Fireproof thermal insulation material

Abstract

The invention discloses a fireproof thermal insulation material, comprising an inorganic raw material, an organic raw material and a fiber mixture, wherein the inorganic raw material is prepared from the following components in parts by weight: 21-45 parts of metallic oxide, 13-34 parts of silicon dioxide powder, 15-46 parts of calcium carbonate powder, 22-89 parts of a sulfate mixture, 35-76 parts of a silicate mixture, 17-48 parts of a binding agent and 31-56 parts of a foaming agent; the organic raw material is prepared from the following components in parts by weight: 10-24 parts of phenolic resin powder and 3-16 parts of polyurethane powder; the fiber mixture is prepared from the following components in parts by weight: 35-72 parts of asbestos fiber and 11-17 parts of metal fiber. The fireproof thermal insulation material is reasonable in raw material ratio; the density of the fireproof thermal insulation material is lower than that of a traditional thermal insulation material while strength and heat preservation performance are guaranteed; therefore, the fireproof thermal insulation material is lighter in weight and wider in application scope.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a fireproof thermal insulation material. Background technique [0002] Most of the existing thermal insulation materials have poor thermal insulation performance and high thermal conductivity, and cannot play a good thermal insulation effect in occasions that require thermal insulation. Traditional thermal insulation materials do not have the effect of fire prevention and have a low ignition point. Therefore, in In the process of use, once a fire occurs, the loss will be huge. The density of traditional thermal insulation materials is high, not light enough, and the cohesiveness of the overall material is poor, resulting in insufficient strength of products made of traditional thermal insulation materials. It is easy to fall off, and the scope of use is relatively limited. Contents of the invention [0003] The object of the present invention is to provide a fire-pr...
