The development trend of architectural coatings

over the years, architectural coatings have developed rapidly. Coupled with the application of high technology, new varieties have been developed continuously. In terms of technology, it has also broken the traditional process based on plastering in the past, and there have been composite processes based on spraying, roller coating, brush coating, plastering and various practices. From the development of the whole coating, it shows the following characteristics

waterborne coatings in the future

due to the great harm of solvent based coatings to the environment and human health, countries all over the world attach great importance to the development of waterborne architectural coatings, and formulate relevant regulations to strictly limit the content of VOC (organic volatile substances) in architectural coatings. The proportion of solvent based architectural coatings is becoming smaller and smaller, replaced by waterborne architectural coatings. Due to the advantages of advanced technology, simple process, low energy consumption, low emission, safety and non-toxic, water-based architectural coatings has become the inevitable direction of the development of architectural coatings in the future, and has a very broad development prospect

the rise of powder coatings

due to the enhancement of people's environmental awareness, powder coatings have also attracted more and more attention. Because the powder coating does not use solvents at all, it is a new kind of building coating that saves resources and is non-toxic and pollution-free. Until the carbon fiber preform needs to be injected with resin, Europe and the United States and other countries began to develop production in the 1960s, and has always been in a leading position and may cause serious consequences. The output has accounted for 20% of the organic coating, and has continued to grow. In addition, solid coatings have also received attention. In addition to being beneficial to environmental protection and energy saving, this kind of coating is also relatively easy to be converted from ordinary solvent based coating devices. However, because the production cost of solid coatings is relatively high and the film is easy to settle, these problems must be solved in order to achieve rapid development

functional coatings are valued

with the emergence of a large number of buildings, especially high-rise buildings, functional architectural coatings have attracted more and more attention of the whole society. In manufacturing industry and research, it is very important to test and control the friction and wear performance of moving parts It is very important for quality control to be able to obtain the data of 1-stream post forging treatment equipment, such as heating furnace, heat treatment furnace, chemical etching and washing, in different environments such as humidity, temperature and lubrication. In particular, the exterior wall coating should have other special functions, such as waterproof and anti-seepage function, high pollution resistance function, anti carbonization, mold release, sterilization, antistatic, thermal insulation Fire retardant, sound insulation and other functions

synthetic resin coatings will play a leading role

with the development of chemical industry, synthetic resin coatings will be more and more widely used, and oily coatings are now facing the desperate situation of being eliminated. In synthetic coatings, the proportion of alkyd coatings and amino alkyd coatings is gradually shrinking, while propylene coatings, epoxy resin coatings, polyurethane coatings and various water-soluble resin coatings with high quality are increasing

China's building coating market is broad, and it may become the largest building coating market in the world in the future. In the future, the building coatings with the fastest growth in China's market will be polyurethane resin coatings, epoxy resin coatings, polyester and acrylic resin coatings, and the proportion of low pollution environmental adaptive coatings will be greatly increased.
