A sintered inorganic quartz stone plate and its production process

Abstract

A sintered inorganic quartz stone plate and its production process according to the present invention, according to the weight percentage, its raw materials are: 325 mesh-400 mesh quartz powder 80%-93%, 1250 mesh quartz powder 0-10%, colored Granite stone powder or quartz powder: 0% to 10%, feldspar powder: 1% to 5%, kaolin: 2% to 6%, pigment: 0 to 2%, firstly mix all the raw materials evenly by mechanical stirring, according to Parts by weight, for every 100 parts of the mixture, add 5‑25 parts of water, 0 to 2 parts of water reducing agent, and 0 to 2 parts of green body strengthening agent, and stir evenly until the mixture can be molded by hand; then the mixture It is sent to the molding press to be pressed into a sheet-shaped green body, and then sent to a drying kiln with integrated functions of drying and ventilation, and then fired into a kiln. The fired finished product has alkali corrosion resistance, UV resistance, Not easy to deform, low water absorption, good antifouling performance, good wear resistance, high strength and good toughness.

Description

technical field [0001] The invention relates to a quartz stone plate, in particular to a sintered inorganic quartz stone plate and its production process. Background technique [0002] At present, quartz stone products are mainly used in kitchen countertops, bathroom countertops, bar counters, coffee tables, floors, and walls. Due to its rich colors, natural colors, and good texture, it can replace natural stone, high-grade ceramics, wood, and metal decorative materials. [0003] At present, the mainstream quartz stone products on the market are resin-type quartz stone plate products. [0004] The resin-type quartz stone plate is made of unsaturated polyester resin, which binds about 90% of the quartz particles in the system to form a plate with a bending strength exceeding 30MPa; the sintered inorganic quartz stone plate in the present invention is based on a small amount of clay- The liquid formed by the feldspar-quartz ternary eutectic system at high temperature binds ab...

AI Technical Summary

Problems solved by technology

In the finished ceramic tile system, glass phase and mullite crystal phase are the main ones, and only a small amount of residual quartz that cannot be melted at high temperature is contained. The whole system of glass phase and mullite crystal phase is sintered and fused into a whole, not stick The composition of the mixture + granular material, the tiles are brittle, poor toughness, easy to chip and break, and the processing loss is large, so it is difficult to apply to the parts that need special-shaped processing such as edge grinding and opening.
