Embodiment 1

[0026] Step 1, mix 80kg SEBS and 120kg white oil for industrial use according to the ratio, stir and foam in a container for 24 hours to form a mixed material for later use;

[0027] Step 2. Put the foamed mixed material into the reaction pot, add 2.4kg of carbon 5 and 0.8kg of TPE, heat at a temperature of 250-280°C for 20 minutes, stop heating after the mixed material melts, and cool to 190°C. Ready to spray.

[0028] When spraying, the tire should be rotated in a balanced manner at about 90 revolutions per minute, and the thickness of the sprayed leak-proof layer should be 5-8mm. The spraying thickness is controlled by the spraying time and spraying amount. After spraying, the speed of rotation should be increased to 120 rpm, so that under the action of centrifugal force, the anti-leakage layer material will be evenly cooled on the inner wall of the tire, and the cooling time is about 5 minutes, so that the anti-leakage layer of the tire is formed.

Abstract

The invention discloses a tubeless tyre leak-proof material and making and spraying method, which comprises the following parts: 1% SEBS, 1. 5-2% industrial white oil, 0.01-0.03% carbon 9 and 0.01-0.05% TPE. The making method comprises the following steps: blending SEBS and industrial white oil; stirring; foaming to form composite material; putting foamed composite material in the autoclave; adding carbon 5 or carbon 9 and TPE; heating to 250-280 deg. c; cooling to 170-190 deg. c. The spraying method comprises the following steps: spraying fused leak-proof material into tyre at 190-170 deg. c; distributing the lead-proof material on the inner wall of tyre evenly.

Description

technical field [0001] The invention relates to an anti-puncture and anti-leakage material for a tubeless tire and a preparation and spraying method thereof. It belongs to the technical field of organic polymer materials. Background technique [0002] Anti-puncture and anti-leakage tires are a functional product developed in recent years. Currently on the market, you can also see some materials used for anti-puncture tires, which can be roughly divided into: ① tire structure modification type (such as adding thin steel plates to tires); ② liquid type (such as injecting high-viscosity liquid into tires to seal dense material). From the perspective of feasibility and reliability, ① structural change type, the steel plate must be put in when the tire is manufactured, not to mention its reliability, it may not be feasible for many tire manufacturers; ② liquid type, it will affect the safety of driving, It will mainly increase the vibration during driving and the corrosion of ...
