Three Directions and Highlights of the Development of Architectural Coatings Industry in 2011

The competition has gradually intensified, the paint industry has developed rapidly, new technologies and new products have emerged in an endless stream, and competition has become increasingly fierce. For this reason, paint companies should understand the development trend of the world's paint industry in order to seek their own sustainable development.

To waterborne development

Nowadays, the structure of paints in the world is developing toward the reduction of VOCs. Waterborne coatings are one of the development directions. The proportion of Chinese traditional solvent-based paints has gradually declined, and the development speed of water-based paints is also fast, but low-grade polyvinyl alcohol still accounts for a large proportion. Increasing the quality of waterborne coatings and developing new ones are important links in consolidating and developing waterborne coatings. The focus of research and development should be based on vinyl acetate-acrylic copolymer emulsion, styrene-acrylic copolymer emulsion and pure acrylic series based latex paint, and strive for durability, film smoothness, fullness, construction, decoration Some breakthroughs have been made in aspects such as sex; for waterborne binders of more mature epoxy emulsions and waterborne polyurethanes, high-performance waterborne coatings should continue to be studied to meet certain special requirements.

To functional development

At present, in addition to the current functional coatings with lower quality, such as fire prevention, anti-virus, pest control, insecticide, heat insulation and thermal insulation, etc., we must step up research and solve the difficulties in building decoration. problem. Compounding technology will be an effective way to improve and satisfy various functions.

First, the compounding of functions. Such as elastic function and respiratory function complex: the excellent elastic emulsion and hydrophilic functional groups surface modified micro-shell superfine particles, so that elasticity and moisture permeability coexist. Combination of elastic function and low-pollution function: The room-temperature reactive emulsion is compounded with the coating hydrophilicity technology, and by using a cross-linked molecular weight reaction latex, the elongation and the film density are improved, and the elasticity function is combined with the low-pollution property. .

Second, to strengthen the basic research on acid rain-resistant coatings to solve the problem of acid rain corrosion in buildings, and strive to achieve breakthroughs in the matching of base material compounding technology and related auxiliaries, and to solve the problem of China’s increasingly severe acid rain on buildings. Big problem.

Third, the base material's modification function is compounded, and the existing base material is modified with certain special properties and compounded with special functions. For example, the weather resistance of silicone-modified acrylic is combined with moisture-curing polyurethane moisture permeability to achieve dual special function.

To high-performance, high-grade development

As an ideal coating performance, not only to protect and beautify the substrate, but also give the substrate itself can not have the special features, use some new base material can make the coating get a very amazing performance, high value-added, advanced The effects, such as high weather resistance fluororesin coatings, have been used to achieve good results in construction. Because the fluororesin coating has excellent weatherability, durability, and chemical resistance compared to other synthetic resins. However, fluorocarbon resins are relatively expensive and are extremely limited in the use of exterior wall cladding. Japan Asahi Glass's fluororesin architectural coatings are all very good performance, but the raw material cost is about 80 yuan / kg. Focuses on the development of water-based fluorocarbon resins, especially fluoropolymer-modified copolymer emulsions based on fluoroethylene, making it a high quality base material with good performance, high quality, and acceptable price. To lay the foundation for the development of high-performance, high-grade coatings. In the research of waterborne polyurethane coatings, we should concentrate our efforts on product development. Polyurethane is one of the high-grade materials with excellent properties, making it water-based, not only meets the requirements of reducing pollution and saving energy, but also maintains the characteristics of polyurethane itself.

In addition, the silicone-modified acrylic resin coating is an important direction for the development of architectural coatings in China due to its excellent weatherability, stain resistance, and chemical resistance. Due to its non-toxicity and good safety performance, powder coatings will also be the main direction for high-end architectural coatings.
