Modified polyvinyl chloride cable material with favorable antioxidation and anti-aging effects and preparation method thereof

Abstract

The invention discloses a modified polyvinyl chloride cable material with favorable antioxidation and anti-aging effects. The invention is characterized in that the polyvinyl chloride cable material is prepared from the following raw materials in parts by weight: 13-15 parts of carbon nanotube, 12-14 parts of polyethylacrylate, 1.2-1.3 parts of titanate coupling agent TC-F, 5-7 parts of flame retardant DOPO, 0.03-0.04 part of lauroyl peroxide, 67-70 parts of polyvinyl chloride resin SG, 10-12 parts of light calcium carbonate, 1-1.2 parts of dimethyl fumarate, 8-10 parts of DBP (dibutyl phthalate), 2-3 parts of polyethylene wax, 0.5-0.8 part of bis thiodipropionic acid, 0.8-1.2 parts of 2,6-di-tert-butyl-4-methylphenol, 2-3 parts of monoglyceryl stearate and 7-9 parts of assistant. The formula is special, and the carbon-nanotube-base polymer is added into the cable material to enhance the antistatic property and flame retardancy of the polyvinyl chloride. The 2,6-di-tert-butyl-4-methylphenol and the like are added to obviously enhance the antioxidation and anti-aging effects.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a modified polyvinyl chloride cable material with good anti-oxidation and anti-aging effects and a preparation method thereof. Background technique [0002] Ordinary PVC sheath has a simple molding process, but the texture of PVC is relatively hard, and it is not wear-resistant enough. It generally has a large shrinkage rate, poor oxidation resistance, and is easy to age. Therefore, it is usually only used for fixed and non-moving occasions. cable jacket. [0003] Carbon nanotubes are currently the materials with the highest specific strength that can be prepared. If other engineering materials are used as the matrix and carbon nanotubes to make composite materials, the composite materials can show good strength, elasticity, and fatigue resistance, which will greatly improve the performance of the composite materials; the hardness of carbon nanotubes and Diamond is equivalent, bu...
