The invention provides a plum blossom pipe and a preparation method thereof, belonging to the technical field of pipe preparation. The preparation method comprises: melting raw materials containing resin, then extruding the above raw materials through a porous plum blossom pipe die, shaping, cooling, cutting, making The plum blossom pipe material is obtained; the above-mentioned raw materials include a composite flame retardant, and the above-mentioned composite flame retardant is composed of a primary polymer including red phosphorus masterbatch, polyvinyl alcohol and toluene diisocyanate in the presence of phthalamide and diclofenac sodium. obtained by cross-linking reaction; the molecular weight of the above-mentioned polyvinyl alcohol is 500-2000. The preparation method provided by the invention can avoid the problem of agglomeration of flame retardant materials, improve the rigidity of the pipe material and the resistance to mechanical damage, and prolong the service life; Excellent corrosion resistance. |
