US 9,540,182 B2 · Abrasion-detection type conveyor belt and manufacturing method thereof

Abstract

Provided are an abrasion-detection type conveyor belt and a manufacturing method thereof. A polymer composition ratio of is set to 40-60% of styrene-butadiene rubber (SBR) and 60-40% of natural rubber (NR), and an adhesive strength between a cover rubber layer and an abrasion-detection color layer is set to 13 kN/m (33 kgf/inch). As compared to the existing product, material properties of the abrasion-detection color layer are improved to extend the available life of the abrasion detection type conveyor belt. The abrasion-detection type conveyor belt is cost-effective, simplifies a belt line, and reduces an inspection time.

Claims3

Dependent claims

An abrasion-detection type conveyor belt comprising:

a cover rubber layer including a top cover rubber layer, an intermediate cover rubber layer, and a bottom cover rubber layer;
carcasses inserted into the cover rubber layer, the carcasses having wavelike shapes;
and
an abrasion-detection-color layer disposed between the intermediate cover rubber layer and the top cover rubber layer,
wherein the abrasion-detection color layer is formed by setting a polymer composition ratio to 40%-60% of styrene-butadiene (SBR) and 60%-40% of natural rubber (NR).
