Abstract

The invention discloses a preparation method of low-cost mobile phone charger casings. The preparation method comprises the following steps: performing uniform stirring on polychlorotrifluoroethylene,styrene-butadiene thermoplastic elastomer, nitrile rubber, disproportionated rosin, potassium titanate fiber, maifan stone powder, diatomaceous earth and hollow glass microspheres, adding t-butyl hydroperoxide, lanthanum oxide, praseodymium oxide, antioxidant 164 and antioxidant TPP, then performing uniform stirring continuously, performing hot press forming, and then performing blast drying to obtain the low-cost mobile phone charger casings. According to the preparation method of the low-cost mobile phone charger casings, the obtained mobile phone charger casings have good toughness, are not easy to bend when falling off or impacted, have extremely high pressure bearing capacity, and have extremely excellent heat resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to a method for preparing a mobile phone charger shell with low cost. Background technique [0002] A charger generally refers to a device that converts alternating current to low-voltage direct current. Chargers are widely used in various fields, especially in the field of life, they are widely used in mobile phones. The charger is a static converter device that uses power electronic semiconductor devices to convert alternating current with constant voltage and frequency into direct current. The charger has a wide application prospect in the occasions where the battery is used as the working power source or the backup power source. However, the current charger shell has technical problems of poor toughness and high cost, which need to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invent...
