High-temperature (800 DEG C) wear-resistant paint and preparation method thereof

Abstract

The invention discloses high-temperature (800 DEG C) wear-resistant paint and a preparation method thereof. The high-temperature wear-resistant paint comprises a component 1 and a component 2, wherein the component 1 is prepared by mixing a component A and a component B; the component A in the component 1 comprises the following components: black silicon carbide, fine-grain aluminum oxide, dispersing agent, zinc oxide, modified epoxy resin, flatting agent and an auxiliary material; the component B in the component 1 comprises the following components: organic silicon modified epoxy resin, a filler, antimony trioxide, film-forming assistant and thickener; and the component 2 is curing agent and coupling agent. The high-temperature (800 DEG C) wear-resistant paint is prepared by the following steps: mixing the component A and the component B in the component 1, and curing the component 1 with the component 2. The high-temperature wear-resistant paint is prepared by compounding the double components, has excellent high temperature resistance and wear resistance, and also has the fine properties of favorable hardness, high heat stability, ductility, workability and the like. The invention also designs the method for preparing the high-temperature wear-resistant paint. The preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a coating resistant to the environmental effect of being easy to wear below 800 degrees and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] Wear is known as one of the three major forms of material failure. According to statistics, about 70-80% of equipment damage and nearly 50% of energy consumption are attributed to various forms of wear and tear every year, which not only causes waste of energy and materials, but also causes huge economic losses, serious even It also endangers personal safety and affects national development. [0003] In the energy and economic cost consumption of industrial fields such as building materials, thermal power generation and metallurgical mines, the cost due to wear and tear occupies a considerable proportion. Taking the cement industry as an example, the construction site is ...

Problems solved by technology

[0005] So far, there have been many reports on the research on wear-resistant coatings, for example: the patent of CN1339619A discloses a composition ratio of Co:WC=15-25% : 85-75% cobalt / tungsten carbide powder wear-resistant composite coating, prepared by plasma spraying method, this coating can improve the wear resistance of the steel surface, but its coefficient of friction is relatively large; CN94116246A discloses a Resin is the adhesive, molybdenum disulfide is the solid lubricant, dicyandiamide is the curing agent, nitrile 40 is the epoxy modifier, and other modified lubricating coatings are added at the same time, which has good wear resistance, lubricity and anti-corrosion properties. Viscous, but it has obvious deficiencies in temperature and corrosion resistance; CN1401933A discloses a wear-resistant and anti-corrosion coating composed of E-type epoxy resin (E12, E10) and corresponding curing agent, but based on E-type epoxy resin For coatings composed of raw materials and substrates, the ambient temperature is difficult to exceed 120°C during long-term use
