The invention relates to the technical field of the preparation of calcium silicate boards, in particular to an oil-resistant high temperature resistant calcium silicate board prepared from industrial waste residues and a production technology of the oil-resistant high temperature resistant calcium silicate board. The oil-resistant high temperature resistant calcium silicate board consists of the following components in percentage by weight: 38-45% of blast furnace steel slags, 5-10% of fly ash, 5-20% of desulfurized plaster, 3-5% of mica powder, 15-17% of a polyurethane elastomer, 5-7% of a tetrafluoroethylene -hexafluoropropylene copolymer, 5-9% of isoprene rubber and 5-10% of policapram which are compounded into mixed materials, wherein the blast furnace steel slags, the fly ash and the desulfurized plaster are solid waste discharged by smelteries. The calcium silicate board product produced by the method disclosed by the invention meets the requirements of indexes of standards of China, not only can reduce the pollution to environment, which is caused by discharged industrial solid waste, but also can have the economic and social benefits of turning waste into wealth. The added polyurethane elastomer has excellent abrasion resistance and excellent oil resistance, can organically combine a polar polymer and polypropylene into a whole, and can effectively improve the mechanical property of the polypropylene; the added fluorine rubber has the characteristics of high temperature resistance, high oil resistance and the like, and the other fillings which are added can improve other physical properties and processing properties.
