| abstract |
The invention discloses an antibacterial, anti-freezing and flame-retardant double-layer toughened composite pipe, which comprises an inner layer and an outer layer, wherein the antibacterial, anti-freezing and flame-retardant double-layer toughened composite pipe sequentially comprises the inner layer and the outer layer from inside to outside, the inner layer is formed by compounding an antibacterial agent, a compatilizer and PE-RT, and the outer layer is formed by compounding a flame retardant, a beta nucleating agent and PPR; the invention not only has all advantages of common plastics in normal temperature environment, but also overcomes the defect of frost resistance in severe cold environment, increases the functions of antibiosis and flame retardance, greatly improves the toughness and the pressure resistance and has greater social benefit. |
