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 the existing safety tires have been improved technically, they still have the following defects in terms of technical performance: (1) The uniformity of the coating thickness cannot be guaranteed; the existing technology often uses centrifugal force to make The coating is distributed on the inner surface of the tire, cf. figure 1 , the coating 2 is provided on the inner surface of the carcass 1 of the tire. This process can easily cause the phenomenon that the middle of the coating is thick and the two sides are thin; usually the middle thickness has reached 10-15mm, while the thickness of the two sides is only 1-2mm; (2) The temperature resistance and 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) Poor heat dissipation; (5) Poor adhesion of tire inner coating, relatively short tire service life, unable to meet the needs of high-speed driving; (6) Narrow application range, limited product specifications, unable to meet various class user needs

Embodiment 1

[0052] refer to Figure 2-5 , a puncture-resistant safety tire, comprising a tire carcass 3, the inner surface of the carcass 3 is evenly provided with a layer of adhesive inner coating 4, the thickness of the inner coating 4 is 3.5mm; the adhesive is polyurethane adhesive. The setting range of the inner coating 4 is the entire tire crown and extends to the first anti-scratch line 5 of the tire in the direction of the shoulder.

[0053] The manufacturing method of the anti-puncture safety tire comprises the following steps:

[0054] (1) Heat and melt the polyurethane hot melt adhesive;

[0055] (2) Install the tire carcass 3 in the rigid cylindrical mold 6, the inner diameter of the rigid cylindrical mold is 83% of the outer diameter of the tire carcass; assemble the tire carcass 3 with the rigid cylindrical mold 6 through a certain mechanism Together, after the tire is installed, the section width of the tire increases, the outer diameter of the tire decreases, the curvatu...

Embodiment 2

[0069] refer to Figure 2-5 , a puncture-resistant safety tire, comprising a tire carcass 3, the inner surface of the carcass 3 is evenly provided with a layer of adhesive inner coating 4, the thickness of the inner coating 4 is 2.5mm; the adhesive is polyurethane Adhesive in combination with ethylene-ethyl acrylate copolymer.

[0070] The manufacturing method of the anti-puncture safety tire comprises the following steps:

[0071] (1) Heat and melt the polyurethane adhesive and ethylene-ethyl acrylate copolymer mixed adhesive with a weight ratio of 1:0.7;

[0072] (2) Install the tire carcass 3 in the rigid cylinder mold 6, the inner diameter of the rigid cylinder mold is 91% of the outer diameter of the tire carcass; The surface curvature is reduced, and the tire running surface is flatter, which is beneficial to improve the uniformity of the hot melt adhesive coating material processing;

[0073] (3) Use a spraying machine to spray the molten mixed adhesive on the inner ...

Embodiment 3

[0086] refer to Figure 2-5 , a puncture-resistant safety tire, comprising a tire carcass 3, the inner surface of the carcass 3 is evenly provided with a layer of adhesive inner coating 4, the thickness of the inner coating 4 is 0.5mm; the adhesive is poly A combination of amides and polyesters.

[0087] The manufacturing method of the anti-puncture safety tire comprises the following steps:

[0088] (1) Heat and melt the mixed adhesive of polyamide and polyester with a weight ratio of 1:1.4;

[0089] (2) Install the tire carcass in the rigid cylinder mold, the inner diameter of the rigid cylinder mold is 76% of the outer diameter of the tire carcass; after the tire is installed, the section width of the tire increases, the outer diameter of the tire decreases, and the radian of the driving surface Reduced, the tire running surface is flatter, which is beneficial to improve the uniformity of hot melt adhesive coating material processing;

[0090] (3) Use a spraying machine ...

Abstract

The invention relates to an anti-puncturing safe tyre, which comprises a tyre body, and is manufactured according to the following process steps: (1) heating and smelting hot-melt adhesive; (2) mounting the tyre body in a rigid cylindrical mold of which inner diameter is less than the external diameter of the tyre body; (3) utilizing a sprayer to spray the smelted hot-melt adhesieve onto the inner surface of the cleaned tyre body; (4) cooling and shaping; (5) circulating the steps (3) and (4), for several times till a tyre inner coating layer which is 0.5-10 mm in thickness is formed. The anti-puncturing safe tyre not only improves traveling safety, but also has the characteristics of avoidance of tyre replacement and repair, improvement on traveling efficiency and trye airtightness, reduction of dynamic balance deviation, decrease of tyre traveling resistance, consumption reduction, oil economization, ultra-strong temperature adaptability, no anxiety for high-speed traveling, reduction of noise generated by the tyre during traveling, reduction of abrasion, prolongation of the service life and the like.

Description

technical field [0001] The invention relates to a tire, in particular to a puncture-proof 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, and drunk...
