Abstract

The invention provides a flame-retardant self-adhesive for a composite gas isolation board and a preparation method thereof, which solves the problem of the composite gas isolation board in the prior art, where the ordinary waterproof board cannot be fully bonded to the second lining structure, causing the primary lining to be separated from the second lining. The occurrence of water channeling between the structures will cause the technical problem of large-area leakage of the structure. It is prepared from the following raw materials in weight percentage: SIS elastomer 18%-21%; first polyisobutylene 10%-18%; second polyisobutylene 6%-8%; first C5 petroleum resin 25%-30%; The second C5 petroleum resin 5%-12%; flame retardant 10%-20%; polyethylene wax 2%-5%; antioxidant 1%-1.5%; anti-ultraviolet agent 0.5%-1.5%; The sum of weight percentages is 100%. When the present invention is applied to the composite gas isolation board, water channeling between the primary lining and the secondary lining structure is avoided, and large-area leakage of the structure can be avoided.

Description

technical field [0001] The invention relates to a composite gas isolation board, in particular to a flame-retardant self-adhesive adhesive for a composite gas isolation board and a preparation method thereof. Background technique [0002] The anti-gas and waterproof isolation projects of tunnels in my country mainly need to meet gas barrier properties, flame retardancy, antistatic properties and excellent mechanical properties. Most of the gas barrier panels currently in use have poor gas barrier properties, are not antistatic, and are hard Due to the long-term high and low temperature changes in the use environment, there are dimensional changes in the plastic sheet, which leads to gas insulation performance defects; because of the long-term harsh use environment, the material has performance attenuation, and due to the lack of flexibility of the material, It is not easy to fold, which also causes some troubles for road transportation, and has the disadvantage of poor constru...
