Abstract

The invention discloses a silicon carbide coating which is characterized by being prepared from the following components in parts by weight: 10-30 parts of silicon carbide powder, 2-5 parts of a solvent, 12-18 parts of epoxy resin, 3-5 parts of epoxy acrylate, 10-12 parts of glycidol, 8-10 parts of a titanium dioxide pigment, 8-10 parts of phenyl propyl lactate, 10-12 parts of tourmaline and 7-14 parts of an auxiliary, wherein the auxiliary is prepared from the following components in parts by weight: 10-15 parts of a dispersant, 20-35 parts of a curing agent, 5-10 parts of a thickener, 0.5-0.8 part of a wetting agent, 5-10 parts of a coalescing agent, 1-5 parts of a pH adjustor, 5-10 parts of a silane coupling agent and 2-6 parts of a flatting agent. The silicon carbide coating disclosed by the invention can resist long-term immersion of strong solvents and mixed solvents, oxidation corrosion of concentrated sulfuric acid and concentrated hydrochloric acid, corrosion of high-temperature chlorine and high-temperature seawater corrosion, and can maintain relatively good water and corrosion protection at a high temperature of 1000 DEG C and has wear resistance and self-cleaning property. The invention further provides a preparation method of the silicon carbide coating.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a silicon carbide coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] With the development of technology, the requirements for environmental protection have increased, and the research on anti-corrosion coatings has received more and more attention. Anti-corrosion coatings are required to protect the painted objects and equipment, and also require good anti-wear and self-cleaning properties. However, the existing coatings that can meet such requirements still have certain technical defects, which need further research or discussion. Contents of the invention [0003] The invention overcomes the defects in the prior art and provides a silicon carbide coating and a preparation method thereof. The prepared coating can withstand the corrosion of strong acid, the corrosion of high-temperature chlorine gas...
