Abstract

The invention relates to wear-resisting ceramic paint and a preparation method thereof, and belongs to the technical field of ceramics. The wear-resisting ceramic paint comprises the following components in parts by weight: 25-35 parts of quartz, 30-40 parts of fused corundum, 3-8 parts of mullite and 5-10 parts of aluminate cement. The preparation method of the wear-resisting ceramic paint comprises the following steps: mixing and uniformly stirring the components, melting the components for 1.5-2.0 hours at a high temperature of 1500-1550 DEG C, and drying the molten components to obtain the wear-resisting ceramic paint. Due to the addition of the quartz, the mechanical performances, the breaking strength and the compression strength of the wear-resisting ceramic paint are greatly improved to even exceed those of a metal material, so that the wear resistance of the sample is improved.

Description

technical field [0001] The invention relates to a wear-resistant ceramic coating, in particular to a wear-resistant ceramic coating whose flexural strength and compressive strength exceed metal materials and a preparation method thereof, belonging to the technical field of ceramics. Background technique [0002] Wear-resistant coatings occupy a considerable proportion in energy and economic cost consumption in industrial fields such as building materials, thermal power generation and metallurgical mines. Taking the cement industry as an example, the downtime caused by wear and tear accounts for 50% to 55% of the total downtime. Equipment wear and tear has become one of the crucial factors that determine whether a cement company can operate well. Therefore, improving the wear resistance of industry-related parts, reducing the consumption of wear-resistant materials, and extending the service life of wear-resistant materials are of great significance to improving equipment ope...
