specific Embodiment approach 1

[0032] Specific implementation mode one: as figure 1 As shown, a kind of E-TPU tire is characterized in that: the annular tire body 6 is between the outer protection layer 1, the liner 8 and the inner ring protection layer 3, the outer protection layer 1, the liner 8 and the inner ring protection layer 3. Discontinuous wrapping of the tire body 6. The beneficial effect of discontinuous wrapping is that it is easy to manufacture, does not require complicated molds, and the tire is light in weight and low in cost; the tire body 6 is composed of countless E-TPU foamed elastic particles. The method of melting or steam molding is bonded together; the outer protective layer 1 is arranged along the outer circumference of the tire body 6, the lining 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 ar...

specific Embodiment approach 2

[0040] Specific implementation mode two: as figure 2 , 4 Shown, described E-TPU tire, only tire body 6 is hollow 4, and is arranged along the interior of annular tire body 6, and hollow 4 is filled with compressed air or not filled with compressed air. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0041] Specific implementation mode three: as image 3 As shown, in the E-TPU tire, a heat insulating layer 7 is arranged between the outer protective layer 1 and the tire body 6 . Other compositions and connections are the same as those in Embodiments 1 and 2.

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 an E-TPU tire and a manufacturing method, which are used for tricycles, bicycles, sports cars, scooter, toy cars, vehicles for the disabled and other low-speed vehicles or non-motor vehicles or motor vehicles. E-TPU tires and manufacturing methods. Background technique [0002] At present, there are many types of non-pneumatic tires at home and abroad, most of which are solid structures. The solid interior is filled with plastic, rubber, polyurethane elastomer or composite elastomer, etc. The outer material of the tire wrapping the solid interior is rubber to achieve the function of non-inflation. This tire is currently mainly used for engineering machinery tires, mining machinery tires, and automobile tires. [0003] The patent "Pneumatic-Free Plastic Tire" (patent number: ZL200820173551.8) discloses a tire whose outer tire is a mixture of rubber powder generated from waste rubber and granules generated from waste plastic. Li...
