Abstract

The invention belongs to the technical field of building materials, and particularly relates to an inorganic ceramic artificial board and a preparation method thereof. According to the inorganic ceramic artificial board, the water consumption is low, generation of pores in the product due to excessive moisture is avoided, and the strength and other mechanical properties of the board are improved;reinforcing materials such as fibers, resin and polyvinyl alcohol do not need to be additionally added; the chemical activity of raw materials is fully utilized; the components are reasonably proportioned, relatively low pressure and temperature are adopted, and through the synergistic effect of the components, the material with high polymerization degree and high compactness is generated in situ;the compressive strength of the prepared inorganic ceramic board can be greater than 120 MPa; water absorption can be less than 0.4%, the linear thermal expansion coefficient can be smaller than 12.0*10<-6> / K, various performance requirements on the ceramic board are met, a high-temperature sintering step is not needed, energy is saved, the economic cost is effectively reduced, no free formaldehyde is released, the better environment-friendly effect is achieved, the fireproof and high-temperature-resistant performance is better, the ceramic board can be completely replaced, and the wide application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an inorganic ceramic artificial board and a preparation method thereof. Background technique [0002] Ceramic plate refers to a class of inorganic non-metallic materials made of natural or synthetic compounds after forming and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance, and oxidation resistance. However, the ceramic industry is an industry with high energy consumption, high emissions, and high resource consumption. The exploitation of other alternative building materials such as wooden floors and stones has caused great damage to the environment due to limited resources. [0003] Artificial board is an important building decoration material in today's society, which can replace natural stone, high-grade ceramics, wood and metal decoration materials. Wood-based panels include organic wood-bas...
