specific Embodiment approach 1

[0032] Specific implementation one: as figure 1 As shown, an E-TPU tire is characterized in that: the annular tire body 6 is located between the outer protective layer 1, the lining 8 and the inner ring protective layer 3, the outer protective layer 1, the lining 8 and the inner ring protective layer 3. 3. The tire body 6 is discontinuously wrapped. The beneficial effect of discontinuous wrapping is that it is simple to manufacture, does not require complex molds, the tire is lightweight, and the cost is low; the tire body 6 is composed of countless E-TPU foamed elastic particles. The method of melt or steam molding is bonded together; the outer protective layer 1 is arranged along the outer circumference of the tire body 6, the liner 8 and the inner ring protective layer 3 are arranged along the inner circumference of the tire body 6, and the tire rotates When the outer protective layer 1 is in contact with the ground, the lining 8, the inner ring protective layer 3 are conne...

specific Embodiment approach 2

[0040] Specific implementation two: as figure 2 , 4 As shown, in the E-TPU tire, only the tire body 6 is hollow 4, and is arranged along the inside of the annular tire body 6, and the hollow 4 is filled with compressed air or not filled with compressed air. Other components and connection relationships are the same as in the first embodiment.

specific Embodiment approach 3

[0041] Specific implementation three: as image 3 As shown, in the E-TPU tire, an insulating layer 7 is provided between the outer protective layer 1 and the tire body 6 . Other compositions and connection relationships are the same as those in the first and second embodiments.

Abstract

The invention discloses an E-TPU (expanded thermoplastic polyurethane) tire and a manufacturing method thereof, and in particular relates to an E-TPU tire which is used in low-velocity cars, such as tricycles, bicycles, sport cars, scooters, toy cars, and disabled cars, or no-motor cars or motor-cars, and a manufacturing method of the tire. The tire is characterized in that a circular-ring-shaped tire body is positioned among an outer protection layer, a lining and an inner ring protection layer; the tire body is wrapped with the outer protection layer, the lining and the inner ring protection layer in a non-continuous manner; the tire body is formed by bonding a plurality of E-TPU foamed elastic grains by an adhesive or by adopting a surface hot melting or vapor mold forming method; the outer protection layer, the lining and the inner ring protection layer are bonded with the tire body by adopting an adhesive or in a heating manner; the outer protection layer, the lining and the inner ring protection layer are made from rubber or rubber compounds or rubber compositions or polyurethane elastomers. The tire disclosed by the invention is free of air inflation, and has the characteristics of being capable of resisting bursting and resisting impaling, free of maintenance, light in weight, good in elasticity, good in friction force with the ground, low in manufacture cost, long in service life and the like.

Description

technical field [0001] The invention relates to E-TPU tires and a manufacturing method, which are used for low-speed vehicles such as tricycles, bicycles, sports vehicles, scooters, toy vehicles, vehicles for the disabled, or non-motor vehicles or motor vehicles. Background technique [0002] At present, there are many types of air-free tires at home and abroad, most of which are solid structures. The solid interior is filled with plastic, rubber, polyurethane elastomer or composite elastomer. This kind of tire is currently mainly used in construction machinery tires, mining machinery tires, and automobile tires. [0003] The patent "Pneumatic Free Plastic Tire" (patent number: ZL200820173551.8), a tire with a tire made of waste rubber generated rubber powder and waste plastic generated particles was announced. Life is not guaranteed. [0004] The patent "a tire with composite elastomer filling the inner cavity and its preparation method" (patent number: ZL200910192205.3),...
