Abstract

The invention discloses an anti-static and high-wear-resistant tire tread rubber and a preparation method thereof. The nanometer carbon black with a specific DBP value is selected to be compounded with reduced graphene oxide in a specific ratio, and then mixed with a conventional tread rubber to obtain the compound. . Nano-carbon blacks with different DBP values ​​are distributed in different areas on the surface of reduced graphene oxide, forming a unique nano-composite structure, showing excellent electrical conductivity. After adding conventional tread rubber, it can effectively improve its electrical conductivity and wear resistance. properties without reducing tensile strength. At the same time, the addition amount of graphene and carbon black is significantly lower than that of conventional conductive additives, which has the advantages of low cost, high addition, and balanced performance, and can be used in automobile and aircraft tires.

Description

technical field [0001] The invention belongs to the field of tire materials, in particular to an antistatic and highly wear-resistant tire tread rubber and a preparation method thereof. Background technique [0002] In daily life, when two objects of different materials are in contact and then separated, static electricity can be generated. This is because one object loses a certain amount of charge and becomes positively charged, while the other object gains charge and becomes negatively charged. These charges are difficult to neutralize easily. It will gradually accumulate to form static electricity. Static electricity itself is a very common phenomenon, but when the static electricity is accumulated and released violently, it is very easy to cause circuit breakdown, information interference, fire, electric shock and other phenomena, which may cause discomfort to the human body, or interfere with electromagnetic signals, causing Dizziness, headache, breakdown of electroni...
