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.

Abstract

The invention relates to the technical field of building materials, in particular to a waste ceramic composite building material and a preparation method and application thereof, and the waste ceramic composite building material is prepared from the following raw materials in parts by weight: 100-150 parts of waste ceramic powder; 1-4 parts of a surface modified coupling agent; 500-1000 parts of a fire-resistant high polymer material; the waste ceramic powder is subjected to surface modification to improve the compatibility of the waste ceramic powder and the fire-resistant high polymer material, then the waste ceramic powder and the high polymer material are blended, the waste ceramic powder is a flame-retardant or non-combustible material, and at the moment, under the blending action of a large amount of the waste ceramic powder, the fire resistance of the composite material is effectively improved; secondary utilization of the waste ceramic powder is realized, and the composite material with excellent fire resistance is prepared and applied to the building materials.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waste ceramic composite building material and its preparation method and application. Background technique [0002] With the development of the construction industry, the waste ceramics produced in the construction industry is also quite alarming. For example, the total daily industrial waste produced by each production line in Faku County Ceramics City, Liaoning Province is more than 4,800 tons. The generation of these wastes has not been effectively controlled. The disposal and recycling of waste, and the generation and elimination of waste have affected and restricted the environmental quality and development space of the Northeast Porcelain Capital. Today, as environmental protection has attracted more and more attention from the world, how to collect and process ceramic waste for reuse is an important issue. The important problem that needs to be considered at p...
