Abstract

The invention discloses a high-strength man-made quartz plate and a preparation method thereof. The plate comprises the following raw materials: unsaturated polyester resin, an inorganic material, a pigment, a coupling agent, a strength increasing material, a promoter and a curing agent. The preparation method includes: weighing all the raw materials according to a weight ratio, mixing uniformly, filling a mould with the material mixture, vibrating under vacuum, degassing by vacuum pressing, curing and forming at a medium temperature, and performing surface sanding processing to obtain a finished product. Beneficial effects of the man-made quartz plate and the preparation method thereof are that: the man-made quartz plate has increased plate density, increased rupture strength, increased compressive strength, increased falling-ball impact strength, reduced water adsorption rate, improved comprehensive performance indexes, and prolonged service lifetime; the application fields of finished products of the man-made quartz plate are largely increased; and the strength increasing material is added, thus largely increasing the strength of the man-made quartz plate.

Description

[0001] technical field [0002] The invention relates to artificial building materials, in particular to a high-strength artificial quartz stone plate and a preparation method thereof. [0003] Background technique [0004] At the beginning of this century, artificial quartz stone was invented in Spain. This material is widely used in furniture, laying floors and walls of various buildings. Artificial quartz stone products are generally produced by unsaturated polyester resin and quartz stone powder filler, but at present, artificial quartz stone plates have low strength, easy cracking, and fracture, which seriously affect the service life of artificial quartz stone. Therefore, developing a high-strength artificial quartz stone plate is a difficult problem that those skilled in the art have been solving. [0005] Contents of the invention [0006] In order to improve the strength of the artificial quartz stone and prolong the service life of the artificial quartz stone,...
