Problems solved by technology

When the tire is punctured, the internal viscous material will wrap the punctured object to prevent air leakage. When the punctured object is pulled out, the rubber material will instantly fill the formed gap, thereby realizing the function of automatic repair. Improve the safety of the tire, but this method needs to fill a large amount of rubber into the tire, and the performance of the rubber stored inside the tire will change with the change of the tire temperature, thus affecting the self-repair effect of the tire and the repair time. stability

preparation example Construction

[0042] A preparation process with self-repairing safety tires, the process is applicable to the above-mentioned tires, the steps are as follows:

[0043] S1: Firstly, mix A base material sheet and B base material sheet respectively with a reaction kettle kneader according to the formula, and then extrude through a screw extruder to form A base material and B base material with a thickness of 1-2 mm and a width equal to the tire width Roll material, and sandwich PET film between the two to form a combination of A substrate sheet, PET film and B substrate sheet, and the upper and lower sides of the combination are covered by release paper;

[0044] S2: Then on the forming machine, base C base material on the drum first, then attach the combination of A base material sheet, PET film and B base material sheet in sequence, repeat three times, attach three layers, and then attach them in sequence Buffer layer, transition layer, steel wire layer, cord fabric layer and tread compound;...

Embodiment approach

[0048] As an embodiment of the present invention, the cross-sectional shapes of the sliding chamber 5 and the limiting plate 10 are ring shapes respectively, and the outer end of the side wall of the sliding plate 6 is installed with a power block 15 communicating with the discharge groove 13 , the side wall of the power block 15 is provided with a nozzle 16 tangent to the side wall of the slide plate 6, and the bottom end of the slide plate 6 is rotatably connected with a bottom plate 17; when working, when the electric spray box 12 squeezes the repair glue inside At this time, a part of the repair glue can be ejected from the nozzle 16 and be tangent to the side wall of the slide plate 6, so that the repair glue can apply a rotating force to the slide plate 6 during the ejection process. At this time, the slide plate 6 is relatively When the bottom plate 17 rotates, it can drive the nozzle 14 to rotate and spray glue on the damaged position of the carcass 2, which further imp...

Abstract

The invention belongs to the technical field of tire preparation, and particularly relates to a preparation process of a self-repairing safety tire. The tire comprises a hub and a tire body, the hub is provided with a self-repairing device, the self-repairing device comprises a rotating ring, the side wall of the rotating ring is connected with a sliding cavity, the interior of the sliding cavity is connected with a sliding plate in a sliding manner, an electromagnet is installed at the inner end of the sliding plate, a repairing cavity is formed at the outer end of the sliding plate, an electric spraying box is installed in the repairing cavity, repairing glue is stored in the electric spraying box, a discharging groove is formed in the side wall of the repairing cavity, inclined nozzles are arranged on the side wall of the repairing cavity, and magnetic iron is connected to the outer end of the sliding plate. The self-repairing device is arranged in the tire, so that fixed-point and efficient repairing can be realized when foreign matter is punctured into the tire body, the interior of the tire does not leak air, meanwhile, the situation of tire burst can be reduced, the use quality of the tire is improved, and the service life of the tire is prolonged.

Description

technical field [0001] The invention belongs to the technical field of tire preparation, in particular to a preparation and process of a self-repairing safety tire. Background technique [0002] The current tire industry market is relatively large, and the competition is also relatively large. People in the tire industry are constantly looking for new ways out, such as self-repairing safety tires, the general self-repairing tires have a layer of special coating rubber inside. When the tire is punctured, the internal viscous material will wrap the punctured object to prevent air leakage. When the punctured object is pulled out, the rubber material will instantly fill the formed gap, thereby realizing the function of automatic repair. Improve the safety of the tire, but this method needs to fill a large amount of rubber into the tire, and the performance of the rubber stored inside the tire will change with the change of the tire temperature, thus affecting the self-repair ef...
