Embodiment Construction
[0034] The main component scheme of the gel state elastomer material is shown in Table 1:
[0035] Table 1
[0036] Unit:kg
[0037]
[0038]
[0039] Mix the components in the above scheme in a reaction kettle, raise the temperature to 200-300°C while stirring, until dispersed into a uniform flowable blend, that is, a molten gel-like elastomer blend is obtained.
[0040] The preparation method of air-run-proof tire of the present invention:
[0041] The tire device is rotated at a certain speed on the fixture, and the molten gel-like elastomer blend obtained in the above scheme is sprayed to the bottom of the inner wall of the rotating tire by a delivery pump at a flow rate of 50-200g / second. Under the action of the tire, a layer of uniform elastomer coating layer 3 with self-sealing function is formed on the inner wall of the tire, with a thickness of 3-5mm.
[0042] As a preferred solution, when spraying, first spray one l...
