Problems solved by technology

[0003] Conventional car tire steel wire rubber is mainly biased towards high hardness, usually supported by the high hardness of the rubber material itself, special care must be taken when the bead is stressed when installing the tire, and it is prone to permanent deformation; at the same time, the cooperation between the bead and the hub needs to be very careful. Appropriate, if the matching degree is slightly poor, it will be difficult to install the tire, and the hard tire will easily cause carcass damage; on the other hand, the conventional car tire steel wire glue and steel wire have average viscosity, and it is easy to delaminate and separate after a long time

Abstract

The invention discloses high-performance automobile tire wire rubber. The high-performance automobile tire wire rubber comprises (by weight): 20-23% of natural rubber, 17-23% of styrene butadiene rubber SBR 1502, 35-40% of universal furnace black, 7-9% of processing oil, 0.6-1.0% of an active agent ZnO, 3-5% of an active agent SA, 1.5-2.0% of a tackifier WS-27, 1.5-2.0% of a tackifier 1102, 1.5-2.0% of a tackifier HRJ10420, 1.0-3.0% of a vulcanizing agent OT-20, 1.0-2.0% of a vulcanizing agent CLS-B, 0.3-0.8% of an accelerator NS and 0.06-0.1% of a scorch retarder, wherein the sum of the contents of the components is 100%. The invention further provides a preparation method of the high-performance automobile tire wire rubber; in this way, the adaptability of the prepared product to a hub is higher during tire mounting, the shape of a tire bead can be well recovered after the tire bead is stressed, meanwhile, the bonding viscosity of the tire bead and a steel wire is effectively improved, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a high-performance automobile tire steel wire rubber and a preparation method thereof. Background technique [0002] In recent years, China has developed into the world's largest tire producer and also the world's largest tire market; however, the lack of core tire technology in my country has not changed with the expansion of the industry scale and market and the improvement of manufacturing technology. Therefore, vigorously developing new technology and new formula is the only way to realize the transformation of my country from a big tire manufacturing country to a tire powerful country. [0003] Conventional car tire steel wire rubber is mainly biased towards high hardness, usually supported by the high hardness of the rubber material itself, special care must be taken when the bead is stressed when installing the tire, and it is prone to permanent deformation; at the ...
