Problems solved by technology

[0007] Although radial tires have many advantages, with the development of society and the improvement of people's requirements, green tires such as good elasticity, low rolling resistance, low fuel consumption, wear resistance, and large bearing capacity have become a new development direction, and traditional radial tires Contains a large amount of polycyclic aromatic hydrocarbons (DAE), these substances will pollute the environment in the processing, use and waste disposal of tires, and have carcinogenic effects on the human body, so their use has been increasingly restricted. Developed countries represented by the European Union countries have issued environmental protection regulations restricting polycyclic aromatic hydrocarbons. The implementation of these regulations has put a lot of pressure on the relevant enterprises engaged in the production and export of rubber products and additives in my country. Therefore, tires with environmental protection and high comprehensive performance Become the research and development focus of major tire manufacturers

Embodiment 1

[0017] A low rolling resistance semi-steel radial tire tread compound formulation, characterized in that the formulation comprises the following components: 23.1 parts of emulsion polystyrene butadiene rubber, 101 parts of solution polystyrene butadiene rubber, 7.8 parts of new technology carbon black, white carbon black 67 parts, super silane coupling agent Si7476 parts, environmental protection oil 4.2 parts, zinc oxide 2.5 parts, stearic acid 1.8 parts, sulfur 1.6 parts, accelerator NS1.6 parts.

Embodiment 2

[0019] A low rolling resistance semi-steel radial tire tread compound formulation, characterized in that the formulation includes the following components: 24 parts of emulsion polystyrene butadiene rubber, 102 parts of solution polystyrene butadiene rubber, 8.7 parts of new technology carbon black, white carbon black 69 parts, super silane coupling agent Si7478 parts, environmental protection oil 6 parts, zinc oxide 2.8 parts, stearic acid 2.2 parts, sulfur 2 parts, accelerator NS 2 parts.

Embodiment 3

[0021] A low rolling resistance semi-steel radial tire tread compound formulation, characterized in that the formulation includes the following components: 25 parts of emulsion polystyrene butadiene rubber, 103 parts of solution polystyrene butadiene rubber, 10 parts of new technology carbon black, white carbon black 70 parts, super silane coupling agent Si7477 parts, environmental protection oil 5 parts, zinc oxide 3 parts, stearic acid 2 parts, sulfur 2.2 parts, accelerator NS1.8 parts.

[0022] As the above-mentioned preferred scheme, when the reinforcing agent white carbon black and the super silane coupling agent Si747 are mixed with the common coupling agent, the rebound rate of the rubber produced is increased by 20%, and the loss factor (tanδ) at 60°C Reduced by 40%, Payne effect (△G) reduced by 50%, volatile matter reduced by 80%, at the same time can reduce the Mooney viscosity, improve the dispersion performance of silica and improve the mixing efficiency.

Abstract

The invention relates to a formula of tread rubber of a low-rolling-resistance semi-steel radial tire. The formula is prepared from the following components: 20 to 30 parts of emulsion polymerized butadiene styrene rubber, 80 to 130 parts of solution polymerized butadiene styrene rubber, 5 to 20 parts of new-process carbon black, 50 to 125 parts of white carbon black, 2 to 15 parts of a super silane coupling agent Si747, 3 to 10 parts of environment-friendly oil, 2 to 6 parts of zinc oxide, 1.2 to 5.6 parts of stearic acid, 0.8 to 3.2 parts of sulfur and 1.2 to 4.2 parts of an accelerant NS. The tire produced by the formula provided by the invention has good environment-friendly property, low rolling resistance, high wear resistance and less generated heat, the oil consumption of vehicles can be reduced and the service life of the vehicle tire is prolonged.

Description

technical field [0001] The invention relates to an environment-friendly green low-rolling-resistance tire formula, which belongs to the field of tire manufacturing, in particular to a low-rolling-resistance semi-steel radial tire tread rubber formula. Background technique [0002] With the continuous development of tire technology, most of the tires used in cars are radial tires. Radial tires are different from bias tires, mainly in the following aspects: [0003] 1. Can drive at high speed. From the perspective of speed, the speed of a car mainly depends on the engine, but the tires shoulder the sacred responsibility of fulfilling this mission. During the running of the tire, the contact part between the tire and the ground bends and rotates away due to the load. When the ground is on the ground, the curved part will return to its original shape with the pressure inside the tire, but if the tire pressure is insufficient or the speed is too fast, the curved part will not ha...
