Abstract

The invention discloses a strong acid-base resistant composite ceramic anticorrosive coating, relates to the technical field of anticorrosive coatings and preparation of the coatings, and aims at solving the problem in the prior art that the anticorrosive coating needs multiple coating to achieve the desired thickness and has poor abrasion resistance. The coating includes components A and components B. The components A include the following by weight: 45-55 parts of high temperature resistant multifunctional epoxy resin, 8-12 parts of polyglycidyl ether, 12-18 parts of ceramic powder, 8-12 parts of chemical fiber powder, 3-7 parts of pigment, 8-12 parts of filler, 0.4-0.6 part of anti-settling agent, 0.8-1.2 parts of anti-cracking agent, 1.5-2.5 parts of softening agent and 0.3-0.7 parts of coupling agent; the components B are formed by mixing aliphatic polyamine curing agent, tertiary amine curing agent and imidazole curing agent according to the ratio of 1:0.8:0.5 by mass. A preparation method of the above anticorrosive coating is disclosed correspondingly. The coating prepared by the method has the advantages of high coating thickness, high compactness, good abrasion resistanceand good acid and alkali resistance.

Description

technical field [0001] The invention relates to the technical field of anticorrosion paint and its preparation, more specifically, it relates to a strong acid and alkali resistant composite ceramic anticorrosion paint and a preparation method thereof. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. [0003] The Chinese patent with the existing application publication number CN107936716A discloses a fluorocarbon acid and alkali resistant heavy-duty anticorrosion coating, which includes component A and component B packaged separately. Component A is composed...
