Abstract

The invention relates to the technical field of high polymer materials, and particularly discloses a halogen-free flame-retardant PA antistatic material and a product thereof. The halogen-free flame-retardant PA antistatic material comprises, with relative to 100 parts by mass of a material finished product, 44.5-82.8 parts by mass of PA, 2-25 parts by mass of a conductive medium, 2-5 parts by mass of a toughening agent, 0.2-0.5 part by mass of an anti-dripping agent and a flame retardant, and the flame retardant is a compound of 12-20 parts by mass of a hypophosphite flame retardant and 1-5 parts by mass of an ester flame retardant. The halogen-free flame-retardant PA antistatic material can meet the requirements on antistatic property and high flame retardancy, and has favorable mechanical properties.

Description

【Technical field】 [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant PA antistatic material. 【Background technique】 [0002] Polyamide (PA) refers to a polymer whose main chain contains polar amide groups (-CO-NH-). Originally used as a raw material for making fibers, PA has become a widely used engineering plastic in the industry due to its advantages of toughness, wear resistance, self-lubrication, and wide temperature range. [0003] In order to meet the antistatic properties of electronic and electrical products, PA antistatic materials are usually used to prepare electronic and electrical product accessories. However, in the existing PA antistatic materials, due to the addition of carbon black or carbon nanotubes in the PA material as a conductive medium, the overall mechanical properties of the material are reduced; in addition, the candle wick effect of carbon black and carbon nanotubes will make ...
