Plant fiber reinforced high-abrasion-resistant tread rubber compound and preparation method thereof

Abstract

The invention discloses a plant fiber reinforced high-abrasion-resistant tread rubber compound and a preparation method of the plant fiber reinforced high-abrasion-resistant tread rubber compound. The compound comprises 100 parts of natural rubber, 55 parts of carbon black, 6 parts of environment-friendly peptizer, 2 parts of stearic acid, 5 parts of zinc oxide, 2 parts of antiager 4010NA, 1.5 parts of preservation wax, 1.5 parts of tackifying resin, 3 parts of aramid staple fiber, 2 parts of adhesive, 5 parts of sulfur, 1.8 parts of accelerant NS, 1 part of shredded ginger fiber, 2 parts of potato fiber, and 1 part of egg shell powder. After the potato fiber is added into the compound, the three-dimensional fiber net-shaped structure tightly entangles the shredded ginger fiber, so that the performance of a rubber product is strengthened on the whole, the potato fiber is wrapped on the shredded ginger fiber, an active free radical of the potato fiber promotes the adhesion with a rubber matrix; a porous egg shell particle in contact with the rubber has a large specific surface area, so that the contact area between the potato fiber and the rubber is increased, and utilizing the wastes like the egg shell is favorable for protecting the environment.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a plant fiber reinforced high wear-resistant tread rubber compound and a preparation method thereof. technical background [0002] As people have more and more requirements for cars, tires have become a very important research object in addition to the interior functions and safety of cars. Tires support the entire weight of the car and bear the load, transmit traction and braking force, and ensure the adhesion between the wheel and the road surface; they can also absorb and slow down the impact and vibration generated by the car during driving, which can not only slow down the vibration of car parts Destroying and improving ride comfort, it can also reduce the noise generated by the car at high speeds, ensuring the safety, stability and comfort of the car. The outermost part of the tire is called the tread. Through a specific pattern, the tire has traction and braking force. At ...
