Problems solved by technology

This is mainly due to the fact that fillers such as carbon black, silica, and carbon nanotubes are mostly nano-sized, and their own agglomeration is very serious. It is difficult to achieve uniform dispersion by directly mixing them into the rubber matrix.
Uneven filler dispersion will directly affect the reinforcing effect of rubber, and it is also not conducive to reducing the hysteresis performance of rubber
Although it is also proposed in the prior art to pre-mix different types of fillers with a certain treatment method, and then add them to the rubber matrix, the processing capacity of the filler pre-mixing is small, which is only suitable for laboratory preparation and cannot be realized on a large scale. treatment, and the dispersion effect of the premixed filler in the rubber matrix and the low hysteresis performance of the rubber need to be further improved

Abstract

The invention provides a composite carbon material and a preparation method thereof, a rubber composite material and a tire, and relates to the technical field of carbon materials. According to the composite carbon material preparation method, an emulsifying liquid with a specific composition is sprayed to form atomized liquid droplets, the atomized liquid droplets react with primary structurally-modified carbon black existing in the form of flue gas, and by using a reinforcing filler and surface characteristics of the primary structurally-modified carbon black, the reinforcing filler reacts with and links to the primary structurally-modified carbon black to form the integration so as to obtain the composite carbon material. According to the present invention, the preparation method has simple and convenient operation, and is suitable for industrial-scale production, and the prepared composite carbon material has good low-hysteresis property. The present invention further provides a composite carbon material, which is prepared by using the composite carbon material preparation method, can meet the low-hysteresis performance requirement and the requirements of large-scale tire mixing, can be filled into different types of rubbers, is not limited to specific rubber latex, and has wide application range.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite carbon material and a preparation method thereof, a rubber composite material and a tire. Background technique [0002] In the past ten years, since the introduction of tire labels by the European Union, the domestic tire industry has vigorously developed green tires in response to the development of the industry. The general requirements of green tires are energy saving, safety, and durability, which are specifically reflected in the driving performance of low rolling resistance, high wet skid resistance, and high wear resistance. These three functions influence each other and restrict each other, and they are vividly called the "devil's triangle" function. In response to the advocacy of green tires and adapting to industry competition, upstream filler companies for tires are also striving to introduce low-hysteresis fillers. [0003] At present, from t...
