The invention discloses a high-modulus
impact-resistant HDPE double-wall corrugated
pipe and a preparation method thereof. The high-modulus
impact-resistant HDPE double-wall corrugated
pipe comprisesthe following raw materials: high-density
polyethylene, high-modulus PP, HDPE stiffening master batch, HDPE
toughening master batch,
polyester modified
acrylic resin,
siloxane modified
acrylic resin,modified color master batch, nano
calcium carbonate, modified talcum
powder,
glass fiber, a
titanate coupling agent, an
antibacterial agent, a
plasticizer and an
antioxidant. High-density polyethyleneand high-modulus PP are used as matrixes, HDPE stiffening master batch and HDPE
toughening master batch are added to serve as preparation base materials of the high-modulus
impact-resistant HDPE double-wall corrugated
pipe, the HDPE stiffening master batch and the HDPE
toughening master batch serve as rigid particles, the high-density
polyethylene is modified through modified talcum
powder, strong chemical bonds are formed, in combination with the
layered structure characteristics of the talcum
powder, the impact strength of the high-density
polyethylene matrix is increased while the rigidityis increased, and the effects of increasing the rigidity and maintaining the
toughness are achieved.
