After the removal ', the processing operation is to complete the rubber vulcanization operation. The material is stripped, and then trimmed to become a finished tire. It is worth noting that when the vulcanizing agent in the rubber reaches the reaction temperature, there is approximately β ^ 0 / * * 0 irreversible vulcanization, and the remaining 1 5% It still remains in the finished rubber product, and these residual vulcanizing agents and some rubbers that have not been vulcanized are a key technical point of the present invention. β In the above-mentioned tire manufacturing process, waste will be generated, and the replacement of old tires will be the largest source of waste. In addition, the production and replacement of other rubber products (such as shoe soles) will continue to increase the amount of rubber waste. In the past, the waste was mainly burned or buried, but there was still pollution (the dioxin was produced by the incineration, S 〇 ···). Therefore, some operators grind the waste into rubber powder. The method disclosed in No. 26652, however, the use of rubber powder is at best only used as a filler. For example, in the formulation of the first figure, the rubber powder is used as a filler to produce low-speed tires and industrial applications. Yuekou, etc., "In the case that the rubber powder has destroyed the cross-linking structure of the original molecule I", its network structure no longer exists, and various physical properties have been lost, and it can only be used early to reduce weight. This rubber The abrasion resistance, elongation and tensile resistance of the product will be deteriorated due to the large amount of filler used, so its amount is quite limited. In view of this, the inventor of this case has carefully considered and accumulated professional experience for many years. Yanjiu's development experience led to the birth of this invention. That is, the main purpose of the present invention is to make the rubber waste into a new rubber material after special treatment, and then make it into a recycled rubber tire, which can not only reduce the new material's 1,11II 11 --- · 1; -J --- ----- ^.
