Abstract

The invention discloses a room temperature vulcanized rubber strip for automatic repairing of conveyor belts and a preparation method thereof. 20-50 parts of base functionalized solution polystyrene-butadiene rubber, 2-5 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 5 parts of anti-aging agent, 4-10 parts of alkyl phenolic tackifying resin, 30 parts of high wear-resistant carbon black ‑45 parts, 5‑10 parts of bisphenol A, 1.0‑3.0 parts of sulfur; rubber strip 2 includes the following raw materials in parts by weight: 70‑100 parts of end-group functionalized solution-polymerized styrene-butadiene rubber, 10-parts of carboxyl-terminated liquid nitrile rubber 30 parts, 30-45 parts of high wear-resistant carbon black, 1.0-3.0 parts of zinc isopropyl xanthate, and 0.3-1.0 parts of phthalic anhydride. Inconvenient, sticky and poor repair quality technical issues.

Description

technical field [0001] The invention relates to the technical field of conveyor belt rubber strips, in particular to a room temperature vulcanized rubber strip for automatic repair of conveyor belts and a preparation method thereof. Background technique [0002] Conveyor belts are mainly used in mines, ports, steel plants, power plants, construction, cement, coal mines and other industries, especially in iron ore, copper mines, coal mines and ports. It is easy to cause abnormal surface damage or scratches on the tape during its service life. If it is not repaired in time, the tape will be completely damaged, lose its use value, and cause tape loss to customers. Therefore, research on tape repair technology has always been the priority of conveyor belt manufacturers. Focus on work, high-quality repairs can completely restore more than 80% of the performance of the tape, creating significant economic benefits for customers, and also promoting the maximum use of resources. The...
