Abstract

The invention is suitable for the field of plastic and provides a nylon composite material, preparation method and an application thereof. The nylon composite material comprises nylon 66, nylon 6, fire retardant, fire retardant synergist, anti-oxygen and fillers. According to the nylon composite material, the nylon 66 and the nylon 6 are served as foundational resin and compounded with the fire retardant, wherein particularly bromination styrene and antimony chemical compound are served as the fire retardant so as to improve the flame resistance of the composite material remarkably, and a flame resistance level of UL94 5-V is obtained. According to the preparation method of the nylon composite material, the nylon 66 and the nylon 6 are served as the foundational resin and compounded with the fire retardant, wherein particularly the bromination styrene and the antimony chemical compound are served as the fire retardant so as to improve the flame resistance of the composite material remarkably, and a flame resistance level of UL94 5-V is obtained.

Description

technical field [0001] The invention belongs to the field of plastics, and in particular relates to a nylon composite material, its preparation method and application. Background technique [0002] PA66 (polyamide 66 or nylon 66) is a translucent or opaque milky white crystalline polymer with plasticity. PA66 has a high degree of crystallinity in the PA series. It is characterized by corrosion resistance to acids, alkalis, most inorganic salt solutions, halogenated alkanes, hydrocarbons, esters, ketones, etc. It also has excellent wear resistance, self-lubricating properties, and high mechanical strength. At present, pure nylon 66 flame retardant material glow wire can only achieve 1.6mm UL94V-0 grade. [0003] PA6 (polyamide 6 or nylon 6) is a translucent or opaque milky white semi-crystalline polymer, which is characterized by excellent thermodynamic properties, light weight, good toughness, good chemical resistance and durability, and good wear resistance , Self-lubric...
