The invention discloses a co-extrusion self-repairing tire which comprises a tire body layer, an inner tire layer, a butyl rubber inner tire, an outer tire layer and a tire tread layer, the inner tire layer is fixedly arranged on the inner wall of the tire body layer, the butyl rubber inner tire is fixedly arranged in the middle of the outer wall of the tire body layer, the outer tire layer is fixedly arranged on one side of the butyl rubber inner tire, and the tire tread layer is fixedly arranged on one side of the butyl rubber inner tire. A butyl rubber inner tube semi-finished product part containing butyl rubber is extruded through an extruder, then tire materials are sequentially added to extrude the tire body layer, the inner tire layer, the outer tire layer, the tire tread layer, a belted layer and a rubber layer, the semi-finished tire is put into a vulcanization mold, a vulcanization liner filled with high-pressure hot water extrudes the rubber in the mold, so that the butyl rubber inner tire layer with an automatic repairing function is mounted on the inner wall of the tire, the tire has the automatic repairing function when being punctured, the practicability of the tire body is improved, and the service life of the tire is prolonged.

    本发明公开了一种共挤的自补轮胎及其生产工艺,包括胎体层、内胎层、丁基胶内胎、外胎层和胎面层,胎体层的内壁固定设有内胎层,胎体层外壁的中间位置固定设有丁基胶内胎,丁基胶内胎的一侧固定设有外胎层,外胎层的一侧固定设有胎面层,本发明通过挤出机挤出包含有丁基胶的丁基胶内胎半成品部件,再依次添加轮胎材料挤压出胎体层、内胎层、外胎层、胎面层、带束层和橡胶层,将半成品的轮胎放入到硫化模具中,充满高压热水的硫化胆将橡胶挤压在模具中,从而在轮胎的内壁安装一层有自动修复功能的丁基胶内胎层,使得轮胎在被扎破时有自动修复的功能,增加轮胎体的实用性,增加轮胎的使用寿命。
