Abstract

The invention discloses a high-shielding-property, wear-resistant and anti-corrosive paint for hydraulic support structural members and preparation method thereof. The high-shielding-property, wear-resistant and anti-corrosive paint for hydraulic support structural members comprises a component A and a component B. The component A comprises, by weight, 20-30 parts of a resin base material, 5-15 parts of non-floating aluminum powder, 20-30 parts of ceramic powder, 0.5-2 parts of a nano material, 2.5-4.5 parts of an auxiliary, 10-20 parts of anti-rust pigment, 5-10 parts of N-methyl pyrrolidone and 10-18 parts of a solvent. The component B comprises, by weight, 70-80 parts of phenolic aldehyde amine, 1-2 parts of a coupling agent and 18-29 parts of a solvent. The high-shielding-property, wear-resistant and anti-corrosive paint for hydraulic support structural members has long-acting corrosion resistance, excellent shielding property and high wear resistance, can be used in an underground mine environment, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, to a high-shielding wear-resistant and anti-corrosion coating for hydraulic support structural parts and a preparation method thereof. Background technique [0002] The hydraulic support is a structure used to control the pressure of the coal mining face. It is an important equipment for the mechanized mining of coal mines, and it is also an important guarantee for modern coal mines to achieve high output, high efficiency, and mechanization of coal mining and transportation. Most of the underground coal mines are located in a high temperature and high humidity environment. The mine water contains various ions, which can easily cause corrosion of the hydraulic support, and the coal powder on the hydraulic support needs to be washed with water, causing the surface coating to be easily worn by coal powder. Loss of protection. The anticorrosion performance of conventional anticor...
