Abstract

The invention discloses a nylon 66 / polyaminated bismaleimide composite for inner sheaths of heat-resisting power lines and a preparation method of the nylon 66 / polyaminated bismaleimide composite. The nylon 66 / polyaminated bismaleimide composite comprises, by weight, 39-57 parts of nylon 66, 18-26 parts of polyaminated bismaleimide, 15-25 parts of poly(2(phenoxy) accidentally phosphorus nitrene), 24-32 parts of blast furnace water slag micro-powder, 2-4 parts of stannous chloride, 3-5 parts of N-methyl-p-toluenesulfonamide, 5-10 parts of potassium fluozirconate, 10-15 parts of dimethyl maleate, 4-8 parts of zinc hydroxystannate, 3-5 parts of cuproous bromide, 4-6 parts of oxidized polyethylene wax, 5-8 parts of perfluopolyether, 15-25 parts of colloidal graphite powder and 18-27 parts of flame retardant particles. The nylon 66 / polyaminated bismaleimide is good in mechanical property, wear-resisting property and aging resistance.

Description

technical field [0001] The invention relates to a nylon 66 / polyaminobismaleimide composite material for an inner sheath of a heat-resistant power cord and a preparation method thereof, belonging to the technical field of polymer material processing. Background technique [0002] The power cord is a wire that transmits current, which is mainly composed of an outer sheath, an inner sheath, and a conductor. The inner sheath is a layer of polymer material that wraps the cable between the shielding layer and the core. It is generally polyvinyl chloride plastic or polyethylene plastic, and there are also low-smoke and halogen-free materials. Its function is to prevent the insulating layer from contacting water. , air or other objects in contact, to avoid moisture insulation and insulation from mechanical damage. At present, there are many kinds of inner sheath materials for power cords on the market. However, with the rapid development of science and technology, the heat resistan...
