Description

technical field [0001] The invention relates to the technical field of waterproof and thermal insulation materials, in particular to a flame-retardant waterproof and thermal insulation material and a preparation method thereof. Background technique [0002] The thermal insulation material industry in foreign countries has a long history, and thermal insulation materials for building energy conservation account for the vast majority. For example, since 1987, building thermal insulation materials in the United States have accounted for about 80% of all thermal insulation materials, and more than 80% of rock wool products in Western European countries such as Sweden and Finland For building energy saving. There are relatively few thermal insulation materials used for building energy conservation in my country. At present, the state is promulgating relevant policies to vigorously promote building energy conservation, which will greatly promote the application of thermal insulat...

Problems solved by technology

However, the commercially available inorganic thermal insulation materials generally have the problem of large thermal conductivity, which leads to a large amount of energy consumption.

[0004] On the other hand, the thermal insulation materials circulating in the market today are not perfect in performance, poor in fire resistance, require adhesives, troublesome in construction, relatively low in strength and firmness, consume a lot of resources, and their structures have yet to be optimized.

For example (polystyrene foam board, foamed polyurethane) has low water absorption and thermal conductivity, but it is not fireproof; inorganic thermal insulation materials with cement as binder, (such as foam cement material, cement-based perlite material, cement-based polystyrene particle putty) have high water absorption and thermal conductivity, and the energy-saving effect is not good; the insulation board produced by other inorganic materials (such as foam glass, floating beads) has complicated manufacturing process, high brittleness, difficult construction and high cost
