Problems solved by technology

However, the limiting oxygen index of ABS resin is about 18. It is a flammable material, and there is still a phenomenon of molten dripping, which has a large safety hazard. Therefore, it is limited in application. Flame-retardant modified ABS resin has a large Practical significance
[0003] Currently commonly used ABS resin flame retardants are additive type and reactive type. Halogenated flame retardants, especially bromine-containing flame retardants compounded with antimony trioxide, have a good flame retardant effect on ABS, but due to flame retardants It has been banned by the European Union due to its own environmental problems, so it has become an industry trend to study environmentally friendly halogen-free flame-retardant ABS

Abstract

The invention discloses a special environmental-friendly halogen-free flame retardant for ABS (acrylonitrile butadiene styrene) resin. The flame retardant consists of aluminum hypophosphite as a main flame retardant and auxiliary flame retardants. The flame retardant can completely replace antimony bromide flame retardants and has the performance of better flame retardance, low smoke, low corrosion, good carbon formation performance, no toxicity and the like; in addition, when the flame retardant is applied to ABS, hydroplaning phenomenon cannot occur during extrusion processing, and no molten dripping phenomenon exists after combustion; and in addition, the cost is low.

Description

technical field [0001] The invention relates to a halogen-free phosphorus-based environment-friendly flame retardant, that is, aluminum hypophosphite. The flame retardant is compounded with other auxiliary flame retardants and is specially used for flame retardant of ABS resin. Background technique [0002] ABS resin is a class of engineering plastics with excellent performance. Because of its high impact strength, excellent stability, electroplating performance, electrical insulation, processing performance and heat resistance, it is widely used in auto parts, electronic and electrical housings, Industrial accessories, etc. However, the limiting oxygen index of ABS resin is about 18. It is a flammable material, and there is still a phenomenon of molten dripping, which has a large safety hazard. Therefore, it is limited in application. Flame-retardant modified ABS resin has a large Practical significance. [0003] Currently commonly used ABS resin flame retardants are addi...
