The invention relates to the technical field of silicon core tubes, in particular to a corrosion-resistant and flame-retardant silicon core tube. The corrosion-resistant and flame-retardant silicon core tube comprises an outer layer and an inner layer. The outer layer contains nano-SiO₂ and potassium diformate slow-release microcapsules in addition to a traditional resin matrix. The inner layer contains polyurea-coated graphene and ammonium polyphosphate in addition to traditional silicon core masterbatch and a resin matrix. The corrosion-resistant and flame-retardant silicon core tube does not contain zinc naphthenate, polyacrylic acid or chlorinated paraffin. The silicon core tube of the invention has an excellent inhibitory effect on common microorganisms in soil, preventing the tube from being eroded and degraded by microorganisms, and the inhibitory effect can be exerted continuously. It has excellent smoothness with an inner wall friction coefficient as low as below 0.1, good flame retardancy, and does not release toxic gases when burned, making it environmentally friendly.
