Problems solved by technology

The connecting wire of the traditional charger plug is long. In daily use, the connecting wire is exposed outside and needs to be wound frequently. Since the connecting wire sheath needs to protect the normal operation of the internal wire, this has a great impact on the aging resistance and High tear resistance requirements need to be improved urgently

Abstract

The invention discloses a preparation method of a charger plug connecting wire sheath. The preparation method comprises the following steps: uniformly mixing polyurethane rubber, isoprene rubber, C9 petroleum resin and coumarone resin to obtain preformed material; adding stearic acid, a silane coupling agent, vermiculite powder, attapulgite, coal gangue, ground calcium carbonate and zeolite powderinto the preformed material; heating and stirring; heating, and performing vacuum stirring to obtain a rubber compound; adding tert-butyl hydroperoxide, magnesium oxide, an anti-aging agent DFC-34 and an antioxidant TPP into the rubber compound; vulcanizing and moulding to obtain the charger plug connecting wire sheath. According to the preparation method disclosed by the invention, the obtainedsheath has the advantages of remarkably high tensile strength and elongation at break, strong resistance to aging and tearing and high toughness, and avoids the phenomenon of electric leakage on a low-voltage side caused by a high-voltage side, thus the safety of a charger is enhanced, and a user feels safer to use the charger.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to a preparation method for a sheath of a charger plug connecting wire. Background technique [0002] The charger power plug is the energy interface of electronic products such as mobile phones and tablet computers. It plays an important role as an accessory of the charging system. The connecting wire of the traditional charger plug is long. In daily use, the connecting wire is exposed outside and needs to be wound frequently. Since the connecting wire sheath needs to protect the normal operation of the internal wire, this has a great impact on the aging resistance and The requirement for tear resistance is high and needs to be improved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a sheath for a charger plug connection line. The obtained sheath not only ha...
