Composite multipurpose detachable thermal insulation block and manufacturing method thereof

Abstract

The invention provides a composite multipurpose detachable heat preservation block and a manufacturing method. The heat preservation block is mainly combined by a heat preservation base material in the middle and alkali-free glass fiber cloth, wherein the alkali-free glass fiber cloth is laid on the upper side and the lower side of the heat preservation base material. The heat preservation base material is formed by mixing raw materials of alkali-free long glass fibers and aluminum silicate wool according to a conventional ratio, alkali-free short glass fibers and high-temperature-resistant glue are added in the formed mixed materials through a needling processing technology to form the blocky or strip-shaped heat preservation base material in which the long fibers and the short fibers are mixed and mutually connected, wherein the proportion of the quantity of the alkali-free short glass fibers in the total quantity of the mixed materials is 20-30%, and the proportion of the high-temperature resistant glue in the total quantity of the mixed materials is 5-10%. The manufacturing method includes the following steps that (1) material selecting and forming are conducted, the raw materials of the alkali-free long glass fibers and the alkali-free glass fiber cloth are selected, mixed and formed, then, the alkali-free short glass fibers are added in the mixed and formed mixed materials through the conventional needling processing technology, the high-temperature-resistant glue is sprayed at the same time, and then the blocky or strip-shaped heat preservation base material is manufactured; (2) upper and lower compositing is conducted, namely the alkali-free glass fiber cloth is laid on the upper side and the lower side of the heat preservation base material respectively and fixed on the surface of the heat preservation base material. The composite multipurpose detachable heat preservation block has the advantages of being simple in manufacturing process, low in cost, good in strength and capable of being reused.

Description

technical field [0001] The invention relates to a method for manufacturing a composite multipurpose detachable thermal insulation block, which belongs to the technical field of thermal insulation material manufacturing. Background technique [0002] As a conventional insulation material, needled felt is commonly used, but when needled felt alone is used as an insulation layer, it can only be used once. The reason is that the needle-punched felt is composed of fibers that are not connected, so after disassembly, it becomes a kind of garbage discharge, which seriously affects energy saving and emission reduction. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a composite multi-purpose detachable thermal insulation block with simple manufacturing process, low cost, good strength and reusability and a manufacturing method. [0004] The purpose of the present invention is achieved through ...

AI Technical Summary

Problems solved by technology

[0002] As a conventional insulation material, the use of needle-punched felt is relatively common, but when needle-punched felt is used alone as an insulation layer, it can only be used once, and once it is removed from the insulation equipment or pipeline, it will become broken or broken , the reason is that the fibers of the needle felt are not connected, so after disassembly, it becomes a kind of garbage discharge, which seriously affects energy saving and emission reduction
