Abstract

The invention relates to a motorcycle tire semi-hot melt adhesive and a preparation method thereof. The motorcycle tire semi-hot melt adhesive is prepared from the following ingredients in parts by weight: 114.1 to 119.6 parts of oil-extended butadiene-styrene rubber, 13 to 17 parts of styrene-butadiene-acrylonitrile copolymers, 70 to 75 parts of carbon black, 2 to 3 parts of zinc oxide, 1.5 to 2 parts of stearic acid, 12 to 16 parts of aromatic oil, 1.3 to 1.8 parts of anti-aging agents 4020, 0.6 to 1 part of anti-aging agents DTPD, 2.5 to 3.5 parts of protection wax, 1 to 2 parts of auxiliaries, 1 to 2 parts of homogenizing agents, 1.2 to 1.6 parts of sulphur, 1.5 to 2.5 parts of accelerants CBS and 0.1 to 0.3 part of accelerants DM. During the preparation, an internal mixer is used for performing primary mixing on the raw materials to prepare primary rubber master batch; then, still standing is performed; finally, the internal mixer is used for final mixing to obtain the finished product of the semi-hot melt adhesive. The preparation method is simple; the operation of the steps is easy; the prepared semi-hot melt adhesive tire rubber has better hot melting performance, so that a tire can fast become hot during running, and good ground grasping force can be provided; therefore a motorcycle has good starting accelerating performance and driving turn road safety performance.

Description

technical field [0001] The invention relates to a motorcycle tire semi-hot melt adhesive and a preparation method, belonging to the technical field of tire preparation. Background technique [0002] Motorcycle tire semi-hot melt adhesive is located on the tread part of the tire structure and is in direct contact with the road surface. Therefore, the motorcycle tire semi-hot melt adhesive should enable the tire to have rapid tire heating performance to provide good grip, so that the motorcycle has a better grip. Start acceleration performance and cornering performance. In the prior art, the motorcycle tire tread rubber formula adopted natural rubber and low-cis polybutadiene rubber, styrene-butadiene rubber (40 / 30 / 30) and used, and adopted N220 carbon black, so that the motorcycle tire tread Although the rubber has good wear resistance and high tear resistance, in actual use, the tire does not have rapid tire heating performance, and cannot provide suitable motorcycle tires ...
