Abstract

The invention relates to the field of rubber composite material preparation, in particular to a tread rubber composite material containing a modified graphene oxide compound and a preparation method of the tread rubber composite material containing the modified graphene oxide compound.The composite material comprises, by weight, 100 parts of matrix rubber, 30-70 parts of high-dispersion white carbon black, 2-6 parts of a silane coupling agent, 5-25 parts of carbon black, 2-8 parts of a plasticizer, 1-3 parts of an activating agent, 1-3 parts of an anti-ageing agent, 1-3 parts of a vulcanization accelerator, 1-2 parts of common sulfur and 0.1-0.3 part of a scorch retarder.The matrix rubber is mixed rubber formed by proportional mixing of natural rubber, polybutadiene rubber and butadiene styrene rubber, and the natural rubber in the matrix rubber is added in two times.The modified graphene oxide compound is further added to the composite material and formed by part of the natural rubber in the matrix rubber, graphene oxide and a graphene oxide modifying agent.Due to addition of the modified graphene oxide compound, tensile strength, stress at definite elongation, hardness, abrasion resistance and the like of the tread rubber composite material are evidently improved.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a tread rubber composite material containing a modified graphene oxide compound and a preparation method thereof. Background technique [0002] Tires play the role of bearing load, buffering impact, transmitting driving force and braking force, and providing steering maneuverability when the car is running. It is one of the most important parts of the car. The tire tread directly contacts the ground. In addition to protecting the carcass, it should also have wear resistance and cut resistance, and can transmit the traction and braking force of the wheel, and buffer the vibration and impact transmitted by the ground. The tread rubber is specially designed for balancing Wear, traction, handling and rolling resistance are configured. Tread rubber must work effectively under a variety of driving conditions and meet customer expectations for tires with high wear resistance, high durab...
