本发明提供了一种具有静音功能的气凝胶泡沫及其制备方法、轮胎。上述制备方法包括以下步骤:步骤S1,将MXene分散液和氧化石墨烯分散液混合,形成混合分散液;步骤S2,将混合分散液进行冷冻干燥,得到MXene掺杂的氧化石墨烯;步骤S3,使MXene掺杂的氧化石墨烯进行还原反应,得到具有静音功能的气凝胶泡沫。利用本发明制备方法能够制备得到良好柔性的且具有三维连续多孔网络结构MXene掺杂的石墨烯气凝胶泡沫,该材料对空腔噪音具有良好的吸收作用,将其应用于轮胎内,能够显著降低轮胎的噪音,提高乘客的乘车舒适性并减少对环境的噪音污染。

    The invention provides aerogel foam with a mute function, a preparation method of the aerogel foam and a tire. The preparation method comprises the following steps: S1, mixing an MXene dispersion liquid and a graphene oxide dispersion liquid to form a mixed dispersion liquid; S2, carrying out freeze drying on the mixed dispersion liquid, so as to obtain MXene doped graphene oxide; and S3, carrying out a reduction reaction on the MXene-doped graphene oxide to obtain the aerogel foam with the mute function. The MXene-doped graphene aerogel foam with good flexibility and a three-dimensional continuous porous network structure can be prepared by utilizing the preparation method, the material has a good absorption effect on cavity noise, and when the material is applied to a tire, the noise of the tire can be remarkably reduced, the riding comfort of passengers is improved, and the noise pollution to the environment is reduced.
