Novel wall body heat insulation and heat preservation material

Abstract

The invention relates to a novel wall body heat insulation and heat preservation material, which is prepared from the following ingredients in parts by weight: 22 to 25 parts of bentonite, 100 to 150parts of enveloped expanded perlite, 30 to 100 parts of floating beads, 21 to 32 parts of talcum powder, 54 to 66 parts of cement, 11 to 14 parts of quartzite, 3 to 15 parts of penetrating agents, 4 to 6 parts of powdery lime, 3 to 15 parts of water repellents, 5 to 7 parts of polyacrylamide, 3 to 15 parts of bonding agents, 8 to 13 parts of asbestos, 3 to 15 parts of excitants, 3 to 5 parts of glue powder, 2 to 4 parts of aluminum sulfate, 2 to 5 parts of sodium silicate, 4 to 6 parts of rapid T, 4 to 6 parts of water repellents and 4 to 8 parts of inorganic bonding agents. The novel wall body heat insulation and heat preservation material has the advantages that the expanded perlite is enveloped; the advantages of fire resistance, heat insulation, duration and corrosion resistance of theexpanded perlite are fully utilized; the defect that the expanded perlite can easily absorb water to expand is overcome. Therefore compared with a traditional wall body heat preservation material, the novel wall body heat preservation material has the advantages that the heat preservation performance is better and is more durable; the national fireproof grade A requirement is met.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel wall heat insulation material. Background technique [0002] With the rapid development of industry and economic development, the world's demand for energy is also increasing. Among the increasing total energy consumption, building energy consumption is particularly large, accounting for about 11-25% of the total energy consumption. %, a lot of data and experiments have shown that the fastest and most effective way is to use thermal insulation and energy-saving materials. [0003] Now at home and abroad, there are many types of insulation materials. According to the classification of materials, thermal insulation materials can be divided into three categories: metal thermal insulation materials, organic thermal insulation materials, and inorganic thermal insulation materials. [0004] Metal insulation materials, but the supply of this material is very small and the pri...

AI Technical Summary

Problems solved by technology

However, the traditional expanded perlite is a honeycomb structure material, and there are many holes and cracks on its surface and inside. The defect of high compression ratio during processing will reduce the light weight and thermal insulation effect of expanded perlite products. According to the requirements of thermal insulation materials, the material needs to have a certain strength

[0007] Another fatal disadvantage of perlite is that it is a highly water-absorbing substance, which is due to the porous structure of expanded perlite, and it is a result of open pores, and is absorbent, allowing air and water to come in and out freely. After soaking in water for 25 hours, its water absorption rate returns to about 5 times its own weight. This shortcoming will greatly affect the thermal insulation performance and long-term applicability of expanded perlite products, and will also increase the drying cost of expanded perlite products.
