The development direction of China's anticorrosive paint

Anticorrosive coating played a big role in various industries in China, the future development of China's heavy-duty industrial will to eight aspects.

One is the development of steel structure of waterborne anticorrosive primer and topcoat. Waterborne anticorrosive primer must be setbacks resolve bottom material corrosion and poor water resistance, some new type of emulsifier free emulsion on the water resistance of the modified its title from the root, in the future should focus on solving the construction function and the application of Title function. As a finishing coat, mainly in the assurance of protection function of conditions, improve its ornamental and durability.

The two is the development of high solid and solvent free anticorrosive paint series. Drilling, offshore platform and large anticorrosion engineering of ultra durable anticorrosive function requirement of the paint is very urgent, the market basically is a wholly owned foreign enterprise and imported products occupy. Our products are mainly in the technical level, economic strength, quality assurance system and product reputation and overall strength and foreign gap is large, it is difficult to enter the market. Therefore, we should first in technology development efforts, especially the primer development of lead-free and non chromium antirust pigment, namely, zinc phosphate and aluminum tripolyphosphate based antirust primer.

Three is the development of waterborne zinc rich primer. Inorganic zinc rich primer and waterborne inorganic zinc rich primer is one of long-term primer, but they are solvent based coatings. With the high modulus potassium silicate aqueous inorganic zinc rich primer base material is the high function anticorrosion coating practice tests, with potential for development.

Four is the development of heat exchanger with room temperature curing heat resistant anticorrosive paint. The anticorrosive coating of heat resistance, high heat conducting efficiency needs heat exchanger, epoxy amino coatings currently used to 120 degrees in the curing, and requires multiple coating, cannot be used in a large unit.

The five is the development of room temperature curing and construction paint. The key is to achieve the best balance point between the coating anticorrosion function, transfer function and construction functions three.

The six is the development of chlorinated rubber series of anti-corrosion coating substitutes. Because the chlorinated rubber is single component, construction, water resistance, oil resistance, excellent resistance to atmospheric aging, widely used in ships, industrial anti-corrosion and other fields, the domestic has the broad market. But because the production of chlorinated rubber by using CC1 as solvent, destruction of the ozone layer. Industrial developed countries have developed their substitutes, the more successful with the German company BAST MP chlorine ether resin series, chlorinated polyethylene or modified products.

The seven is the development of flake anticorrosive paint. Micaceous iron oxide (MIO) has excellent solvent resistance, resistance to atmospheric aging and blocking function, as the primer and topcoat is widely applied in Western europe. Domestic production of MIO there is a certain gap in particle size distribution and diameter to thickness ratio, density and other aspects of foreign products. In the development of glass flake coatings also exist similar problems.

Eight is the development of organic modified inorganic anti-corrosion materials. In recent years, foreign application organic latex modified concrete, to improve its strength, medium resistance, widely used in industrial flooring coating. The epoxy emulsion water (or solvent type epoxy) the fastest development, known as the polymer cement. Over the past 1O years, China also began to use in anti-corrosion engineering, but the development of work system, have not formed a series of products.
