Problems solved by technology

[0005] In current research, glass fiber reinforcement is often used in PBT / PA6 alloys. Although the enhanced mechanical properties lead to poor flame retardancy, a large amount of flame retardant is required to achieve the corresponding flame retardancy, resulting in poor overall performance of the alloy material.

Abstract

Belonging to the technical field of high polymer materials, the invention provides a novel nylon 6-polybutylene terephthalate flame retardant alloy material and a preparation method thereof. According to the invention, an appropriate formula process is adopted, and a unique compound flame retardant is employed for cooperation to prepare the environment-friendly high-performance flame retardant PA6-PBT alloy material, compared with general PBT / PA6 flame retardant materials, the alloy material has obvious advantages in the aspects of rigidity, toughness, heat resistance, flame resistance and dimensional stability, and is easy for molding processing. Also, the added modified kaolin is well compatible with all polymers, the alloy material can stably pass the UL94-V0 flame retardant grade, can stably pass 850DEG C glowing filaments without fire breakout, also can satisfy a lot of occasions with high flame retardant level and performance requirements, and is widely applicable to capacitor shells, load break switches, motor shells, terminal boards, coil skeletons, plugs and circuit connectors, telephone distribution boxes and other low voltage electrical apparatuses.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a kaolin modified nylon 6-polybutylene terephthalate alloy material and a preparation method thereof. Background technique [0002] Nylon 6 (also known as polyamide 6, PA6) is an engineering plastic with excellent mechanical and electrical properties, and also has the advantages of wear resistance, oil resistance, self-lubrication, corrosion resistance and good processing performance. However, PA6 has high water absorption, poor low temperature and dry impact toughness, and poor dimensional stability, which limits its application range to a certain extent. [0003] Polybutylene terephthalate (PBT) is a thermoplastic polyester developed in the 1970s. It has excellent mechanical, electrical, high temperature resistance, moisture resistance, chemical corrosion resistance, good electrical insulation performance, good elasticity, crystallization It has the chara...
