Abstract

The invention relates to the technical field of a heat insulation material, in particular to a light-weight anti-cracking cement foaming heat insulation plate, The heat insulation plate is prepared from the following ingredients: 70 to 80 parts of Portland cement, 25 to 30 parts of pulverized fuel ash, 15 to 20 parts of nanometer bentonite, 10 to 18 parts of lightweight ceramic powder elastomers,3 to 6 parts of inorganic fiber, 2 to 5 parts of water glass, 1 to 1.4 parts of water reducing agents, 7 to 10 parts of foaming agents, 1.3 to 2.5 parts of foam stabilizing agents and 250 to 280 partsof water, wherein the lightweight ceramic powder elastomer is a novel material formed by compounding porous ceramsite micro powder and polyurethane elastomers; the nanometer bentonite uses interlayercation as sodium bentonite of sodium ions; the water reducing agents are lignosulfonate or naphthalenesulfonate water reducing agents; the foaming agents are hydrogen peroxide; the foam stabilizing agents are calcium stearate modified by a nanometer intercalation technology. The heat insulation plate has the advantages that the flame retardant performance is high; the material is light; the goodpressure-resistant performance and anti-impact performance are realized; fracture cannot easily occur.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a lightweight anti-cracking cement foam thermal insulation board. Background technique [0002] With the continuous development of energy-saving work in residential construction in my country, building energy-saving methods of external wall insulation are becoming more and more popular. However, the plastic foam building insulation materials currently used on a large scale, such as extruded board, polyurethane foam, rubber powder polystyrene particles, phenolic foam board, modified phenolic fireproof insulation board, etc., will emit thick smoke and other harmful gases when burning. In order to prevent fire or control dense smoke, they added flame retardants, curing agents, smoke suppressants, etc., but none of them solved the fundamental problem. The inherent properties of organic substances determine that these materials have relatively poor flame retardan...
