Abstract

The invention discloses a preparation method of a novel nylon material. The novel nylon material comprises the following components in parts by weight: 72-74, 82-84 or 92-94 parts of raw materials, 3-15 parts of a conductive agent, 1.0-2.5 parts of a lubricating agent, 1-3 parts of an antioxygen, 1.0-2.0 parts of a compatilizer and 0.1-0.8 part of a surface treating agent. The preparation method comprises the following steps: putting the surface treating agent and conducive agent in proportion in a stirring machine, warming and stirring; under a cooling condition, adding the lubricating agent, antioxygen and compatilizer after stirring for low-speed stirring; adding nylon for low-speed stirring; pelleting through extrusion in a double-screw extruder; cooling; sized dicing; drying to obtain the product. The nylon prepared by using the method is high in surface resistivity, and prevents potential safety hazards caused by accumulated static electricity in the using process.

Description

technical field [0001] The invention relates to a method for preparing nylon. Background technique [0002] Polyamide fiber is commonly known as nylon (Nylon), and its English name is Polyamide (abbreviated as PA). It is a general term for thermoplastic resins containing repeated amide groups—[NHCO]—on the main molecular chain. Existing nylons include polydecanediamine sebacate (nylon 1010), polyundecamide (nylon 11), polydodecamide (nylon 12), polycaprolactam (nylon 6), polyhexamethylene sebacamide (nylon 610), polyhexamethylene dodecyl diamide (nylon 612), polyhexamethylene adipamide (nylon 66), polyoctylamide (nylon 8), poly 9-aminononanoic acid (nylon 9), polypara P-phenylene phthalamide (PPTA), poly-m-phenylene isophthalamide (MPIA), polypara-benzamide (PBA), PA6T, PA10T, PA12T, etc. The surface resistivity of the above-mentioned nylon is high, and static electricity is accumulated during use, which brings potential safety hazards. Polyamide fiber is commonly known a...
