Speaking of car paint, perhaps everyone's first impression will be colorful body colors, indeed these different colors to the city travel added a bit of color. But automotive paint is far from what we see so simple, from varnish, color paint, medium coating, to the original paint, repair paint, passenger car paint, commercial vehicle paint and so on, the development of the paint market is in full swing, then on this basis, what kind of trend will be presented in the future?
With the gradual maturity of China's automobile industry and the increasing number of automobiles, the intensification of the market competition in the whole vehicle sales market and the further shrinking of profit margins, the automobile maintenance industry will become the largest profit in the automotive industry chain "cheese". Car coating in the entire car maintenance process for a larger profit piece, the original coating process of automotive painting to oil-based paint construction process, oil-based paint there are a large number of VOCs (volatile organic matter), bringing about very serious environmental pollution
C.
.
with the improvement of environmental awareness of the whole society, environmental protection issues in the automotive after-car market have been paid more and more attention by consumers, practitioners and relevant regulatory authorities. 4S stores and auto repair shops are facing more and more stringent environmental assessment, and VOC is an important indicator, water-based coatings are also favored by the market.
Since the birth of the automobile, after decades of efforts by paint workers, as one of the important supporting materials of automotive coatings, such as decorative, corrosion-resistant, stone-resistant, construction and weather resistance have been greatly improved and improved, basically meet the needs of the automotive industry. But people's pursuit of perfection requirements are endless, the development and production of high-performance automotive coatings is our eternal subject. The call to protect the earth's environment and reduce air pollution is getting louder and louder, and environmental problems are also very strongly affecting the development of automobiles and related industries. Therefore, water-based, since the 20th century has been the world's paint industry to develop new products of the basic policy and development direction.
automotive paint mainly includes primer, medium coating, finish paint, which is divided into color paint and metal flash paint. The hydration process of automotive coatings is carried out step by step from bottom to surface. As early as the 1960s, Europe, the United States and other developed countries have taken the lead in the use of water-based electrophoresis primer, the current primer has more than 90% of the use of water-based paint, 88% of the car coating has also adopted water-based technology, water-based metal flash primer application of more than 65%.
Today, china's automotive industry is booming, its consumer trends and technology trends are triggering a new round of changes and leaps, followed by the automotive water paint industry will also usher in unprecedented opportunities and challenges.
Water-based paint is water as a thinner, no organic solvents of a coating, simply put, it is free of benzene, toluene, xylene, formaldehyde these toxic heavy metals, water-based paint non-toxic, non-irritating odor, is harmless to the human body, also does not pollute the environment. From the aspect of human living environment, low-pollution, pollution-free water-based paint construction has become the development trend of automobile coating, water-based paint coating process coating quality is comparable to traditional solvent-based paint, while VOC emissions are small. After spraying with water-resistant paint, the surface of the paint film is relatively plump, the color crystal clear, but also has water resistance, wear resistance, aging resistance, as well as not easy to yellow, dry quickly and other advantages.
Water-like paint technology has become the mainstream trend of automobile coating process, from environmental protection considerations, the state will be more and more attention to the environmental pollution caused by the coating process, with the continuous improvement of technology and technology, and ultimately believe that water-like painting technology will gradually replace the traditional oily paint process.
