Efficient and lightweight composite thermal insulation material

Abstract

The invention relates to an efficient, energy-saving and level-A1 fireproof composite thermal insulation material. The thermal insulation material is formed by mixing and stirring sepiolite, fibrous brucite, cement 425, an adhesive, a foaming agent, hydrophobic expanded perlite and polystyrene granules in different weights. The appearance of the thermal insulation material is of dry powder fibers in bulk. After the thermal insulation material is mixed and stirred with water, the thermal insulation material can be directly sprayed on the outer wall, inner wall and roof of a building or between stairs according to certain thickness. The thermal insulation material has the characteristics of thermal insulation, energy conservation, flame resistance, environmental friendliness and water prevention, and is simple and rapid to construct. Thus, the thermal insulation material provided by the invention is suitable for the thermal insulation of various house buildings, so as to achieve the efficient and energy-saving effect.

Description

Technical field: [0001] The invention relates to a novel high-efficiency and energy-saving composite thermal insulation material, which is especially suitable for thermal insulation of inner and outer walls of various building structures. Background technique: [0002] At present, my country mainly uses two types of products in terms of building energy conservation and heat preservation. One type uses organic flammable, generally board insulation materials. During construction, fixed facilities such as adhesives and steel grids need to be added, resulting in high construction costs. It is flammable, volatile and falls off, and the surface is prone to cracks, water seepage, and thermal insulation performance reduction; the other type is inorganic thermal insulation mortar. Although it has good fire resistance, it has high thermal conductivity and poor thermal insulation performance, especially not suitable for use in severe cold areas. .
