Preparation Method of Concrete Bundle Laminated Thermal Insulation Material

Abstract

The invention discloses a preparation method of a concrete bundle laminated thermal insulation material, which comprises the following raw materials in parts by weight: 20-40% of slag, 20-40% of fly ash, 20-40% of biomass ash, sawdust 12~19%, old clothes fiber 3~13%, cement 13~40%, light aggregate 5~15%, additive 2~5‰, the concrete bundle laminated insulation material is composed of inner wall panel, outer wall panel, It is composed of a thermal insulation baffle, an air bundle, a slot plate, an installation angle, a bundle end block and concrete, the surface of the air bundle is a rough surface, and the thermal insulation partition is installed between the inner wall panel and the outer wall panel. The invention adopts multi-layer dislocation arrangement of air beams to increase the length of thermal bridges and increase thermal resistance, thereby increasing the thermal resistance of thermal insulation building materials and reducing the heat transfer coefficient of thermal insulation building materials. Inorganic materials are used to form A-grade fire-proof, smoke-free and non-toxic. By using industrial solid waste, old clothing fibers and other resources, it is economical and environmentally friendly to manufacture green building materials.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing a concrete bundle laminated thermal insulation material. Background technique [0002] Building thermal insulation materials are one of the important materials to promote building energy conservation, generally divided into three categories: inorganic, organic and composite thermal insulation materials. Among them, the most used are organic and inorganic insulation materials. China began to implement building energy-saving work in 1986. At the beginning, it was mainly based on inorganic insulation materials such as rock wool, glass wool, expanded perlite, foamed concrete, and foam glass. With the gradual increase of energy-saving standards from 30% and 50% to 65% and 75%, on January 24, 2019, the Ministry of Housing and Urban-Rural Development of the People's Republic of China and the State Energy Consumption Building Technical Standards, which ...

AI Technical Summary

Problems solved by technology

[0003] Defects and deficiencies of the prior art: organic thermal insulation materials and organic-inorganic composite thermal insulation materials cannot overcome fire safety problems; initial inorganic cotton, foamed concrete, foam glass, etc. have high thermal conductivity, and with the improvement of energy-saving standards, the thickness of thermal insulation materials If it is too large, it will seriously affect the usable area of ​​the building, and it does not conform to traditional living habits
