Novel wear-resisting plate produced by using waste moulding sand and preparation method of plate

Abstract

The invention discloses a novel wear-resisting plate produced by using waste moulding sand and a preparation method of the plate. The novel wear-resisting plate produced by using waste moulding sand comprises the following raw materials in parts by weight: 40-60 parts of waste moulding sand, 0-15 parts of quartz sand, 22-40 parts of calcium carbonate, 1-7 parts of aluminum oxide, 0-2 parts of sodium nitrate, 2-10 parts of sodium carbonate, 8-20 parts of magnesium carbonate and 1-2 parts of chromium sesquioxide. According to the invention, waste is used as the production raw material, so that the cost for producing the wear-resisting plate is reduced; by taking diopside as the main crystalline phase, the wear-resisting plate is large in hardness, high in strength, corrosion resistant, weather resistant, non-absorbent and free of radioactive dangers; and at the same time, the volume of cargo in storage of the waste moulding sand is decreased, so that the recycling of the waste is realized and the environment pollution is prevented and treated. The wear-resisting plate is prepared by using a melting-calendaring-crystallization process and the product is capable of replacing certain metals or other materials at certain places, so that the cost is reduced and the service life of the equipment is prolonged; and the wear-resisting plate can be widely applied to the fields of electric power, coal, mine, metallurgy, building and the like.
