High-flame-retardant composite material and preparation method thereof

The invention belongs to the technical field of engineering plastics, and particularly relates to a high-flame-retardant composite material and a preparation method thereof. The composite material comprises the following components: long-carbon-chain semi-aromatic nylon, a fiber reinforced filler, a flexibilizer, alkyl aluminum phosphinate, nano montmorillonite, a zinc ion ionomer, a coupling agent, a lubricant and an antioxidant. Alkyl aluminum phosphinate is used as a main flame retardant, and nano-montmorillonite and a zinc ion ionomer are used as auxiliary flame retardants. The nano-scale montmorillonite has certain adsorption performance, and can prevent the alkyl aluminum phosphinate flame retardant from being separated out in the processing process. The zinc ion ionomer is easier to disperse in a long-carbon-chain semi-aromatic nylon resin matrix relative to alkyl aluminum phosphinate and nano-montmorillonite, and ion groups contained in the zinc ion ionomer can generate an ionic crosslinking effect with ions in alkyl aluminum phosphinate and nano-montmorillonite, so that the mechanical property and the thermal stability of the composite material are improved; and moreover, the melt viscosity is improved, and the molten drop phenomenon during combustion is prevented.
