Anti-ultraviolet calcium silicate board prepared from industrial waste residue and production process thereof
The invention relates to the technical field of calcium silicate board preparation, in particular to a calcium silicate board prepared from industrial waste residue and a production process thereof. The raw materials for preparation of the calcium silicate board from industrial waste residue include, by dry weight percentage, 35-45 parts of blast furnace steel slag; 5-15 parts of fly ash; 10-25 parts of desulfurization gypsum; 1-5 parts of mica powder; 20-35 parts of an anti-ultraviolet ageing agent; 5-10 parts of sanding powder; 0.05-0.1 part of polyacetamide. The raw materials are prepared into a mixed material. Specifically, the blast furnace steel slag, fly ash and desulfurization gypsum are all solid wastes discharged from smelting plants. The calcium silicate board product made by the process provided by the invention meets the various index requirements of the national standard, not only can reduce the pollution of industrial solid waste discharge to the environment, but also can achieve the economic and social benefits of turning "waste" into wealth. Layered dihydroxyl composite metal hydroxide is a multistage superimposed layer structure composed of a layered host double hydroxide laminate and interlayer guest anions, has excellent physical shielding effect to ultraviolet, and can effectively improve the anti-ultraviolet aging properties.
