Abstract

The invention relates to a high glowing filament flame-retardant reinforced nylon 6 material and a preparation method thereof. Nylon 6 serving as a base material, glass fibers serving as a reinforcingmaterial, decabromodiphenyl ethane used as a main flame retardant and antimony trioxide serving as a main synergist are compounded with triphenyl phosphate, diethyl aluminum hypophosphite, piperazinepyrophosphate, melamine polyphosphate, zinc borate and other auxiliary flame retardants and synergists, and then are heated, extruded and granulated through double screws to prepare the reinforced nylon product which can pass through a glowing filament at 850 DEG C and can achieve V-0-grade flame retardance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high glow wire flame-retardant reinforced nylon 6 material and a preparation method thereof. Background technique [0002] Polyamide-6, that is, nylon 6, also known as PA6, polyamide 6, nylon 6 has a low melting point, and its process temperature range is very wide. In order to improve the mechanical properties of nylon 6, various modifications are often added agent. At present, there are two types of flame retardant reinforced PA6 on the market, one is a bromine-antimony compound flame retardant, and the other is an organophosphorus flame retardant. The first type of glow wire cannot pass at 855°C, and the second type can pass but is expensive. Contents of the invention [0003] In order to solve the above problems, the present invention provides a kind of bromine-antimony as a flame retardant, compounding some flame retardants and synergists with special effects...
