Abstract

The invention discloses a silicon-based hydrophobic and bacteriostatic powder coating for an electric power switch cabinet. The silicon-based hydrophobic and bacteriostatic powder coating is prepared from raw materials in parts by weight as follows: 0.7-1 part of zinc pyrithione, 0.08-0.2 parts of lanthanum oxide, 2-4 parts of sodium 3-hydroxybenzoate, 5-7 parts of 8-hydroxyquinoline, 10-14 parts of polyethylene glycol octylphenol ether, 36-40 parts of tetrabutyl titanate, 20-25 parts of cyclohexanol, 100-120 parts of unsaturated polyester resin, 2-3 parts of sodium carboxymethyl cellulose, 0.4-1 part of diisopropylethanolamine, 4-5 parts of lauryl mercaptan, 3-4 parts of maleated rosin, 0.6-1 part of butylmercaptooxo-stannane, 3-4 parts of triethanolamine borate, 0.3-1 part of 2-mercaptobenzimidazole and 14-20 parts of tetraethyl orthosilicate. Tetraethyl orthosilicate is taken as a precursor, and by the aid of added silica sol, not only are strength and hydrophobicity of the powder coating effectively improved, but also compatibility of the components is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a silicon-based hydrophobic antibacterial powder coating for electric switch cabinets and a preparation method thereof. Background technique

[0002] With the development of society, the demand for antibacterial materials will constitute a huge market, and the production of antibacterial agents and their products will become an important emerging industry field. Organic antibacterial agents have obvious short-term bactericidal effect, poor temperature resistance, and short service life; inorganic antibacterial agents have long service life, high temperature resistance, and side effects. The composite antibacterial agent rationally utilizes the advantages of the two, greatly improves the performance and scope of application of the antibacterial agent, and overcomes the limitation of the antibacterial spectrum of a single antibacterial agent. Composite antibacterial materials wil...
