Description

technical field

[0001] The invention relates to a high glow wire and high CTI reinforced flame retardant PA6 composite material, in particular to a high glow wire high CTI reinforced flame retardant PA6 composite material which can be used in the fields of circuit breakers, temperature control switches and other electronic appliances and a preparation method thereof. Background technique

[0002] PA6 is a translucent or opaque milky white semi-crystalline polymer, and it is one of the varieties with the largest output and widest application in the polyamide family. It has excellent thermodynamic properties, heat resistance, low friction coefficient, wear resistance, good self-lubrication, oil resistance, weak acid resistance, good electrical insulation and many other advantages. It is widely used in electronic appliances, automobiles, machinery and other fields. With the development of human living standards, various fields have more stringent requirements on the flame retar...
