High-heat and high-shear-resistant high-flame-retardant halogen-free flame-retardant compound system and use

Abstract

The present invention discloses a high-heat and high-shear-resistant high-flame-retardant halogen-free flame-retardant compound system and use thereof in a glass fiber reinforced material. The flame-retardant compound system comprises the following components in weight percentages: 40%-99.9% of aluminum diethylphosphinate, 0.1%-50% of a poly/mono-phosphorous acid-condensed diphosphite salt and/or a condensed diphosphite salt, 0-40% of inorganic aluminum phosphite, and 0-10% of a zinc-containing thermally stable compound, wherein the poly/mono-phosphorous acid-condensed diphosphite salt and the condensed diphosphite salt has a structural formula shown in a formula (I): wherein, x is an integer of 0-6, n, y, and p are integers of 1-4, and M is Ca, Mg, Al, Zn, Fe, Sn or Ti.
