The invention provides a surface adhesive sizing material for an oil tank sealing tape adhesive tape. The surface adhesive sizing material takes nitrile rubber and PVC paste resin as main materials and high abrasion furnace carbon black, light calcium carbonate and dibutyl phthalaten as auxiliary materials, the materials are matched and mixed in parts by weight, and the rubber compound is manufactured through mixing of an internal mixer. The surface adhesive sizing material has high tensile strength, good abrasion resistance and good oil resistance, and is preferably applicable to the requirements of oil tank sealing devices for sealing tape oil resistance and abrasion resistance. The sizing material is high in aging resistance, high in cold resistance and long in service life.
Description
technical field [0001] The invention relates to an oil tank sealing tape, in particular to an oil tank sealing tape adhesive cloth surface rubber material. Background technique [0002] The oil tank sealing belt is the structural main body of the floating roof oil tank sealing device. It is made of oil-resistant and weather-resistant rubber after vulcanization. It has enough flexibility and can fit well with the tank wall. It is mainly used for floating roof oil storage tanks and chemical product storage tanks. It is installed on the edge plate of the floating roof of the storage tank. The sealing tape makes sliding contact with the tank wall as the floating plate rises and falls, and uses the sealing tape (wrapped with sponge or liquid-filled) itself Seal between the elastic and the tank. To reduce and prevent the volatilization of the medium to achieve the purpose of saving. [0003] Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Ni...
