Problems solved by technology

Ordinary steel cord conveyor belts have disadvantages such as poor impact resistance, lack of resilience, and easy tearing in the longitudinal direction during transportation and use, and if they are not found in time or handled improperly during use, the entire belt will be damaged. The scrapping of the belt body not only affects the production efficiency, but also causes serious economic losses to the manufacturer and the user

Abstract

The invention relates to cover rubber for an impact and tear resisting steel cord conveyor belt. The cover rubber is prepared from, by weight, 45-60 parts of smoked sheet rubber, 20-30 parts of butadiene rubber, 15-20 parts of high impact polystyrene, 1.5-3 parts of sulphur, 15-20 parts of active agent, 3.5-5 parts of accelerant, 10-15 parts of amorphous silicon dioxide, 5-8 parts of polyurethane resin, 45-60 parts of medium or super wear-resisting carbon black N220, 2.5-3 parts of antiager, 3-4 parts of microcrystalline wax, 2-5 parts of C5 petroleum resin and 10-15 parts of rubber tear resisting agent. The problem of ordinary conveyor belts or ordinary tear resisting conveyor belts that tearing and damage are caused easily in use is solved. By improving the influence of initial mixing temperature, rubber discharging temperature and internal mixer rotor speed on the dispersity of filler in the cover rubber during mixing, comprehensive mechanical properties, including tensile strength, tearing strength and impact resistance, of the cover rubber are improved.

Description

technical field [0001] The invention belongs to the technical field of conveyor belts, and in particular relates to a covering glue for an impact-resistant and tear-resistant steel cord conveyor belt and a preparation method thereof. Background technique [0002] With the development of mining, cement, metallurgical and chemical industries, as well as the rapid rise of my country's docks and ports, the belt conveyor is now developing in the direction of long distance, large capacity, high speed, high efficiency, and multi-function. The operating conditions of the conveyor belt Increasingly demanding, put forward higher requirements for its performance. Ordinary steel cord conveyor belts have disadvantages such as poor impact resistance, lack of resilience, and easy tearing in the longitudinal direction during transportation and use, and if they are not found in time or handled improperly during use, the entire belt will be damaged. The scrapping of the belt body not only aff...
