Embodiment 1

[0025] Put 15.0wt% magnesium hypophosphite, 8.0wt% melamine cyanurate (MCA), 5.0wt% ABS grafted glyceryl methacrylate, and 0.5% antioxidant into a pulverizer and mix evenly to obtain a compounded The flame retardant modifier is mixed evenly with 71.5wt% ABS, put into a twin-screw extruder, melt-extruded at 180-200°C, and cooled to pelletize. The LOI of the obtained phosphorus-based synergistic flame-retardant ABS material is 26.5%, and the UL94 vertical combustion level is V-0.

Embodiment 2

[0027] Put 20.0wt% aluminum hypophosphite, 4.0wt% melamine cyanurate, 4.0wt% ABS grafted glycerol methacrylate, 0.5wt% antioxidant (0.25wt% 1010 and 0.25wt% 168) into the pulverizer After being uniformly pulverized in medium to prepare a compound flame retardant modifier, and then mixed with 71.5.0wt% ABS uniformly, put it into a twin-screw extruder, melt and extrude at 180-200°C, and cool and granulate. The LOI of the obtained phosphorus-based synergistic flame-retardant ABS material is 27.0%, and the vertical combustion rating is UL94V-0.

Embodiment 3

[0029] Put 22.0wt% aluminum diethyl hypophosphite, 2.0wt% dimethylsiloxane, 2.0wt% ethylene-methacrylate-glycidyl methacrylate copolymer, and 0.5% antioxidant into the pulverizer After mixing evenly, a compound flame retardant modifier is prepared, and then mixed evenly with 73.5.0wt% polylactic acid, put into a twin-screw extruder, melt and extrude at 180-200°C, and cool and granulate . The LOI of the obtained phosphorus-based synergistic flame-retardant ABS material is 27.0, and the UL94 vertical combustion level is V-0.

Abstract

The invention discloses a phosphorus-based synergistic flame-retardant ABS composite material, which is characterized in that ABS resin is 50.0-90.0wt%, phosphorus-based flame retardant is 5.0-40.0wt%, nitrogen-based flame retardant is 0.0-30.0wt%, and silicon-based The synergist is 0.0-10.0wt%, the compatibilizer is 0.5-20.0wt%, and the antioxidant is 0.5-1.0wt%, and the above components are all percentages by weight. The invention provides a phosphorus-based synergistic halogen-free flame-retardant ABS composite material, which uses a phosphorus-based flame retardant in conjunction with a nitrogen-based or silicon-based synergist, and adopts a preparation method of melt blending and extrusion. On the one hand, it can overcome the shortcomings of low flame retardant efficiency of flame retardant ABS materials, improve the flame retardant efficiency of flame retardant ABS materials, and improve the mechanical, processing and other physical properties of halogen-free flame retardant ABS composite materials; on the other hand, it can reduce combustion The amount of toxic gas released during the process, low smoke and less toxicity, is an environmentally friendly flame retardant material.

Description

technical field [0001] The invention belongs to a halogen-free flame-retardant ABS material, and in particular relates to a phosphorus-based synergistic flame-retardant ABS composite material. Background technique [0002] ABS resin is a blend of acrylonitrile-butadiene-styrene copolymer or acrylonitrile / styrene copolymer and styrene / butadiene copolymer, the English name is Acrylonitrile-Butadiene-Styrene (ABS), it It is a mixture of butadiene graft copolymer and acrylonitrile-styrene copolymer, in which acrylonitrile accounts for 15%-35%, butadiene accounts for 5%-30%, and styrene accounts for 40-60%. As the ratio of the three components changes, the physical and mechanical properties of the ABS resin change accordingly. ABS resin is a thermoplastic polymer material with high strength, good toughness, heat resistance, low temperature resistance, chemical corrosion resistance, excellent mechanical strength and electrical properties, and easy processing and molding. ABS is ...
