Wear-resistant paint prepared from steel slag, wear-resistant paint coating block and preparation method

Abstract

The invention relates to a wear-resistant paint prepared from steel slag, a wear-resistant paint coating block and a preparation method. The wear-resistant paint is prepared from the raw materials steel slag, epoxy resin and a curing agent, wherein the steel slag are in the two particle size ranges of 1-1.5mm and 3-3.5mm. The wear-resistant paint prepared from steel slag provided by the invention adopts steel slag as the main raw material, has no requirement for steel slag components, only requires the particle size, therefore deep treatment is unnecessary for steel slag, and waste can be turned into things of value, thus fundamentally solving the problems of difficult steel slag treatment and high investment. As a novel functional paint, the wear-resistant paint has large consumption, through popularization of the wear-resistant paint, at least 0.16 ton of steel slag can be treated every year, and because of the low price of steel slag, the cost of the wear-resistant paint mainly lies in cheap epoxy resin and curing agent, the wear resistance is equivalent to that of ceramic wear-resistant paint and silicon carbide wear-resistant paint, however the cost is less than half of the two, therefore the wear-resistant paint prepared from steel slag has broad popularization prospect.

Description

technical field [0001] The invention relates to paint, in particular to a wear-resistant paint prepared from steel slag, a wear-resistant paint coating block and a preparation method. Background technique [0002] Steel slag is a kind of solid waste discharged after steelmaking. In the process of steelmaking, the oxides produced by the oxidation of various elements in the metal charge, the eroded furnace lining and repair materials, and impurities brought in by the metal charge, such as Silt, and waste formed by deliberately added slagging materials, such as lime, fluorite, deoxidizer, etc. Steel slag is mainly composed of oxides of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus, etc. The main mineral phases are solid solutions formed by tricalcium silicate, dicalcium silicate, calcium magnesium olivine, calcium magnesium rhodoxene, calcium aluminate ferrite, and oxides of silicon, magnesium, iron, manganese, and phosphorus.

AI Technical Summary

Problems solved by technology

[0006] However, ceramic wear-resistant coatings and silicon carbide wear-resistant coatings have been highly praised in the market today. The coatings have high hardness and good wear resistance, but the required raw materials are expensive and the preparation process is complicated, so the prices of these two wear-resistant coatings are very high. Expensive, poor promotion, especially ceramic wear-resistant coatings, and a large amount of waste gas and other pollutants will be generated during the manufacturing process, which is not conducive to environmental protection
