Embodiment 1

[0032] refer to figure 1 , a production process of anti-puncture tires, comprising the steps of:

[0033] (1) The adhesive is prepared by spraying and shaping to obtain the self-sealing layer film 1; wherein, the adhesive is a combination of polyurethane and EVA hot-melt adhesive, wherein the weight ratio of polyurethane to hot-melt adhesive is 1:0.45, and the self-sealing layer film Forming by spraying and cooling;

[0034] (2) After cleaning the inner surface of the carcass 2, an adhesive is sprayed on the inner surface of the carcass. Pressurize and shape to get the puncture-proof tire; wherein, the lamination between the self-sealing layer film and the inner surface of the carcass is completed by a placement machine, the thickness of the self-sealing layer film 1 is 2.3mm, and the coverage of the self-sealing layer film is the tire tire The whole crown extends to the tire anti-friction line 3 toward the shoulder direction; the adhesive includes the following components: mo...

Embodiment 2

[0052] refer to figure 1 , a production process of anti-puncture tires, comprising the steps of:

[0053] (1) The adhesive is prepared by spraying and shaping to obtain the self-sealing layer film 1; wherein, the adhesive is a combination of polyurethane, polyacrylic resin and polyamide, and the weight ratio of polyurethane, polyacrylic resin and polyamide is 1:0.85 : 0.15;

[0054] (2) After cleaning the inner surface of the carcass 2, an adhesive is sprayed on the inner surface of the carcass. The puncture-resistant tire is obtained by pressurizing and shaping; wherein, the self-sealing layer film and the inner surface of the carcass are bonded by a cold paste process, the thickness of the self-sealing layer film 1 is 2.1mm, and the self-sealing layer film covers the entire crown of the tire. And extend to tire antifriction line 3 toward tire shoulder direction; Described binding agent comprises following component: modified alicyclic amine epoxy resin curing agent, silane...

Embodiment 3

[0056] A kind of production technology of anti-puncture tire, comprises the steps:

[0057] (1) The self-sealing layer film is prepared by spraying and shaping the polyurethane adhesive; the self-sealing layer film is formed by spraying and heating;

[0058] (2) After cleaning the inner surface of the carcass, spray the adhesive on the inner surface of the carcass, after the self-sealing layer film and the inner surface of the carcass are bonded and pasted by adhesive, and then pressurized and shaped.

Abstract

A related production technology for a sticking-resistant tire comprises the following steps: (1) preparing a self-sealing layer film from an adhesive; and (2) applying the self-sealing layer film to the internal surface of the tire body through an adhesive, and performing pressurization fixing to obtain the sticking-resistant tire. According to the production technology, the film is firstly independently formed and then is applied to the internal surface of the tire, and pressurization fixing is performed after applying, so that the tire can be used and vulcanization processing is not needed. The production technology for the sticking-resistant tire is relatively convenient, and has the advantages of being high in production efficiency, relatively low in cost, suitable for industrial production and the like.

Description

technical field [0001] The invention relates to a tire production process, in particular to a puncture-resistant tire production process. 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 dangers of tires. The death rate of tire blowout accidents 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 ac...
