Premixed inorganic paste thermal insulation material

Abstract

The invention discloses a premixed inorganic paste thermal insulation material which comprises the following raw materials in parts by weight: 50-60 parts of an inorganic composite cementing material, 5-10 parts of glass beads, 5-10 parts of mica powder, 3-8 parts of horn powder, 15-20 parts of expanded perlite, 5-12 parts of diatomite, 5-12 parts of white cotton, 5-10 parts of rare earth, 5-15 parts of cellulose ether, 1-3 parts of a defoaming agent, 50-60 parts of water, 5-15 parts of polypropylene cellosilk, 5-8 parts of a reinforcing agent, 10-15 parts of steel slag micropowder, 10-15 parts of slag micropowder and 3-5 parts of a retarder. According to the inorganic thermal insulation paste material, the polypropylene fibers in the component materials have the excellent characteristics of high strength, good elasticity, wear resistance, corrosion resistance and the like, collapse of the paste material under the condition of high-temperature heating can be prevented, meanwhile, the polypropylene fibers also have relatively high heat resistance, and the physicochemical properties of the paste material are maintained. Besides, the steel slag micropowder is added into the preparation formula, so that the preparation cost is greatly reduced.

Description

technical field [0001] The invention relates to a premixed inorganic paste-like thermal insulation material, in particular to the technical field of thermal insulation paste preparation. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. According to the properties of the material, it is divided into organic and inorganic insulation materials. [0003] Among them, the inorganic thermal insulation material in the thermal insulation material is a Class A non-combustible green energy-saving product, which is a Class A non-combustible thermal insulation material with very high safety performance. Yintong's inorganic active wall thermal insulation material layer is firmly bonded to the base wall ...

AI Technical Summary

Problems solved by technology

[0004] However, there is less research on inorganic thermal insulation materials in the prior art, resulting in less research on inorganic thermal insulation layer materials, especially the thermal insulation paste in thermal insulation materials.

With the acceleration of urban construction in our country, and based on the excellent effect of thermal insulation paste, it is necessary to use a large amount of thermal insulation paste, and the existing thermal insulation materials are of poor quality, not only poor in fire resistance, but also poor in physical properties such as compression resistance.

Aiming at the deficiencies in the prior art, there is no thermal insulation paste with better performance so far
