"Green paint" refers to energy-saving, low-polluting water-based coatings, photo-cured coatings (uv coatings), powder coatings and so on. Until the 1970s, almost all coatings were solvent-based.
the 1970s, due to the high price of solvents and increasingly stringent requirements to reduce VOC emissions, more and more low organic solvent content and organic solvent-free coatings have been greatly
.
At present, China's wood furniture wood coating is still mainly solvent-based coatings, these high VOC coatings in the coating process will release a large number of organic solvents, organic solvents not only cause pollution to the atmosphere, but also to the health of the people caused no small harm.
government has identified powder coatings and water-based coatings as environmentally friendly coating varieties for future priority development. The development of "green paint" is the general trend of the paint industry all over the world, it is imperative.
green coating is excellent
. No.1 Excellent performance
Most of the green coatings have solvent-based pigment characteristics, its coating film bright and plump, strong adhesion, impact resistance, flexibility, water resistance, excellent decorative effect.
No.2
organic volatiles pose a direct hazard to our environment, our society and humanity itself. Paint is the second largest source of pollution in modern society. The first source of pollution is brought by the transportation industry, such as automobile exhaust, oil penetration and so on. Therefore, the pollution of the environment by coatings has been paid more and more attention.
green paint has non-toxic harmless, odorless, does not contain benzene, heavy metals, formaldehyde and other harmful substances, VOC emission value is far below the standard limit value, all indicators are in line with national standards.
No.3 is safe and
toxic solvents pose a direct hazard to production and construction personnel. Benzene and methanol, as they are known, are toxic solvents. Green paint is an inorgeable coating, inorgeable coating substation is often taken directly from nature, the production and use of the base material in the process of environmental pollution is small, most of the products are water as a dispersed medium, no adverse environmental and health effects.
are the popular categories of green paint?
No.1 water-based coatings
water-based coatings use water as a solvent, so that film-forming substances are evenly dispersed in water, also known as water-based coatings or latex coatings. Coating technology is easy to master, simple production process, easy construction, formula plasticity high advantages, but the disadvantage is that its coating film wear resistance and chemical resistance is poor, soft hardness, poor plumpness. Because water-based coatings are non-toxic, non-irritating, non-combustible and so on, it is the main development direction of "environmentally friendly coatings".
Water-based coatings after the early integration, the industry level has been rid of the past uneven, vicious competition situation, is gradually forming economies of scale, this phenomenon will promote the water-based wood coating raw materials cost pressure continued to ease, prices will gradually move towards "civilianization."
For the water-based paint has always existed pain point - soft, sticky, difficult to construct the problem, the research and development staff of the famous Starang Shield paint introduced a two-part water-based paint, greatly improved the hardness of the paint film, can be applied to wooden doors, display cabinets and other hardness of the paint film and anti-friction requirements of higher products, so that the product in hardness and operation can almost be comparable with PU paint.
No.2 UV paint
. UV paint is also known as ultraviolet light curing paint, through the energy of ultraviolet light to trigger the polymerization of molecules in UV coating cross-linking reaction, so that the paint film in 3 to 5 seconds quickly cured into a film coating process technology called UV coating.
Because of the use of photo-cured film, so UV coatings do not exist traditional paint VOC emissions, coating time is long and other issues, in line with China's vigorously promoted low-carbon economy and green economic policy, is the coating industry is actively encouraging and promoting environmentally friendly, resource-saving paint varieties.
Star UV wood paint after many years of innovative research and development, technology has been quite mature, in addition to the general UV paint high solid content, fast curing, environment-friendly, low cost characteristics, but also many high-quality characteristics, such as UV white primer whiteness, cover rate, adsorption force, wear and other indicators are more excellent;
No.3 Powder Coatings
Powder Coatings are solid powder coatings that are present in a fine powder form, transferred to the coat in powder form, and then baked, melted, cured and thus filmed. Different from ordinary solvent-based coatings and water-based coatings, its dispersion medium is not solvents and water, but air, therefore, powder coating volatile organic compounds are zero, greatly reducing the safety hazards caused by solvents.
powder coating can be sprayed automatically, almost 100 percent uity, reduce the treatment of waste in the coating industry, save energy while reducing the degree of environmental pollution to a minimum.
the conclusion
green paint to completely replace solvent-based coatings, it will take a long time. After all, China's green paint in terms of price, performance and solvent-based coatings there is still a certain gap, coupled with China's relevant environmental laws are not sound enough, paint manufacturers mostly hold a wait-and-see attitude and consumer concept is difficult to change and many other factors hinder the development of green paint.
with the development of society, the progress of science and technology and the enhancement of human environmental awareness, water-based coatings and other green coatings will gradually replace the traditional solvent-based coatings, widely used in the furniture industry.
