Abstract

The invention relates to a locomotive salt-fog-resistant anti-rust paint and a preparation method thereof. The paint comprises the following components in percentage by weight: 20-30% of epoxy resin, 20-25% of composite anti-rust pigment, 5-10% of talcum powder, 5-10% of barium sulfate, 5-7% of mica powder, 0.5-1% of dispersing agent, 0.5-1% of rust inhibitor, 1-1.5% of salt-fog-resistant assistant and 15-25% of epoxy resin diluter. Under the actions of the composite anti-rust pigment, talcum powder, salt-fog-resistant assistant and the like, the salt-fog resistance of the locomotive salt-fog-resistant anti-rust paint reaches 1500 hours, and the adhesive force reaches Grade 0.

Description

technical field [0001] The invention relates to a locomotive paint, in particular to a locomotive salt spray anti-rust paint and a preparation method thereof. Background technique [0002] Locomotive coatings are mainly used on rail transit vehicles such as trains, bullet trains, high-speed trains, and electric locomotives, mainly for anti-corrosion protection and appearance decoration of vehicles. The existing products are two-component coatings, and two-component epoxy primers are mainly It is improved in terms of salt spray resistance. Epoxy resin is used as the base material, and anti-rust pigments, additives, and solvents are added. According to the testing method proposed by the National Railway Corporation, the product requires salt spray resistance of more than 500h. The existing The salt spray resistance of locomotive coatings is generally 500h without blistering and rust on the board surface, and the rust width at the scratches is ≤2mm. The performance is average a...
