Abstract

The invention discloses a high-performance triangular belt. The triangular belt comprises a strong layer, the upper portion of the strong layer is provided with a stretching layer, a compression layeris arranged at the lower portion of the strong layer, and the outer side of the stretching layer and the outer side of the compression layer are wrapped with a wrapping cloth layer. The strong layeris made of surface modified tempered monofilament. The tempered monofilament is adopted as the material of the strong layer, and stretching and other stress generated in the triangular belt running process are improved; meanwhile, the primer material formula is optimized, the physical mechanical performance and bending resisting and fatigue resisting performance of the material are improved, the triangular glue production technology is optimized and strictly controlled, the material technology efficiency is improved, and accordingly the product quality and character are improved.

Description

technical field [0001] The invention relates to the technical field of V-belts, in particular to a high-performance V-belt and a preparation method thereof. Background technique [0002] There are two types of V-belts: special belt core structure and rope core structure, which are composed of four parts: covering cloth, top glue, tensile body and bottom glue; the V-belt with rope core structure is easy to manufacture, the tensile strength is average, and the price is low. V-belts with special core structure have good toughness and high strength, and are suitable for occasions with high rotational speed. V-belts made of rubber are generally composed of cloth covering layer, stretch layer (top rubber), strength layer (tensile layer) and compression layer. Layer (primer) and other parts. [0003] Covering layer, the covering layer is composed of plain rubber canvas (mainly cotton canvas and polyester-cotton canvas) cut diagonally at 45°, has excellent stretchability and fricti...
