Abstract

The invention relates to a motorcycle tire side formula, which comprises the following raw materials in parts by weight: 20 parts of NR, 20 parts of BR9000, 120 parts of reclaimed rubber, 3 parts of nanometer zinc oxide, 2 parts of stearic acid, 3.5 parts of anti-4010 NA, 1 part of anti-RD, 2 parts of anti-Ble-w, 1.5 parts of paraffin, 4 parts of coumarone-indene resin, 40 parts of N330, 20 partsof aromatic oil, 2 parts of sulfur powder, 1 part of catalytic CZ and 0.1 part of scorch retarder PVI. The formula is high in performance, low in cost and high in operability.

Description

technical field [0001] The invention relates to the field of rubber tires, in particular to a motorcycle sidewall formula. Background technique [0002] At present, it has become a trend to design the sidewall of motorcycle tires with flex resistance, aging resistance, and high puncture resistance, and the production cost increases. How to maintain a balance between the good side rubber performance and cost of motorcycle tire sidewalls, and achieve The biggest benefit is an important problem facing the R&D personnel. In the prior art, the tire crown and the sidewall generally use a unified formula. Such a design makes it impossible to achieve the performance requirements of the tire crown and the sidewall through an integral extrusion process one by one. Contents of the invention [0003] The purpose of the present invention is to provide a motorcycle tire sidewall formula, which saves cost and maintains good rubber properties. [0004] The technical scheme that the pre...
