Problems solved by technology

[0003] Among the existing epoxy coatings, epoxy anti-corrosion coatings are mainly used for anti-corrosion on the surface of materials. Since the anti-corrosion properties of various epoxy anti-corrosion coatings vary greatly, there are concerns in the selection, and the existing epoxy anti-corrosion coatings have excellent anti-corrosion properties. Therefore, how to configure an epoxy anti-corrosion coating with excellent anti-corrosion and mechanical properties and low cost is worth studying

Abstract

The invention discloses an epoxy anticorrosive coating. The coating comprises the following components in percentage by mass: 55-65% of resin, 23-28% of pigments and packing and 12-17% of auxiliary agents, wherein the resin comprises the following components in percentage by mass: 40-50% of oil modified epoxy resin, 5-10% of oil soluble phenolic resin and 5-10% of hexamethoxymethylmelamine resin. The epoxy anticorrosive coating disclosed by the invention can form a 200-400 [mu]m-thick coating by primary coating, has excellent water resistance, saline water resistance, oil resistance and chemical resistance, has a stiff coating film, has excellent physical properties such as adhesive force, wear resistance, impact resistance and the like, and is suitable for using as a long anticorrosive coating for chemical equipment, an inner wall of a high press water pipe and a steel member exposed to a corrosive environment.

Description

technical field [0001] The invention relates to the field of coatings for metal coating, in particular to an epoxy anticorrosion coating. Background technique [0002] Epoxy coatings are generally divided into two types: oil-based epoxy coatings and water-based epoxy coatings. According to the performance, there are generally wear-resistant epoxy coatings and epoxy anti-corrosion coatings. Strict divisions should also include anti-static epoxy coatings and architectural environmental protection coatings. Oxygen decorative coatings should be subdivided into 4 categories to be more accurate. According to the analysis of the feasibility report of the China Project Feasibility Research Center, as far as the epoxy (resin floor) coating industry is concerned, there are mainly two levels of customer value. First of all, the value of product performance is the environmental performance and wear resistance of the product. After the basic performance of the product, such as wear resi...
