Enhanced insulating ceramic composite material as well as use thereof

Abstract

The invention belongs to an enhanced insulating ceramic composite material as well as use thereof. The enhanced insulating ceramic composite material comprises raw materials in parts by weight as follows: 10-20 parts of wollastonite, 2-16 parts of attapulgite, 2-16 parts of aluminum silicate wool, 2-16 parts of brucite, 1-8 parts of sodium silicate pentahydrate, 20-30 parts of sepiolite powder, 1-4 parts of diatomaceous earth, 1-8 parts of glass beads, 1-4 parts of pumice, 1-4 parts of zeolite, 1-10 parts of coal ash, 20-40 parts of perlite, 0-5 parts of replenisher and 0-1 part of water-proofing agent. The enhanced insulating ceramic composite material provided by the invention is used between a heating element to be insulated and a hard silicate product to greatly increase the insulating effect and reduce the thickness of the insulating layer. The enhanced insulating ceramic composite material has the advantages of good insulating and thermal blocking effect, low construction and insulating costs, no damage to a human body, no environmental pollution, long service life and energy conservation and environment friendliness.

Description

[0001] technical field [0002] The invention belongs to a reinforced thermal insulation ceramic composite material and its application. Background technique [0003] At present, there are many types of traditional thermal insulation materials used for industrial thermal insulation and building thermal insulation in my country, mainly including hard silicate products, foam plastics and cotton felt thermal insulation materials. Among these materials, foamed plastics and cotton felt insulation materials are mostly used in the field of civil daily necessities, but not in the industrial field. The insulation in the industrial field is mostly used for the outer layer of high-temperature pipes, boilers or equipment. Hard silicic acid Salt products are suitable for heat preservation of the above-mentioned heating elements in the industrial field. However, the thermal conductivity of hard silicate products increases rapidly in the high-temperature area of ​​the above-mentioned h...

AI Technical Summary

Problems solved by technology

However, the thermal conductivity of hard silicate products increases rapidly in the high-temperature area of ​​the above-mentioned heating element shell, so the heat preservation effect on high-temperature heating elements is poor, and the heat loss is high. In order to increase the heat preservation effect, it is often necessary to increase the heat preservation effect of hard silicate products. However, the increase in the thickness of the insulation layer will increase the heavy load on the heating element, which will easily cause damage to high-temperature pipes, boilers or equipment, and will also greatly increase the construction and insulation costs, which is not conducive to energy saving and emission reduction.
