Abstract

The invention belongs to the technical field of spray coatings and particularly relates to high-strength explosion-proof spray coating which has high high-temperature strength, good high-temperature wear resistance, high adhesion and large bonding property as well as a preparation method thereof. The high-strength explosion-proof spray coating comprises components in percentage by weight as follows: 65% of brown fused alumina, 5% of pure calcium aluminate 75 cement, 5% of Guangxi white clay, 5% of silicon metal, 0.9%-1.2% of aluminum metal, 0.8%-1.2% of explosion-proof fiber, 7%-9% of sepiolite powder, 10% of alpha-alumina powder and 2% of sodium tripolyphosphate. The invention aims to provide the high-strength explosion-proof spray coating which is explosion-proof at high temperature andgood in heat conducting property.

Description

technical field [0001] The invention belongs to the technical field of spray coatings, and in particular relates to an explosion-proof spray coating with high high-temperature strength, good high-temperature wear resistance, high adhesion, high cohesive force and high strength, and a preparation method thereof. Background technique [0002] Spray coating is an unshaped refractory material applied by mechanical spraying method using pneumatic tools. It consists of refractory aggregate, powder, binder (or admixture). Due to the repeated and continuous impact of cement and aggregate and other constituent materials during the spraying process, the sprayed materials are compacted, so the sprayed coating has better density and mechanical strength. The existing explosion-proof spray paint has low adhesion, low high-temperature strength, poor high-temperature wear resistance, low thermal conductivity, large waste and short service life.
