The invention provides a self-sealing adhesive as well as a preparation method and application thereof. The preparation method of the self-sealing adhesive comprises a mixing step and a vulcanization step, wherein in the mixing step, peroxide is added under the condition that the temperature is not higher than 80 DEG C. The self-sealing adhesive has excellent high-temperature anti-outflow performance, can quickly block a nail hole after a nail is pulled out, can continuously and effectively block the nail hole under the action of internal air pressure of a tire, does not flow out of the nail hole, can block the nail hole for a long time, and ensures that the tire does not leak air. The preparation method has the characteristics of simplicity and high efficiency, and can enable the self-sealing adhesive to obtain higher elastic modulus by simply changing the adding temperature of the peroxide under the condition of not changing the composition of the self-sealing adhesive, thereby obtaining better high-temperature anti-outflow performance.

    本发明提供一种自密封胶及其制备方法和应用,所述自密封胶的制备方法包括混炼步骤和硫化步骤;其中,在混炼步骤中,过氧化物在不高于80℃的温度条件下加入。所述自密封胶具有优异的高温抗流出性能,能够在钉子拔出后快速封堵钉孔,且所述自密封胶还能在轮胎内部气压的作用下,继续有效封堵钉孔,同时也不会从钉孔处流出,能够做到长期封堵钉孔,保证轮胎不漏气。所述制备方法具有简易、高效的特点,其能够在不改变自密封胶的组成的情况下,通过简单改变过氧化物的加入温度,使自密封胶获得更高的弹性模量,进而获得更佳的高温抗流出性能。
