Problems solved by technology

The amount of flame retardant added in non-reinforced flame-retardant nylon is more, and it is more difficult to flame-retardant. This requires the synergist and bromine to be efficient and synergistic. Otherwise, the amount of flame-retardant 1.6mmV0 is difficult to meet

Abstract

The invention relates to a low-cost high glowing filament flame-retardant PA6 material which is prepared from the following raw materials by weight: 70 percent of PA6 resin, 8.5 to 16.5 percent of a bromine-antimony main flame retardant, 12 to 20 percent of a synergistic flame retardant, 0.5 percent of a flowing agent and 1 percent of black master batch. A preparation method comprises the following steps: mixing the components in a high-speed mixer for 1-2 minutes, and carrying out extrusion granulation on the mixture in a double-screw extruder. The flame-retardant PA6 provided by the invention is low in cost, and meets the requirements of 800 DEG C glowing filament unattended electric appliances in the European Union IEC60695. The material has the characteristics of full-automatic injection molding, no rubber mouth whitening, high cost performance and high CTI, can be used for electronics and electric appliances, and is particularly suitable for wiring shells of air conditioner compressors.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a low-cost high-glow wire flame-retardant PA6 material and its preparation method and application. Background technique [0002] Nylon PA resin is widely used in home appliances, electronic appliances, industrial power engineering, high-speed rail and automobile industries. Industrial power engineering, home appliances and electronic appliances mostly use flame-retardant nylon to prepare plastic parts, including various coils of motors and compressor covers of air conditioners. and electrical switches etc. Flame-retardant nylon materials have become high-quality materials in many fields due to their excellent flame-retardant properties, excellent mechanical properties, outstanding electrical insulation properties, good heat resistance stability, product development flexibility and cost controllability. . [0003] Reinforced flame retardant nylon, including glass fib...
