Abstract

The present invention discloses fire retardation, filling and modifying PBT powder and a preparation method thereof, wherein the fire retardation, filling and modifying PBT powder comprises, by mass, 50-80% of PBT, 10-15% of a fire retardation agent, 5-20% of a filler, 2-6% of a compatibilizer, 0.5-2% of a stabilizer, 0.1-0.5% of an antioxidant, and 0.1-1% of pentaerythrityl tetrastearate, wherein the filler is a composite filler formed from 50 wt% of heavy calcium carbonate, 25 wt% of precipitated barium sulfate, 20 wt% of nanometer montmorillonite, and 5 wt% of an aluminum titanium composite coupling agent. The fire retardation, filling and modifying PBT powder of the present invention has beneficial effects of high fire retardation, high strength, high heat resistance, low cost, good aging resistance, stable size, excellent electrical property, excellent processability, and the like, and provides good application prospects in the fields of electronic appliances, vehicles, machinery, chemical industry, and the like, wherein the fire retardation performance can achieve the UL94V-0 grade, and the halogen-free environmental protection requirements can be met.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant filled modified PBT powder and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is a crystalline thermoplastic engineering plastic with excellent comprehensive properties and wide applications, but pure PBT materials have disadvantages such as poor flame retardancy, high brittleness, and low notched impact strength. , which will greatly limit its scope of application. Contents of the invention [0003] The object of the present invention is to provide a kind of high flame-retardant, high-strength, low-cost flame-retardant filled modified PBT powder and its preparation method. [0004] The technical solution adopted by the present invention to solve the technical problem is: a kind of flame retardant filled modified PBT powder, its components are proportioned by mass percentage: 50%-80% of PBT, 10%-15% of f...
