Abstract

The invention discloses an anticorrosion high-temperature resistant coating. The anticorrosion high-temperature resistant coating is prepared from the following components in percentage by weight: 15-18 percent of epoxy resin, 35-38 percent of petroleum resin, 12-15 percent of a resin plasticizer, 2-4 percent of a surfactant, 17-20 percent of a solvent, 3-5 percent of a multi-functional auxiliary, 0.6-0.9 percent of composite rare earth and the balance of modified acrylic resin. The invention also discloses a preparation method of the anticorrosion high-temperature resistant coating. Therefore, the anticorrosion high-temperature resistant coating has corrosion resistance and high-temperature resistance, is long in service life and does not have the problems of blistering, cracking, white specks, delamination and the like.

Description

technical field [0001] The invention relates to a coating, in particular to an anti-corrosion and high temperature resistant coating and a preparation method thereof. Background technique [0002] Corrosion is one of the main factors that cause damage to metal fixtures, especially to various vehicles such as automobiles and motorcycles, as well as other mechanical parts. The annual direct economic loss caused by metal corrosion accounts for about 2%-4% of the total output value of the national economy. At present, epoxy resins, polyurethanes, and acrylics are used as binders for anti-corrosion and high-temperature resistant coatings at home and abroad to solve the above problems, but the production process is complicated, the curing time is long, the cost is high, and the corrosion resistance time is short. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a kind of anti-corrosion and high-temperature resistant co...
