Embodiment 1

[0018] This embodiment proposes a bias tire for cars, including a bias tire body composed of a tread, a carcass, a buffer layer, and a bead. The rubber composition prepared by using agent, accelerator, vulcanizing agent, vulcanization accelerator and adhesion promoter. Among them, the rubber includes perfluoroether rubber, nitrile rubber and natural rubber, and the rubber accounts for 50% of the total tread rubber.

Embodiment 2

[0020] This embodiment proposes a bias tire for cars, including a bias tire body composed of a tread, a carcass, a buffer layer, and a bead. The rubber composition prepared by using agent, accelerator, vulcanizing agent, vulcanization accelerator and adhesion promoter. Among them, rubber includes perfluoroether rubber, nitrile rubber and natural rubber, and the ratio of rubber to the total tread rubber is 54.5%.

Embodiment 3

[0022] This embodiment proposes a bias tire for cars, including a bias tire body composed of a tread, a carcass, a buffer layer, and a bead. The rubber composition prepared by using agent, accelerator, vulcanizing agent, vulcanization accelerator and adhesion promoter. Among them, the rubber includes perfluoroether rubber, nitrile rubber and natural rubber.

Abstract

The invention discloses a diagonal tire for a sedan car. The diagonal tire comprises a diagonal tire body composed of a tire tread, a tire body, a buffering layer and a tire bead, wherein rubber is used as a base body and supplemented with reinforcing filler, accelerant, vulcanizer, vulcanization accelerator and adhesion promoter to prepare a rubber composition serving as the tire tread, and rubber includes fluoroether rubber, butadiene-acrylonitrile rubber and natural rubber. The diagonal tire tread manufactured from the rubber base body composed of fluoroether rubber, butadiene-acrylonitrile rubber and natural rubber is adopted, compared with a tire tread mainl manufactured from solution polymerized styrene-butadiene rubber, high temperature resistance and deformation resistance of fluoroether rubber are reserved, the diagonal tire is suitable for the sedan car and capable of meeting requirement for different driving environments of people, and the service life of the tire can be prolonged.

Description

technical field [0001] The invention relates to a bias tire for a car, in particular to a compound formula for a bias tire for a car, and belongs to the field of polymer materials. Background technique [0002] Radial tires are a structural form of tires in which the carcass uses rayon or other fibers and the belt layer uses steel cords. It is different from bias tires, arched tires, and pressure-regulated tires. This type of radial tire is called semi- Steel radial tires. Due to the characteristics of strong grip, good braking performance, large bearing capacity, and good comfort, more and more cars or light trucks choose this type of radial tire. However, due to high manufacturing technology requirements and high cost, and most low-profile cars use ordinary bias tires, in order to match the use of bias tires and meet people's different requirements for driving environments, the improvement of tire performance has been put on the agenda. We know that the performance of th...
