Abstract

The invention relates to a polyphthalamide material as well as a preparation method and application thereof. The polyphthalamide material comprises the following components in parts by mass: 45-55 parts of polyphthalamide; 4-6 parts of an inorganic synergistic flame retardant; 12 to 18 parts of a halogen fire retardant; 28-32 parts of a functional short fiber combination; 0.9 to 1.1 parts of an auxiliary agent; wherein the functional short fiber combination is composed of enhanced short fibers and conductive short fibers. Thus, by adopting the synergistic effect of the components, high temperature resistance, UL94 V0-level flame retardance, electric conduction and electromagnetic interference resistance are integrated at the same time, the mechanical property is excellent, and the technical problems that in an existing polyphthalamide modification technology, single-function modification cannot meet the requirements of multiple scenes, and the mechanical property is seriously degraded due to superposition of multiple properties are effectively solved.
