Abstract

The invention discloses a radial tire steel wire rubber and a preparation method thereof. The composition in parts by weight is: 5-15 parts of synthetic aluminum silicate, 5-15 parts of SB-boric ester surfactant, and 40-60 parts of modified rubber agent, 10-30 parts of liquid isoprene rubber; its preparation method is as follows: dry and mix the synthetic aluminum silicate and rubber modifier at 100-120°C; then mix SB-boric ester surfactant with The final powder is put into an activation reaction kettle for activation coupling; then liquid isoprene is added to the above active powder, mixed, prepared and packaged. The beneficial effects of the invention are: easy to use, the original formula remains unchanged, and 5-10 parts of steel wire functional rubber is directly added; the mechanical properties remain basically unchanged, and the vulcanization speed is slightly accelerated; the initial steel wire pulling force is increased by more than 20%, and after aging Increase by more than 10%.

Description

technical field [0001] The invention relates to a radial tire steel wire rubber and a preparation method thereof, belonging to the field of rubber chemical manufacturing. Background technique [0002] According to the national "Twelfth Five-Year Plan", functional new materials in radial tires are the key development areas to be supported. After the introduction and research and development in the 1980s, China's radial tires and giant engineering tires have developed rapidly and have reached the global production total. 50% of the volume, but there is still a big gap between the research and development and production of high-end tires and the advanced level of foreign countries. One of the most important reasons is that the R&D, innovation and application of functional new materials are seriously insufficient, which restricts the R&D and production of high-end tires in China. [0003] The unqualified rate in the process of tire production and use is high, and some domestic ...
