Method for preparing organic-inorganic composite thermal-insulating heat-preservation material

Abstract

The invention belongs to the field of building heat preservation materials and discloses a method for preparing an organic-inorganic composite thermal-insulating heat-preservation material. The composite thermal-insulating heat-preservation material is prepared by means of laying: a release membrane, inorganic powder packing, a low-density hollow microsphere/glass fiber mesh, an aerogel, a phenolic resin solution/glass fiber mesh, inorganic powder packing and a release membrane, and by using a hot-pressing integral molding method after laying is completed. In addition to light weight and goodthermal insulation, mechanical properties of the composite thermal-insulating heat-preservation material disclosed by the invention are improved to a certain extent, and the composite thermal-insulating heat-preservation material has the potential of large-scale application in fields of heat preservation and thermal insulation of inner walls of buildings, and the like.

Description

technical field [0001] The invention belongs to the field of building thermal insulation materials, and in particular relates to a preparation method of an organic-inorganic composite thermal insulation material. Background technique [0002] Building heat insulation is an important aspect of saving energy, improving the living environment and using functions. The core of building energy conservation in my country is to innovate the building envelope and heating system. Building energy consumption generally accounts for 30-40% of the total energy consumption of human beings, most of which are heating and air conditioning energy consumption, so building energy conservation is of great significance. [0003] Today, global thermal insulation materials are developing in the direction of high efficiency, energy saving, thin layer, heat insulation, waterproof and external protection. At present, in my country, traditional thermal insulation materials such as rock wool, glass wool,...
