Sintered inorganic quartz stone plate and production process thereof

Abstract

The invention discloses a sintered inorganic quartz stone plate and a production process thereof. The sintered inorganic quartz stone plate comprises the following raw materials in percentage by weight: 80-93% of 325-400-mesh quartz powder, 0-10% of 1250-mesh quartz powder, 0-10% of colored granite rock powder or quartz powder, 1-5% of feldspar powder, 2-6% of kaolin and 0-2% of a pigment. The production process comprises the following steps: firstly, uniformly mixing all raw materials in a mechanical stirring mode, adding 5-25 parts of water, 0-2 parts of a water reducing agent and 0-2 partsof a blank reinforcing agent in parts by weight, and performing uniform stirring till a mixed material state meeting the condition that molding can be achieved through pinching by hands; and conveyingthe mixed material into a molding press, pressing the mixed material into a flaky blank, conveying the flaky blank into a drying kiln with integrated functions of drying and air exhaust, further feeding the mixed material into a sintering kiln, and performing sintering so as to obtain a finished product which has the characteristics of alkali corrosion resistance, ultraviolet resistance, deformation prevention, low water absorption rate, good antifouling performance, good wearing 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.
