Embodiment 1

[0032] A kind of preparation method of phosphaphenanthrene and polyphosphazene double base synergistic flame retardant acrylonitrile-butadiene-styrene copolymer composite material, comprises the following steps:

[0033] S1, the acrylonitrile-butadiene-styrene copolymer of 90kg, the vapor phase flame retardant of 2.5kg, the condensed phase flame retardant of 2.5kg, the compatibilizer of 5kg and the antioxidant of 0.5kg are in 80 After drying at °C, mix well to obtain a mixture. The drying time is 1-4 hours, until there is no obvious moisture.

[0034] S2. Blending and extruding the mixture in step S1 through a twin-screw extruder at 210-235° C., followed by cooling to room temperature, followed by hauling and pelletizing to obtain polylactic acid, phosphaphenanthrene and polyphosphorus Nitrile double base synergistic flame retardant composite material.

[0035] Described vapor phase flame retardant is reactive type phosphaphenanthrene, (DOPO) 2 -P-PPD-PH), the structure of ...

Embodiment 2

[0042] The difference with embodiment 1 is: in step S1, gas phase flame retardant gets 1.5kg, and condensed phase flame retardant gets 1.5kg.

Abstract

The invention belongs to the field of acrylonitrile-butadiene-styrene copolymer composite materials, and particularly relates to a phosphaphenanthrene and polyphosphazene double-base synergistic flame-retardant acrylonitrile-butadiene-styrene copolymer composite material and a preparation method thereof. The phosphaphenanthrene and polyphosphazene double-base synergistic flame-retardant acrylonitrile-butadiene-styrene copolymer composite material is prepared from, by mass, 80 to 95 parts of an acrylonitrile-butadiene-styrene copolymer, 2 to 5 parts of a gas-phase flame retardant, 2 to 5 partsof a a condensed-phase flame retardant, 5 to 10 parts of bulking agent and 0.5 part of an antioxidant. Due to the synergistic effect of the gas-phase flame retardant and the condensed-phase flame retardant, the gas-phase flame retardant is mainly used for gas-phase flame retardance, and the condensed-phase flame retardance is weak. The condensed-phase flame retardant is mainly used as a condensedphase, so that the gas-phase flame retardant is made up; and by mixing the gas-phase flame retardant, the liquid-phase flame retardant and the acrylonitrile-butadiene-styrene copolymer, the flame-retardant material has more excellent flame retardancy and excellent interfacial compatibility, so that the mechanical properties of the polymer flame-retardant material are not reduced and are enhanced.

Description

technical field [0001] The invention belongs to the field of acrylonitrile-butadiene-styrene copolymer composite materials, in particular to a kind of phosphaphenanthrene and polyphosphazene double base synergistic flame-retardant acrylonitrile-butadiene-styrene copolymer composite material and its preparation method. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (Acrylonitrile Butadiene Styrene) is abbreviated as AB, which is a thermoplastic polymer material with high strength, good toughness and easy processing. It is used to prepare various parts such as instruments, electrical appliances, machinery, etc. But acrylonitrile-butadiene-styrene copolymer is easy to burn. Halogenated flame retardants are used in acrylonitrile-butadiene-styrene copolymer resins, mainly polybrominated biphenyl compounds. Flame retardant effect, but halogen-containing flame retardants will emit toxic and corrosive gases and smoke when they are burned or processed at h...
