The invention provides a preparation method of a flexible silica gel conductive material based on modified graphite, which comprises the following steps: dispersing modified graphene in an organic solvent, then adding a surfactant, and dispersing to obtain a first solution; adding the first solution into silica gel, uniformly stirring, then adding a curing agent, and continuing to obtain a second solution; slowly pouring the second solution into a mold, and curing to obtain the product. The silica gel conductive material can effectively solve the problem that an existing conductive material is poor in conductivity. 本发明提供了一种基于改性石墨的柔性硅胶导电材料的制备方法，包括以下步骤：将改性石墨烯分散于有机溶剂中，然后加入表面活性剂，分散后得到第一溶液；将第一溶液加入硅胶中，搅拌均匀，然后向其中加入固化剂，续绊后得到第二溶液；将第二溶液缓慢倾倒至模具中，固化，制得。该硅胶导电材料可有效解决现有的导电材料存在的导电性差的问题。
