High temperature-resistant and wear-resistant heavy-duty anticorrosive paint and preparation method thereof

Abstract

The invention relates to anticorrosive paint and a preparation method of the paint, in particular to high temperature-resistant and wear-resistant heavy-duty anticorrosive paint and a preparation method of the paint. The high temperature-resistant and wear-resistant heavy-duty anticorrosive paint comprises component A and component B, wherein the component A comprises the raw materials by mass percent: 13-31% of epoxy resin or 14-16% of phenolic epoxy resin, 0-6% of boron-containing phenolic resin, 4-7% of titanium dioxide, 5-8% of barium sulfate, 3-5% of silicon carbide, 5-8% of talcum powder, 0.3-0.5% of white carbon black, 0.9-2% of nano titanium slurry, 6-8% of liquid nitrile butadiene rubber, 0.9-2% of organobentonite, 0.02% of defoaming agent and 30-54% of mixed solvent; and the component B comprises modified amine cured substance or dicyandiamide. The preparation method comprises the steps of: dispersing for 2h by ball milling according to the proportion, and then preparing the component A; and adding the component B into the component A at the room temperature to obtain the high temperature-resistant and wear-resistant heavy-duty anticorrosive paint. The heavy-duty anticorrosive paint is good in high temperature resistance, high in mechanical resistance and ideal in effects of resisting acid, alkali and salt, and can be used for protecting metal material for a long time in the high-temperature environment with acid gas and impurities.

Description

technical field [0001] The invention relates to an anti-corrosion coating and a preparation method thereof, in particular to a high-temperature-resistant, wear-resistant, heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] In the process of oil exploitation, metal pipelines need to be in the environment of high temperature, acid gas and impurities for a long time. In this case, the corrosion of metal materials is very serious. People are looking for an efficient protective measure or anti-corrosion material to solve this problem. Generally, the epoxy anti-corrosion coatings we use have poor high temperature resistance, low mechanical strength, and unsatisfactory effects on acid, alkali, and salt resistance. It is difficult to protect metal materials for a long time in high-temperature environments containing acid gases and impurities. Contents of the invention [0003] The object of the present invention is to provide a kind of...
