Abstract

The invention provides a composite insulation material and an insulation method thereof. The composite insulation material comprises an inner insulation layer, an isolation layer, more than one outer insulation layer and a protective layer arranged in order from inside to outside. The inner insulation layer comprises a transitional layer and a calcium silicate insulating layer arranged in order from inside to outside. The transitional layer is a felt layer and / or a polysilicon fiber layer. The isolation layer comprises a polysilicon fiber layer and a flame-retardant stone mastic asphalt layer arranged in order from inside to outside. The outer insulation layer comprises an aerosol layer and a multi-condensation foam glass layer arranged in order from inside to outside. The composite insulation material is low in cost, small in size and light in weight, has good, lasting insulation effect and is widely applicable.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a composite thermal insulation material and a thermal insulation method. Background technique [0002] There are many equipment and steam heat pipe networks involved in the fields of electric power and chemical industry. At present, traditional insulation materials such as rock wool, aluminum silicate, and glass wool are mainly used for insulation of these equipment and pipelines. However, the insulation effect of these materials is poor, especially The thermal insulation effect shows obvious attenuation with climate change, and the timeliness of thermal insulation is low. Therefore, it is urgent to develop new thermal insulation materials, so as to save costs, reduce heat loss and coal consumption to the greatest extent. [0003] With the increasing shortage of bauxite resources in my country, the use of high-alumina fly ash, coal gangue and other industrial solid wastes to extra...
