Abstract

The invention provides a tire bead wire rubber and a preparation method thereof and relates to the technical field of chemical materials. The steel wire rubber comprises the following raw materials inparts by weight: 70-120 parts of raw rubber; 1.0 to 4.0 parts of nanometer zinc oxide; 1.0-4.0 parts of stearic acid; 1.0-3.2 parts of dispersing agent; 13 to 30 parts of filling reinforcing agent; 3.0 to 8.0 parts of super tackifying resin; 1.0 to 3.5 parts of resorcinol; 1.0 to 3.0 parts of cobalt boroacylate; 3.0 to 10.0 parts of reinforcing resin; 5.0 to 15.0 parts of graphite powder; 2.0 to5.5 parts of C5 resin; 3.0 to 10.0 parts of an anti-shoulder-empty agent; 5.0 to 10.0 parts of environment-friendly aromatic hydrocarbon oil; 90 to 100 parts of carbon black; 1.0 to 2.5 parts of a silane coupling agent; 2.0 to 6.0 parts of sulfur; 2.0 to 7.0 parts of an accelerant; and 1.7 to 6.0 parts of a functional auxiliary agent. The raw rubber comprises natural rubber, butadiene styrene rubber, butadiene rubber and solution polymerized butadiene styrene rubber. The steel wire rubber disclosed by the invention has the characteristics of high hardness and high strength, is beneficial to increasing the rigidity and firmness of a tire bead part, has high bonding strength with a steel wire, and reduces the problems of tire bead explosion, void and steel wire leakage caused by stripping ofthe steel wire and the steel wire rubber.

Description

Technical field [0001] The invention relates to the technical field of chemical materials, in particular to a tire bead steel wire rubber and a preparation method thereof. Background technique [0002] The tire is one of the indispensable parts of the car and plays an important role in the driving process of the car. On the one hand, the tires are in direct contact with the road to ensure good adhesion between the wheels and the road, and to improve the traction, braking and passability of the car; on the other hand, the tires and the car suspension work together to alleviate the car’s impact when driving. The impact to ensure that the car has good seating comfort and driving smoothness. The quality of tires plays a vital role in the safety of automobile driving. Therefore, the improvement of tire materials has attracted more and more attention. [0003] The bead on the tire is directly combined with the rim. The bead is mainly composed of bead wire, bead wire rubber, carcass ply...
