A kind of preparation method of conductive nylon material

Abstract

The invention provides a preparation method of a conductive nylon material. The method includes the following steps: (1) preparing an ionic liquid from n-butyl bromide and N-vinylimidazole; (2) calcining carbon nanotubes, and processing the calcined carbon nanotubes with a mixed acid to obtain acid processed carbon nanotubes; (3) preprocessing the acid processed carbon nanotubes with titanium chloride to obtain preprocessed carbon nanotubes; (4) carrying out a grafting reaction on the preprocessed carbon nanotubes and the ionic liquid to prepare a conductive agent; (5) weighing nylon and other raw materials according to corresponding weight parts; and (6) mixing the raw materials, and carrying out extruding granulation to obtain the conductive nylon material. The conductive nylon material prepared in the invention has good conductivity.

Description

technical field

[0001] The invention relates to a polymer material, in particular to a preparation method of a conductive nylon material. Background technique

[0002] Polyamide (Polyamide), commonly known as nylon, is a general term for thermoplastic resins containing repeating amide groups -[-NHCO-]- in the main molecular chain. Nylon has the characteristics of many varieties, large output and wide application, and is one of the five major engineering plastics. Due to the wide variety of polyamides, some products are similar in application fields, and some have considerable differences, which need to be carefully distinguished. The main varieties of nylon are PA6 and PA66, which are absolutely dominant; followed by PA11, PA12, PA610, PA612, and PA1010, PA46, PA7, PA9, and PA13. New varieties include nylon 6I, nylon 9T, special nylon MXD6 (barrier resin), etc.; modified varieties include: reinforced nylon, monomer cast nylon (MC nylon), reaction injection molding (RIM) ny...
