Problems solved by technology

[0004] At present, composite plate production and molding products such as: quartz stone ceramic composite plate, quartz stone aluminum honeycomb composite plate, marble ceramic composite plate, are artificial quartz stone plate or marble thick plate sawn into 4-6mm thin plate, or quartz The stone material is pressed into a plate with a thickness of 8-10mm, and the thickness is set to 4-6mm on both sides, and then combined with ceramic tiles or aluminum honeycomb plates. This production process requires very high surface flatness of ceramic tiles and quartz stone sheets. It must also be scraped before compounding, otherwise it is difficult to ensure the flatness of the ceramic plate and affect the quality of the plate after compounding
[0005] At present, the traditional method is to directly compound the quartz stone plate with the tile layer through glue. This processing method has the following defects: 1. The hardness of the artificial quartz stone plate and marble plate is very high and the limi

Abstract

The invention relates to the technical field of a stone decoration material, and particularly relates to a composite quartz board and a manufacturing process thereof. The manufacturing process comprises the following steps: weighing a mortar raw material for molding a quartz layer, and stirring for standby application; laying a layer of kraft paper or PVC film on the bottom surface of a mold, uniformly pouring the stirred mortar raw material into the mold, laying a piece of fibrous web on the surface of the flattened mortar raw material, then laying a layer of kraft paper or PVC film on the fibrous web, and vacuumizing, vibrating and compacting to obtain an uncured quartz mortar layer; and removing the kraft paper or PVC film on the fibrous web, attaching a ceramic tile coated with modified glue onto the surface of the fibrous web, then compacting, curing at a high temperature, cooling, molding, and grinding for determining the size to obtain the composite quartz board. The quartz layer is unlikely to separate from the ceramic tile, the adhesive strength is high, the production process is simple, no air bubble is produced during the compositing process, and the prepared composite quartz board is high in strength and long in service life.

Description

technical field [0001] The invention relates to the technical field of stone decoration materials, in particular to a quartz stone composite board and a production process thereof. Background technique [0002] Composite surface material, also known as artificial quartz stone, is deeply loved by its many advantages such as rich and bright colors, no radiation, wear resistance, pressure resistance, scratch resistance, corrosion resistance, anti-aging, anti-permeation, hard as a stone, and bright as a mirror. It is loved by the majority of users and has gradually become a new type of decorative material that replaces traditional stone materials such as natural marble, granite, and ordinary artificial marble. [0003] With the continuous maturity of product technology and market, the quartz stone market has been activated, and consumer demand continues to increase. At present, quartz stone surface materials have been widely used in walls, countertops, fireplaces, fountains and...
