Abstract

The invention relates to a fireproof external wall heat insulation material comprising the following components in parts by weight: 550-650 parts of sulphate aluminum cement, 280-350 parts of coal ash, 240-300 parts of water, 1-2.5 parts of potassium permanganate, 10-25 parts of calcium stearate, 5-10 parts of polypropylene fiber, 200-220 parts of nanometer cement additives, 25-35 parts of glass bead particles and 30-54 parts of hydrogen peroxide. The heat insulation material disclosed by the invention is simple in formula as well as wide and has easily available raw material source; the preparation method is simple and easy to operate; and the heat insulation material is uniform in foaming, low in product density and heat conductivity coefficient, capable of reaching the energy-saving standard and meeting the A-grade fireproof requirement and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and relates to thermal insulation materials, in particular to thermal insulation materials for fireproof exterior walls. Background technique [0002] With the advancement of science and technology and the improvement of living standards year by year, thermal insulation materials have become one of the indispensable supplies in people's production and life. In the prior art, a good formula that is both fireproof, light and low in thermal conductivity has not been found. Although many inorganic thermal insulation materials on the market are fireproof, they have high density, high thermal conductivity, and poor water resistance, which are far from energy-saving indicators. Although organic thermal insulation boards have low density, good processability, and good thermal insulation effects, the products It is flammable and has low safety performance. Inorganic materials such a...
