Abstract

The invention discloses a halogen-free flame-retardant glass fiber-reinforced PA6 composite material with a high-ignition-temperature glow wire and a high CTI value and a preparation method of the PA6composite material. The PA6 composite material is composed of the following raw materials of: in parts by mass, 40-55 parts of PA6 resin, 0-5 parts of a toughening agent, 10-18 parts of melamine cyanurate flame retardant, 9-13 parts of aluminum hypophosphite flame retardant, 1-4 parts of melamine polyphosphate flame retardant, 20-35 parts of glass fiber, 0.3-0.5 part of an antioxidant and 0.3-1 part of a lubricant. Meanwhile, the invention discloses the preparation method of the halogen-free flame-retardant glass fiber-reinforced PA6 composite material with the high-ignition-temperature glowwire and the high CTI value. The halogen-free flame-retardant glass fiber-reinforced PA6 composite material with the high-ignition-temperature glow wire and the high CTI value has excellent flame retardant performance, high ignition temperature of the glow wire and high anti-tracking performance, and meanwhile the prepared composite material has excellent comprehensive mechanical properties and asimple preparation process, and is worthy of popularization and application.

Description

technical field [0001] The invention relates to a high glow wire high CTI value halogen-free flame retardant glass fiber reinforced PA6 composite material and a preparation method thereof. Background technique [0002] The main feature of nylon is its excellent mechanical properties, such as high tensile strength, good toughness, ability to withstand repeated shocks and vibrations, good wear resistance, excellent self-lubricating properties, etc. It is widely used in machinery, transportation, instrumentation, electronics, electrical, communications and other products. In particular, glass fiber reinforced nylon improves the mechanical properties of nylon and further broadens the scope of use of nylon. However, nylon is a flammable material, and the requirements for flame-retardant materials in various industries have been continuously improved in recent years. Therefore, flame-retardant reinforced nylon has become a hot spot for polymer modified materials. [0003] CN1047...
