A light-weight ceramic composite thermal insulation building material and its preparation method

Abstract

The invention discloses a novel lightweight composite heat-insulation ceramic construction material. The novel lightweight composite heat-insulation ceramic material mainly comprises, by weight, 40-55 parts of ceramic waste, 5-15 parts of calcium-carbonate-based waste, 1-10 parts of clay, 2-15 parts of bentonite and 6-8 parts of foaming agent, and is obtained by subjecting the raw materials in the weight part ratio to smashing, firing and follow-up treatment under a certain conditions. The novel lightweight composite heat-insulation ceramic construction material has the advantages that the ceramic waste is taken as a production raw material, so that comprehensive utilization of industrial waste, energy conservation and environment protection are achieved; the prepared novel lightweight composite heat-insulation ceramic construction material is low in cost and density, small in heat conduction coefficient, high in compressive strength and tensile strength, capable of proofing fire completely and the like.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel lightweight ceramic composite thermal insulation building material and a preparation method thereof. Background technique [0002] Background 1: 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, low Defects that are easy to spread, so as to avoid fire accidents caused by flame spread and spread caused by flammable thermal insulation materials. However, the research on fire-proof 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 poisonous gas by organic thermal insulation materials in a fire, and the melting of thermoplastic organic thermal i...

AI Technical Summary

Problems solved by technology

However, the research on fire-proof 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 poisonous gas by organic thermal insulation materials in a fire, and the melting of thermoplastic organic thermal insulation materials such as EPS and XPS in the combustion process. , dripping and other issues

This means that the inherent defects of low fire protection level, poor stability and durability in organic thermal insulation material technology can no longer meet the social requirements for building thermal insulation materials.

[0003] Background 2: With the rapid development of social economy and ceramic industry, the waste of ceramic industry is increasing day by day. The disposal of these wastes requires a lot of social resources, which partially limits the development of urban economy and the sustainable development of ceramic industry.

At present, the treatment and utilization of ceramic industry waste in my country is relatively low, and a large amount of waste slag occupies public resources and pollutes the environment.

With the increase of the production capacity of the ceramic industry, the amount of waste is increasing. A large amount of ceramic waste is no longer a problem that can be solved simply by landfilling. The accumulation of ceramic waste occupies the land, and the fine dust affects the quality of the local air. The filling of ceramic waste Burying consumes a lot of manpower and material resources, and also pollutes groundwater quality. How to turn waste into treasure and make rational use of ceramic waste has become a top priority for science and technology and environmental protection departments
