High molecular plastic alloy powder for hot molten thick lining

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...

Problems solved by technology

[0006] In view of the above situation and the actual needs of anti-corrosion, the purpose of the present invention is to provide a new composite powder for hot-melt thick film lining of polymer plastic alloy, which can be effectively used for anti-corrosion lining, so as to overcome the fact that the existing anti-corrosion materials can only be used as thin films And pollute the environment, poor anti-corrosion performance, short service life, the technical solution is that the composite powder is made of linear low density polyethylene, isotactic polypropylene (IPP), chlorinated polyether (Pentone), ultra-high Molecular weight polyethylene, ethylene-vinyl acetate copolymer (EVA), ethylene-methacrylic acid copolymer (EMAA), r-aminopropyltriethoxysilane (KH550), r-(2.3 epoxy dioxy) Propyltrimethoxysilane (KH560), white carbon black powder, chromium oxide green powder, titanium dioxide, graphite powder and antioxidant CA, the composition of the invention is scientific and reasonable, easy to produce, no environmental pollution, high utilization rate, Stable performance, easy production for anti-corrosion thick film lining, long service life, good anti-corrosion effect, not only anti-corrosion function, but also anti-static, anti-aging, wear-resistant and other functions; it can resist strong medium corrosion and strong solvent, And it can be applied at low temperature or high temperature. It has the characteristics of high efficiency, saving, environmental protection, energy saving, high quality and innovation. It is a new breakthrough in anti-corrosion lining materials. Its development and application have huge economic and social benefits
