preparation example Construction

[0034] The present invention provides a kind of preparation method of described 2,4,6-tris(dimethyl phosphate amino group)-1,3,5-triazine-tri-melamine salt, comprising the following steps:

[0035] Carrying out primary heat treatment to the mixture of hexamethylolmelamine and phosphorus oxychloride, and performing secondary heat treatment after heating up to obtain a secondary treatment product;

[0036] The secondary treatment product is dissolved in an inert solvent, followed by atmospheric distillation and vacuum distillation to obtain 2,4,6-tris(phosphoric acid diformyl chloride amino)-1,3,5-triazine solution; the inert solvent is 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, chlorobenzene, nitrobenzene, dimethyl ethylene One or more of sulfone, sulfolane and N,N-dimethylformamide;

[0037] The 2,4,6-tris(phosphoric acid diformyl chloride amino group)-1,3,5-triazine and melamine are hydrolyzed into a salt reaction in water to obtain 2,4,6-tris(dime...

Embodiment 1

[0057] 10g of hexamethylolmelamine and 60.08g of phosphorus oxychloride (molar ratio 1:12) were stirred and reacted in a 150ml three-necked flask. The feeding process is to first add phosphorus oxychloride in an oil bath at 45°C. After the temperature is stable, add hexamethylolmelamine in 12 times, about 0.8g each time. After each addition, wait until the liquid in the bottle is clear and the temperature drops to 45°C. For the next addition, the temperature was maintained at 45°C, and the total addition time was two hours. After the addition, the temperature was kept at 50° C., and the reaction was carried out for 1 hour. Then, raise the temperature to 80°C (heating time is half an hour) and keep it for 5 hours. At this time, the bottle is a colorless transparent liquid, that is, 2,4,6-tris(phosphoric acid diformyl chloride amino)-1,3, 5-triazine.

[0058] The obtained 2,4,6-tris(phosphodiformylchloroamino)-1,3,5-triazine was dissolved in dimethyl sulfoxide. Then change to...

Embodiment 2

[0064] Hexamethylolmelamine and phosphorus oxychloride (molar ratio 1:3) were stirred and reacted in a 150ml three-necked flask. The feeding process is to first add phosphorus oxychloride in an oil bath at 45°C, and then add hexamethylolmelamine in 12 times after the temperature is stable. At 50°C, the total addition time was two hours. After the addition was complete, the temperature was kept at 45° C., and the reaction was carried out for 1 hour. Then, raise the temperature to 75°C (heating time is half an hour) and keep it for 5 hours. At this time, the bottle is a colorless transparent liquid, that is, 2,4,6-tris(phosphoric acid diformyl chloride amino)-1,3, 5-triazine.

[0065]The obtained 2,4,6-tris(phosphodiformylchloroamino)-1,3,5-triazine was dissolved in 1,1,1-trichloroethane. Then change to a distillation device, 125 ℃ oil bath distillation (heating up for half an hour, distillation for half an hour), until basically no fractions are distilled out, and then coole...

Abstract

The invention provides 2,4,6-tri(dimethyl phosphate amido)-1,3,5-triazine-tri-melamine salt and a preparation method and an application thereof. The method employs novel processes of dispersing dissolution of an inertia solvent, acidity control, and solvent washing, which solves the problem of easy partial hydrolysis of phosphatide dur to a structure factor. The embodiment result shows that the 2,4,6-tri(dimethyl phosphate amido)-1,3,5-triazine-tri-melamine salt can be successfully prepared by the method of the invention. The product as a fire retardant for being used in materials of PE, PP and PU has excellent flame retardation performance, and the oxygen index is 22.3-28.5%. In addition, with increase of addition of the 2,4,6-tri(dimethyl phosphate amido)-1,3,5-triazine-tri-melamine salt, the oxygen indexes of PE, PP and PU doped with 2,4,6-tri(dimethyl phosphate amido)-1,3,5-triazine-tri-melamine salt during flame retardation are increased.

Description

technical field [0001] The invention relates to the technical field of organic compound synthesis, in particular to 2,4,6-tris(dimethylphosphorylamino)-1,3,5-triazine-tri-melamine salt and its preparation method and application. Background technique [0002] In our country, there are more than 100 kinds of flame retardant products. Among them, halogenated flame retardants are one of the organic flame retardants with the largest output in the world. They have the advantages of less dosage, high flame retardant efficiency and wide adaptability, but they generate a lot of smoke and are toxic and corrosive when burned. gas. [0003] In recent years, as the non-halogenated requirements of flame retardant materials have become more and more urgent, domestic and foreign technicians have been adjusting the product structure of flame retardants, and the development of halogen-free flame retardants to replace halogen flame retardants has become the development trend of flame retardan...
