Abstract

The invention relates to a static electricity conductive flame retardant rubber for an oil tank sealing strip. The rubber takes butyronitrile rubber as a main raw material, which is mixed with stearic acid, zinc oxide, acetylene carbon black, semi reinforcing carbon black, aluminum hydroxide, decabromodiphenyl ether, antimony trioxide, chlorinated paraffin wax, antiager 4010NA, antiager A, sulfur, accelerant CZ, accelerant TMTM, coumarone and dioctyl phthalate, and the mixture is mixed by an internal rubber mixer, and the rubber is bonded on both sides of a gum dipping framework by a calenderand is subject to the sulfuration, thus the static electricity conductive flame retardant sealing strip is obtained. The surface resistance of the product is less than 3x10<8>Ohm, and the burning performance is no less than FV-1 class, the rubber of the invention meets the requirements of an steel oil tank on the static electricity conduction and the flame retardation of the rubber sealing strip.

Description

A static conduction and flame retardant rubber used for oil tank sealing tape technical field The invention relates to a rubber, in particular to a static-conducting and flame-resistant rubber used for an oil tank sealing belt. Background technique Steel oil tanks have been used for oil storage for more than 100 years, and are still the main oil storage containers in various countries. There is a steel floating roof that can float up and down in the oil tank, and the gap between the floating roof and the tank wall is sealed with a rubber soft sealing device to prevent oil volatilization. During the up and down movement of the floating roof, static electricity is generated due to friction between the rubber soft sealing device and the metal tank wall. The accumulation of static electricity can cause fire or even explosion accidents, seriously affecting the operation safety of the oil tank. Therefore, the rubber sealing tape in the rubber soft sealing device must have stat...
