Problems solved by technology

Usually, the amount of white carbon black in the base rubber is very large, which makes it difficult to process the rubber material; therefore, in the process of processing, it is easy to cause the instability of the manufacturing process, which will further lead to uneven physical properties of the rubber material, and then make the material The extrusion and calendering process changes greatly; therefore, during the vulcanization process of the radial tire, due to the melting of the rubber material and the pressure of the vulcanization bladder, the base rubber will penetrate into the tread rubber, resulting in uneven material distribution and affecting Durability of radial tires

Embodiment 1

[0019] The embodiment of the present invention provides a kind of preparation method of radial tire, such as figure 1 shown, including the following steps:

[0020] Step 101: sending the base glue into the radiation chamber of the electron radiation device, and the electron accelerator in the electron radiation device can emit electron beams into the radiation chamber;

[0021] Step 102: controlling the electron accelerator to emit an electron beam to the base glue, the energy of the electron beam is 0.5 MeV, the beam intensity is 0-100mA, the passing speed is 0.5-10m / min, and the radiation dose is 0kGy-40kGy; the pressure in the radiation chamber is one atmosphere, the temperature is 0-100°C, and the radiation atmosphere is an air atmosphere or an inert gas atmosphere; here, after the treatment in this step, a modified base glue is obtained. Here, MeV is megaelectron volts, which is equal to the energy obtained by an electron when it is accelerated at a voltage of one megavo...

Abstract

The invention discloses a preparation method of a radial tire. The preparation method comprises the following steps that: base rubber is fed into a radiation chamber of an electron radiation device, and an electron accelerator in the electron radiation device can emit electron beams into the radiation chamber; the electron accelerator is controlled to emit a primary electron beam to the base rubber, the energy of the electron beam is 0.5 MeV, the beam intensity is 0-100 mA, the passing speed is 0.5-10 m / min, and the radiation dose is 0-40 kGy; the pressure in the radiation chamber is 101.325kPa, the temperature is 0-100 DEG C, and the radiation atmosphere is air atmosphere or inert gas atmosphere; and the radial tire comprising the base rubber is produced. In conclusion, the radial tire prepared by the method has the advantage of high durability.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a preparation method of a radial tire. Background technique [0002] Radial tire is a commonly used tire. Compared with other tires, it has the following advantages: (1) Large ground contact area, good adhesion performance, small tread slippage, and small unit pressure on the ground, so the rolling resistance is small and the service life is long. Long; (2) The crown is thick and has a hard belt layer, which is not easy to puncture; the deformation is small during driving, which can reduce fuel consumption by 3% to 8%; (3) Because the number of plies is small and the sidewall is thin, its Large radial elasticity, good cushioning performance, and large load capacity; (4) Good heat dissipation performance, which can adapt to high temperature and high speed driving. So as to obtain more and more extensive applications. [0003] A base rubber is provided between the tread and the bel...
