Inorganic fiber toughened inorganic composite artificial stone panel and preparation method thereof

An inorganic fiber toughened inorganic composite artificial stone panel, comprising a surface layer and a toughened base layer,

• wherein the surface layer includes materials having the following components in parts by weight:
• 40-70 parts of quartz sand, 10-30 parts of quartz powder, 20-45 parts of an inorganic active powder, 0.5-4 parts of a pigment, 0.3-1 parts of a water reducing agent and 3-10 parts of water,
• wherein the toughened base layer includes materials having the following components in parts by weight:
• 40-60 parts of the inorganic active powder, 45-65 parts of sand, 0.8-1.5 parts of the water reducing agent, 6-14 parts of water, 0.4-2 parts of an inorganic fiber and 0.8-2.5 parts of a toughener, and
• wherein the inorganic active powder is mainly composed of pure white Portland cement doped with an active powder, the pure white Portland cement has a strength grade of more than 42.5, and the active powder is at least one selected from the group consisting of white silicon powder, mineral powder, nano calcium oxide, nano silicon oxide, and sintered high white kaolin powder.
