The nonmetal composite sealing ring manufactured by the invention has excellent high temperature resistance, high pressure resistance and self-adaptability, and the multiple sleeved resin layers are combined with various rubbers, so that the sealing ring has excellent explosion-proof performance, can work for more than 300 hours under the working conditions of 400 DEG C and 200 MPa, can replace a metal sealing ring, greatly reduces the installation difficulty of a sealing assembly, and is suitable for large-scale popularization and application. The problem that no high-temperature-resistant, high-pressure-resistant and self-adaptive nonmetal sealing ring exists under the high-temperature and high-pressure working conditions is solved, and the sealing ring has wide application prospects in high-temperature and high-pressure equipment in the industries of military industry, petrochemical industry, new energy and the like.
