Trimming type helical tooth-shaped triangular belt and production process thereof

Abstract

The invention discloses an edge cutting type helical tooth-shaped triangular belt and a production process thereof, the edge cutting type helical tooth-shaped triangular belt has good mechanical property, is not easy to generate heat and has good heat dissipation performance, the technical scheme is that the edge cutting type helical tooth-shaped triangular belt comprises a fiber glue layer, and the fiber glue layer comprises the following raw materials in parts by weight: 100 parts of chloroprene rubber adhesive; 10 to 20 parts of butadiene-styrene rubber; 10 to 20 parts of cis-butadiene rubber; 20 to 30 parts of carbon black; 1.5 parts of an anti-aging agent RD; 1-3 parts of an accelerant DM; 1-3 parts of a plasticizer DOP; 4 parts of magnesium oxide; 5 parts of zinc oxide; 20-30 parts of modified calcium carbonate; 10 to 20 parts of modified polyester fiber; the triangular belt is suitable for the technical field of triangular belts.

Description

technical field [0001] The invention belongs to the technical field of V-belts, and particularly relates to a trimmed helical-toothed V-belt and a production process thereof. Background technique [0002] V-belt is a kind of conveyor belt widely used in various machinery. It is mainly composed of industrial canvas, polyester soft cord and fiber rubber layer. The fiber rubber layer is mainly composed of natural rubber, styrene-butadiene rubber, reclaimed rubber and compounding agents. (Zinc oxide, stearic acid, antioxidant, carbon black, softener, etc.). During the use of the V-belt, the friction between the belt and the pulley will increase, and the heat of 110 ° C will be generated. With the operation of the V-belt, the heat emitted is always surrounded by the belt body, and the ambient temperature increases. , so that the temperature of the belt itself will also increase. Rubber is a thermoplastic material. When the temperature rises, the fatigue resistance and flexion re...

AI Technical Summary

Problems solved by technology

During the use of the V-belt, the friction between the pulley and the pulley will increase and generate heat of 110°C. With the operation of the V-belt, the heat emitted will always surround the belt body, and the ambient temperature will increase. , so that the temperature of the belt body itself will also increase. Rubber is a thermoplastic material. When the temperature rises, the fatigue resistance and flexural performance will deteriorate, making the V-belt easily damaged, malfunctioning, and the service life will be shortened.

[0003] In response to the above problems, corresponding improvements have been made in the prior art, such as the content disclosed in the application number CN201710575194.1, but in order to ensure the strength of the V-belt, usually A large amount of carbon black needs to be added as a reinforcing material, but while carbon black improves the mechanical properties of vulcanized rubber, it significantly increases the compression heat generation of vulcanized rubber; based on the above problems, further research on the raw material ratio and production process of the V-belt is required
