Preparation process of damping tire

Abstract

The invention discloses a preparation process of damping tire. An outer tire body is independently formed and then matched with an elastic body, a mold matched with a cavity and an annular opening is arranged on an outer tire forming mold when the outer tire body is prepared, the mold is detached after the outer tire body is prepared, the cavity and the annular opening are formed, an elastomer is subsequently and independently prepared and then assembled with the outer tire body, or the elastomer is directly formed in the outer tire body through a foaming material, the technological process is simple, and the technological cost is low; and the damping tire is prepared from rubber and the TPE which are low in cost, the cost is low on the basis of excellent damping and noise-reducing effects, and the anti-slip performance is excellent.

Description

technical field [0001] The invention relates to a tire preparation process, in particular to a shock-absorbing tire preparation process. Background technique [0002] The tires used by traditional scooter or skateboard etc. usually comprise wheel hub and the cover tire that is fixed on the wheel hub. Traditional cover tire mainly contains two kinds, and the first kind is pneumatic cover tire, and the second kind is solid cover tire. Wherein, the inside of the pneumatic tire is provided with an inflation cavity, which is light in weight, and the inner cavity of the pneumatic tire and the inflated body have a buffering effect during driving, and the shock absorption effect is better. But the air-filled cover tire needs to be inflated frequently to ensure its normal operation, which is inconvenient to use, and when the speed of the scooter or skateboard is fast, the gas in the pneumatic cover tire is heated and expands, which is easy to burst the tire and is less safe. There ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned tires have better shock-absorbing and noise-reducing effects, and are more comfortable and safe, they are limited by the connection and matching relationship among the wheel hub, the outer tire and the shock-absorbing and noise-reducing ring, so the preparation process is relatively complicated, and its The tire is made of PU material through the infusion process

However, the current conventional rubber material and TPE material for preparing the outer tire cannot be applied to the pouring process. Compared with rubber material and TPE material, PU material not only has a higher price, but also has lower skid resistance than rubber material and TPE material. Therefore, the above tire Not only the cost is still high, but also its anti-skid performance needs to be improved
