Silicon-based microcrystal heat-insulating material

Abstract

The invention discloses a silicon-based microcrystal heat-insulating material comprising the following components in percentage by weight: 30.5%-46.5% of silicon-based microcrystal, 43%-55.6% of inorganic gelled materials, 9%-11.8% of crack-resistant additives and 1.37%-2.32% of auxiliary adhesives. The silicon-based microcrystal heat-insulating material has good temperature-resisting performance, low and stable heat conductivity, corrosion resistance, high strength and good construction performance when used for a heat-insulating system, has good flame-retardant effect and can achieve the purpose of having the same service life of concrete or cement plaster according to physical and chemical performance analysis.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a silicon-based microcrystalline thermal insulation material. Background technique [0002] According to the physical and chemical properties of energy-saving insulation materials, they can be divided into organic insulation materials and inorganic insulation materials. The thermal conductivity of commonly used organic thermal insulation materials is relatively easy to reduce, but it has low strength, poor construction performance, poor fire resistance, high temperature produces toxic and harmful substances, poor aging resistance and weather resistance, large rebound during construction, and easy to be eaten by insects and ants. defect. Therefore, the research, development and use of inorganic thermal insulation materials is the direction of energy-saving material technology, environmental protection requirements and market development, and has positive practical significance and...

Problems solved by technology

[0006] However, polyphenylene particles and ordinary expanded perlite are used as lightweight aggregates and other traditional thermal insulation mortars have many defects and deficiencies, such as expanded perlite has a high water absorption rate, is easy to pulverize, and has a large volume loss rate during slurry mixing, which is easy to cause The thermal insulation performance of the product is lowered and hollowed and cracked in the later stage; organic materials such as polystyrene have poor fire resistance, harmful gases generated at high temperatures, low aging resistance and weather resistance, large rebound during construction, and are susceptible to insects and ants; when the temperature When it reaches 80°C, polystyrene begins to decompose and produce toxic and harmful gases; at the same time, most organic materials have poor construction performance, etc.
