With the development of science and technology, people's demands for life have been gradually raised. In recent years, there have been many cases of diseases caused by decoration, which are also innovative for the essential coatings in home decoration. People are no longer satisfied with aesthetics, but tend to be more environmentally friendly and functional to meet people's health. The demand of environmental protection and beauty.
Developing towards functionalization
At present, besides increasing efforts and scientific research on functional coatings with low quality, such as fire prevention, virus prevention, insect control, insecticide control, heat insulation and so on, we should also intensify research and solve new and difficult problems in architectural decoration. Composite technology will be an effective way to improve and meet all kinds of functions.
First, function compounding. For example, the combination of elastic function and respiratory function: the combination of excellent elastic emulsion and micro shell ultrafine particles modified by hydrophilic functional groups can make the elastic capacity and moisture permeability coexist. The combination of elastic function and low pollution function: the combination of normal temperature reactive emulsion and hydrophilic coating technology, through the use of cross-linked molecular weight large reactive latex, to increase elongation and film density, so that the combination of elastic function and low pollution.
Secondly, we should strengthen the basic research on acid rain resistant coatings, solve the problem of building corrosion by acid rain, strive to make a breakthrough in the matching of base compound technology and related additives, and solve the problem of building corrosion caused by acid rain which is becoming more and more serious in China.
Thirdly, the modification function of the base material is compounded, and some special properties of the existing base material are modified and compounded with special functions. For example, the weatherability of silicone modified acrylic acid is combined with moisture permeability of moisture cured polyurethane to achieve dual special functions.
Development towards water-based
Nowadays, the variety and structure of coatings in the world are developing in the direction of reducing voc, among which water-borne coatings are one of the development directions. The proportion of traditional solvent-based coatings in China is gradually decreasing, and the development speed of water-borne coatings is also fast, but the low-grade varieties of polyvinyl alcohol still account for a large proportion. Improving the quality of waterborne coatings and developing new varieties are important links to consolidate and develop waterborne coatings. The key research and development should be based on vinyl acetate acrylic acid copolymer emulsion, styrene acrylic copolymer emulsion and pure acrylic series emulsion paint, and strive for breakthroughs in durability, film smoothness, fullness, construction and decoration. The water-based materials of esters should continue to study waterborne coatings with high performance to meet some special requirements.
