Abstract

The invention relates to geopolymer-based inorganic artificial stone. The traditional artificial stone has the shortcomings of easy yellowing, deformation and aging, high cost, highly-possible fire or melting after receiving heat radiation and the like. The geopolymer-based inorganic artificial stone provided by the invention is prepared from the following raw materials in percentage by mass: 5-15% of water glass, 5-20% of superfine slag powder, 60-80% of stone particles, 0.1-0.3% of pigment, 0.1-0.5% of redispersible latex powder, 1-3% of fiber and 3-5% of water. The geopolymer-based inorganic artificial stone provided by the invention has the characteristics of stable structure, high strength, good wear resistance, environment-friendly raw materials, simple production process, low cost and high smooth finish, and is non-toxic and environment-friendly. Apart from low cost, high product hardness and good surface smoothness, the geopolymer-based inorganic artificial stone also has the advantages that the production process is simple and convenient, the raw materials are widely available, the production process is environment-friendly, and the raw materials are environment-friendly.

Description

technical field [0001] The invention relates to a geopolymer-based inorganic artificial stone, which belongs to the technical field of new materials. Background technique [0002] As a decorative material for interior and exterior decoration of buildings, floors and squares, stone is favored by the masses because of its high-end decoration, luxury, not easy to damage, good durability, and good cleanliness. my country is a large country of stone production, but stone is a natural resource and a non-recyclable resource. Due to long-term and large-scale mining, there are fewer and fewer mineral resources that can be used as stone. Therefore, using the scraps of stone mining to prepare artificial stone has become the development direction of stone. [0003] The main materials of traditional artificial stone are resin, crushed stone, pigment and other additives. Under a certain pressure, after the polymerization process of resin, it finally becomes a stone-like material. Under a...
