Abstract
The invention aims to provide an improved environment-friendly flame-retardant high-density polyethylene material and a preparation method thereof. The high-density polyethylene (HDPE) is one of important five general plastics, and is widely applied to the fields of valves, pipelines, equipment gaskets, cables and the like due to its good comprehensive performance, rich raw material sources and low cost; but the HDPE belongs to inflammable materials (the oxygen index (01) is only 17.5), so that the HDPE can be used safely only after the flame retardance is improved. The flame retardance is improved by generally adopting a method for adding a flame retardant. According to the preparation method provided by the invention, the flame retardance of the environment-friendly high-density polyethylene material can be obviously improved, and the flame-retardant level of the environment-friendly high-density polyethylene material can reach V0.
