A kind of puncture leak-proof safety tire for air protection

Abstract

The invention relates to a puncture preventing and air leakage preventing run-flat tire which comprises a tire casing, wherein the run-flat tire is prepared by adopting the following process: (1), preparing liquid adhesive; (2), carrying out atomizing spraying; using a spraying machine to evenly spray the adhesive on the inner surface of the tire casing treated through cleaning; (3), heating, drying and shaping the coating;(4), repeating the steps (2) and (3) in a circulating manner for times until a tire internal coating with the thickness of 0.2 to 10 mm is formed. The puncture preventing and air leakage preventing run-flat tire provided by the invention is characterized in that traffic accidents caused by tire burst and the like can be effectively reduced, and the driving safety is improved; the functions of tire replacement free and tire repair free are achieved, and the driving efficiency is improved; the airtightness of the tire is improved; dynamic balance deviation is reduced, the running resistance of the tire is reduced, and consumption reduction and oil saving can be achieved; the temperature adaptability is superstrong; the high speed carefree driving is achieved; tire noise is reduced during the driving; abrasion is alleviated, and the service life of the tire is prolonged.

Description

technical field [0001] The invention relates to a tire, in particular to a puncture and anti-leakage safety 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, more than 37% of tire crowns have nails or stab wounds, and 70% of traffic accidents on domestic expressways are caused by tires. Caused by hidden dangers, the death rate of a tire blowout accident is as high as 100% when the automobile travels above the speed of 120km / h. High-speed tire blowout, speeding driving, fatigue driving...

Problems solved by technology

Although this structural tire can guarantee a certain safety performance, its weight increases significantly, the manufacturing process is more cumbersome, and the manufacturing cost is higher.

[0005] Although existing safety tires have technically improved to a certain extent, from the perspective of technical performance, there are mainly the following defects: (1) the uniformity of coating thickness cannot be guaranteed, and the thickness of the coating edge and the middle part are different. Even; the existing technology often uses centrifugal force to distribute the coating on the inner surface of the tire, refer to figure 1 , the inner surface of the carcass 1 of the tire is provided with a coating 2. This process can easily cause the phenomenon that the middle is thick and the sides are thin; sometimes the middle thickness has reached 10-15mm, while the thickness of the two sides is only 1-2mm; (2) The temperature resistance adaptability of the coating is limited, the applicable temperature range is small, and the application is limited by the region; (3) The unevenness of the coating leads to poor dynamic balance of the car body, poor noise reduction, and poor comfort Poor; (4) large amount of glue used, thick coating, poor heat dissipation; (5) poor adhesion of the inner coating of the tire, relatively short service life of the tire, unable to meet the needs of high-speed driving of vehicles; (6) narrow application range , the product specifications are limited and cannot meet the needs of various users
