Abstract

The invention discloses an aerogel hybrid microsphere grafted silicon composite coating which is prepared from the following raw materials in parts by weight: 3-5 parts of superfine silicon dioxide aerogel, 7-9 parts of ferric chloride hexahydrate, 10-12 parts of ferrous chloride tetrahydrate, 2-3 parts of citric acid, 1-2 parts of methylacryloyloxypropyl trimethoxy silane, 100-130 parts of tetraethoxysilane, 5-7 parts of hexafluorobutyl acrylate, 0.1-0.4 part of azodiisobutyronitrile, 0.1-0.2 part of sp800, 1-2 parts of chlorthal-dimethyl, 2-4 parts of hydrolyzed polymaleic anhydride, 0.6-1 part of polyacrylamide, 1-2 parts of casein, 0.3-1 part of zinc cyanurate, 0.1-0.2 part of ethyl naphthol, 3-5 parts of calcium phosphate and appropriate absolute ethyl alcohol and dimethyl formamide. In the invention, the added silicon dioxide aerogel can effectively improve the packing dispersity in resin, and the stability and impact strength of the finished product of coating are enhanced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an airgel hybrid microsphere grafted silicon composite coating and a preparation method thereof. Background technique [0002] In recent years, the use of corrosion inhibitors to inhibit the corrosion of copper and its alloys has been extensively studied. Azole compounds such as triazolimide or thiazole are considered to be efficient corrosion inhibitors for copper in different media, but their inhibitory effects depend on , in addition to the bulk properties of copper and its alloys, it is also related to the pH value of the solution, because the pH value of the solution not only affects the corrosion mechanism, corrosion products and inhibitor molecules, which is why many corrosion inhibitors inhibit corrosion in medium-acid medium One of the reasons for the ineffectiveness. Another important reason is that the inherent toxicity of azole compounds poses potential risks to the...
