Abstract

The invention relates to an environment-friendly flame-retardant glass fiber reinforced PA6 (Polyamide 6) material and a preparation method thereof. The environment-friendly flame-retardant glass fiber reinforced PA6 material is prepared from the following components in parts by weight: 45-82 parts of PA6, 6-20 parts of compound flame retardant, 3-15 parts of antimony trioxide, 20-30 parts of glass fiber, 2-10 parts of compatilizer, 0.1-1 part of antioxidant and 0.1-1 part of oxide. The method comprises the following steps of: weighing raw materials according to a formula, and putting into a highly mixing machine for mixing for 2-5 minutes; and discharging, and extruding and pelletizing by using a double-screw extruder to obtain the environment-friendly flame-retardant glass fiber reinforced PA6 material. Compared with the prior art, the environment-friendly flame-retardant glass fiber reinforced PA6 material has the advantages of high glowing filament ignition temperature (GWIT), environment friendliness, balanced comprehensive performance, high CTI (Comparative Tracking Index) value, high GWIT value and the like.

Description

technical field [0001] The present invention relates to one kind, especially relates to a kind of high CTI value, high GWIT value environment-friendly flame-retardant glass fiber reinforced PA6 material and its preparation method. Background technique [0002] Nylon (Nylon), Chinese name polyamide, English name Polyamide (referred to as PA), is a general term for thermoplastic resins containing repeated amide groups -[NHCO]- on the main molecular chain. Its name is determined by the specific number of carbon atoms in the synthetic monomer, such as: nylon-6, 66, 1010, 610. It has high crystallinity and obvious melting point; it has high surface hardness, wear resistance, small friction coefficient, and self-lubrication and noise reduction. It has good low temperature performance and certain heat resistance (it can be used below 100 degrees). Non-toxic, odorless, non-mildew, self-extinguishing, good weather resistance, but poor dyeing. In the 21st century, electronic, elect...
