Compound powder for high molecular plastic alloy thermal smelting anti-corrosion thick lining

Abstract

The compound powder for thick anticorrosive film lining of hot molten polymer plastic alloy consists of polyamide, polyvinylidene fluoride, chlorinated polyether, thermoplastic saturated polyester, ethylene-vinyl acetate copolymer, ethylene-methacrylic acid copolymer, gamma-aminopropyltriethoxy silane, gamma-(2-3epoxybioxy) propyltrimethyl silane, chromium oxide green powder, white carbon black, titanium white powder and graphite powder. It has reasonable composition, no atmosphere pollution, capacity of lowering noise, and other advantages, and may be used widely for the anticorrosive isolator and guard rail in expressway, railway, bridges and city road.

Description

1. Technical field [0001] The invention relates to a material for producing an anti-corrosion thick-film lining, in particular to a composite powder for hot-melt anti-corrosion thick-film lining of polymer plastic alloy. 2. Background technology [0002] Polymer plastics are widely used in the anti-corrosion field due to their excellent corrosion resistance. However, the existing anti-corrosion materials for polymer plastics are mostly solvent-based coatings, but solvent-based coatings contain a large amount of organic solvents. Solvents account for About 70% of the coating components, these organic solvents will all be volatilized and discharged into the atmosphere during the coating and film forming process, causing (VOC) to seriously exceed the standard. The solvent-based coatings currently used in my country are as high as millions of tons, of which 70% are Organic compounds are volatilized and discharged into the atmosphere, causing serious air pollution and public nuisan...
