Abstract

The invention provides a ceramic surface material, which comprises the following components: 20.0wt%-70wt% of organic silicon, 20.0wt%-70wt% of organic solvent, 1.0wt%-50wt% of filler, and 0.1wt%-3wt%of auxiliary agent, wherein the organic solvent is selected from one or more of butyl acetate, xylene, n-butyl ether, diethylene glycol monobutyl ether acetate, methylcyclohexane, n-octane and butyltitanate; the filler is composed of graphene, graphite, transition metal oxide, composite silicate, rare earth oxide and metal. The components in the ceramic surface material cooperate with each other, so that the ceramic surface material has better comprehensive performance when being used as a coating.

Description

technical field [0001] The invention relates to the technical field of surface materials, in particular to ceramic surface materials and surface coatings. Background technique [0002] In the production and operation of aviation, spacecraft, power plant boilers, biomass boilers, waste incineration boilers, petrochemical heating furnaces, small and medium industrial boilers, various engines and other thermal equipment, high-temperature corrosion, erosion wear and contamination of heating surfaces Slagging, etc., have caused great hidden dangers to the safe operation of the above-mentioned equipment, and will also affect the heat exchange efficiency and heat exchange capacity of the above-mentioned equipment. High-temperature corrosion and erosion wear cause direct damage to the heating surface. Contamination and slagging on the heat exchange surface directly lead to a decrease in heat exchange capacity, an imbalance in the thermal system of thermal equipment, and a decrease i...
