The invention discloses a high-strength artificial quartz stone plate and a production process thereof. The high-strength artificial quartz stone plate is made from, by weight, 40-60 parts of 4- to 10-mesh quartz sand, 25-35 parts of 400- to 600-mesh quartz powder, 30-40 parts of binder, 10-20 parts of cullet, 5-10 parts of aluminum silicate fiber, 10-15 parts of organic bentonite, 20-25 parts of zirconia ceramic powder, 30-40 parts of sodium silicate, 15-20 parts of fly ash, 0.5-1 part of isopropyl tri(dioctylpyrophosphate) titanate, and 0.2-0.3 part of pigment. The artificial quartz stone plate produced by the production process has the advantages of light weight, uniform density, bright color, rich pattern, high impact resistance, high wear resistance, fine heat resistance, fine weatherability, deformation resistance, scratch resistance, aging resistance, coloring resistance, environment friendliness, no pollution and the like, has high performance indexes in terms of acid and alkali resistance, slat spray resistance, gasoline resistance and the like in organic solvents, and is durable and fully as effective as simulation natural stone.
