Abstract

The invention discloses a rust-proof coating. The coating comprises a component A and a component B in the weight ratio of 5: 1, wherein the component A comprises the following components in parts by weight: 18-22 parts of first epoxy resin, 18-24 parts of second epoxy resin, 10-15 parts of magnet powder, 2-10 parts of iron oxide red, 3-6 parts of zinc phosphate, 1-6 parts of zinc powder, 0.1-0.2 part of a dispersant, 0.2-0.3 part of an assistant and 12-15 parts of a diluent; and the component B comprises the following components in parts by weight: 56-62 parts of a first amine curing agent, 12-18 parts of a second amine curing agent and 20-30 parts of ethanol. The rust-proof coating adopts two different types of epoxy resin and curing agents to form a film by crosslinking and curing. The film-forming mechanism is that active H<+> is contained in the amine curing agents and can react with epoxy groups in epoxy resin at normal temperature and form a reticular structure by crosslinking; and the reticular structure is dense and hard, good in anti-corrosion performance, strong in adhesion and outstanding in chemical resistance.

Description

technical field

[0001] The invention relates to coatings, in particular to antirust coatings and a preparation method thereof. Background technique

[0002] In high-temperature and high-humidity areas, when the air quality is poor, the air often contains carbon dioxide, sulfur dioxide, etc., and rain can easily cause corrosion of metal parts. Therefore, anti-rust coatings are often coated on metal parts to protect metal parts from corrosion.

[0003] Generally, metal parts are protected with anti-corrosion epoxy iron red primer, which includes modified aliphatic amine epoxy curing agent, modified epoxy resin, epoxy resin, coating additives, iron red Anti-corrosion pigments, heavy-duty anti-corrosion pigments and fillers, adhesion promoters, epoxy diluents.

[0004] The above-mentioned epoxy iron red anti-corrosion primer has not very satisfactory anti-rust performance, and cannot meet the needs of customers for high anti-corrosion performance. Contents of the invention ...
