Abstract

The invention discloses a nylon 6 / polypropylene composite material as well as a preparation method and application thereof, and belongs to the technical field of high polymer materials. The nylon 6 / polypropylene composite material comprises the following components in parts by weight: 25-62 parts of nylon 6; 5 to 30 parts of polypropylene; 10-40 parts of an inorganic filler; 3-10 parts of a compatilizer; 1 to 5 parts of an ethylene-acrylate-maleic anhydride terpolymer; and 0.1-3 parts of a processing aid. The paint adhesive force of the nylon 6 / polypropylene composite material disclosed by the invention can be below grade 2, and the nylon 6 / polypropylene composite material has no obvious cracking after being soaked in an ethylene glycol solution for 48 hours and has excellent alcoholysis resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more particularly, to a nylon 6 / polypropylene composite material and a preparation method thereof, as well as a preparation method and application thereof. Background technique [0002] The repeating units on the nylon 6 (PA6) molecular chain contain polar amide groups, which can form intermolecular hydrogen bonds, regular structure, crystallinity, and large intermolecular interaction, so nylon 6 has excellent mechanical properties and strength. High rigidity, good toughness, good self-lubrication, good friction resistance, wide operating temperature range, good electrical insulation performance, high volume resistivity, high breakdown voltage resistance, good oil resistance and chemical stability. [0003] Adding glass fiber to nylon 6 can improve the mechanical properties of nylon 6. However, because the amide group in the nylon 6 molecular chain is very easy to form hydrogen bond...
