A method for manufacturing a multi-cavity ceramic composite thermal insulation material

Abstract

The invention proposes a method for manufacturing a multi-cavity ceramic composite thermal insulation material. Pour the prepared slurry A into the vacuum water absorption mold for dehydration treatment. After the water drops, spread the prepared slurry B on the surface and continue dehydration to make the product form a thermal insulation composite layer. After drying, it will be used as a felt-like thermal insulation package material used. The thermal insulation felt sheet made by the method of the present invention uses the combination of existing thermal insulation materials, utilizes the different thermal conductivity coefficients of different materials at different temperature sections to exert their respective advantages, forms a composite structure, and produces composite properties , not only has many advantages over traditional fiber materials in terms of structural strength, toughness and thermal insulation performance, especially it is divided into upper and lower layers. The upper layer has high strength and can withstand general impact, while the lower layer has good thermal insulation properties, making the material have excellent performance . It is suitable for application as a ceramic multi-cavity composite thermal insulation material.

Description

Technical field [0001] The invention belongs to the field of insulation materials, and is a method for producing a multi-chamber ceramic composite heat insulating material. The product is a blanket whose ceramic fibers and ceramic particles, which is elastic, and large area is applied to insulation insulation projects in various fields. Background technique [0002] With the penetration of industrial development, the requirements for environmental protection are increasing, energy-saving and environmentally friendly, I have a high voice. However, in the field of insulation in my country, in decades, we have used the materials of mineralns, which is basically full fiber structure, low thermal resistance at high temperatures, high temperature bridge, long-term variable rate And more than the insulated body, enabling the insulation engineering as dummy, and the energy loss increases. According to these, we invented a multi-chamber ceramic compound composite insulating material. This...

However, in the field of thermal insulation in my country, for decades, we have mostly used mineral wool materials, which are basically full-fiber structures, have small thermal resistance at high temperatures, increase thermal bridges, and have high deformation rates after long-term use. , and most of them are separated from the body to be insulated, making the insulation project useless and increasing energy loss
