Abstract

The invention discloses covering rubber which is characterized by being prepared by the following formula: 15-20phr of natural rubber, 80-85phr of butadiene rubber and butadiene styrene rubber, 5phr of zinc oxide, 2-3phr of stearic acid, 45-46phr of reinforcing filler, 35-45phr of a fire retardant, 4-6phr of a plasticizer, 4phr of an anti-aging agent, 2phr of a vulcanizing accelerator and 3phr of sulphur. The invention also discloses the usage of the covering rubber in the production of a steel wire rope conveyer belt. The covering rubber not only has good flame retardant property and bonding force, but also has excellent low temperature resistance and cold resistance; after the covering rubber is used for producing the steel wire rope conveyer belt, the steel wire rope conveyer belt is not hardened, does not slide and crack, is not broken and the like due to the very low temperature in winter when being used in the severe cold low-temperature area.

Description

technical field [0001] The invention relates to the field of materials for conveyor belts, in particular to a covering glue and its application. Background technique [0002] At present, almost without exception, the new large-scale and super-large mines, modern mine ports, open-pit coal mines, and iron ore conveying systems in China all use high-strength flame-retardant steel wire rope conveyor belts as the conveying method for solid materials. However, in the Northeast of my country and even in the severe cold of Russia, the general-purpose flame-retardant conveyor belts currently used cannot adapt to the climatic conditions there. In winter, when the ambient temperature drops below -30°C, the tape will become hard and slippery, and the surface of the conveyor belt covering rubber will crack. In severe cases, the tape will even break and break. It has greatly affected the smooth progress of the production of the conveyor belt manufacturer. Therefore, there is an urgent n...
