Embodiment 1

[0021] 1. Source of raw materials:

[0022] PA6 was purchased from Taiwan Jisheng, the model is TP-4208, and the relative viscosity is 2.4.

[0023] EBS was purchased from Jinyi Chemical Technology, model EBA-60.

[0024] 2. Raw material formula:

[0025] PA6 59.1%, Melamine Cyanurate 15%, EBS 0.3%, Antioxidant 1098 0.3%, Antioxidant 168 0.3%, and Talc 25%.

[0026] 3. Preparation method:

[0027] Add melamine cyanurate, EBS and antioxidant into a high-speed mixer and mix evenly, then take out the mixture. Add PA6 from the main feeding port of the twin-screw extruder, add the mixture at the first side feeding port, and then add talc powder at the second side feeding port, so that all materials are mixed evenly in the twin-screw extruder , extruded, cooled, and pelletized to obtain a high glow wire temperature flame-retardant polyamide composite material; the extrusion temperature from the feed section to the machine head is: 210°C, 230°C, 250°C, 250°C, 240°C, 235°C ℃, 230...

Abstract

The invention discloses a polyamide composite material with high glowing filament temperature. A raw material formula of the polyamide composite material comprises, by weight, polyamide 40%-70%, halogen-free flame retardant 5%-15%, lubricating agent 0.1%-3%, antioxidant 0.1%-1% and reinforced modifying agent 10%-30%. The halogen-free flame retardant is cyanuric acid melamine. The invention further discloses a preparation method and application of the polyamide composite material with the high glowing filament temperature. The polyamide composite material with the high glowing filament temperature is light in color, light in specific gravity and wide in application range, can be dyed with various colors and has comparative tracking index larger than 500V, and the glowing filament combustion index is 960 DEG C. The polyamide composite material with the high glowing filament temperature can be prepared by means of a conventional device and a conventional method, a manufacture device is not required to be modified, and industrial production is easily performed.

Description

technical field [0001] The invention relates to the field of modified polymer new materials, in particular to a high glow wire temperature flame-retardant polyamide composite material and its preparation method and application. Background technique [0002] Polyamide, commonly known as nylon (PA), is a general term for a class of thermoplastic resins containing repeated amide groups (-NHCO-) ​​in the main molecular chain. Unmodified polyamides have poor flame retardancy and can easily cause fires during use. Therefore, flame retardant modification of polyamide is required in the fields of electronic appliances and other applications. The types of flame retardants that can be used for flame-retardant modification of polyamide mainly include halogen-based, phosphorus-based, nitrogen-based, etc. At present, halogen-based flame-retardant polyamides are the most widely used. The proportion of halogenated flame retardants is large, and halogenated flame retardants usually need t...
