Abstract

The invention relates to a fireproofing and heat-insulation glass fiber material and a preparation method thereof and belongs to the technical field of glass fibers. The fireproofing and heat-insulation glass fiber material is composed of a glass fiber wool layer and a curing layer coating same. The glass fiber wool layer consists of medium-alkaline glass fiber wool being 0.6-3.5 [mu]m in diameterand the curing layer includes a heat-resistant adhesive and aerogel. The material is light in weight and high in strength, and has great fireproofing and heat-insulation property. The material is 0.2-9.3 mm in thickness, 40-1200 g / m2 in basis weight, and 0.02-0.035 W / m*K in heat conductivity coefficient. Meanwhile, the preparation method is simple and is low in equipment demand, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of glass fibers, and in particular relates to a fire-proof and heat-insulating glass fiber material and a preparation method thereof. Background technique [0002] At present, in my country, traditional thermal insulation materials such as rock wool, glass wool, and expanded perlite will not be able to achieve energy saving due to their high density, poor thermal insulation performance, large loss, high moisture absorption, poor seismic performance and environmental protection performance. standard. In addition, building insulation materials such as asbestos and glass wool itself contain a large amount of harmful substances, which cannot meet human health requirements. [0003] With the improvement of people's living standards, the requirements for maintaining a suitable temperature in residential and working environments are getting higher and higher. Therefore, the heating and air conditioning of houses a...
