Abstract

The invention relates to a preparation method of a safe anti-puncturing tyre. The safe anti-puncturing tyre is sequentially provided with a self-sealing layer, an air-tight layer, a curtain cloth layer, a belted layer and a tread from inside to outside. The preparation method comprises the following steps: (1) extruding the tread by using an extruding machine; (2) spraying and molding an adhesive to form the self-sealing layer; (3) respectively pressing the air-tight layer and the curtain cloth layer by a calendering machine; (4) molding the belted layer; and (5) fitting the self-sealing layer, the air-tight layer, the curtain cloth layer, the belted layer and the tread on a molding machine and integrally molding and fitting to obtain the safe anti-puncturing tyre. The tyre prepared by the preparation method provided by the invention is simple in structure and reasonable in design and has the characteristics of high production efficiency, low cost, good tyre anti-puncturing effect, high safety performance and the like.

Description

technical field [0001] The invention relates to a tire, in particular to a preparation method of a safe puncture-proof tire. Background technique [0002] With the rapid development of the automobile industry and the improvement of the traffic road network, improving the performance of motor vehicle tires and developing safe, durable, high-speed and low-cost products have become one of the important research projects of the current scientific research and production departments. According to incomplete statistics from relevant professional organizations, more than 95% of automobile tires have potential safety hazards, 60% of tires have abnormal tire pressure, and 70% of traffic accidents on domestic expressways are caused by hidden tire hazards. The death rate of a tire blowout accident is as high as 100%. High-speed tire blowout, speeding driving, fatigue driving, and drunk driving have become the four major culprits of vehicle safety accidents. Traffic accidents are shoc...
