Abstract

The invention discloses a preparation method of an environmental-friendly degradable high-density polyethylene pipe material. The polyethylene pipe material is prepared from the following ingredientsin parts by weight: 20 to 40 parts of high-density polyethylene, 10 to 20 parts of toughening master batch, 5 to 10 parts of calcium carbonate superfine powder, 4 to 12 parts of glass fiber, 2 to 6 parts of nanometer silicon micro powder, 2 to 6 parts of graphene, 3 to 9 parts of hollow microspheres, 2 to 8 parts of carbon nanometer tubes, 4 to 10 parts of silane coupling agents and 2 to 8 parts of fire retardants. The preparation method is simple; the prepared polyethylene pipe material has excellent fireproof, pressure-resistant and anti-tearing performance; meanwhile, the degradable performance is good; the environment pollution cannot be caused.

Description

technical field [0001] The invention relates to the technical field of polyethylene pipe material preparation, in particular to a preparation method of an environmentally friendly and degradable high-density polyethylene pipe material. Background technique [0002] High-density polyethylene is usually a linear polymer material with high rigidity and good heat resistance, and is widely used in the manufacture of films, pipes, various hollow products and injection molding products. [0003] With the continuous expansion of the application field of polyethylene pipes and fierce market competition, how to produce pipes that meet the requirements at a lower cost has become the main goal pursued by various manufacturers. The composite materials used for polyethylene filling modification have become the first choice of various manufacturers due to their strong flame resistance, excellent impact resistance, small shrinkage rate of finished products, and low raw material cost. The c...
