High-strength MPP pipe and preparation method thereof

The invention relates to the technical field of MPP pipes, in particular to a high-strength MPP pipe which is prepared from the following raw materials in parts by weight: 30-42 parts of modified polypropylene, 10-15 parts of silicone rubber, 3-5 parts of polytetrafluoroethylene, 3-5 parts of magnesium citrate, 2-4 parts of calcium formate, 3-6 parts of hexagonal boron nitride, 5-9 parts of glassfiber, 4-8 parts of graphite fluoride, 8-10 parts of a flame retardant and 5-7 parts of a heat preservation agent. The high-strength MPP pipe contains magnesium citrate and calcium formate, the magnesium citrate and the calcium formate can effectively improve the frost resistance of the MPP pipe, then the MPP pipe has good strength in an environment with a large temperature change range, the magnesium citrate can further improve the compression resistance and the tensile property of the MPP pipe, the calcium formate can improve the wear resistance of the MPP pipe, and the combination of the two can further improve the
