Rare earth heat-preserving material

Abstract

The invention relates to a rare earth heat-preserving material. The rare earth heat-preserving material is characterized by being prepared by compounding the following raw materials in percentage by weight: 35 to 41 percent of pearlite, 5 to 10 percent of fly ash, 5 to 6 percent of aluminium silicate cellucotton, 5 to 6 percent of rock wool, 15 to 17 percent of asbestos wool, 15 to 17 percent of bentonite, 3 to 4 percent of polyacrylamide, 5 to 6 percent of penetrating agent and 0.03 to 0.3 percent of rare earth additive. The rare earth heat-preserving material has the advantages of high temperature resistance, high corrosion resistance, high sound insulation, high ageing resistance, high cracking resistance, low thermal conductivity coefficient and light dry unit weight, wherein the highest temperature is 1,000 DEG C; the lowest temperature is -30 DEG C; and particularly, the fire resistance reaches A1 level.

Description

1. Technical field [0001] The invention relates to a rare earth thermal insulation material, which belongs to the field of building materials, in particular to the field of thermal insulation coatings. 2. Background technology: [0002] my country's thermal insulation coatings such as: silicate, magnesium silicate and other thermal insulation materials have made great progress in recent years, but there are still some unsatisfactory places. The defects are: 1. The highest thermal insulation temperature is mostly within 800 ° C. When used at high temperature, the coating will be carbonized, which will affect the insulation life and effect; 2. Silicate and magnesium silicate insulation coatings have heavy dry capacity and high thermal conductivity. In recent years, buildings are all energy-saving and thermal insulation houses. In terms of building energy conservation, my country is still exploring. Although polystyrene boards are the main product of building energy conservation...
