Abstract

The invention relates to a high-density polyethylene material and application thereof. The material comprises the components in percent by weight: 100% of high-density polyethylene, 5-80% of para-phthalic metal salt, 1-8% of silicone oil and 0.5-5% of antioxidant. The para-phthalic metal salt is selected from calcium terephthalate, magnesium terephthalate, zinc terephthalate, potassium terephthalate, sodium terephthalate, barium terephthalate, lead terephthalate, aluminum terephthalate, ferrum terephthalate or a mixture thereof. The silicone oil is selected from active silicone oil, dimethyl silicone oil, 201 methyl silicone oil or a mixture thereof. The antioxidant is selected from tris(2,4-ditert-butylphenyl) phosphate, pentaerythrite tetra [beta-(3,5-di-tert-butyl-4-hydroxyphenyl)-propionate], 2,6-di-tert-butyl-4-methylphenol, 2,2'-methylenebis[6-(1,1-dimethylethyl)-4-methyl-phenol or a mixture thereof. The polyethylene material provided by the invention has a small friction coefficient and favorable self-lubricity and can be used for manufacturing optical cable protection sleeves.

Description

technical field [0001] The invention relates to a high-density polyethylene material and its application. Background technique [0002] Polymers usually have high viscosity after melting. During processing, when the molten polymer passes through narrow slits, gates and other flow channels, the polymer melt must produce friction with the surface of the processing machine. These frictions reduce the fluidity of the melt. At the same time, severe friction will make the surface of the equipment rough, lack luster or flow lines, and increase energy consumption; while excessive friction inside the polymer will reduce the stability of the polymer. Cracks are prone to appear on the surface of the product during processing. Lubricant is a kind of processing aid that can reduce the friction between materials and the surface of materials and processing equipment, and reduce the generation of frictional heat. [0003] Optical cables are usually buried underground. In order to effectiv...
