Abstract

Disclosed are a rubber composition for a conveyor belt and a conveyor belt which can maintain basic physical properties such as high rupture strength and high wear resistance and can reduce the power consumption to a satisfactory level. The rubber composition comprises a rubber component comprising natural rubber (NR) and polybutadiene rubber (BR), carbon black, silica, a silane coupling agent and diethylene glycol, wherein the ratio between the amount of natural rubber and the amount of polybutadiene rubber (NR / BR) in the rubber component is 80 / 20 to 25 / 75, the content of carbon black is 15 to 35 parts by mass based on 100 parts by mass of the rubber component, the content of silica is 5 to 25 parts by mass based on 100 parts by mass or the rubber component, the content of the silane coupling agent is 0.5 to 3 parts by mass based on 100 parts by mass of the rubber component, and the content of diethylene glycol is 0.5 to 4.5 parts by mass based on 100 parts by mass of the rubber component.

Description

technical field [0001] The present invention relates to rubber compositions for conveyor belts and conveyor belts. Background technique [0002] Conveyor belts are often used to transport materials. However, due to increases in transport volume, improvements in transport efficiency, and other factors, there is a need for larger size and higher strength conveyor belts. More recently, conveyor belts with a total length of thousands of kilometers have appeared. As a result, equipment costs and energy consumption are also rising, leading to the desire for low cost, low energy consumption belt conveyor systems. In particular, ways of reducing the cost and energy consumption of conveyor belts are being investigated by improving the properties of the rubber from which the belts are made. [0003] For example, Patent Document 1 discloses "a coiled conveyor belt that is conveyed between a driving pulley and an idler pulley and is equipped on a goods conveying The loss factor (tan...
