Abstract

The invention relates to a high performance tire fabric rubber compound with a resorcinol-formaldehyde adhesion system, and comprises outer layer cord fabric rubber compound and cushion rubber compound. The key points are that: the invention is made by a plurality of raw materials, wherein, the adhesion system thereof adopts the resorcinol-formaldehyde adhesion system. The raw materials of the outer layer cord fabric rubber compound are natural rubber, rosin extended styrene-butadiene rubber, butadiene rubber, carbon black N330 / N660, zinc oxide, stearic acid, age inhibitor 4010NA / RD / BLE, oil-extended butadiene sulphur powder (S), aromatic oil, accelerant CZ / TMTD, RF-90 resin and adhesive RA-65. The raw materials of cushion the rubber compound are natural rubber, rosin extended styrene-butadiene rubber, carbon black N330 / N660, zinc oxide, stearic acid, age inhibitor 4020 / RD, oil-extended butadiene sulphur powder (S), aromatic oil, accelerant CZ / TMTD / DM, vulcanized agent DTDM, RF-90 resin and adhesive RA-65. The invention is essentially used for the outer layer cord fabric rubber compound and the cushion rubber compound in a bias tire. H pullout force can be obviously enhanced by using the rubber compound of the invention; the problem of cord fabric delaminating in practical use can be reduced by using the bias tire made from the rubber compound of the invention.

Description

Technical field [0001] The present invention relates to high performance tire cord compounds: outer cord compounds and breaker compounds containing a meta-formaldehyde bonding system. The outer ply compound and breaker compound are used in bias ply tire outer ply and breaker layers. Background technique [0002] With the rapid development of road traffic, there are more and more high-grade roads, and the phenomenon of high-speed overloading of automobiles is extremely common. Bias tires are facing severe challenges. Therefore, under such harsh driving conditions, the carcass of the tire is extremely susceptible to multiple deformations caused by strong radial, lateral, and circumferential forces, resulting in abnormalities such as bulges and delamination in bias-ply tires. The damage phenomenon will affect the service life of the tire. Since the bias tire is an elastic body composed of various rubber and other raw materials and multi-layer nylon cord and other skeleton mat...
