Document Type and Number:
WIPO Patent Application WO/2023/168791
Kind Code:
A1
Abstract:
A halogen-free flame retardant composition and an application thereof in flame retardancy of glass fiber reinforced engineering plastics. The composition of the halogen-free flame retardant composition comprises, in mass percent: 1%-99% of a phosphorus-containing aluminum salt complex based on aluminum methyl butyl phosphinate, 1%-99% of aluminum phosphite and/or a derivative thereof, 0-80% of aluminum diethylphosphinate, 0-40% of a nitrogen-containing compound, and 0-20% of a zinc salt thermally-stable compound. The halogen-free flame retardant composition is applied to flame retardancy of glass fiber reinforced engineering plastics, and has a low molding shrinkage characteristic; and a halogen-free flame retardant glass fiber reinforced engineering plastic prepared by using the halogen-free flame retardant composition can meet the UL94V-0 flame retardant standard.
