Problems solved by technology

Although the existing conveyor belt patents have considered reducing the rolling resistance, the technologies used have their limitations. The patented formula mainly uses the main rubber and butadiene rubber, and uses the white carbon black / silane system to reduce the rolling resistance of the rubber. Although It has a significant effect in reducing the rolling resistance, but at the same time it leads to a significant decline in the tear resistance of the rubber, which brings hidden dangers to the operation of the conveyor belt.

Abstract

The invention relates to anti-tear conveyer belt covering rubber with low rolling resistance and a preparation method thereof. The formula of the covering rubber comprises the following components in parts by weight: 100 parts of raw rubber systems, 4-8 parts of activating systems, 38-55 parts of reinforcing agents, 2-5 parts of plasticizers, 1-3 parts of fibers, 3-9 parts of anti-aging systems, 1-3 parts of coupling agents and 3-7 parts of vulcanization systems. These components can be prepared into the anti-tear conveyer belt covering rubber with low rolling resistance by the procedures of plastifying, banburying, milling and vulcanizing. On the basis that main body rubber is natural rubber and adopts butadiene rubber, the reinforcing system is subjected to bridging action by adopting an aramid short fiber, the rolling resistance and dynamic heating of the covering rubber are obviously reduced, and meanwhile, the rubber has high tearing resistance, wear-resisting property and anti-fatigue performance.

Description

technical field [0001] The invention relates to a tear-resistant low-rolling resistance conveyor belt covering glue and a preparation method thereof, belonging to the technical field of conveyor belts. Background technique [0002] As a key tool for material transportation in important industries such as coal, mines, docks, building materials, and electric power, conveyor belts have the advantages of large transportation volume and high transportation efficiency. However, because the conveyor belt is subjected to various resistances during operation, it also causes a lot of energy loss form a large waste. After long-term research and analysis of the conveyor belt industry, the most important resistance encountered during operation is the deformation and rolling resistance of the conveyor belt, which accounts for about 60% of the total energy loss. During normal operation, the cover rubber under the conveyor belt will deform due to the force on the contact surface of the idl...
