The invention relates to the technical field of tires, in particular to a self-sealing tire and a preparation process thereof.The self-sealing tire comprises a tire body and a preparation device, and the tire body sequentially comprises high-strength wear-resistant rubber, a connecting layer, a coating layer, a buffer layer, a leakage-proof sealing layer and an airtight layer from outside to inside. According to the spraying device, when liquid leakage-proof sealing and repairing colloid is sprayed, the phenomenon that the two sides of a coating are thin and the middle of the coating is thick can be avoided, the leakage-proof effect is ensured, the sprayed colloid can be preliminarily dried while spraying is conducted, the flowing phenomenon of the sealing and repairing colloid during follow-up tire moving is reduced, and the phenomenon of uneven distribution is reduced.

    本发明涉及轮胎技术领域,尤其为一种自密封轮胎及其制备工艺,包括轮胎和制备装置,所述轮胎由外向内依次为高强度耐磨橡胶、连接层、包覆层、缓冲层、防漏密补层和气密层。本发明可以在对液态的防漏密补胶体进行喷涂时,可以避免出现涂层两侧薄中间厚的现象,确保防漏效果,并且在喷涂的同时可以对喷涂的胶体进行初步的烘干,降低后续移动轮胎时,密补胶体出现流动现象,降低分布不均匀的现象。
