Thermal insulation material

Abstract

The invention discloses a thermal insulation material which comprises the following raw materials in parts by mass: 100 parts of a solid mixture and 100-150 parts of a magnesium chloride solution, wherein the solid mixture comprises the following components in percentage by mass: 10-90% of magnesium oxide powder, 5-89% of packing and 0.8-10% of a foaming agent; and the packing can be any one of fly ash, dolomite powder, calcium carbonate powder, gypsum powder, perlite, red mud, lake sludge, river sand and coal gangue. In the thermal insulation material, the foaming agent is prepared by mixing peroxides, a sizing agent and a foam stabilizer; when used in the preparation of the thermal insulation material, the foaming agent is high in foaming speed and uniform in foaming; and the thermal insulation material disclosed by the invention not only can effectively reduce the bearing of a building, but also has good thermal insulation properties; therefore, the thermal insulation material can be widely applied to building blocks, thermal equipment and various ventilating pipes and industrial pipes in industrial and civil buildings.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a thermal insulation material. Background technique [0002] Inorganic thermal insulation materials have the characteristics of high strength, good fire and flame retardant safety, good thermal performance, convenient construction, high stability, green environmental protection and pollution-free, etc., and are increasingly favored by customers. Among many inorganic thermal insulation materials, magnesium cement material is a kind of thermal insulation material with excellent performance; ordinary magnesium cement material has high strength, fire resistance, anti-corrosion and other properties, but its bulk density is larger than other thermal insulation materials, which restricts ordinary magnesium cement.

Among many inorganic thermal insulation materials, magnesium cement material is a kind of thermal insulation material with excellent performance; ordinary magnesium cement material has high strength, fire resistance, anti-corrosion and other properties, but its bulk density is larger than other thermal insulation materials, which restricts ordinary magnesium cement. The development of cement as thermal insulation material, so by using ordinary magnesium cement material as matrix, adding foaming agent to it to produce lightweight magnesium cement material, thereby reducing its bulk density has become a development trend of inorganic thermal insulation materials; but the existing development Foam technology has slow foaming speed and uneven foaming, which is not suitable for large-scale industrial production, and also affects the thermal insulation performance of the product
