Abstract

The invention belongs to the technical field of building materials, and particularly relates to a solid waste-based inorganic artificial stone plate and a preparation method thereof. The solid waste-based inorganic artificial stone plate comprises, by weight, 46-66 parts of a solid waste-based material, 90-165 parts of quartz sand, 4-12 parts of an excitant, 7-16 parts of water, 0-2 parts of a water reducing agent and 0-10 parts of an inorganic pigment. The water consumption is low, generation of pores in the product due to excessive moisture is avoided, and the strength and other mechanical properties of the plate are improved; reinforcing materials such as fibers, resin and polyvinyl alcohol do not need to be additionally added, the chemical activity of solid waste is fully utilized, allthe raw materials are matched and used in proportion, that is, the solid waste-based inorganic artificial stone plate with high polymerization degree, high compactness and high strength can be generated in situ through the coordination effect of all the components, the mechanical property requirement of the artificial stone plate is met, the economic cost is effectively reduced, no free formaldehyde is released, and the solid waste-based inorganic artificial stone plate is more environmentally friendly, better in fireproof and high-temperature-resistant performance and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a solid waste-based inorganic artificial stone plate and a preparation method thereof. Background technique [0002] Artificial stone slabs are important building decoration materials in today's society, which can replace natural stone, high-grade ceramics, wood and metal decoration materials. Artificial stone slabs include organic artificial stone slabs and inorganic artificial stone slabs. Organic boards generally use urea-formaldehyde resin, phenolic resin and melamine-formaldehyde resin as adhesives, also known as "trialdehyde glue", "trialdehyde glue" and its products will continuously release formaldehyde and phenol during production, curing and use. Such small molecular toxic substances pollute the ecological environment to varying degrees and endanger human health; the organic sheet is easy to soften and expand after being heated, the higher the co...
