Embodiment Construction
[0009] A kind of FRPP corrugated pipe with good low temperature toughness, made of the following components according to the mass ratio: PP raw material 20 Kg PE raw material 20Kg Low density polyethylene 15Kg Activated calcium powder 42Kg Black masterbatch 2Kg Defoamer 1Kg;
[0010] Then use a mixer to stir evenly, and adopt the prior art to process and extrude.
[0011] The chemical symbol of low-density polyethylene is LDPE; black masterbatch is a new type of special colorant for polymer materials, and the main function of the defoamer is to eliminate moisture in raw materials. Due to the molecular polymerization reaction of PE raw material and PP raw material, this FRPP corrugated pipe has changed the problem of low-temperature brittleness of raw materials and can meet product design requirements.
