The invention provides a pneumatic tire and an anti-puncture method of the pneumatic tire. The pneumatic tire comprises a tread layer and a reinforcing layer, the outer side of the tread layer is provided with a plurality of pattern grooves, the pneumatic tire further comprises a sealing layer covering the inner side of the reinforcing layer, the sealing layer is made of a self-sealing rubber composition, the sealing layer comprises a reinforced sealing structure, and the reinforced sealing structure completely covers the position, corresponding to the pattern groove, of the inner side of the reinforcing layer. By adopting the structure, when a sharp object punctures from the bottom of the pattern groove to the inside of the pneumatic tire, the reinforced sealing structure corresponding to the pattern groove can cover the surface of the sharp object, so that the air pressure inside the pneumatic tire is prevented from leaking; and when the sharp object is pulled out of or removed from the pneumatic tire, the sealing layer on the periphery of the reinforcing sealing structure and the puncture hole can flow into the puncture hole, the pneumatic tire is kept sealed, air pressure in the pneumatic tire is prevented from leaking, and the pneumatic tire is effectively prevented from being punctured and damaged by the sharp object.
本发明提供一种充气轮胎和充气轮胎防穿刺方法,所述充气轮胎包括胎面层和加固层,所述胎面层外侧设置有若干花纹沟,所述充气轮胎还包括覆盖于所述加固层内侧的密封层,所述密封层的材质为自密封橡胶组合物,所述密封层包括加强密封结构,所述加强密封结构完全覆盖在所述加固层内侧与所述花纹沟相对应的位置。采用如上结构,当尖锐物件从花纹沟底部向充气轮胎内部穿刺时,与该花纹沟相对应的加强密封结构能够包覆于尖锐物件的表面,防止充气轮胎内部的气压泄漏;当尖锐物件从充气轮胎拔出或去除时,加强密封结构及穿刺孔周边的密封层能够流入穿刺孔,并使充气轮胎保持密封,防止充气轮胎内部的气压泄漏,有效防止充气轮胎被尖锐物件穿刺破坏。
