Abstract

The invention relates to a core adhesive for a steel wire rope core conveying belt, in particular to a core adhesive for a flame-retardant steel wire rope core conveying belt and a preparation method thereof. The core adhesive for the flame-retardant steel wire rope core conveying belt is prepared by plastifying, compounding, cooking, rolling, molding and vulcanizing a rubber system, a vulcanizing system, a tackifying system, a reinforcing system, a plastifying system, a softening system and a flame-retardant system. The core adhesive for the flame-retardant steel wire rope core conveying belt disclosed by the invention can meet various physical and chemical index requirements, and has high steel wire rope bonding capability and excellent flame retardance.

Description

technical field [0001] The invention relates to a core glue for a steel cord conveyor belt, in particular to a core glue for a flame-retardant steel cord conveyor belt and a preparation method thereof. Background technique [0002] With the expansion of the scale of major coal mine enterprises and the increase of coal mine output, the market demand for high-grade flame-retardant steel cord conveyor belts will be reflected. However, the flame-retardant steel cord conveyor belts commonly used in the market currently have the highest strength level of ST6300, and the steel cord conveyor belts above ST7500 have not yet been mass-produced and used. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a core rubber with flame-retardant effect for flame-retardant steel cord conveyor belts. [0004] According to the technical scheme provided by the present invention, a kind of core rubber for flame-r...
