Problems solved by technology

The artificial quartz stone products in the prior art are generally composed of unsaturated polyester and quartz sand filler. Although the technology is mature, the unsaturated polyester resin has a relatively high water absorption rate in a humid environment and is prone to deformation, resulting in artificial quartz stone. When the board is used for floor decoration, it often warps under the action of moisture and external force

Abstract

The invention discloses an artificial quartz sheet for ground pavement, and its preparation method, and belongs to the field of artificial quartz production. The artificial quartz sheet is obtained through vibration and curing molding of main materials comprising an organic silicon resin prepolymer and an inorganic silicon filler. Compared with artificial quartz sheets in the prior art, the artificial quartz sheet for ground pavement has the advantages of no warping in the curing or use process, good ageing resistance, good chemical medicine resistance, high rupture strength, high compressive strength and very good popularization application value.

Description

technical field [0001] The invention relates to the field of artificial quartz stone production, in particular to an artificial quartz stone plate used for ground paving. Background technique [0002] Artificial quartz stone is widely used in the decoration of kitchens, stoves, window sills and other aspects due to its bright appearance, excellent scratch resistance and dirt resistance. Artificial quartz stone products in the prior art are generally composed of unsaturated polyester and quartz sand fillers. Although the technology is mature, the unsaturated polyester resin has a relatively high water absorption rate in a humid environment and is prone to deformation, resulting in artificial quartz stone When the board is used for floor decoration, it often warps under the action of moisture and external force. Contents of the invention [0003] The technical task of the present invention is to provide an artificial quartz stone plate for ground paving to address the above...
