Problems solved by technology

[0003] The raw material of the V-ribbed belt currently used in automobile engines is composed of neoprene and related additives, which has poor resistance to high and low temperatures, is not stable enough, and has a short service life due to aging
In addition, the biggest disadvantage is that there is a lot of noise during transmission. When used at low speeds or with rapid changes in angular velocity, and after a period of use, the wedge surface is worn, hardened or the tension is loose, or after being exposed to water in rainy days, it will emit harsh sharp noises during transmission. The sound affects the overall performance of the car and is also detrimental to the physical and mental health of the human body.

Abstract

The invention discloses an automotive V-ribbed belt and a manufacture method thereof. The automotive V-ribbed belt comprises a belt body, wherein the belt body comprises the following raw materials in parts by weight: 100 parts of neoprene, 2.8-3.5 parts of age inhibitor, 35-45 parts of strengthening agent, 6-8 parts of softening agent, 8-12 parts of vulcanizing agent, 1-1.5 parts of promoting agent, 1.5-2.5 parts of dispersant, 15-25 parts of chopped fiber and 1.5-2.5 parts of adhesive. The invention also discloses a manufacture method of the automotive V-ribbed belt. The automotive V-ribbed belt has the characteristics of favorable high and low temperature resistance, wear resistance, high tensile strength and long service life; and through the rib milling technique, fiber floss with the length of 1-3 mm is exposed on the rib surface to enable the friction factor of the automotive V-ribbed belt to be stable, thereby greatly reducing the noise produced when the V-ribbed belt is driven.

Description

technical field [0001] The invention relates to a transmission component, in particular to an automobile V-ribbed belt and a manufacturing method thereof. Background technique [0002] Chinese invention patent 200610049670.8 discloses an elastic V-ribbed belt, including a belt body, a belt wedge and a back. There is a nylon skeleton in the belt body, and a layer of high-modulus low-shrinkage HMLS is added to the back. For the calendered polyester cord fabric, the patent also specifically designs the rubber formula, so that the elongation of the belt body and belt wedge matches the elongation of the skeleton material, and has a certain degree of resilience. [0003] The raw material of the V-ribbed belt currently used in automobile engines is composed of neoprene and related additives, which is poor in high and low temperature resistance, not stable enough, and has a short service life due to aging. In addition, the biggest disadvantage is that there is a lot of noise during...
