Artificial quartz stone sheet material and preparation method thereof

Abstract

An artificial quartz stone sheet material comprises the following raw materials: 4-100 mesh quartz sand, 300-1000 mesh quartz powder, an adhesive, an auxiliary agent and a pigment. A preparation method of the artificial quartz stone sheet material comprises the following steps: (1) adding quartz sand into a high-speed mixer and uniformly stirring at a low speed, then adding quartz powder and stirring at a low speed for 20 s, and then performing high-speed stirring for 30 s to obtain a mixture; (2) doping the pigment into the adhesive, stirring uniformly, pouring into the mixture, and performing high-speed for 50 s to form a material; (3) sending the mixed material into a beater for further dispersing the material through beating, then metering and sending to a material distributor for material distribution, then sending into a plating die, sending the plating die into a molding press and molding under the conditions of vacuum, shaking and pressurization, so as to form a sheet material; and (4) sending the molded sheet material into a curing box for curing, and after curing is finished, and performing thickness setting and polishing deep processing, so as to prepare the artificial quartz stone sheet material. The artificial quartz stone sheet material has the advantages of low resin usage amount, short press time, high production efficiency, low cost, good compactness and the like.

AI Technical Summary

Problems solved by technology

In China, due to the technical blockade of the western powers, the production equipment of domestic quartz stone is relatively backward. In order to improve the pass rate of products, major quartz stone manufacturers have to increase the amount of resin added and prolong the pressing time of the plate.

As a result, the resin content of the quartz stone produced by most domestic quartz stone manufacturers is relatively high, and the resin content is generally above 10%, and the production time is long, which increases the production cost of the product and finally increases the selling price of the product.

In addition, the high resin content leads to a low thermal expansion coefficient of the finished quartz stone, poor durability of the plate, easy aging, fading, low fire rating, and poor heat resistance, which greatly shortens the service life of the plate
