Abstract

A modified high-density-polyethylane composite comprises the following raw materials: by weight, 75-90 parts of a high density polyethylene, 5-10 parts of magnesium borate whisker, 5-10 parts of talcum powder, 0.2-1 part of calcium stearate, 0.5-1 part of antioxidant 1076, 1-5 parts of maleic anhydride grafted ethylene-propylene-diene rubber, 2-5 parts of a coupling agent, 0.1-0.5 part of ultraviolet absorbent UV-531 and 0.5-1 part of light stabilizer 744. In the modified high-density-polyethylane composite, the high density polyethylene is HDPE310M, the coupling agent is isopropyl tri-(dioctylpyrophosphato) titanate, the magnesium borate whisker is adopted in the composite, and the coupling agent isopropyl tri-(dioctylpyrophosphato) titanate is compounded into the composite, so that the strength and toughness of the composite can be effectively improved, and the composite has good fluidity and is easy to process. Through addition of the ultraviolet absorbent UV-531 and the light stabilizer 744, the outdoor weather resistance of the composite is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a modified high-density polyethylene composite material. Background technique [0002] High-density polyethylene composite materials are widely used in the production of wire and cable, pipes and outdoor materials due to their good electrical insulation properties, heat and cold resistance and good mechanical properties. However, the pure high-density polyethylene material has a short service life outdoors. The existing technology improves its performance by adding a series of additives to increase its service life. However, the strength and toughness of the existing high-density polyethylene composite materials need to be further improved in order to better meet the requirements of the outdoor environment. [0003] At present, improving the mechanical properties of high-density polyethylene composite materials is mainly achieved by adding some reinforcing ...
