Anticorrosive coating material and preparation method therefor

Abstract

Shells of solar water tanks are generally made of colored steel plates and are economical, practical and attractive, however, the solar water tanks are basically mounted outdoors, the shells of the water tanks are easily affected by surrounding environments, then, protective coatings of the surfaces of the colored steel plates easily fall off, thus, the colored steel plates are corroded, and then, the durability and attractiveness of the water tanks are affected. Therefore, it is the general trend to research and develop a high-effective anticorrosive coating material. The invention relates to the field of preparation of coating materials and particularly relates to an anticorrosive coating material and a preparation method therefor. The anticorrosive coating material is prepared from the raw materials, including epoxy resin, unsaturated poly-vinegar resin, a reactive diluent, aluminum tripolyphosphate, micaceous iron oxide, iron oxide red, talcum powder, glass powder, nano-alumina, nano-titania, an anti-settling agent, a film forming agent, a thickener, an antifoamer and a leveling agent. The coating material disclosed by the invention is a solvent-free coating material and is resistant to environmental pollution; nano-materials are added into the formula, so that the compactness of the coating material is improved, and the water resistance and corrosion resistance are improved; and the production process is simple, the performance is excellent, and the coating material can resist the corrosion of various acids and bases.

Description

technical field [0001] The invention relates to the field of coating production, in particular to an anti-corrosion coating and a production method thereof. Background technique [0002] In recent years, due to the energy crisis, solar water heaters have been rapidly promoted. At present, my country is the country with the largest production and use of solar water heaters in the world. The "going to the countryside" of solar water heaters in 2009 marks that solar water heaters have been recognized by the state. China's solar water heater industry has entered a new era. An important part of solar energy—the water tank is generally made of color steel plate, which is economical and beautiful, but the solar water tank is basically installed outdoors, and the water tank is easily affected by the surrounding environment, causing the protective coating on the surface of the color steel plate to fall off and be corroded, which affects The durability and aesthetics of the tank.
