Heat-conducting material with high heat conductivity and leakage prevention function and preparation method and application thereof

The invention belongs to the technical field of liquid metal application, and particularly relates to a heat-conducting material with high heat conductivity and a leakage prevention function and a preparation method and application thereof. The heat-conducting material includes a base body and dopping powder; the base body is liquid metal; and the dopping powder at least comprises silicon carbide.The heat-conducting material has excellent heat conductivity at a certain temperature and pressure, and is pasty when molten, so that the problem of leakage of an existing heat-conducting sheet afterheating is avoided. 本发明属于液态金属应用技术领域，具体涉及一种高导热性防泄漏的导热材料及其制备方法和应用。所述导热材料包括：基体和掺杂粉体；所述基体为液态金属；所述掺杂粉体至少包括碳化硅。在一定温度和压力下，所述导热材料具有优异的导热性能，同时在熔化时呈膏状，因而避免现有导热片受热后泄漏的问题。
