Example Embodiment

[0016] Example 1

[0017] In this embodiment, each component of the composition is calculated in parts by mass, and the specific components are shown in Table 1. The mixing of the rubber composition can be performed by a method known to those skilled in rubber mixing. For example, each component is generally mixed in at least two stages. The mixing process of the rubber composition is to masticate the natural rubber for 3 to 4 minutes with a closed rubber mixing machine, and the temperature is within the range of 155 to 165 ℃. After the film is parked for 8 hours, add a section of plasticized rubber, synthetic rubber, high-dispersible white carbon black and all compounding agents except the vulcanization system to the airtight rubber mixer for mixing. Discharge the rubber in the range of 150-160℃ for 3~4min to complete the preparation of the second-stage masterbatch; after the film is parked for 8 hours, add the second-stage masterbatch and all the compounding agents of the vulc...

Example Embodiment

[0022] Example 2

[0023] The difference from Example 1 is that the raw materials of the mass parts shown in Table 2 are selected.

[0024] The mixing of the rubber composition can be performed by a method known to those skilled in rubber mixing. The mixing process of the rubber composition is to masticate the natural rubber for 3 to 4 minutes with a closed rubber mixer, and discharge the rubber at a temperature in the range of 155 to 165°C to complete the preparation of a section of plasticized rubber; after the film is parked for 8 hours, Then add a stage of plasticizing rubber, synthetic rubber, highly dispersible white carbon black and all the compounding agents except the vulcanization system into the closed rubber mixing machine, and mix for 3~4min at 150~160℃ to discharge the rubber to complete the second stage Preparation of the masterbatch; after the film is parked for 8 hours, add the second-stage masterbatch and all the compounding agents of the vulcanization system in ...

Example Embodiment

[0029] Example 3

[0030] The difference from Examples 1 and 2 is that the raw materials with the mass parts shown in Table 3 are selected.

[0031] The mixing of the rubber composition can be carried out by a method known to those skilled in rubber mixing. The mixing process of the rubber composition is to masticate the natural rubber for 3 to 4 minutes with a closed rubber mixer, and discharge the rubber at a temperature in the range of 155 to 165°C to complete the preparation of a section of plasticized rubber; after the film is parked for 8 hours, Then add a stage of plasticizing rubber, synthetic rubber, highly dispersible white carbon black and all the compounding agents except the vulcanization system into the closed rubber mixing machine, and mix for 3~4min at 150~160℃ to discharge the rubber to complete the second stage Preparation of the masterbatch; after the film is parked for 8 hours, add the second-stage masterbatch and all the compounding agents of the vulcanization...

Abstract

The invention relates to a composition for a tire tread of a tire, in particular to the cowhells color rubber composition for a tire tread of a load bearing radial tire. The cowhells color rubber composition for the tire tread of the load bearing radial tire is characterized by being prepared from the following ingredients in parts by weight: 100 parts of base rubber, 4.0 to 8.0 parts of activating agents, 40 to 80 parts of white carbon black, 4.0 to 8.0 parts of silane coupling agents, 1.0 to 3.0 parts of carbon black dispersing agents, 1.5 to 3.0 parts of accelerants, 3.0 to 6.0 parts of anti-aging agents, 1.0 to 2.0 parts of vulcanizing agents, 0.1 to 0.3 part of scorch retarders and 1.0 to 3.0 parts of processing agents. The cowhells color rubber composition for the tire tread of the load bearing radial tire has the advantages that the attractive degree of the tire is improved; meanwhile, the tire rolling resistance is also reduced; the fuel saving and environment-friendly requirements can be met.

Description

technical field [0001] The invention relates to a composition for tire treads, in particular to a tendon-colored rubber composition for load radial tire treads. Background technique [0002] With the development of the automobile industry, automobile tires are developing in the direction of safety, environmental protection, and greenness. Therefore, non-petroleum resources such as natural rubber and white carbon black are getting more and more attention. Products with more excellent performance requirements. And, along with the increase of fuel costs and the enactment of environmental regulations, the demand for automobile fuel economy is enhanced, and the tread rubber composition accounts for a large proportion in each part of the tire, therefore, the economical effect of the tread rubber composition Sex also increases. In addition, traditional tires are all black, which cannot bring beautiful visual enjoyment to people. Contents of the invention [0003] In order to m...
