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
[0006] 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.

Abstract

The invention discloses a silicate wall insulation material and a preparation method thereof. The silicate wall insulation material is prepared from the following raw materials (by weight): 12-25 parts of expanded perlite, 10-20 parts of water glass, 3-13 parts of a curing agent, 6-18 parts of calcined kaolin, 6-15 parts of fly ash, 13-16 parts of dimethyl siloxane, 5-16 parts of a composite catalyst, 15-25 parts of water, 3-18 parts of polyvinyl alcohol, 8-16 parts of boron fibre and 6-12 parts of sodium silicate. The invention provides a silicate wall insulation material and a preparation method thereof. Through coating of expanded perlite, advantages of expanded perlite such as water resistance, thermal insulation, durability and corrosion resistance are fully utilized, and the defect that expanded perlite is easy to absorb water and swell is reduced. in comparison with a traditional wall insulation material, the prepared silicate wall insulation material has better and more lasting thermal insulation property.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, and in particular relates to a silicate wall thermal insulation material and a preparation method thereof. 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. Metal insulation materials, but the ...
