Abstract

The invention discloses an epoxy resin anticorrosive paint based on black talc and a preparation method of the paint, and the anticorrosive paint comprises the following raw materials by weight: 25-55 wt% of epoxy resin, 20-40 wt% of a solvent, 8-20 wt% of a filler, 8-15 wt% of zinc powder with fineness of 800-1250 meshes, 1-6 wt% of high temperature carbonized black talc with fineness of 1-2 [mu]m, 3-6 wt% of a pigment, 0.2-2 wt% of a dispersant, 0.2-2 wt% of an antifoaming agent, and 0.2-2 wt% of a leveling agent. The preparation process of the anticorrosive paint is simple and easy to operate; and the product is good in wear resistance, salt water resistance, acid resistance, alkali resistance and other corrosion resistance, and the surface of the coating does not blister or fall off.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an epoxy resin anticorrosion coating based on black talc and a preparation method thereof. Background technique [0002] With the development of the economy, the economic loss caused by corrosion is huge every year all over the world, and the anti-corrosion industry has penetrated into various fields. Among various anti-corrosion technologies, coating anti-corrosion coatings is the most widely used, and also the most economical, practical and effective method. Anti-corrosion coatings are widely used in modern industry, transportation, energy, marine engineering and other departments. However, at present, the anti-corrosion coatings used in China cannot meet the different requirements for anti-corrosion performance in various fields in terms of variety, quality and performance, so there is an urgent need for continuous innovation in the field of anti-corrosion coatings. [0003] Epoxy re...
