Abstract

The invention discloses an anti-corrosion resin coating which is mainly prepared from the following raw materials in parts by weight: 20 parts of bisphenol F type epoxy resin, 10-20 parts of polyamide resin, 2-10 parts of polyurethane, 2-8 parts of zinc chromate, 1-5 parts of zinc chloride, 2-6 parts of mica powder, 1-5 parts of pigment, 2-8 parts of inorganic packing and 20-40 parts of a mixed solvent. The invention further provides a preparation method of the anti-corrosion resin coating. Compared with the prior art, the anti-corrosion resin coating disclosed by the invention is low in cost, simple in process, corrosion resistant, long in service life and high in solid content, and can effectively reduce environment pollution.

Description

technical field [0001] The invention relates to a resin coating and a preparation method thereof, in particular to an anti-corrosion resin coating and a preparation method thereof, which are widely used in marine engineering, transportation, energy industry, industrial enterprises, municipal facilities and other industries. Background technique [0002] Corrosion is a common phenomenon in nature, which poses a very serious hazard to people's daily life and production, especially for components in harsh environments, such as bridges, aircraft, vehicles, ships, steel structures, chemicals, medicine, electroplating workshops, etc. . Therefore, anticorrosion is a problem that people will solve all the time. At present, in daily practice, people mainly rely on anti-corrosion coatings to solve the problem of corrosion, that is, spray the finished anti-corrosion coatings on the components, and rely on the strong combination of coatings and component surfaces to achieve the purpose...
