| titleOfInvention | Preparation method of HDPE composite material for outer layer of double-wall corrugated pipe |
| abstract | The invention discloses an HDPE composite material used for the outer layer of a double-wall corrugated pipe and a preparation method thereof. agent, coupling synergist, antioxidant, color masterbatch; add HDPE into the single-screw hopper, plasticize the HDPE flakes and remove impurities by quantitative feeding, and force-feed it into the parallel co-rotating twin-screw; add the remaining raw materials to the high-speed mixer Mix evenly in the machine; feed the mixed material with a screw feeder, enter the parallel co-rotating twin-screw and mix with the plasticized and impurity-removed HDPE, extrude, then cool and pelletize to obtain a double wall HDPE composite material for the outer layer of corrugated pipes; the composite material prepared by the invention is used for the production of the outer layer of double-wall corrugated pipes, and various indicators such as ring stiffness, impact performance, ring flexibility performance can meet the requirements of the national standard, and have appearance color It has the advantages of uniform, flat and smooth, stable production and pipe performance, and low production cost. |
