Embodiment 1-4

[0066] The preparation of embodiment 1-4 rubber composition follows the steps:

[0067] This process uses a series type one-time method internal mixer, controls the rotor speed of the internal mixer to 50rpm, and the pressure on the top bolt is 55N / cm 2 , The cooling water temperature of the internal mixer is 30~40°C.

[0068] Upper auxiliary machine process:

[0069] 1. Add rubber, carbon black, inorganic filler, zinc oxide, stearic acid, anti-aging agent, microcrystalline wax, press the top bolt to raise the temperature of the rubber to 100°C;

[0070] 2. Raise the top bolt to add naphthenic oil and keep it for 5 seconds;

[0071] 3. Press the top bolt to raise the temperature of the rubber to 140°C;

[0072] 4. Press the top bolt to make the rubber mix at a constant temperature of 150 ° C ~ 155 ° C for 120 seconds;

[0073] 5. Discharge the rubber material to the lower auxiliary machine.

[0074] Lower auxiliary machine process:

[0075] 1. Raise the temperature of th...

Abstract

The invention belongs to the field of rubber tire manufacturing and relates to a rubber composition capable of effectively lowering tire smell grade. The rubber composition comprises, by weight, 90.0-100.0 parts of edible-grade butyl rubber, 30.0-80.0 parts of carbon black, 0-50.0 parts of softening oil, 0.5-4.0 parts of protective wax, 0.5-4.0 parts of antiager, 1.0-3.5 parts of sulfur and 0.3-2.5 parts of promoter. The rubber composition can effectively lower tire smell grade and is suitable for manufacturing low-smell tires, especially standby tires. Physical and mechanical performance of the rubber composition and high speed and durability of the tires can meet normal using requirements.

Description

technical field [0001] The invention belongs to the field of rubber tire manufacture, and relates to a rubber composition capable of effectively reducing the tire odor level, which is suitable for the manufacture of low-odor tires, especially spare tires. Background technique [0002] Generally, cars will have spare tires (hereinafter referred to as spare tires). The function of spare tires is to temporarily replace damaged tires so that the car can continue to drive. Depending on the model, the spare tire is usually placed under the trunk floor, hung under the rear of the car or fixed outside the trunk door. When the spare tire is placed under the trunk floor, its own odor cannot be transmitted to the outside of the vehicle, so the size of its odor has a great impact on the odor level inside the vehicle. [0003] Spare tires are generally used suddenly after long-term storage. In order to ensure safe driving after replacing the spare tire, the rubber composition design of ...
