Two major trends in the future development of the coatings industry: water-based and functional
With the improvement of the technological level of economic development, people's requirements for life have gradually increased. In recent years, cases of diseases caused by decoration have been constantly emerging. For the essential coatings in home decoration, innovations are also being made. People are no longer satisfied with aesthetics. More inclined to its environmental protection and functionality to meet people's health, environmental protection and aesthetic needs.
Towards functionalization
At present, in addition to the current low-quality functional coatings such as fire protection, anti-virus, pest control, pest control, heat insulation, etc., we should intensify our efforts and carry out scientific research, and we should also step up research and solve difficult and new problems in building decoration problem. 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 compounded: the excellent elastic emulsion is compounded with the microshell ultrafine particles modified by the surface of the hydrophilic functional group, so that the elasticity ability and the moisture permeability coexist. Composite of elastic function and low pollution function: Compound normal temperature reaction type emulsion with coating film hydrophilic technology. By using reaction latex with large cross-linked molecular weight, increase elongation and film density, and combine elastic function with low pollution .
Second, strengthen the basic research on acid rain-resistant coatings, solve the problem of acid rain corrosion of buildings, and strive to make breakthroughs in the matching of base material composite technology and related additives, and solve the problem of China's increasingly severe acid rain corrosion of buildings Big problem.
Third, the modification function of the base material is compounded, and the existing base material is modified with some special properties and compounded with the special function. For example, the weather resistance of silicone-modified acrylic is combined with the moisture permeability of moisture-cured polyurethane to achieve the dual special function.
Development towards water
At present, the structure of the world's coatings varieties is developing in the direction of reducing VOC, and water-based coatings are one of the development directions. The proportion of traditional solvent-based coatings in China has gradually decreased, and the development rate of water-based coatings is also fast. Improving the quality of water-based coatings and developing new varieties are important links to consolidate and develop water-based coatings. Focus on research and development should be based on vinyl acetate-acrylic copolymer emulsion, styrene-acrylic copolymer emulsion and pure acrylic series latex coatings. There are some breakthroughs in terms of performance; for more mature epoxy emulsions and water-based polyurethane water-based binders, continue to study high-performance water-based coatings to meet some special requirements.
