Embodiment 1

[0020] The present invention prepares graphene static conductive tires on the basis of medium-sized truck tire tread rubber and sidewall rubber, and its specific preparation process comprises the following steps:

[0021] (1), plastic / mixing: the tread rubber is composed of two parts: the crown rubber and the tread base rubber. One part of anti-aging agent was masticated at 45-50°C for 15-20 minutes to obtain the masticated rubber; and then the two-stage mixing process was used to knead the masticated rubber to obtain the crown rubber. First, mix the masticated rubber for 3-5min at 35-55°C, and then add 40-59.9 parts by weight of hard carbon black, 11 parts by weight of operating oil, 3 parts by weight of zinc oxide, and 2 parts by weight of hard carbon black. Fatty acid, 2 parts by weight of microcrystalline wax, and 0.7 parts by weight of anti-scorch agent are mixed evenly, and finally 0.1-20 parts by weight of graphene, 1.3 parts by weight of accelerator and 1.8 parts by we...

Embodiment 2

[0027] This embodiment tests the conductivity of the graphene static conductive tire prepared in Example 1 at 25°C, as figure 2 As shown, when the added amount of graphene is 0.1 weight part, 0.5 weight part and 1 weight part respectively, the specific surface area and conductivity of graphene powder are 1800m 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 curve shows that with the increase of graphene addition, the conductivity of the tire gradually increases; the higher the specific surface area and conductivity of the graphene powder, the higher the conductivity of the tire.

Embodiment 3

[0029] This embodiment illustrates the static conduction mechanism of the graphene static conduction tire prepared in Example 1, as image 3 As shown, the tire (sidewall 4 and tread 5) made by adding 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 derived through the tire tread 5 contact surface 6, It can continuously and reliably export the static electricity of the car body at all times, and has an irreplaceable advantage in eliminating static electricity hazards for flammable and explosive goods transport vehicles.

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...
