Problems solved by technology

During the driving process of the vehicle, the contact area between the tire and the ground is large, which is conducive to gripping and braking, but it is not conducive to reducing the resistance of the tire; on the contrary, if the contact area between the tire and the ground is small, although it is beneficial to reduce the resistance of the tire, it is not conducive to reducing the resistance of the tire. grip and braking
It can be seen that the existing tires cannot dynamically change the contact area between the tire and the ground
At present, the characteristics of this kind of tire come from the characteristics of rubber. Rubber is an elastic body, and its internal stress deformation is proportional to the applied stress. Its internal deformation cannot change with the change of rolling speed. The deformation of tread rubber is mainly It is related to tire pressure, so often this deformation cannot be changed dynamically

Abstract

The invention discloses a manufacturing method for an anti-ageing and shearing hardening type rubber composite for tires. The manufacturing method specifically comprises the following steps that firstly, a rubber mixture is added into a rubber open mill with an existing open technology; secondly, a rubber foaming agent is added into the mixture obtained in the first step; thirdly, a shearing thickening material is added into the mixture obtained in the second step; fourthly, the mixture obtained in the third step is extruded with a screw extruder for forming, and the anti-ageing and shearing hardening type rubber composite can be obtained. When tires rotate at a lower speed, the shearing thickening material in the rubber / shearing thickening composite can flow and deform, the rubber / shearing thickening composite is greatly deformed and becomes soft, and thus the group holding force of tires is enlarged; on the contrary, when tires rotate quickly, the rolling resistance of tires can be reduced; by adding flaky nanometer carbon black, the space sealing effect of rubber molecules can be improved, slow corrosion of ozone and ultraviolet can be well blocked, and the anti-ageing performance of rubber can be improved.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of rubber materials, in particular to a method for producing an aging-resistant and shear-hardened rubber composite material for tires. Background technique [0002] At present, the contact area between the tire and the ground is mainly regulated by the air pressure inside the tire. If the air pressure in the tire is high, the contact area between the tire and the ground is small. When the air pressure in the tire decreases, the contact area between the tire and the ground increases. During the driving process of the vehicle, the contact area between the tire and the ground is large, which is conducive to gripping and braking, but it is not conducive to reducing the resistance of the tire; on the contrary, if the contact area between the tire and the ground is small, although it is beneficial to reduce the resistance of the tire, it is not conducive to reducing the resistance of ...
