Problems solved by technology

[0003] HDPE is one of the five most commonly used plastics in the world. Due to its good toughness and processability, it is widely used, and it is also widely used in municipal water supply and drainage pipes. Conventional HDPE double-wall corrugated pipes generally use talcum powder and calcium carbonate as reinforcement materials. Compared with glass fiber, there are disadvantages such as low strength, large weight, and obvious size shrinkage, which lead to problems such as low ring stiffness, poor external pressure resistance, and high cost.
[0004] However, in the existing technology, the preparation of ultra-fine glass fiber cotton reinforced masterbatch has the disadvantages of low concentration, pollution of toner dyeing, poor dispersion of glass fiber in resin, and low degree of surface activation.

Abstract

The invention discloses an ultra-micro glass fiber enhanced master batch applied to an HDPE (High-density Polyethylene) double-wall corrugated tubular product. The ultra-micro glass fiber enhanced master batch is prepared by internally mixing by utilizing an internal mixer to obtain a uniform melt and extruding and granulating the molded uniform melt through a single-screw extruder. Nano carbon black in the ultra-micro glass fiber enhanced master batch prepared by the invention has the advantages of great strength and light weight; the HDPE double-wall corrugated tubular product prepared from the ultra-micro glass fiber enhanced master batch has the advantages of small dimension shrinkage rate, smooth and clean surface, high elastic modulus and high ring stiffness.

Description
