Problems solved by technology

Alumina and zirconia are two common components in ceramic materials. Alumina has excellent properties such as low specific gravity and high temperature resistance. It is widely used in the field of ceramic materials, but its flexural strength and fracture toughness are low; zirconia has Good flexural strength, known as "ceramic steel", but its high specific gravity usually increases the weight of the finished product

Abstract

The invention discloses an environment-friendly thermal-insulation building composite ceramic and a preparation method thereof. The environment-friendly thermal-insulation building composite ceramic is prepared from the following raw materials in parts by weight: 20-35 parts of ceramic waste, 20-30 parts of building powder waste coarse aggregate, 15-30 parts of zeolite powder, 10-20 parts of zinc oxide, 8-15 parts of ceramic clay, 20-35 parts of bentonite, 10-12 parts of granite waste, 11-22 parts of sodium humate, 7-15 parts of aluminum nitrate, 8-18 parts of nickelous nitrate, 5-10 parts of sintering aid and 5-10 parts of polyethyleneglycol. The whole body is composed of a ceramic material, and the application temperature is up to 900 DEG C. The composite ceramic is completely fireproof, has the advantages of high strength and long service life, can substitute the existing walling material and inflammable thermal-insulation material, and greatly enhances the safety of building constructions. The ceramic waste is used as the production raw material, thereby greatly lowering the production cost of the thermal-insulation building material. The ceramic waste occupies abundant land and causes environmental pollution; and the ceramic waste is used as the industrial raw material to implement comprehensive utilization on industrial wastes, thereby implementing energy saving, environment friendliness and pollution abatement.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to an environment-friendly thermal insulation building composite ceramic and a preparation method thereof. Background technique [0002] With the increase of major fire accidents associated with wall insulation materials, the construction field proposes to adopt methods such as fire isolation and no cavity in the external wall insulation system, which can solve the problem of easy flame propagation and diffusion in the combustion characteristics of organic insulation materials. Defects, so as to avoid fire accidents caused by flame spread and spread caused by flammable insulation materials. However, the research on fireproof structure cannot solve the temperature resistance and flame resistance of organic thermal insulation materials on the wall structure, as well as the release of smoke and toxic gas by organic thermal insulation materials in a fire, and the melting of...
