Abstract

The invention belongs to the technical field of conveyor belts and particularly discloses a super wear-resistant rubber-plastic conveyer belt. The technical scheme for forming the conveyor belt is as follows: plasticating natural rubber, butadiene rubber, high styrene, high abrasion furnace black, 40# engine oil, an antiager D, antiager A, antiager 4010NA, zinc oxide, stearic acid, an accelerator NOBS and 2.0-2.5 parts by weight of sulphur powder; curing, banburying, performing open mixing, and vulcanizing to produce the super wear-resistant rubber-plastic conveyer belt. The conveyer belt has the advantages of good wear resistance and low temperature performance; and tests prove that the wear loss of the conveyer belt is no more than 120mm<3>, the tensile strength is more than 21MPa, and the elongation rate is more than 440%.

Description

Technical field [0001] The invention relates to the technical field of conveyor belts, and specifically discloses a super wear-resistant rubber-plastic conveyor belt. Background technique [0002] The rubber conveyor belt is composed of a middle core layer and a cover film layer covering both sides of it. It is mainly used for short-distance transportation of grain and sand. At present, the cover film layer covering both sides of the conveyor belt used is made of ordinary natural rubber and regenerated rubber, and is equipped with stearic acid, pine gum oil, antioxidant, zinc oxide, reinforcing carbon black, etc. It is prepared by mixing, unloading and vulcanizing processes. However, the rubber conveyor belt composed of a cover film layer made of natural rubber and reclaimed rubber and other materials covering both sides of the middle core layer is very easy to cause the inner core to be intact and the outer rubber working surface due to the poor wear resistance of the cover fil...
