Abstract

The invention relates to a high-strength building external wall thermal-insulation material which comprises a thermal-insulation material matrix and a high-strength system, wherein the high-strength system accounts for 11.2-11.4% of the thermal-insulation material matrix. The thermal-insulation material matrix comprises the following components in parts by weight: 32-34 parts of polyethylene resin, 6-8 parts of aluminum oxide, 5-7 parts of magnesium oxide, 3-5 parts of magnesium chloride, 3.5-3.7 parts of polycarbonate, 3-5 parts of glass fiber, 2.5-2.7 parts of butyl rubber and 4.5-4.7 parts of polyethyleneglycol. The thermal-insulation material has the advantages of high strength, favorable thermal-insulation effect, poor hydroscopic property, fire resistance, acid / alkali resistance and aging resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-strength thermal insulation material for building exterior walls. Background technique [0002] At present, energy-saving wall insulation systems are generally divided into two categories: one is composite wall insulation system, which includes exterior wall insulation system, exterior wall interior insulation system, sandwich composite insulation system; the other is self-insulation The system refers to the external wall insulation system that can meet the existing energy-saving requirements with a single wall material. The insulation material is the wall material itself, which is generally used in non-load-bearing walls. Clay solid bricks were the main masonry materials for masonry buildings in my country before building energy conservation was proposed. Now, because of their poor thermal performance, coupled with serious waste of land resources, e...
