Problems solved by technology

However, due to the limitation of the skeleton material itself, this kind of conveyor belt has low strength, small transportation capacity, and relatively short transportation distance.
The core rubber of the canvas heat-resistant conveyor belt is natural system of styrene-butadiene, and the same is true for ordinary normal-temperature steel mesh core rubber. Although the natural styrene-butadiene system has better adhesion at room temperature, once the use temperature exceeds 150 ° C, due to the heat resistance of the rubber itself Poor, resulting in a sharp drop in adhesion to the steel wire, a sharp drop in the amount of glue attached to the steel wire, and loss of use value

Abstract

The invention relates to a preparation method of core glue for a high-temperature resistant steel mesh conveyor belt, comprising the following process steps of: (1) mixing: adding ethylene propylene rubber, chloroprene rubber and carbon black in an internal mixer for mixing; (2) internal mixing by two stage: adding zinc oxide, stearic acid, aging inhibitorn aging inhibitor RD, an accelerator CZ, a binding agent RS, white carbon black, calcium carbonate, cobalt boroacylate and rubber oil in glue stock obtained from internal mixing, carrying out the first-stage internal mixing on the internal mixer and adding insoluble sulfur, the binding agent RA and zinc methacrylate in the obtained glue stock which is stood for 6-8 hours for the second-stage internal mixing; (3) discharging colloid obtained by two-stage internal mixing into an open mill for back mixing; and (4) pressing the colloid subjected to back mixing on an extruder into a sheet and obtaining the core glue. The invention can solve the problem that the core glue is bonded with the steel mesh under the high-temperature condition.

Description

technical field [0001] The invention relates to a preparation method for a core rubber for a high-temperature-resistant steel mesh conveyor belt, in particular to a core rubber for a high-temperature-resistant steel mesh conveyor belt. Background technique [0002] Heat-resistant conveyor belts generally refer to multi-layer rubber cotton canvas (polyester cotton cloth) or polyester canvas covered with high-temperature resistant or heat-resistant rubber, bonded together by high-temperature vulcanization, suitable for conveying hot coke below 175°C, Cement, slag and hot castings, etc. However, due to the limitation of the skeleton material itself, this kind of conveyor belt has low strength, small transportation capacity, and relatively short transportation distance. The core rubber of the canvas heat-resistant conveyor belt is natural system of styrene-butadiene, and the same is true for ordinary normal-temperature steel mesh core rubber. Although the natural styrene-butadi...
