Abstract

The application relates to the field of sockets, and specifically discloses an aging-resistant socket and a preparation method thereof. The aging-resistant socket includes a shell and a wire, and the shell includes the following raw materials: polycarbonate, polyester fiber, plasticizer, 3,4-dihydroxybenzophenone and o-hydroxybenzonitrile; its preparation method is: S1 . Preparation of shell; S2. Preparation of socket. The aging-resistant socket of the present application adopts the method of adding 3,4-dihydroxybenzophenone and o-hydroxybenzonitrile to the raw materials of the shell, and the hydrogen on the phenolic hydroxyl group in the molecular structure of 3,4-dihydroxybenzophenone It will first react with the active free radicals in polycarbonate to generate a stable compound, which inhibits the generation of carbon chain free radicals, and o-hydroxybenzonitrile will supply hydrogen to 3,4-dihydroxybenzophenone, making 3, 4‑Dihydroxybenzophenone continues to react with active free radicals, further inhibiting the generation of carbon chain free radicals, thereby delaying the aging of polycarbonate, and synergistically improving the aging resistance of the prepared shell, which is beneficial to prolong The service life of the socket.

Description

technical field [0001] This application relates to the field of sockets, more specifically, it relates to an aging-resistant socket and a preparation method thereof. Background technique [0002] The socket is almost ubiquitous in daily work and life. It is a manual control tool mainly used for connecting and disconnecting circuits, and the frequency of use is very high. [0003] For example, the Chinese utility model patent whose patent announcement number is CN209200218U discloses a socket, including a shell, the shell is provided with at least one set of inserting compartments for plug insertion, and one set of inserting compartments includes at least two mutually isolated jacks, The two opposite sides of a pair of conductive sheets in the same jack are respectively provided with magnet blocks for attracting each other so that the two conductive sheets are in close contact. [0004] With the above-mentioned socket, the shell of the socket is generally made of plastic. Wh...
