Abstract

The present invention is one kind of high molecular plastic alloy powder for hot molten anticorrosive thick lining. The high molecular plastic alloy powder consists of linear low density polyethylene, isotatic polypropylene, chlorinated polyether, ultrahigh molecular weight polyethylene, white carbon black powder and other eight kinds of material. The high molecular plastic alloy powder has reasonable composition, anticorrosion, antistatic, antiageing, antiwear, environment friendship and other advantages.

Description

1. Technical field [0001] The invention relates to an anti-corrosion lining material, in particular to a composite powder for polymer plastic alloy hot-melt thick film lining. 2. Background technology [0002] The existing anti-corrosion materials for polymer plastics are mostly solvent-based coatings, which contain a large amount of organic solvents, and solvents account for about 70% of the coating components. These organic solvents need to be All the volatilization is discharged into the atmosphere, 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% of the organic compounds are volatilized and discharged into the atmosphere, causing serious air pollution and public nuisance. Therefore, the country and governments at all levels must pay close attention to it. At the same time, large quantities of solvent-based coatings are flammable, explosive, and poisonous during storage, t...
