[0034] The preparation method and the process of the halogen-free reinforced flame-retardant high-CTI value PA6 circuit breaker material of the present invention include the following steps:
[0035] (1) Compounding treatment of halogen-free flame retardants (proportion by mass parts): compound halogen-free flame retardants (92-96%), silane coupling agent KH560 (1-4%), grafted Put the polar siloxane E525 (3%-5%) into the high mixer, mix and stir for 3-6 minutes, and the released material is the compound halogen-free flame retardant; the nitrogen-based flame retardant is low-toxic, non-corrosive, and Heat and UV temperature, good flame retardant effect and low price; the disadvantage is its poor dispersion in the substrate. After the present invention coats it, it overcomes the shortcoming of poor dispersibility and has good dispersibility;

Abstract
The invention discloses a halogen-free enhanced flame-retardant high-comparative tracking index (CTI) value polyamide6 (PA6) material for a circuit breaker and a preparation method thereof, and relates to a thermoplastic polymer fiber enhanced flame-retardant material and a preparation method thereof. The material solves the problem that the conventional halogen-free enhanced flame-retardant PA6 has low compatibility, low comparative tracking index (CTI value), poor mechanical property, low heat resistance and unqualified 960-degree glowing filament. The material is prepared from the following components: PA6 resin, glass fibers, a silane coupling agent, a complex halogen-free flame retardant, an antioxidant, a weather-resistant agent and a processing agent. The method for preparing the material comprises the following steps of: performing combinatorial optimization on an extruder screw, uniformly mixing the PA6 resin, the complex halogen-free flame retardant, the antioxidant and the processing agent and putting into a double-screw extruder; quantitatively adding the glass fibers, fully melting, compounding, extruding through a machine head, bracing wires, cooling, granulating and drying in the double-screw extruder; and finally, packaging. The product has the advantages of high CTI value, good flame retardant property, excellent mechanical property, high heat resistance and good performance of the glowing filament, and the preparation method is simple in process.
Description
technical field [0001] The invention relates to the field of polymer material technology and engineering, in particular to a preparation method and process of a thermoplastic polymer fiber-reinforced halogen-free flame-retardant high-CTI value circuit breaker material. Background technique [0002] Nylon is the most diverse and widely used engineering plastic in the world. The main varieties are: nylon 6 (PA6), nylon 66, nylon 610, etc. Nylon 6 is used in many fields, but nylon 6 is flammable, so it is necessary to develop flame-retardant nylon 6 with high electrical insulation performance. [0003] At present, most people use the method of adding halogenated flame retardants in the flame retardant modification of nylon 6. However, the potential hazards of traditional halogenated flame retardants to the human body and the environment are increasingly recognized and understood by people, and the use of halogen-free flame retardants has increasingly become a hot spot and an ...
