Abstract

The invention discloses an attapulgite / polyphenylether nanocomposite material and a preparation method thereof. The attapulgite / polyphenylether nanocomposite material, which takes modified attapulgite as a core and takes polyphenylether as a shell, is prepared through firstly carrying out hydrophobic modification on attapulgite and then adopting an in-situ polymerization method. The material has excellent mechanical properties, processability, heat resistance, flame retardance and odor, and can be widely applied to electrical and electronic equipment components, vehicle equipment components, chemical equipment components, and even ships, bridges, building materials and food packages.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a preparation method of attapulgite / polyphenylene ether nanocomposite material. Background technique [0002] In recent years, with the development of various equipment towards the lightweight direction of replacing steel with plastic, materials made of polyphenylene ether resin with high heat resistance, flame retardancy and chemical resistance are more and more used in Various electrical and electronic equipment parts, vehicle equipment parts, and chemical equipment parts, even in ships, bridges, and building materials. [0003] Polyphenylene ether resin has good mechanical properties, electrical properties, heat resistance, flame retardancy and chemical stability, etc., but polyphenylene ether products are prone to stress cracking and low notched impact strength, which are usually improved by adding tougheners. The addition of flammable toughening agents will lead...
