Paint industry urgently needs "environmental protection angel"
In recent years, the problem of air pollution has attracted increasing attention from society. Especially since last winter, large-scale haze weather has occurred in many places in China, and the air pollution situation is quite severe. An important source of PM2.5, the main source of pollution caused by haze weather, is VOC. VOC emissions in the coating industry account for about 1/5 of total VOC emissions. Based on 2012 ’s 12.31 million tons of paint production in China, the paint coating was estimated that year. VOC emissions from the industry range from 4 to 5.3 million tons. (The data comes from Great Wisdom Finance.) It can be seen that the coatings industry has become one of the culprits causing smog and has a heavy responsibility. At present, China's annual output of coatings is close to 13 million tons, and the use rate of environmentally friendly coatings is less than 50%, especially the promotion of water-based coatings is extremely difficult. Compared with traditional solvent-based coatings, VOC emissions of water-based coatings can be reduced by 60% to 70%, and environmental protection benefits are obvious.
"Environmental protection angel" --- water-based paint
Water-based coatings are also the most needed coatings for environmental protection. We call them environmental protection angels and wall cosmetics. Water-based coatings refer to coatings that use water as a solvent or as a dispersion medium. They have attracted the attention of many coating manufacturers and consumers with their four major characteristics of environmental protection, safety, simplicity, and energy saving. Therefore, more and more coatings companies are paying attention to the water-based coatings market, investing a lot of manpower and financial resources in the development of water-based technologies, and striving to completely replace the oil-based coatings in the market position, so that more consumers can enjoy low-carbon green as soon as possible. Healthy life.
"Environmental protection angel" --- environmentally friendly powder coating
Powder coatings are a variety of environmentally friendly coatings that have developed rapidly in recent years. It is a 100% solid powder coating consisting of raw materials such as polymers, pigments and additives. It has the characteristics of no solvent, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of coating film. Powder coatings are completely different from ordinary coatings. They exist as fine powders. Because no solvent is used, it is called powder coating. The main features of powder coatings include: harmless, efficient, resource-saving, and environmentally friendly.
"Environmental protection angel" --- inorganic coating
Inorganic coating is a coating with inorganic materials as the main film-forming substance. It is the abbreviation of all inorganic mineral coatings, which is widely used in daily life fields such as architecture and painting. Inorganic paint is a kind of paint synthesized by applying new material formula, which has the advantage that traditional paint cannot replace. Because of the characteristics of its product ingredients, it can minimize the release of formaldehyde and other harmful substances, and at the same time it also has good moisture and mold resistance. In addition, inorganic coatings do not rely on basic materials such as petrochemicals. Its resource application, low-carbon environmental protection, etc. have good advantages. As people pay more and more attention to indoor air quality, inorganic functional coatings that can effectively decompose formaldehyde and generate negative ions are more and more favored by middle and high-end consumers, and the inorganic coatings market is gradually growing.
"Environmental protection angel" --- UV curing coating
The first patent on ultraviolet (UV) curable coatings was born in 1947. After more than half a century of development, UV curable coatings have become a more mature technology, especially as people's environmental awareness increases, production and researchers pay more attention Development and application of UV curing coatings. UV curing coating is a kind of green environmental protection coating, which fully complies with the "4E" principle. Generally, UV curing energy consumption is 1/5 of heat curing, and UV curing coating contains less volatile components and less pollution. With the increasing scope of UV curing applications, there have also been important breakthroughs in technology. The combination of UV-curable coatings and powder coatings has developed UV-curable powder coatings, combined with water-based coatings and UV-curable water-based coatings, which have long been studied. It is hot, and the technology is constantly maturing, with great development prospects.
