Problems solved by technology

At present, the main adhesives of artificial quartz stone are organic adhesives such as unsaturated resin and acrylic resin, which have the disadvantages of poor heat resistance and aging resistance, and are easy to age, not resistant to high temperature and poor in fire resistance when used.
[0003] Inorganic adhesives such as cement, water glass, gypsum, etc. have the advantages of good fire resistance and aging resistance, but their application in artificial stone has problems such as easy cracking and long curing time. Insufficient results lead to poor mechanical and decorative properties of conventional inorganic artificial stone, and the application has been greatly limited

Abstract

The invention discloses a novel inorganic artificial quartzite and a preparation method thereof and belongs to the field of building decorative materials. The novel inorganic artificial quartzite provided by the invention comprises the following raw materials by weight parts: 2-20 parts of inorganic polymer A components, 4-20 parts of inorganic polymer B components, 50-90 parts of aggregates and 0.1-1.0 part of additives. The preparation method provided by the invention comprises the following steps: uniformly stirring the components, such as inorganic polymers, pigments, aggregates, and additives, according to a certain technology, and then performing the processes of distributing materials, vacuumizing, vibrating, pressing and forming, fixing thickness, curing, polishing, cutting, protecting and the like, thereby obtaining the inorganic artificial quartzite. The production technology for the inorganic artificial quartzite is simple; during the production process, a plate surface is free from being cracked and warped; the mechanical property is excellent, the glossiness is high and the hardness is high; and the novel inorganic artificial quartzite belongs to a novel environment-friendly product which can be widely applied to various indoor and outdoor decorative and fitting-out projects.

Description

technical field [0001] The invention relates to an inorganic artificial quartz stone, in particular to a novel inorganic artificial quartz stone and a preparation method thereof, belonging to the technical field of building decoration materials. Background technique [0002] Artificial quartz stone is a new type of building decoration material. It is favored due to its excellent properties such as high bending strength, high gloss, high hardness and wear resistance. It is widely used in places with high requirements on materials such as floors, walls, etc. At present, the main adhesives of artificial quartz stone are organic adhesives such as unsaturated resin and acrylic resin, which have disadvantages such as poor heat resistance and poor aging resistance, and are easy to age, not resistant to high temperature and poor in fire resistance when used. [0003] Inorganic adhesives such as cement, water glass, gypsum, etc. have the advantages of good fire resistance and aging ...
