Abstract
The invention belongs to the technical field of tires, in particular to white sidewall rubber of a radial tire of a passenger car. The white sidewall rubber of the radial tire of the passenger car comprises raw materials in parts by weight as follows: natural rubber, ethylene propylene diene monomer rubber, butadiene styrene rubber, zinc oxide, zinc stearate, white carbon black, ultramarine, magnesium oxide and sulfur. The white sidewall rubber is wear-resistant, aging-resistant, puncture-resistant and resistant to dryness, wetness and skid and has lower hysteresis loss.
Description
Technical field
The invention belongs to the technical field of tire, be specifically related to a kind of white sidewall rubber of radial tyre of passenger car.
Background technology
Half-steel meridian tyre refers to that body cord and crown center are 90 ° of angles or approaches that 90 ° of angles are arranged and with the pneumatic tyre of belt banding carcass.The fetus face bit position of half-steel meridian tyre or all adopt steel wire cord as supporting material, carcass adopts the radial of the filamentary materials such as nylon, polyester.Car half-steel meridian tyre comprises that tyre surface, band, belt, sidewall, the wear-resisting glue in rim of the mouth, carcass, air retaining wall, tyre bead, triangle rubber, rim of the mouth protect cloth.Car half-steel meridian tyre constructional feature is the single sizing material of the general employing of tyre surface, can not do hierarchial design; On belt, increase by one to two-layer fiber band, improve tire high speed performance; Sidewall is soft, and warping strength fatigability and anti-light aging performance are good; Tubeless design, air retaining wall requires to have extremely low ventilation property; For improving the rigidity of bead region, adopt large and hard triangle rubber stamen.
Car half-steel meridian tyre has following characteristics: 1, at a high speed; 2, fuel-economizing; 3, wear-resisting; 4, ride comfort; 5. handle
Stable; 6, low noise.
When the travel speed of tire is high, the wriggling between tyre surface and ground is very little, and tractive force and side force are higher, therefore requires tread rubber will have higher hardness, wear resistance, traction property, lower rolling resistance preferably.
Summary of the invention
