Problems solved by technology

Currently using furnace carbon black, such as N234, N115, etc., although the wear resistance meets the requirements, but the heat generation is high, which cannot meet the requirements of low rolling resistance tires
There are many shortcomings in the production and use of the current tire compound formula: uneven dispersion of carbon black and small materials, poor adhesion with the transition layer, and easy to appear bubbles when laminating
[0005] In order to improve the wear resistance of the tread rubber, the current prior art increases the content of butadiene rubber in the formula by a large proportion. Tread rubber has poor puncture resistance
The purpose of using super wear-resistant furnace black (such as N115) is to use the excellent reinforcing effect of super wear-resistant furnace black on rubber to improve the wear resistance of the tread rubber, but it generates high heat and is difficult to operate during the processing of semi-finished products Bring trouble to the production process
Since more synthetic rubber is used in the tread rubber, the adhesive ability of the rubber material is reduced, and it is easy to cause the problem of separation between the tread and the carcass, which will also affect the service life of the tire.

Description

technical field [0001] The invention belongs to the field of rubber tire manufacturing, and in particular relates to a wear-resistant, puncture-resistant, low-resistance tire compound and a manufacturing method thereof. Background technique [0002] The rubber compound is made by mixing and mixing raw materials such as carbon black, natural rubber or synthetic rubber, and additives. As the main processing object and carrier in the tire manufacturing process, the proportion of rubber in the rubber compound usually reaches about half. Chemical substances such as additives can be used to change the physical properties of rubber such as strength, plasticity, elasticity, and durability. All the semi-finished rubber parts on the tire, such as tread, sidewall and apex, etc., are processed from the rubber compound in the subsequent manufacturing process. [0003] To reduce tire rolling resistance from the perspective of formula, it is necessary to optimize rubber types and reinfor...
