Embodiment 1

[0026] To prepare carbon nanotube slurry, use solid carbon nanotubes, liquid silane and naphthene oil in a weight ratio of 20 parts of carbon nanotubes, 60 parts of liquid silane, and 20 parts of naphthene oil, and use it under the condition of not exceeding 140°C Ball milling for at least 5 hours, (control the temperature to not exceed 140°C during ball milling to prevent self-crosslinking of liquid silane.) to make carbon nanotube slurry, in order to ensure the compatibility of carbon nanotubes and rubber, choose Hydroxylated surface-modified carbon nanotubes are used to make the carbon nanotubes react with the carboxyl groups of the silane coupling agent to form a chemical bond, which improves the reinforcing performance of the carbon nanotubes in the rubber compound. Improve the strength and wear resistance of the tread rubber.

Abstract

The invention relates to a carbon nano-tube tire with characteristics of high wear resistance and high roadholding capability, wherein the performance of the tire tread rubber is improved by using carbon nano-tubes with characteristics of ultra-high electric conductivity and high strength. The invention further provides a carbon nano-tube tire preparation method, wherein carbon nano-tubes can be effectively mixed into a rubber for producing a tire tread, and based on a general tire manufacturing raw material, by optimizing the ratio of the base material of the tire tread to the base material of the tire sidewall, compounding modification is performed by adding the carbon nano-tubes. According to the present invention, under the premise of the basically unchanged formulas of the tire treadrubber and the tire sidewall rubber according to the weight part, the multi-walled carbon nano-tubes and the white carbon black are added, and the carbon black for the tire, the type of the raw rubberand other ratios are optimized so as to maintain the size, the weight and the power performance of the tire consistent with the general tire and so as not to reduce various function indexes, such that the hysteresis loss tan[delta] of the composite rubber tire tread rubber added with the hydroxylated multi-walled carbon nano-tubes is increased by more than 20% at a temperature of -25 DEG C, and the roadholding capability of the tire is increased while the wear resistance of the tire is not reduced.

Description

technical field [0001] The invention relates to a high-performance, high-wearing, high-grip tire containing carbon nanotubes and a preparation method thereof. Background technique [0002] Tires are one of the most important parts of vehicles. In the cold winter in the north, there are often large areas of ice and snow on the road. When ordinary tires are driven on ice and snow roads, the tread rubber becomes hardened, the elasticity decreases, and the grip ability drops sharply. The braking distance of the vehicle is prolonged, and even out of control, resulting in a large number of traffic accidents. For this reason a lot of manufacturers have developed special tires for snow fields. In order to ensure the grip of the tires, a large amount of white carbon black is used, but at the same time, the wear resistance of the tires is reduced, and the service life of the tires is reduced. Contents of the invention [0003] The invention provides a high-wear-resistant and high-g...
