Title:
POLYAMIDE COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/212819
Kind Code:
A1
Abstract:
Disclosed is a polyamide composite material, comprising the following components in parts by weight: 25-85 parts of a polyamide resin; 10-50 parts of glass fibers; 5-25 parts of polytetrafluoroethylene; and 0.1-2 parts of at least one of a K/Na/Ca/Mg/Ba/Zn/Li/Al salt of montanic acid. The montanate can efficiently inhibit free hydrogen fluoride in the polytetrafluoroethylene, thereby efficiently inhibiting free silicon in the glass fibers, and improving the electric properties of the material.
