Abstract

The invention provides a long carbon chain nylon wrist strap, and a preparation method thereof. According to the preparation method, in injection moulding process, glass fiber three-dimensional band shaped fabric is subjected to pre-embedding in nylon 1012 plastic strap. The preparation method comprises following steps: first, glass fiber is processed in to glass fiber yarn, and the glass fiber yarn is subjected to knitting so as to obtain the three-dimensional band shaped fabric; the glass fiber three-dimensional band shaped fabric is introduced into an injection moulding mould; and injectionmoulding is carried out. Nylon 1012 is taken as a raw material; the produced nylon 1012 plastic band possesses better aging resistance, oil resistance, acid and alkali resistance, heat resistance, cold resistance, deformation resilience, flame resistance, and light aging resistance. The loose glass fiber is subjected to mutual connection so as to obtain the glass fiber three-dimensional band shaped fabric, the glass fiber three-dimensional band shaped fabric can be taken as a reinforcing supporting skeleton of nylon 1012 plastic band, wrist strap using performance is improved, and service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a long carbon chain nylon wristband and its preparation method and application. Background technique [0002] Wristbands, also known as wristbands, as the name suggests, refer to belts worn on the wrists of people, such as watch chains in watches, plastic straps worn on the wrists in smart bracelets, and medical straps worn on the wrists.
