Abstract

The invention discloses chlorinated polyethylene rubber composite material for a food conveying belt, which comprises the following raw materials in part by weight: 80 to 120 parts of chlorinated polyethylene rubber, 5 to 15 parts of magnesium oxide, 15 to 30 parts of white carbon black, 0.5 to 3 parts of silane coupling agent, 10 to 50 parts of super-fine calcium carbonate, 1 to 5 parts of titanium dioxide, 10 to 20 parts of plasticizer, 5 to 15 parts of white oil, 2 to 10 parts of organic peroxide vulcanizing agent, 1.5 to 3.0 parts of vulcanizing agent and 1 to 10 parts of rubber and plastic deodorant. The mechanical property of the food conveying belt can completely meet the requirements of GB / T 23677-2009, the food conveying belt also has the characteristics of non-toxicity, tastelessness and innocuity, and all hygienic indexes meet the requirements of GB 9685-2008. The material is low in production cost and easy to popularize, and broadens the application range of chlorinated polyethylene rubber.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a chlorinated polyethylene rubber composite material used for food conveyor belts. Background technique [0002] The food conveyor belt is made of non-toxic and harmless materials, non-toxic, no peculiar smell, smooth surface, suitable for transporting food, food raw materials and tobacco and other substances. [0003] Food conveyor belts are made of natural / styrene-butadiene rubber, polyvinyl chloride (PVC), NBR / PVC alloy, polyurethane rubber, polyethylene, polypropylene, PP, nylon, PA, etc., and there are corresponding special ones according to specific food requirements. conveyor. In addition to the characteristics of ordinary conveyor belts, such as high tensile strength, good flexibility, thinness and toughness, food conveyor belts should also have the characteristics of oil resistance, non-toxic hygiene, and easy cleaning. [0004] Now the main material of non-toxic food c...
