Problems solved by technology

At present, the anti-rust paint on the market is mainly divided into two types: oil-based paint and water-based paint. Among them, oil-based paint has the advantages of low price and convenient use, but the surface of oil-based paint is greasy and easy to attach dirt, which is troublesome to clean, and the composition contains Toxic substances such as nitrite and chromate are harmful to the health of paint spraying operators and are rarely used at present
[0003] Water-based paint has the advantages of environmental protection, safety and health, and with the advancement of material technology, the film-forming effect, anti-corrosion, and anti-aging properties of water-based anti-rust paint have been very good, but the adhesion of water-based anti-rust paint, film stability, etc. The comprehensive performance still needs to be improved, and the production cost of water-based antirust paint is generally high

Abstract

The invention belongs to the technical field of paint materials, and particularly relates to anti-rust paint for electrical equipment. The anti-rust paint is prepared from the following components ofwater-base resin, modified water-soluble silica sol, zinc oxide, talcum powder, sericite, zinc phosphate, barium sulfate, a thickening agent, a flatting agent, pigment, a defoaming agent and deionizedwater. The water-base resin is water-base anionic acrylic resin emulsion; and the water-soluble silica sol is modified by adding nano carbon powder and iron oxide and adopting a mix heating mode. Thecomponents of the anti-rust paint need to be ground and refined after being mixed and dispersed, so that the paint material is more uniform and finer, a protection layer generated after the paint issprayed is more stable and compact, and the protection performance of the paint material is improved. The anti-rust paint has the advantages of excellent oxidation resistant and corrosion resistant properties, free of toxicity and harm, and low production cost.

Description

technical field [0001] The invention belongs to the technical field of paint materials, and in particular relates to an antirust paint for electric equipment. Background technique [0002] Anti-rust paint is a coating that can protect metal surfaces from chemical or electrochemical corrosion of the atmosphere, sea water, salt spray, etc.; the main components are anti-rust pigments and film-forming substances. At present, the anti-rust paint on the market is mainly divided into two types: oil-based paint and water-based paint. Among them, oil-based paint has the advantages of low price and convenient use, but the surface of oil-based paint is greasy and easy to attach dirt, which is troublesome to clean, and the composition contains Toxic substances such as nitrite and chromate are very harmful to the health of paint spraying operators, and are rarely used at present. [0003] Water-based paint has the advantages of environmental protection, safety and health, and with the a...
