Problems solved by technology

[0002] There are many insulation materials used for pipelines, equipment, and walls, but some still have high thermal conductivity, poor sealing, large leakage, etc., especially when used for some special-shaped equipment and pipelines. The adhesion of the material is not enough, it is easy to fall off, and the insulation effect is not good enough

Abstract

The composite heat insulating material is fibrous thick paste produced with aluminum silicate fiber 10-18 weight portions, pearlite 12-16 weight portions, asbestos fiber 8-12 weight portions, bentonite 10-15 weight portions, permeating agent 1-3 weight portions and proper amount of clear water. The present invention has the advantages of low heat conducting coefficient, high heat insulating performance, no crack, high sealing performance and less falling, and is especially suitable for use in pipeline, apparatus, furnace and kiln in complicated shape.

Description

technical field [0001] The invention belongs to a composite thermal insulation material. Background technique [0002] There are many insulation materials used for pipelines, equipment, and walls, but some still have high thermal conductivity, poor sealing, large leakage, etc., especially when used for some special-shaped equipment and pipelines. The adhesion of the material is not enough, it is easy to fall off, and the insulation effect is not good enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite thermal insulation material with low thermal conductivity, not easy to crack, good sealing performance and not easy to fall off. [0004] The technical solution for solving the above problems is: the present invention is a fiber-thick paste made of the following weight ratio raw materials: [0005] Aluminum silicate fiber: 10-18 parts Perlite: 12-16 parts Asbestos fiber: 8-12 parts [0006] Benton...
