a wall insulation material

Abstract

The invention discloses a novel wall body heat insulation material in the field of construction materials. The novel wall body heat insulation material comprises the following components in parts by weight: 100-150 parts of expanded perlite, 30-100 parts of floating beads, 30-50 parts of cement, 3-15 parts of a penetrating agent, 3-15 parts of a water repellent, 3-15 parts of a binding agent and 3-15 parts of an exciting agent. According to the novel wall body heat insulation material, through enveloping the expanded perlite, the advantages of fire resistance, heat preservation, permanence and corrosion resistance of the expanded perlite are used fully, and the defects of high probability of water absorption and swelling of the expanded perlite are overcome. Therefore, compared with traditional wall body heat insulation materials, the novel wall body heat insulation material has better and more lasting thermal insulation performance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a wall thermal insulation material. Background technique [0002] With the rapid development of industry and economic development, the world's demand for energy is also increasing. In 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 t...

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.
