The present invention relates to a lining material of a nonmetal flexible composite pipe and a preparation method. The lining material consists of the following components in the following proportions: 89.5-99.4 wt % of a polymer matrix, 0.5-10 wt % of inorganic particles and 0.1-0.5 wt % of an antioxidant. The preparation method comprises the following steps: (1) preparation of raw materials: raw materials are weighed in a mass ratio for later use; (2) compounding and plasticizing: inorganic particles, a polymer matrix and an antioxidant are added into a twin-screw extruder or a mixer at an extruding or mixing temperature of 190-360° C., and extruded and cooled for later use; and (3) pelleting: the materials after the compounding and plasticizing obtained in the step (2) are pelleted in a pelletizer to obtain the lining material of a nonmetal flexible composite pipe.
