Embodiment 1

[0044] refer to figure 2 , a puncture-resistant tire, which is provided with an airtight layer 4, a carcass layer 2, a belt layer 5 and a tread 1 in sequence from the inside to the outside, and a rubber layer is arranged between the airtight layer 4 and the carcass layer 2 The self-sealing layer 3, the rubber self-sealing layer 3 is fully covered on the carcass layer 2. The thickness of the rubber self-sealing layer is 0.5mm, and the thickness of the airtight layer is 2.2mm; the ply is a steel ply, and the number of layers of the steel ply is 3 layers.

[0045] The rubber self-sealing layer 3 is prepared from polyacrylic resin and polyurethane adhesive in a weight ratio of 1:0.98. Polyurethane has good physical and mechanical properties, excellent cold resistance, elasticity, high gloss, and softness and hardness do not change much with temperature, and is resistant to organic solvents. However, polyurethane resin coating has poor water resistance and mechanical strength is ...

Embodiment 2

[0056] refer to image 3 , a puncture-resistant tire, which is provided with an airtight layer 4, a carcass layer 2, a belt layer 5 and a tread 1 in sequence from the inside to the outside, and a rubber layer is arranged between the airtight layer 4 and the carcass layer 2 The self-sealing layer 3 , the rubber self-sealing layer 3 partially covers the carcass layer 2 . The thickness of the rubber self-sealing layer is 1.2mm, and the thickness of the airtight layer is 1.2mm. The cord layer is a steel cord layer, and the number of layers of the steel cord layer is 5 layers.

[0057] The rubber self-sealing layer 3 is prepared from polyurethane, polyamide and EVA hot-melt adhesives with a weight ratio of 1:0.9:0.25. The compounded rubber self-sealing layer material has excellent initial adhesion, holding strength and resilience. The airtight layer is prepared with bromobutyl rubber as the main body, adding carbon black, silicon dioxide, aluminum, rubber dispersant, and sulfur,...

Embodiment 3

[0068] refer to figure 2 , a puncture-resistant tire, which is provided with an airtight layer 4, a carcass layer 2, a belt layer 5 and a tread 1 in sequence from the inside to the outside, and a rubber layer is arranged between the airtight layer 4 and the carcass layer 2 The self-sealing layer 3, the rubber self-sealing layer 3 is fully covered on the carcass layer 2. The thickness of the rubber self-sealing layer is 1.8mm, and the thickness of the airtight layer is 0.9mm. The cord layer is a steel cord layer, and the number of layers of the steel cord layer is 3 layers.

[0069] The rubber self-sealing layer 3 is prepared from polyacrylic resin adhesive. The airtight layer is mainly made of bromobutyl rubber, and prepared by adding white carbon black, mica, rubber dispersant, and sulfur, wherein the weight ratio of bromobutyl rubber, white carbon black, mica, rubber dispersant, and sulfur is 1:0.3:2.1:0.03:0.02.

[0070] The anti-puncture tire is prepared by the follow...

Abstract

The invention relates to an anti-puncturing tyre and a preparation method of the anti-puncturing tyre. The anti-puncturing tyre is sequentially provided with an air-tight layer, a curtain cloth layer, a belted layer and a tread from inside to outside, wherein a rubber self-sealing layer is arranged between the air-tight layer and the curtain cloth layer; the rubber self-sealing layer is composed of more than one layer of rubber sheets by an adhesive. The thickness of the rubber self-sealing layer is 0.2mm-5.0mm and the thickness of the air-tight layer is 0.5mm-3.0mm. The anti-puncturing tyre is simple in structure and reasonable in design and has the characteristics of high production efficiency, low cost, good anti-puncturing effect, high safety performance and the like.

Description

technical field [0001] The invention relates to a tire, in particular to a puncture-resistant tire and a preparation method thereof. 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 ...
