Organic and inorganic composite insulation material

Abstract

The invention discloses an organic and inorganic composite insulation material which is a composite material prepared from an organic material as aggregate and an inorganic material as a bonder by stirring in a mixed way, moulding and forming at normal temperature or extruding and forming at high temperature. The proportion of the organic material to the inorganic material in parts by weight is (5-25): (75-95). The organic material is polystyrene foam or polyvinyl chloride foam or polyurethane foam. The inorganic material is aluminium silicate geological polymer material. The organic and inorganic composite insulation material prepared by the invention not only has good thermal insulation performance but also is advantageous for bonding to the inorganic material, such as a wall body and the like and is simple for construction and low in cost; and compared with the traditional organic insulation material, the organic and inorganic composite insulation material has the advantages of high strength, difficult combustion, low water absorption, low deformation, air permeability, light weight and the like.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to an organic / inorganic thermal insulation material, which is a thermal insulation material and its products prepared by using an alkali-polymerized aluminosilicate geopolymer material as a bonding material. Background technique [0002] With the country's emphasis on building energy conservation, the energy-saving and thermal insulation industry of building exterior walls has attracted more and more attention. According to the analysis of the Department of Science and Technology of the Ministry of Construction, by the end of 2020, among the newly added 30 billion square meters of housing construction area in the country, 13 billion square meters will be added in cities. If all these buildings achieve 50% energy saving on the existing basis, about 160 million tons of standard coal can be saved every year. Among the more than 40 billion square meters of existing buildings, the total ...

AI Technical Summary

Problems solved by technology

[0006] Disadvantages: poor fire resistance, large fire hazards at the construction site, prone to fires, such as the CCTV building fire, Shanghai Jing'an high-rise fire, many people died, mainly caused by flammable insulation materials; the construction process is complex, the comprehensive cost is high; The quality of follow-up construction is not easy to guarantee, the bonding strength is low, and quality problems such as cracking, falling off, and hollowing of the surface mortar are prone to occur, which restricts architectural decoration.

[0009] Disadvantages: poor fireproof performance, complex process, high requirements on the flatness of the wall substrate, high price (70-90 yuan / m2), poor bonding strength, and short service life

[0012] Disadvantages: the quality is very different, the density of good heat preservation is low, the compressive strength is also low, and the durability becomes poor

[0015] Disadvantages: low strength, strong water absorption, thermal conductivity increases after water absorption, and thermal insulation performance decreases
