Problems solved by technology

However, due to the poor heat resistance of high-chlorinated polyethylene, the heat-resistant temperature generally does not exceed 60°C, so the heat resistance of high-chlorinated polyethylene anti-corrosion coatings is poor. Therefore, to improve the resistance of high-chlorinated polyethylene anti-corrosion coatings It is of great significance to broaden the scope of application of coatings

Abstract

The invention relates to heat-resistant high chlorinated potyethlene anti-corrosive paint and a preparation method thereof and belongs to the field of anti-corrosive paint. The paint comprises, by weight, 10-40 parts of high chlorinated polyvinyl chloride, 5-35 parts of epoxide resin, 5-25 parts of acrylic resin containing fluorine, 10-30 parts of fillers, 0.1-1 part of pigment, 0.05-0.5 part of dispersant, 0.05-0.5 part of plasticizer, 0.1-0.5 part of defoaming agent and 20-60 parts of solvent. The paint can be used at the temperature of 50-80 DEG C. The paint has the advantages of being good in heat resistance, corrosion resistance, coating and processability.

Description

technical field [0001] The invention belongs to the field of anti-corrosion paint, in particular to a heat-resistant high-chlorinated polyethylene anti-corrosion paint and a preparation method thereof. Background technique [0002] Highly chlorinated polyethylene, also known as HCPE resin, has a chlorine content of more than 60%. Because the molecular structure does not contain double bonds, a large number of chlorine atoms are randomly distributed, so it has good weather resistance, ozone resistance, heat aging resistance, Flame, chemical and oil resistance. [0003] At present, with the convening of the Copenhagen Climate Conference, the global demand for limiting greenhouse gas emissions is accelerating, and high-chlorinated polyethylene anti-corrosion coatings have gradually replaced chlorinated rubber coatings. The anti-corrosion coating with high chlorinated polyethylene as the main raw material has the following characteristics: good flame retardancy and mildew resis...
