With the increasing awareness of environmental protection and the acceleration of national environmental governance work, the environmental protection department proposed in the "13th Five-Year Plan for the Prevention and Control of Volatile Organic Pollutants" to encourage the public to actively participate in VOCs emission reduction, and encourage the public to actively choose water paint. Replacing high-VOCs-contaminated paints. Various provinces and cities across the country have successively issued a ban on oil-based coatings, and the 'oil-to-water' laws have also entered the implementation stage. Under the policy of 'oil-to-water', the era of water-based coatings has arrived.
So what is the difference between waterborne coatings and traditional oily coatings?
One, ingredients
The oily coating uses organic solvent (banana water, water of the day) as a diluent. The product contains benzene, toluene, xylene and its derivatives. In addition, the polyester coating also uses a curing agent (including TDI), so the polyester coating The toxicity is very large, and the toxicity of nitro paint is second. At the same time, oily paint contains benzene, xylene, acetone, solvent gasoline, and water is highly flammable, and the risk factor is improved. During the construction process, volatile gases are generated, which directly stimulate the sensory organs of the human body.
Water-based paint is water-based dilution solvent, ultra-low VOC content (below the national mandatory standard of 200mg / L), is a truly non-toxic and tasteless high-tech environmentally friendly products. At the same time, water is safe and non-flammable after replacing organic solvents. The characteristics, and, in the process of painting, will not produce any irritating odor, the product safety is greatly improved, and it has the characteristics of green environmental protection.
Second, smell
Water-based paints contain no special odor, non-toxic and tasteless; will not volatilize into the air, more lasting as new; no special storage requirements, easy to place and construction.
Oily paints contain strong irritating odors, which are unbearable. Gases contain a lot of harmful substances and cause harm to human health. Generally, from January to February, strong irritating odors volatilize to basically odorless, but a large number of harmful gases will be released slowly. Volatile for 10-15 years. And oily paint is flammable and must be stored separately according to fire protection requirements.
Third, the price
Water-based paints have higher technical requirements on drying time, hardness, fullness, etc., and the manufacturing process is relatively complicated, and large-scale production equipment is required to produce products with relatively stable performance, and the production cost is relatively high. This is also the same grade. The price of waterborne coatings is much higher than that of oily coatings.
Fourth, construction performance
Oily coatings should be added with Tana water or related curing agents, and must be in accordance with a fixed ratio. Therefore, in the construction process, oily coatings require professional guidance to ensure a good coating effect.
Water-based paint is easy to use directly for construction, and the construction is simple; the used materials can be stored in a cool place to continue to save.
Not all water-based paints are environmentally friendly. At present, the manufacturers of water-based paints on the market are mixed. There are many products with the name of water-based paint. In fact, it is very likely to be a product of 'fake' water-based paints. Experts in the industry pointed out that fake water-based paints on the market, In terms of VOC emissions, it is also lower than the national mandatory standard of 200mg/L. However, due to some 'fake' water-based paints, chemicals should be added when used, such as hardeners, film enhancers, special dilution water, etc. It can also be diluted with water, but because of its high solvent content, it is harmful to the human body, and some even exceed the toxicity of oil paint. Therefore, consumers should pay attention when purchasing water-based paint.
Chuandi water-based paint actively responds to the policy call of the national oil reform and environmental protection department. Since the launch of the research and development of 'Chuandi' water-based paint in 2008, the company has always adhered to the original intention of 'rejecting VOC, fighting for human respiratory health and environmental optimization'. Providing safe and healthy living environment for people. After the 'China Product Quality and Technical Supervision Center' and the 'National Quality Brand Strategy Promotion Association' jointly conducted the review and authoritative information comparison, 'Chuandi' water-based paint series products are resource-saving, Low-carbon development, independent innovation, remarkable achievements in green environmental protection and energy conservation, won China's green (non-toxic) environmental protection and energy-saving famous products, subverting the old era of toxic and harmful oily coating, creating a water-saving environmental protection that is energy-saving, emission-reducing, and beneficial to human health. New era of paint.
