paint names began after 198s. With the rapid development of economic construction and the rapid rise of the construction industry, the paint industry is no longer a monopoly situation in the past. A large number of similar manufacturers of domestic building systems generally use "paint" as the enterprise name. With a large number of architectural coatings products flowing into the market, the word "coating" not only came out from the sacred academic hall, but also because architectural coatings are mainly water-based products, the concept of coatings has been misinterpreted by society, and coatings and paints are mistakenly thought to be two different materials and belong to two different industries.

national standard notes on paints and varnishes

national standard (GB526.1) In the basic terms of vocabulary standards for paints and varnishes, paints are defined as a kind of liquid or solid materials that can form a solid coating film with protective, decorative or special properties (such as insulation, anticorrosion, marking, etc.) on the surface of an object. In the early days, vegetable oil was the main raw material, so it was called paint. Now synthetic resin has mostly or completely replaced vegetable oil, so it is called coating.

There are two views on the above definition:

1. At present, the reason why this kind of material is called paint is not called paint is more due to the development of paint varieties and categories, because the name of paint can not cover all kinds of products in the industry, and the word paint can cover all kinds of products in the industry, so it is more accurate and scientific to use the name of paint. For example, powder coating products should not use the title of paint, and paint and paint are not interchangeable here. Therefore, paint can cover solid powder paint and liquid paint, but it can't be replaced, so the explanation in the standard is not very in place.

2. There is something wrong with the "note" in coating terminology in the standard, that is, the word "lacquer" can be used in the name of specific coating varieties, such as ready mixed paint, thick lacquer, etc. Because in fact, the word "paint" is not only used in specific paint varieties, but also widely used in paint categories, such as acrylic paints and polyurethane paints, and also widely used in general terms in application fields, such as duty paint, automobile paints and marine paints. In fact, except for a few cases, the words paint and lacquer are universal, and they can only be expressed in specific varieties.

The concept of paint should be revised

The apparent characteristics of paint and paint are liquid, and it cannot cover solid paint except liquid paint. Since the scope of coverage is different, it is difficult to explain the concepts of paint and paint equally.

at present, water-based coatings and powder coatings have become a climate, especially architectural coatings mainly based on water-based paints have accounted for about 38% of the total coatings in China. Because the chemical characteristics of water-based paint and oily paint are essentially different, and the product properties of water-based paint and oily paint are also very different, it is unscientific to define water-based paint as a big branch of paint industry. Water-based paint and oil-based paint should be listed as two different series in liquid coatings.

Therefore, in the basic terminology standards, not only the terminology standards of paints need to be appropriately revised, but also the terminology standards of paints, paints and water-based paints. They can be defined as:

coating: a kind of liquid or solid material coated on the surface of an object to form a solid coating film with protection, decoration or special properties (such as insulation, anticorrosion, signs, etc.). Include oil paint, water-based paints and powder paint.

paint: flowable liquid paint. Including oil paint and water paint.

paint: oily paint with organic solvent as medium or high solid and solvent-free.

water-based paint: paint that can be dissolved or dispersed with water.

Xiao Bian said; The difference between paint and paint is actually a cliche. Paint and coating industry has its own clear understanding, which basically equates paint and coating, which is why there is only the explanation of the word paint in national standards. However, due to inaccurate information dissemination, the outside world will always be "confused" about paints and coatings.
