Abstract

The invention discloses an automotive rubber speed changing belt. The automotive rubber speed changing belt is prepared from the following raw materials in parts by weight: 25-35 parts of 1,3-butadiene, 25-35 parts of styrene, 20-26 parts of nickel naphthenate, 15-19 parts of triisobutyl aluminum, 10-16 parts of isoprene, 8-12 parts of ethylene, 8-12 parts of propylene, 10-16 parts of dicyclopentadiene, 5-9 parts of chloroprene, 3-5 parts of ethylidene norbornene, 20-24 parts of 1,4-hexadiene, 5-8 parts of clay, 5-8 parts of chalk, 7-12 parts of barite, 7-15 parts of carbon black, 5-9 parts of 2,6-tertiary butyl-4-methylphenol, 3-5 parts of toluene and 1-2 parts of toluene-heptane. The automotive rubber speed changing belt has the beneficial effects that the tenacity of the speed changing belt can be effectively improved, the aging speed of rubber of the speed changing belt is slowed down, and the service life of the automotive rubber speed changing belt is prolonged.

Description

technical field [0001] The invention relates to a rubber transmission belt for automobiles. Background technique [0002] Automotive transmission belts have either cloth-wrapped or edge-trimmed structures. They must have both high lateral stiffness and longitudinal flexibility, as well as high load-bearing capacity and long service life. Mainly used for belt type continuously variable speed changer. However, most of the existing transmission belts have poor toughness and are prone to aging. Contents of the invention [0003] The object of the present invention is to provide a rubber transmission belt for automobiles aiming at the defects in the above-mentioned prior art. [0004] In order to achieve the above object, the technical solution provided by the present invention is: a rubber transmission belt for automobiles, which is prepared from the following raw materials in parts by weight: 25-35 parts of 1,3-butadiene, 25-35 parts of styrene 35 parts, 20-26 parts of nic...
