Problems solved by technology

[0004] Usually the volume resistivity of polyamide is >10 15 Ω, but at present, due to market demand, many require that the material itself has a good antistatic effect, or a conductive effect, so that the material can be used in some materials that need to produce antistatic effects, such as printer components, and domestic antistatic materials The research is still limited to some low-end polypropylene, polystyrene, such materials, and many researched antistatic materials are added with some migratory antistatic agents, which will cause the materials to not be able to maintain antistatic properties for a long time. Effect, after a period of use, as the molecules migrate, the material becomes insulating again

Abstract

The invention discloses an antistatic nylon material and a preparation method thereof. The antistatic nylon material comprises the following components in percentage by weight: 72-94 percent of polyamide, 5-26 percent of antistatic agent, 0.2-0.6 percent of antioxidant, 0.2-0.8 percent of lubricant and 0.3-0.6 percent of nucleating agent. The surface resistivity of a polyamide material is greatly reduced, and the volume resistivity of the antistatic nylon material is controlled to be 107-1010ohm and maintains in the stable state for a long time. The invention provides an economic, applicable and permanent antistatic nylon material with obvious and stable antistatic effect.

Description

[technical field] [0001] The invention relates to the field of polymer materials, in particular to an antistatic nylon material and a preparation method thereof. [Background technique] [0002] Polyamide (PA, commonly known as nylon) is the first resin developed by DuPont in the United States for fiber, and it was industrialized in 1939. In the 1950s, the development and production of injection molding products began to replace metals to meet the requirements of lightweight and cost-reducing downstream industrial products. PA has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, low friction coefficient, certain flame retardancy, easy processing, suitable for glass fiber and Other fillers are filled and modified to improve performance and expand application range. There are many varieties of PA, including PA6, PA66, PA11, PA12, PA46, PA610, PA612, PA1010, etc., as well as m...
