The invention relates to the technical field of cable materials, in particular to a rat-proof core-shell structure, a preparation method of the rat-proof core-shell structure, low-temperature-resistant rat-bite-proof polyurea and a preparation method of the low-temperature-resistant rat-bite-proof polyurea. According to the rat-proof core-shell structure, actinomycete ketone is wrapped with capsaicin, so that the toxicity of the actinomycete ketone and the irritation of the capsaicin are reduced the core-shell structure can be uniformly dispersed into the polyurea material; according to the low-temperature-resistant rat-bite-proof polyurea provided by the invention, a double-layer polyurea core-shell structure is adopted to wrap actinomycete ketone and capsaicin, an isocyanate group is reserved on the outermost layer and reacts with a polyurea B component amino curing agent, the core-shell structure is uniformly dispersed in a polymer, and the actinomycete ketone is wrapped in the double-layer core-shell stru
