Example Embodiment
[0028] Example one:
[0029] A PP-R self-cleaning kitchen and bathroom pipe, the raw material of the inner layer of the pipe includes the following components by weight:
[0030] 100 parts of random copolymer polypropylene particles;
[0031] 2 copies of masterbatch;
[0032] 5 parts of polyhexamethylene biguanide.
[0033] The particle size of the random copolymer polypropylene is 1-4 mm.
[0034] The pipe is divided into three layers, wherein the outer layer is made of random copolymer polypropylene, and the middle layer is a glass fiber reinforced layer.
[0035] The preparation method of the PP-R self-cleaning kitchen and bathroom pipe includes the following steps:
[0036] (1) Mix the random copolymer polypropylene particles, color masterbatch and antibacterial material thoroughly, stir evenly, and input it to the dryer through an automatic suction pump, and dry it at 90°C until the water content is less than 5%;
[0037] (2) The dried mixture is fed into the feed port of the extruder thr
