Tire material, non-pneumatic tire with hollow cavity and preparation method of non-pneumatic tire

Abstract

The invention discloses a tire material, a non-pneumatic tire with a hollow cavity and a preparation method of the non-pneumatic tire. The tire material takes polyurethane as a main material and a solidifying agent, graphene and white carbon black fibers as auxiliary materials. The non-pneumatic tire comprises a carcass with the hollow cavity and a hub circled with the carcass; the carcass and the hub are fused to form a whole body through glue injection; and the hollow cavity forms a closed type annular construction along with the carcass. The method comprises the following step: carrying out integrated glue injection formation on the hollow cavity and the hub. The non-pneumatic modified polyurethane environment-friendly explosionproof wheel tire is connected with the hub without separation forever, so that the hidden danger that the hub is separated from the tire and the like when the non-pneumatic tire is used on an expressway is not worried again; and by forming an air suction hole / air outlet in the hub to be communicated with the hollow cavity (non inner tube) in the tire, air can naturally flow, and thus heat dissipation and the comfort degree closer to that of a pneumatic rubber tire are reached.

Description

Technical field [0001] The invention belongs to the field of tires, and in particular relates to a tire material, a non-pneumatic tire with a hollow cavity and a preparation method thereof. Background technique [0002] Non-inflatable tires have a long service life due to their non-inflated inner tank. In real life, such as the popular shared bicycles, they are more and more widely used. Existing non-pneumatic tires have contradictions between their comfort and support. Good comfort will cause poor support, and good support will cause poor comfort. A good balance cannot be obtained between the two. [0003] Moreover, most of the existing non-pneumatic tires, most of which are solid tires, are only used at low speeds and cannot be widely used at high speeds. In addition, the non-pneumatic tires on the market are made of separate tires and wheels. There are hidden dangers in the use of tires, which are prone to tire breakage and separation from the wheel hub. Moreover, the existing...

Problems solved by technology

The existing non-pneumatic tires have a contradiction between comfort and support. Good comfort will result in poor support, and good support will result in poor comfort. A good balance cannot be obtained between the two

[0003] Moreover, most of the existing air-free tires, most of which are solid tires, are only used at low speeds and cannot be widely used at high speeds; in addition, the market The non-inflatable tires on the car are completed separately from the tire and the wheel hub. There are hidden dangers in the driving and use of the tire, which is prone to tire rupture and separation from the wheel hub.

Moreover, the wear resistance of existing tire materials is not good enough, and the present invention expects to improve this situation
