Embodiment 1

[0030] The synthetic method of melamine salt of 2-carboxyethylphenylphosphinic acid

[0031]

[0032] In a 1000mL flask equipped with a mechanical stirrer, a thermometer, and a reflux condenser, add 23.5g (0.11mol) of CEPPA and 400mL of distilled water, stir to dissolve it completely, and then add 12.6g (0.1mol) of melamine to the flask Control the reaction temperature with 500mL distilled water at 80°C, and the reaction time is 4h. After the reaction was completed, it was cooled and filtered, washed and filtered repeatedly with distilled water, and air-dried at 80° C. for 12 hours to obtain CEPPAME as a white solid powder with a yield of 86%.

Abstract

The invention relates to a novel phosphorus-based flame retardant and halogen-free intumescent anti-flaming ABS (Acrylonitrile Butadiene Styrene) resin containing the same. Organic phosphinate (2-carboxyethyl phenyl melamine phosphinate) is selected as a main body of the flame retardant, the novel phosphorus-based flame retardant has the advantages of white color, less addition amount, good mechanical performance, low smoke density, good flame-retardant performance and the like, and the high-efficiency flame-retardant effect can be obtained in both condensed phase and gas phase; meanwhile, polyamide 66, poly terephthaloyl ethylene diamine and the like are added as charring agents, so that charring of the ABS resin in combustion is promoted; meanwhile, synergistic agents-organic modified montmorillonoid, rare-earth metal oxide and the like are also added, so that the flame-retardant effect is enhanced; the influence on mechanical property of the halogen-free intumescent anti-flaming ABS resin is smaller while higher flame-retardant level is obtained.

Description

technical field [0001] The invention belongs to the technical field of environmentally friendly flame-retardant ABS resins, and relates to a phosphorus-based flame retardant, in particular to a phosphorus-based flame retardant compounded with 2-carboxyethylphenylphosphinic acid and melamine salt and containing the flame retardant Halogen-free intumescent flame-retardant ABS resin. Background technique [0002] ABS resin is a general-purpose thermoplastic engineering plastic. It is a heterogeneous block copolymer formed by terpolymerization of acrylonitrile, butadiene and styrene. It has high impact strength, good processing performance and chemical stability, easy to mold, the product is glossy, and has both toughness and flexibility. It is widely used in the automotive industry, electronic and electrical industries, light industrial appliances, textiles and construction and other fields. my country is a big consumer of ABS resin, accounting for about 60% of the world's t...
