Concrete bundle superimposed thermal insulation material and preparation method thereof

Abstract

The invention discloses a concrete bundle superimposed 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 biomassash, 12-19% of saw dust, 3-13% of old clothes fibers, 13-40% of cement, 5-15% of lightweight aggregate and 0.2-0.5% of an additive, and is composed of an inner wall plate, an outer wall plate, a thermal insulation partition plate, an air beam, a trough plate, an installation corner, a bundle end plug and concrete, wherein the surface of the air bundle is a rough surface, and the thermal insulation partition plate is installed between the inner wall plate and the outer wall plate. According to the invention, air beams are arranged in a multilayer staggered manner, so that the thermal bridge length is increased and the thermal resistance is increased so as to increase the thermal resistance of the thermal insulation building material and reduce the heat transfer coefficient of the thermal insulation building material; and the produced thermal insulation building material is high in strength through a special formula, the A-grade fireproof smokeless non-toxic effect is achieved through inorganic materials, and the environmentally-friendly building material is manufactured through industrial solid waste, old clothes fibers and other resources and is economical and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete bundle laminated thermal insulation material and a preparation method thereof. Background technique [0002] Building insulation materials are one of the important materials for promoting building energy conservation. Generally speaking, they are divided into three categories: inorganic, organic and composite insulation materials. Among them, the most used are organic and inorganic insulation materials. my country began to implement building energy conservation work in 1986. At the beginning, it mainly used 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 Technica...

AI Technical Summary

Problems solved by technology

[0003] Defects and deficiencies of the existing technology: organic thermal insulation materials and organic-inorganic composite thermal insulation materials cannot overcome fire safety problems; the 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
