Abstract

The invention discloses a single-component epoxy primer. The invention is characterized in that the single-component epoxy primer is prepared from the following raw materials in parts by weight: 73-78 parts of E-12 epoxy resin, 30-35 parts of 582-2 amino resin, 2-3 parts of aluminum powder, 0.5-1.0 part of dimethyl silicone oil, 3-4 parts of nano brick slag powder, 1-2 parts of antimony trioxide, 1-2 parts of lauryldimethylamine oxide, 8-10 parts of white latex, 1-2 parts of sodium lauryl sulfate, 3-4 parts of 2-butoxy-ethanol, 1-2 parts of isopropanol, 10-12 parts of ethoxylated trimethylolpropane triacrylate, 2-3 parts of dicumyl peroxide (DCP), 1-2 parts of silane coupling agent KH550 and 3-4 parts of dispersing aid. The dispersing aid enables the paint to be dispersed uniformly and maintains the stability of the paint; the paint film is light and thin, but has excellent corrosion protection effect; the added aluminum powder has the function of cathode protection; and thus, the single-component epoxy primer saves the cost, is simple in preparation technique and is especially suitable for metal corrosion protection.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a one-component epoxy primer and a preparation method thereof. Background technique [0002] As an important coating, epoxy paint is widely used in the coating anti-corrosion process due to its good anti-corrosion performance. Can be used as primer and intermediate coat for metal products. [0003] The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the paint system play its best good effect. [0004] Metal corrosion is the result of chemical or electrochemical reactions between the surface of the metal and the medium in the surrounding environment from the surface to the inside, causing the metal to be damaged and lose its original pro...
