Abstract

The invention discloses a formula for tread rubber of a tire which is suitable for various pavement conditions. The formula is formed by adoption of natural rubber as a main material, cis-1, 4-polybutadiene rubber, intermediate and ultra abrasion resistant carbon black, high-dispersity white carbon black, a silane coupling agent, an anti-cracking resin and a heat stabilizer as main auxiliary materials, and zinc oxide, a stearic acid, a para-phenylene diamine anti-ageing agent, a ketoamine anti-ageing agent, insoluble sulfur, a sulfenamide type accelerator as auxiliary materials. The formula has the advantages that: the tread rubber is made to have the advantages of high tensile strength, high tear strength, high stress at definite elongation, good puncture resistance, low dynamic heat generation, good thermal stability, good abrasion resistance and good flexure and crack resistance. When the tread rubber is used for the tire, the tire is suitable for various pavement conditions, not only is suitable for highway pavements and high-speed conditions but also is suitable for off-highway conditions such as soil pavements, sand and stone pavements and so on, and has good abrasion resistance and long service life.

Description

technical field [0001] The invention relates to tire tread rubber, in particular to a formula of tire tread rubber which can be used under various road conditions. Background technique [0002] A special-purpose vehicle, in addition to high-speed driving on the highway, sometimes also needs to be driven on dirt and gravel roads. Existing tire tread rubber can only adapt to one of the conditions of use in road conditions or mud and gravel road conditions, and cannot adapt to the use conditions of the above two types of road surfaces at the same time. Contents of the invention [0003] The purpose of the present invention is to disclose a tire tread rubber formula that can be used under various road conditions. It has the advantages of low heat generation, good thermal stability, good wear resistance and good flex crack resistance. The tires using the tread compound have good puncture resistance and crack resistance when used on dirt and gravel roads, and have a long servi...
