Embodiment Construction
[0010] A certain amount of ethylene glycol (C 2 H 6 O 2 ), then equimolar 2-carboxyethylphenylphosphoric acid (C 9 H 11 O 1 P) Pour into ethylene glycol solvent, then add a certain amount of catalyst, stir, heat, and heat up to 250 ° C, while maintaining the pressure at the level of -0.8Mpa (vacuum), start timing from reflux, and react after 1.5 hours After the end, the light yellow liquid flame retardant is obtained, and then the temperature is rapidly lowered to 20 °C, and the material is discharged and canned in plastic drums. The storage and transportation temperature is 20-25 °C.

Abstract
A non-halogen fire retardant for terylene polymer chips used to prepare polyester fibres is prepared from ethanediol (C2H6O2) and 2-carboxyethyl phenylphosphoric acid (C9H11O4P) through adding catalyst, stirring, heating, negative-pressure reaction, and cooling.
Description
technical field [0001] The invention relates to a phosphate ester chemical auxiliary suitable for flame retardant modification of polyester polyester and a production process thereof, in particular, it has the characteristics of halogen-free environmental protection, permanent flame retardant and simple process. Background technique [0002] At present, the polyester polyester flame retardant modifiers used in the market mainly include traditional additive flame retardants, post-finishing flame retardants and other new flame retardants. Traditional additive flame retardants are often washed 4-5 times, and the flame retardant effect will be reduced or completely lost. Although flame retardant finishing agents can also obtain durable flame retardant effects, because such flame retardant finishing agents must be impregnated, Baking, curing and other processes can fix the flame retardant elements in the fabric by curing, which will have a great impact on the feel and flexibility...
