Problems solved by technology

Compared with black tires, the existing colored tires are not suitable for truck tires due to their poor wear resistance and short service life.
In addition, the tire tread rubber composition of the truck radial tire usually uses carbon black as the filling and reinforcing system. The applicat

Example Embodiment

[0037] Example 1

[0038] In this embodiment, natural rubber, rare earth butadiene rubber and styrene butadiene rubber are used as the base rubber. Each component of the composition of the embodiment 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 raw rubber for 3 to 4 minutes with a closed rubber mixer at a temperature in the range of 160 to 170°C. Glue, complete the preparation of a section of plasticized rubber; after the film is parked for 8 hours, add a section of plasticized rubber, synthetic rubber, high dispersibility silica and all compounding agents except the vulcanization system in the closed rubber mixing machine. Refining for 3 to 4 minutes at 150-160℃ to discharge the rubber to complete the ...

Example Embodiment

[0040] Example 2

[0041] In this embodiment, natural rubber and rare earth butadiene rubber are used as the base rubber. The mixing method is the same as in Example 1. After the mixed rubber material is parked for 6 hours, the sample is vulcanized at 151°C for 20min, 30min, and 40min with a steam vulcanizer. Perform various performance tests according to corresponding national standards.

Abstract

The invention discloses a rubber composition for a color truck radial tire tread. The rubber composition comprises, by weight, 100 parts of a rubber matrix, 5-8 parts of an active agent, 40-80 parts of white carbon black, 4-8 parts of a silane coupling agent, 4-10 parts of light color rubber oil, 1.5-3.5 parts of an accelerator, 4-8 parts of an anti-aging agent, 1-2 parts of a vulcanizing agent, 5-8 parts of an antistatic agent, and 3-6 parts of a coloring agent, wherein the rubber matrix comprises a natural rubber and rare earth polybutadiene rubber, or comprises a natural rubber, rare earthpolybutadiene rubber and styrene butadiene rubber, the white carbon black is the high dispersible precipitated white carbon black, the accelerator is the combination of an accelerator CBS and an accelerator DPG, the anti-aging agent is the combination of three components of a non-polluting type light color antiozidant, a non-polluting type light color antioxidant and an anti-aging agent RD, the vulcanizing agent is sulfur, and the antistatic agent is a polyether antistatic agent. With the rubber composition of the present invention, the tensile strength of the prepared tread is 25 MPa, and the elongation at break is more than 500%. The rubber composition of the present invention is mainly used for the color truck radial tire tread.

Description

technical field [0001] The invention relates to a tire tread, including a rubber composition reinforced by white carbon black, in particular to a rubber composition used for the tread of a colored load-carrying radial tire. [0002] More specifically, the present invention relates to a rubber composition for treads of colored radial truck tires mainly colored by a colorant and reinforced with silica. Background technique [0003] In recent years, increasing fuel costs and enactment of environmental regulations have increased the need to improve fuel economy in the automotive industry. In terms of fuel economy, the tread rubber composition accounts for a large proportion of tire components. As is known, high speed, safety, comfort, energy saving, etc. have become the basic requirements for tire performance. It is expected that the tire has high grip (great friction between the tire and the ground, especially wet ground), low fuel consumption (small rolling resistance), low ...
