Embodiment 1～3

[0077] In the mixing process of steel wire glue, first put isoprene gum and trans-type isoprene gum, traditional Chinese medicine (including zinc oxide, stearic acid, anti-aging agent, coumarone resin, binding resin, cobalt) in the internal mixer in sequence. Salt), carbon black and aromatic oil, debinding at a temperature not higher than 170°C to obtain masterbatch. Then put the masterbatch and small medicine (including resin curing agent, accelerator, sulfur) in the internal mixer below 70°C in sequence, and then discharge the glue at a temperature not higher than 110°C to obtain steel wire glue .

[0078] Referring to Table 1, Table 1 is the formula of steel silk glue in Examples 1-3 of the present invention.

Abstract

The invention provides steel wire rubber for a tire based on isoprene rubber and a tire rim based on the isoprene rubber. The invention provides steel wire rubber which takes isoprene rubber as a raw rubber main body and uses a small amount of other synthetic rubber. According to the present invention, during the frictioning process of the tire bead steel wire, based on the good stiffness and the low viscosity of the trans-isoprene rubber steel wire rubber, the occurrence of the process problems such as the coating rubber cracking and the copper leakage on the surface of the steel wire during the frictioning can be prevented so as to solve the process problems of the pure isoprene rubber steel wire rubber formula, and the performance of the rubber material is also comparable with that of a natural rubber formula.

Description

technical field [0001] The invention belongs to the technical field of isoprene rubber steel wire glue, and relates to a tire steel ring and an isoprene rubber steel wire glue, in particular to a tire steel wire glue based on isoprene rubber and a tire steel ring based on isoprene rubber. Background technique [0002] The bead is an essential and important part of the tire. It not only plays the role of sealing the gas in the tire, maintaining the tire pressure, but also plays the function of transmitting the load to the tire. The core of the bead is the steel ring and the steel wires that make up the steel ring. The mechanical properties of the steel wire and the structure of the steel ring will directly determine the performance of the bead and even the entire tire. For bias-ply tires, whether the steel ring can fully play its role will also depend heavily on the steel wire glue. The steel wire glue is coated on the surface of a single bead steel wire, and several strands...
