Problems solved by technology

[0003] The structure of the domestic conveyor belt is basically cover glue, glue and canvas. The use of glue between the cover glue and the cloth layer is mainly to bond the canvas and the cover glue. The general thickness is 0.8-1.5mm. Although compared with the cover glue The amount of glue used is relatively small, but the total amount of glue used in the thousands of meters of conveyor belt is very large. If the use of glue is omitted, the production cost of the conveyor belt will be saved

Abstract

The invention relates to a chlorosulfonated polyethylene coating adhesive cement and a preparation method thereof and belongs to the technical field of textiles. Chlorosulfonated polyethylene rubber is added to an internal mixer, then a reinforcing filler, maleic anhydride polybutadiene, epoxy resin, an anti-aging agent and a plasticizer are added, and standing is performed to obtain a rubber compound after mixing; a vulcanization accelerator, an imidazole epoxy hardener, sulfur and N-N'-m-phenylenedimaleimide are added to the rubber compound to obtain the masterbatch of the coating adhesive cement; the masterbatch is dissolved in a solvent to obtain the coating adhesive cement. The prepared chlorosulfonated polyethylene coating adhesive cement can make impregnation canvases directly adhered with a conveying belt coating adhere without a bonding compound, convenience is brought to manufacturing and production of conveying belts, and the manufacturing costs of the conveying belts are saved to some degree.

Description

Technical field [0001] The invention relates to a chlorosulfonated polyethylene coating glue slurry and a preparation method thereof. The natural rubber, nitrile butyronitrile, styrene-butadiene and ethylene propylene diene rubber of a sulfur vulcanization system are used for bonding, and can also be vulcanized with peroxides. Ethylene-propylene rubber bonding belongs to the field of textile technology. Background technique [0002] Rubber conveyor belts often use aramid, nylon, and polyester canvas as the skeleton material. These canvases are often dipped in RFL (RF: condensation resin of formaldehyde and resorcinol and L: dipping solution of butyl pyridine latex). The surface of the canvas forms a dipping layer with rubber characteristics. Although RFL dipped canvas can be bonded with natural, nitrile, styrene-butadiene, EPDM and other adhesives of sulfur vulcanization system, but the adhesive strength is not high, and the use of different adhesives is suitable for conveyor be...
