Abstract

The invention relates to an inorganic environment-friendly manmade art stone and a preparation method thereof. The inorganic environment-friendly manmade art stone is prepared from the following raw materials in parts by mass according to a proportional ratio: 55 to 70 parts of quartz sand particles, 4 to 9 parts of quartz sand powder, 17 to 24 parts of cement, 1 to 4 parts of activity additive, 1to 2 parts of expander, 0.3 to 0.4 part of water reducing agent, 3 to 5 parts of emulsion, 0.05 to 0.1 part of water retention agent, and 3 to 5 parts of water. The inorganic environment-friendly manmade art stone has the advantages that by adding the inorganic activity additive, the condition of common alkaline return of the cement type base plate is avoided; by adopting the expander, the self-shrinkage of the cement type base plate is effectively compensated, and the cracking of a forming plate is reduced; the preparation method is simple, the production technology conditions are easy to control, the product quality is stable, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an inorganic and environment-friendly artificial art stone and a preparation method thereof. Background technique [0002] Artificial art stone slabs are mainly used for kitchen countertops, laboratory countertops, window sills, dining tables, coffee tables, computers, bar counters, commercial plazas, etc. Most of the artificial art stones currently on the market use unsaturated polyester as a binder, and inorganic marble, quartz stone and other scraps as aggregates. Since the binder is unsaturated resin, it is easily aged and deformed after being exposed to rain and sun for a long time outdoors, which affects the use effect and life. Moreover, the organic resin is flammable and not environmentally friendly, lacks natural texture, and is not suitable for living. [0003] The preparation method of an inorganic environment-friendly artificial stone described in the inve...
