Anti-pricking and anti-busting scientific and technical safety tire and machining method thereof

Abstract

The invention provides an anti-pricking and anti-busting scientific and technical safety tire and a machining method thereof. The tire structurally comprises a tread rubber layer (1), a buffering layer (2), a steel wire band bundle layer (3), a curtain cloth layer (4), an airtight layer (5) and a polymer synthesis memory sizing material layer (6) in sequence from outside to inside. The thickness of the polymer synthesis memory sizing material layer (6) ranges from 1.5 mm to 20 mm. The tire has the beneficial effects that the polymer synthesis memory sizing material layer is sprayed to the inner surface of the tire, so that the tire is high in strength, stretchability and adhesion, the softening point of the sizing material layer is higher than 150 degrees, the glass transition temperature point of the sizing material layer is lower than -35 degrees, it can be guaranteed that no air leaks from the tire and the tire does not burst when the tire is pricked by foreign matter; spraying is conducted in a free follow-up mode, the evenness of the sizing material spraying effect is guaranteed, and the dynamic balance of the tire is not affected; and the tire can be prevented from being oxidized and polluted by air through an anti-adhesive and anti-pricking sealing protection layer, meanwhile, the anti-pricking and sizing layer shaping capacity is extremely high, ultraviolent rays can be prevented, and the reliability of the product is improved.

Description

technical field [0001] The invention relates to a puncture-proof and explosion-proof technological safety tire and a processing method thereof. Background technique [0002] Tire safety technology, from run-flat tires to tire self-replenishment, to puncture-resistant tires (third generation) sprayed with polymer leak-proof sealing materials, all have corresponding defects. The real name of run-flat tires is run-flat tires or zero tires. Continue to drive the tire under pressure. After the tire is deflated, use the hard tire wall to support the vehicle to continue driving for a certain mileage. , automatically inflates, and repairs nail wounds, but exists in the form of liquid in the tire, the tire will lose its dynamic balance, and the steering wheel will vibrate. In addition, this product is corrosive and has a corrosive effect on the tire and wheel hub. It is an obsolete product. The safety tire upgraded with ordinary hot melt adhesive only has the function of anti-punctu...

AI Technical Summary

Problems solved by technology

[0003] In summary, the prior art has the following disadvantages: 1. The sizing material of the prior art is soft, and the tensile strength and tensile tearing rate are relatively low. When a large tread wound is encountered, the inner coating sizing material is relatively easy Squeeze out from the wound; 2. The temperature range is small, from minus 20 degrees to about 75 degrees, which is not suitable for use in China; 4. After the rubber material of the prior art is sprayed on the tire, there is a high risk of degumming in summer and cracking in winter Risks, affecting the dynamic balance of the vehicle, resulting in hidden dangers to vehicle safety, unable to be industrialized on a large scale
