Abstract

An insulating material for the external surface of wall is proportionally prepared from waste paper, light insulating aggregate, powdered coal ash, cement, calcium lime, foaming agent, pulping agent, fire-proof agent, adhesion increaser, water-proofing agent and activator.

Description

Technical field: [0001] The invention relates to the thermal insulation material outside the wall. Background technique: [0002] Existing thermal insulation materials for external walls, as described in the patent application document with the publication number CN1458112, are made of the following raw materials in proportion by weight: cement 50-55, polystyrene particles 10-15, fly ash 20-25, Light calcium carbonate 1-5, heavy calcium carbonate 5-10, cellulose fiber 0.1-0.5, methyl cellulose 0.1-0.3, starch ether 0.1-0.2, foaming agent 0.1-0.2, air-entraining agent 0-0.2 . Mix and pack the above-mentioned powdered raw materials. Because it is difficult for organic materials such as polyphenylene particles to be bonded with inorganic materials to form a whole, it is necessary to use expensive adhesives or make an auxiliary fixing layer of barbed wire. The effect is reduced. After a fire, organic matter releases large amounts of toxic gases that harm disaster relief and ...
