Abstract

The invention discloses an anti-ozone and ultraviolet-resistant non-toxic ceramic anticorrosive coating, which relates to the technical field of an anticorrosive coating, which aims to solve the problems that the anticorrosive coating in the prior art contains a toxic volatile organic solvent and environment is polluted due to a large VOC emission amount. The technical scheme point of the coatingis characterized by comprising a component A and a component B; the component A includes the following components in parts by weight: 45 to 55 parts of organosilicon-modified epoxy resin, 8 to 12 parts of polyglycidyl ether, 12 to 18 parts of pigments, 8 to 12 parts of a filler, 0.3 to 0.7 parts of an anti-settling agent, 0.8 to 1.2 parts of an anti-cracking agent, 1.8 to 2.2 parts of a softeningagent, and 4 to 0.6 parts of a coupling agent; and the component B is a non-toxic curing agent, and is a mixture of at least two of a fatty amine curing agent, a polyamide curing agent, and a fatty amine addition product. The anticorrosive coating has the characteristics of no organic solvent addition and zero VOC emission. The invention also provides a method for preparing the anticorrosive coating. The anticorrosive coating has the advantages of good ozone and ultraviolet resistance, and a coating layer obtained by curing has the advantages of good anti-fouling and wear resistance.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion paint and its preparation, more specifically, it relates to an anti-ozone anti-ultraviolet and non-toxic ceramic anti-corrosion 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 existing Chinese patent with authorized notification number CN103509429B discloses a kind of anti-corrosion coating with strong anti-oxidation and anti-acid and alkali corrosion performance and its preparation method. The ratio of raw materials inc...
