Tire tread mixture, tire tread made from tire tread mixture and tire

Abstract

The invention discloses a tire tread mixture, a tire tread made from the tire tread mixture and a tire. The tire tread mixture is prepared from the following raw materials in parts by mass: 30 to 45 parts of natural rubber, 30 to 45 parts of emulsion polymerized butadiene styrene rubber, 10 to 30 parts of cis-butadiene rubber, 45 to 75 parts of carbon black, 15 to 30 parts of white carbon black, 1.2 to 3.6 parts of silane coupling agent, 3 to 5 parts of zinc oxide, 1 to 2 parts of stearic acid, 2 to 4 parts of anti-aging agent, 1 to 2 parts of protective wax, 1 to 2 parts of sulphur, 10 to 20 parts of aromatic hydrocarbon oil, 1 to 2 parts of accelerant, 1 to 3 parts of tackifier, 1 to 3 parts of dispersing agent and 2 to 10 parts of non-slip material. According to the product provided by the invention, the trafficability characteristic and safety on a wet road surface and a smooth ice surface are improved, a proper amount of white carbon black is used and the friction between the product and the ground is larger, so that the controllability and the safety of a vehicle on the wet road surface and the smooth ice surface are greatly improved, and meanwhile, the tire rolling resistance and heat generation in a common environment cannot be affected.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a tire tread compound suitable for use in all seasons and the tire tread and tire made therefrom. Background technique [0002] Most of the products currently on the market use solution-polymerized styrene-butadiene SSBR+highly dispersed silica to achieve the desired purpose, but there are technical problems such as large rolling resistance, non-wear resistance, and difficulty in dispersing silica. Among them, solution-polymerized styrene-butadiene rubber The market price is 30 yuan / kg, while the market price of EPSB is less than 10 yuan / kg. In addition, the anti-wet slipping materials used in the market can play a certain role are composite materials of carbon, oxygen, boron, nitrogen and other graft copolymers modified by the surface of organic polymers. The use is limited by the manufacturer, and the effect Insufficient assurance. Although the use of a foaming agent can help p...

Problems solved by technology

[0002] Most of the products currently on the market use solution-polymerized styrene-butadiene SSBR+highly dispersed silica to achieve the desired purpose, but there are technical problems such as large rolling resistance, non-wear resistance, and difficulty in dispersing silica. Among them, solution-polymerized styrene-butadiene rubber The market price is 30 yuan / kg, while the market price of EPSB is less than 10 yuan / kg

In addition, the anti-wet slipping materials used in the market can play a certain role are composite materials of carbon, oxygen, boron, nitrogen and other graft copolymers modified by the surface of organic polymers. The use is limited by the manufacturer, and the effect Insufficient assurance

Although the use of foaming agent can help anti-skid at low temperature, it cannot be used when the temperature is high (the oil consumption is too high and must be replaced)

At present, most of the existing technologies use a large amount of highly dispersed white carbon black to make up for its shortcomings, or increase the amount of solution-polymerized styrene-butadiene rubber SSBR (high price) to improve
