With the improvement of the scientific and technological level of economic development, people's demands for life have gradually increased. In recent years, cases of diseases caused by decoration have been continually erupted. For the essential materials in home decoration, innovation is also being carried out. People are not satisfied with beauty. Sexuality, more inclined to its environmental protection and functionality, to meet people's health, environmental protection, aesthetic needs. At present, in addition to fire prevention, anti-virus, insect control, insecticide, heat insulation and other existing low-quality functional coatings, and to carry out scientific research, we should also study and solve difficult and new problems in architectural decoration. .
At present, in addition to fire prevention, anti-virus, insect control, insecticide, heat insulation and other existing low-quality functional coatings, and to carry out scientific research, we should also study and solve difficult and new problems in architectural decoration. . Composite technology will be an effective way to improve and meet various functions.
First, the compounding of functions. For example, the elastic function and the respiratory function are combined: the excellent elastic emulsion is combined with the surface-modified microshell ultrafine particles by the hydrophilic functional group, so that the elastic ability and the moisture permeability coexist. The combination of elastic function and low-pollution function: the normal temperature reaction type emulsion is combined with the hydrophilic technology of the coating film, and the elongation and the film density are improved by using a reaction latex having a large cross-linking molecular weight to combine the elastic function with the low pollution property. .
Second, strengthen the basic research on acid-resistant rain coatings, solve the problem of acid rain corrosion in buildings, and strive to make breakthroughs in the matching of base composite technology and related additives to solve the corrosion of buildings in China due to the increasingly severe acid rain. Big problem.
Third, the modification function of the binder is compounded, and the existing binder is modified by a special property and combined with a special function. For example, the weatherability of silicone-modified acrylics is combined with the moisture permeability of moisture-cured polyurethanes to achieve dual special functions.
To the development of water
Nowadays, the world's coating variety structure is developing towards reducing VOC, and water-based coatings are one of the development directions. The proportion of traditional Chinese solvent-based coatings is gradually decreasing, and the development speed of water-based coatings is also very 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. Key research and development should be based on vinyl acetate-acrylic copolymer emulsion, styrene-acrylic copolymer emulsion and pure acrylic series based latex coatings, and strive for durability, film smoothness, fullness, construction, decoration Breakthroughs in terms of sex; for water-based binders of more mature epoxy emulsions and waterborne polyurethanes, we should continue to study high-performance water-based coatings to meet some special requirements.
