The present invention provides a novel high temperature-resistant heat-insulation composite bushing, which comprises a liner pipe 1, a high temperature-resistant heat-insulation coating layer 2 dipcoated on the liner pipe and an external bushing 3 woven on the high temperature-resistant heat-insulation coating layer. The liner pipe is a glass fiber braided tube and the external bushing is an aramid fiber braided bushing. As the glass fiber braided tube is used as the skeleton base for the liner pipe, the present invention effectively solves the phenomena in the prior art such as separation between the high temperature-resistant heat-insulation coating layer and a silicon rubber liner pipe, foaming, tube obstruction, and the like; meanwhile, aramid fiber begins to be carbonized at 350 DEG C, thus further increasing the heat insulation effect of the product provided by the present invention. Compared with the prior art, the present invention has the advantages of no delamination, no foaming, no tube obstruction, good heat insulation effect, low production cost as well as no pollution to human and environment, which is particularly adopted in spaceflight, aviation and missile weapon control equipment.
