Problems solved by technology

However, in this case, the thermal decomposition temperatures of triphenyl phosphate (TPP) and melamine cyanate are different from each other, so it is difficult for the flame retardant to exert a good flame retardant performance relative to its dosage.

preparation example Construction

[0026] In the preparation method of the present invention, preferably, step (a) is carried out at a temperature of 0°C to 60°C for 5 to 15 hours, and step (b) is carried out at a temperature of 50°C to 100°C for 5 to 15 hours.

[0027] The alcohol used in step (a) may be selected from methanol, ethanol, propanol and butanol. However, alcohols may include (1) ethanols or (2) methanols in order to control the thermal and migration properties of the product.

[0028] The aminoalcohol used in step (b) may be selected from 2-dimethylaminoethanol, dimethylaminoethanol, 2-dimethylaminocarbinol, and 2-dimethylaminopropanol, and may preferably be 2 -Dimethylaminoethanol.

[0029] In addition, the halide amino salt used in step (b) may be selected from 2-di-chloroethylamine, 2-chloromethylethylamine, di-chloroethylamine and chloromethylethylamine, and may preferably Di-chloroethylamine.

[0030] The present invention also provides a flame retardant resin containing 5 to 50% by weight...

Embodiment 1

[0035] Embodiment 1: the preparation of three-(dimethylaminomethyl) phosphoric acid ester

[0036] At room temperature, 689.7g trichlorophosphate (POCl 3 ) was added to 1,995g of toluene, and then 640.3g of ethanol (C 2 h 5 OH), to generate 492 g of hydrogen chloride (HCl). The hydrogen chloride thus obtained was aged for 5 hours at room temperature and topped with toluene at 140°C for 5 hours, topped under reduced pressure (1 torr) at 110°C for 2 hours, and then filtered to obtain 819.3g initial reaction product triethyl phosphate (C 6 h 15 PO 4 ).

[0037] With the above-mentioned product trimethyl phosphate of 794.7g (C 3 h 9 PO 4 ) was added to 2,168 g of toluene heated up to 110° C. and 10 g of tyzor TBT. The resulting mixture was subjected to solvent reflux topping distillation while mixing dimethylaminocarbinol (C 3 h 9 NO), the dimethylaminocarbinol (C 3 h 9 NO) was added dropwise within 3 hours at 130°C to obtain 603.0g of ethanol (C 2 h 5 OH). Etha...

Abstract

The present invention relates to an amino group-containing phosphate ester flame retardant which has both a phosphate group and an amine group to exhibit a good flame retarding effect while overcoming the problems with the conventional phosphor-based flame retardants not having a good flame retarding effect with respect to its added amount, and a method of preparing the same.

Description

technical field [0001] The present invention relates to phosphoric acid ester flame retardant containing amino group and preparation method thereof, especially relates to a kind of phosphoric ester flame retardant containing amino group, it contains both phosphoric acid group and amino group so as to show good flame retardant performance, overcomes at the same time The problem of poor flame retardancy of conventional phosphorus-based flame retardants relative to their dosage is solved, and the preparation method of the flame retardants is involved. Background technique [0002] Traditionally, organic halogen compounds have been added as flame retardants in order to provide flame retardant properties to resin compositions including thermosetting resins such as epoxy resins, unsaturated polyester resins, phenol resins or melamine formaldehyde resins; And thermoplastic resins such as ABS resin, AS resin, PET resin, PBT resin or PMMA resin. Such a resin composition containing a...
