Problems solved by technology

For improving the antibacterial and bacteriostatic effects of PE pipes, the existing technology is mainly realized by adding inorganic antibacterial agents such as silver, copper, zinc, titanium, etc. Although simple inorganic antibacterial agents have good thermal stability, they cannot be used in plastic extrusion and processing It will not decompose and deteriorate during the process

Abstract

The invention discloses a preparation method of an anti-aging and anti-bacterial PE pipe. The preparation method comprises the following steps: adding 3-8% of nano-modified bamboo charcoal plastic particles into PE resin, uniformly mixing, heating to 170-210 DEG C, then extruding by a twin-screw extruder, cooling and performing vacuum shaping to obtain the anti-aging and anti-bacterial PE pipe. The core of the invention is that the nano-modified bamboo charcoal plastic particles are adopted to replace carbon black and an inorganic metal antibacterial agent, so that the PE pipe has good anti-aging and anti-bacterial performances. The preparation method disclosed by the invention has the advantages of strong practicality, low cost, greenness and environmental friendliness, the nano-modified bamboo charcoal plastic particles have good dispersibility and stable natures, and the obtained PE pipe has excellent anti-aging and anti-bacterial performances, as well as relatively strong actual application value and market development prospects.
