A marine pressurized high temperature resistant synthetic material and its preparation process. The formula and dosage of synthetic materials are weighed by 95~105 parts of caprolactam, 5~15 parts of polytetrafluoroethylene nanometer powder, 5~15 glass fiber of glass, 0.08 to 0.4 NaOH, 0.005 to 0.05 parts of toluene diisocyanate, including the following operation steps: preparing material to the beginning. The melted caprolactam was mixed with polytetrafluoroethylene nano powder and glass fiber in the melted caprolactam single body. The mixed melt was injected into the reaction kettle and sodium hydroxide was added to the melt. The melt was kept at the temperature of 120 C, and the melts were dehydrated by vacuum and mixed melt polymerization. After the injection of toluene diisocyanate, the melt was injected into dehydration. In the mixed melt, the centrifugal casting mold is then injected immediately, so that the mixed melt is polymerized to demoulding. The synthetic material of the invention has the advantages of large pressure bearing, high temperature resistance and low manufacturing cost, adopting a reasonable preparation process, stable performance and long service life of various aspects of the material.
