Problems solved by technology

The technical requirements of tire products are relatively high, such as vehicle speed, dynamic balance, temperature, pressure, tire material and other conditions all need to be considered. Under the large temperature difference and long-term bearing pressure, the anti-tie layer will inevitably become old and fall off, resulting in greater safety hazards

Abstract

The invention discloses a puncture-resistant safe tire for a passenger vehicle. The tire comprises an outer tire, a composite layer uniformly distributed along the inner side of the outer tire, and a puncture-resistant elastic lining rubber material layer uniformly distributed on the inner side of the composite layer. The puncture-resistant elastic lining rubber material layer is coated on the composite layer which is arranged on the inner side of the outer tire of the tire for the passenger vehicle, so that the tire has high puncture resistance, durability, leak resistance, high temperature resistance and bonding property.

Description

technical field [0001] The invention relates to a tire for passenger vehicles, in particular to a puncture-resistant safety tire for passenger vehicles. Background technique [0002] Among numerous traffic accidents, the traffic accidents caused by tire blowout account for 20%. According to statistics, 46% of traffic accidents on highways are caused by tire failures, among which puncture accounts for 70% of the total amount of accidents. According to data, more than 10,000 people die in traffic accidents caused by car tire blowouts in China every year. Among the above-mentioned tire blowout accidents, except for the tire blowout caused by unreasonable tire pressure, a large part of the reason comes from the fact that the tires are on unclean roads. Caused by penetration of foreign objects. In order to alleviate the hidden dangers of accidents caused by the above problems, at present, those skilled in the art have tried hard in this regard. For example, Chinese utility mode...
