Example Embodiment

[0019] Example 1:

[0020] The present invention prepares graphene electrostatic conductive tire on the basis of medium-duty truck tire tread rubber and sidewall rubber. The specific preparation process includes the following steps:

[0021] (1) Plastic / mixing: The tread rubber is composed of two parts: crown rubber and tread base rubber. First take 30 parts by weight of butadiene rubber (BR) and 70 parts by weight of styrene butadiene rubber (SBR) and 3 parts by weight. Part of the anti-aging agent is plasticized at 45-50℃ for 15-20min to obtain the plasticized compound; then the plasticized compound is mixed by a two-stage mixing process to obtain the crown compound. , First mix the plasticized rubber at 35-55℃ for 3-5min, then add 40-59.9 parts by weight of hard carbon black, 11 parts by weight of process oil, 3 parts by weight of zinc oxide, 2 parts by weight of hard Fatty acid, 2 parts by weight of microcrystalline wax, 0.7 parts by weight of anti-scorching agent are mixed un...

[0026] Example 2:

[0027] In this example, the conductivity of the graphene electrostatic conductive tire prepared in Example 1 was tested at 25°C, as figure 2 As shown, when the amount of graphene added is 0.1 part by weight, 0.5 part by weight, and 1 part by weight, the specific surface area and conductivity of the graphene powder are 1800m respectively. 2 / g、9.7×10 5 s / m(1), 1600m 2 / g、6×10 5 s / m(2),1200m 2 / g、1×10 5 s / m(3), the test result graph shows that with the increase of graphene addition, the tire conductivity gradually increases; the higher the specific surface area and conductivity of graphene powder, the higher the tire conductivity.

Example Embodiment

[0028] Example 3:

[0029] This example illustrates the electrostatic conduction mechanism of the graphene electrostatic conduction tire prepared in Example 1, such as image 3 As shown, the tire (side 4 and tread 5) made of graphene powder is fitted and connected with the rim 2 on the metal wheel hub 1 of the automobile, and the static electricity (+) of the vehicle body is discharged through the ground contact surface 6 of the tire tread 5, The static electricity of the car body can be continuously and reliably discharged at all times, which has an irreplaceable advantage for preventing the hazards of static electricity in the transportation of inflammable and explosive materials.

Abstract

The invention belongs to the technical field of composite material preparation and relates to a method for preparing a graphene static conductive tire. According to the method, on the premise that tread rubber and side wall rubber of a general tire are matched according to a weight ratio which is basically unchanged, 0.1-20 weight parts of graphene is added according to the difference in electric conductivity and specific area of the selected graphene to optimize the ratios of hard carbon black and other materials, so that the electric conductivity of the tread and the side wall of a composite rubber tire modified by adding the graphene is not lower than 10<-8> S/m at the room temperature. The technology is simple, price is low, and application and popularization are convenient. The method is suitable for various tires, technical transformation of original production equipment is not needed, and the overall appearance, size, weight and dynamic property of the modified tire are not changed; meanwhile, the wearing resistance, thermal conductivity and aging resistance of the tire are improved.

Description

Technical field: [0001] The invention belongs to the technical field of composite material preparation, and relates to a method for preparing a graphene and colloid composite modified graphene static conductive tire. Background technique: [0002] The generation and existence of static electricity is an objective natural phenomenon that exists on objects and human bodies. The operation and driving of automobile equipment intensifies the accumulation of charges, and its potential can reach thousands or even hundreds of thousands of volts. Patients with cardiac pacemakers can cause a sudden increase in heart rate or sudden arrest, and more seriously, it can cause deflagration of vehicles, especially vehicles transporting flammable and explosive materials, resulting in disastrous consequences. The anti-static technology and equipment currently used in automobiles cannot guarantee reliable and uninterrupted elimination of static electricity on the car body. For example, towed a...
