▎ 摘　　要

NOVELTY - Preparing multi-layer rubber conveying belt comprises (a) preparing rubber base layer: mixing and extruding fluorinated silicone rubber, nitrile rubber, nano tin dioxide powder, graphene powder, compounding agent, adhesive and accelerant, (b) primarily preparing the fabric reinforcing layer, cleaning the waste fabric, placing into a crusher to crush, crushing and placing into a mixer, adding bamboo charcoal powder, adhesive, thickener, natural latex, water, and Neoprene (Chloroprene rubber) into the mixer, fully mixing, (c) placing the material after mixing into the extruding machine to extrude and form and (d) uniformly coating the rubber base layer surface by glue, compounding the fabric reinforcing layer with the rubber base layer by hot pressing, so that two layers of rubber base layer can interval a layer of fabric reinforcing layer, finishing the preparation of multi-layer rubber conveying belt. USE - The method is useful for preparing multi-layer rubber conveying belt. ADVANTAGE - The method: enables adding nano-tin dioxide powder with enhanced and heat-resistant effect, fluorinated silicone rubber, graphene powder and nitrile rubber, which can improve the strength and heat resistance of the whole rubber conveying belt and comprehensive performance and is more environmentally-friendly. DETAILED DESCRIPTION - Preparing multi-layer rubber conveying belt comprises (a) preparing rubber base layer: mixing and extruding 8-13 pts. wt. fluorinated silicone rubber, 8-12 pts. wt. nitrile rubber, 8-15 pts. wt. nano tin dioxide powder, 5-8 pts. wt. graphene powder, 1-1.5 pts. wt. compounding agent, 8-13 pts. wt. adhesive and 5-8 pts. wt. accelerant, (b) primarily preparing the fabric reinforcing layer, cleaning the waste fabric, placing into a crusher to crush, crushing and placing into a mixer, adding 8-15 pts. wt. bamboo charcoal powder, 5-10 pts. wt. adhesive, 6-12 pts. wt. thickener, 50-80 pts. wt. natural latex, 80-100 pts. wt. water, and 30-50 pts. wt. Neoprene (Chloroprene rubber) into the mixer, fully mixing, (c) placing the material after mixing into the extruding machine to extrude and form and (d) uniformly coating the rubber base layer surface by glue, compounding the fabric reinforcing layer with the rubber base layer by hot pressing, so that two layers of rubber base layer can interval a layer of fabric reinforcing layer, finishing the preparation of multi-layer rubber conveying belt. An INDEPENDENT CLAIM is also included for a preparation device of rubber conveying belt comprises a through type hot pressing compound machine (1) set on a feeding and discharging port (2). The top part surface the through-type hot pressing compound machine is rotatably mounted with an operation box (3). Two sides surface the operation box are provided with a handle (4). DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the rubber conveying belt preparation device. Through type hot pressing compound machine (1) Feeding and discharging port (2) Operation box (3) Handle (4)
