Abstract

The invention relates to a compound silicate external wall insulation material. The compound silicate external wall insulation material is prepared from, by weight, 15-20 parts of caustic sludge, 30-50 parts of cement, 50-55 parts of coal ash, 31-36 parts of sepiolite, 10-14 parts of composition fiber materials, 6-10 parts of anti-cracking fiber, 10-14 parts of a dispersing agent, 3-5 parts of a high efficiency slushing agent and 1-5 parts of a foaming agent. The compound silicate external wall insulation material meets the requirement for environment protection, does not contain asbestos or perlite, is small in density, good in heat insulation performance, good in anti-cracking performance, capable of utilizing caustic sludge, environmentally friendly, low in cost, and good in fireproof and waterproof performance.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a composite silicate external wall insulation material. Background technique [0002] Composite silicate insulation material is a closed-pore mesh structure material connected by a solid matrix. It is a special non-metallic mineral containing aluminum, magnesium and silicate as the base material, doped with a certain amount of auxiliary raw materials and fillers. A material prepared by adding certain chemical additives. The product has low thermal conductivity, low heat loss, less materials, non-toxic, no environmental pollution, and is an ideal insulation material. Composite silicate insulation material has the advantages of low thermal conductivity, simple production process, and good insulation effect, which has attracted more and more attention. [0003] However, the current composite silicate insulation materials do not meet environmental protection requirements because they con...
