Embodiment 1

[0028] Add commercially available concentrated ammonia (25%-28%) and water equal to the volume of ammonia to a four-necked flask equipped with a stirrer, a solid feeder, a thermometer, a reflux condenser, and a gas absorption device, and then add monoallyl The base amine was stirred to form a homogeneous solution and cooled to 0-5°C. Under vigorous stirring, add cyanuric chloride solid in batches, and keep the temperature of the reaction system below 10°C during the whole addition process; after the addition is complete, continue to stir and react for 1 hour; raise the temperature to 45-55°C, and keep it at this temperature React for 2 hours; heat up to 90°C, and keep at this temperature for 4 hours; after the reaction, filter, wash, and dry to obtain the monoallyl-substituted melamine (hereinafter referred to as cyanuric chloride, allylamine and ammonia water) The reaction molar ratio is 1:1:5.5.

Embodiment 2

[0030] Add commercially available concentrated ammonia (25%-28%) and water equal to the volume of ammonia to a four-necked flask equipped with a stirrer, a solid feeder, a thermometer, a reflux condenser, and a gas absorption device, and then add N-formazan Stir allyl amine to form a homogeneous solution, cool to 0-5°C; under vigorous stirring, add cyanuric chloride solid in batches, and keep the temperature of the reaction system below 10°C during the entire addition process; after the addition is complete, continue Stir the reaction for 2 hours; raise the temperature to 45-55°C, and keep it at this temperature for 4 hours; raise the temperature to 92°C, and keep it at this temperature for 5 hours; after the reaction, filter, wash, and dry to obtain the product-N -Methyl-N-allyl-melamine (hereinafter referred to as ABR-2); the reaction molar ratio of cyanuric chloride, allylamine and ammonia water is 1:1:5.8.

Embodiment 3

[0032] Add commercially available concentrated ammonia (25%-28%) and water equal to the volume of ammonia to a four-necked flask equipped with a stirrer, a solid feeder, a thermometer, a reflux condenser, and a gas absorption device, and then add diallyl Stir the base amine to form a homogeneous solution, cool to 0-5°C, add cyanuric chloride solid in batches under vigorous stirring, and keep the temperature of the reaction system below 10°C during the entire addition process; after the addition is complete, continue to stir and react for 2 hour; be warmed up to 45-55 ℃, and keep at this temperature for 4 hours; be warmed up to 95 ℃, and keep at this temperature for 4 hours; Diallyl melamine (hereinafter referred to as ABR-3); the reaction molar ratio of cyanuric chloride, allylamine and ammonia water is 1:1:6.

Abstract

The invention discloses a fire retardant containing an allyl substituted triazine carbon-forming agent and a preparation method of the fire retardant. The intumescent fire retardant is prepared from the allyl substituted triazine carbon-forming agent capable of cross-linking with high molecular resin, ammonium polyphosphate or coated ammonium polyphosphate, and a cross-linking agent. The allyl substituted triazine carbon-forming agent capable of cross-linking with the high molecular resin is prepared from raw materials of cyanuric chloride, allyl amine and ammonia water through a substitution reaction in a aqueous solution; the fire retardant has the characteristics that the raw materials are obtained easily, continuous production is performed conveniently, organic solvents are not used, the yield is high and the like. The carbon-forming agent has an air source unit and a carbon source unit; when being used, the carbon-forming agent is matched with an acid source and integrally combined with the resin by the cross-linking agent; the shortage that the three components of the intumescent fire retardant are dispersed unevenly in a base body and easy to migrate and separate out is overcome; the fire retardant is high in heat stability and capable of being used in the majority of high molecular materials, and has good application prospect.

Description

technical field [0001] The invention relates to the technical field of flame retardant applications, in particular to a flame retardant containing an allyl-substituted triazine carbon forming agent and a preparation method thereof. Background technique [0002] With the wide application of polymer materials in life and engineering production, people's flame retardant requirements for polymer materials are also increasing. Halogenated flame retardants are currently the largest and most widely used flame retardants in the world. However, with the enhancement of environmental protection awareness, people have gradually realized the hazards of halogenated flame retardants, and gradually developed low-toxicity, low-toxicity A new flame retardant that is smoke-free and halogen-free. Among them, intumescent flame retardants have become one of the important research directions of halogen-free flame retardants in recent years due to their advantages of low toxicity, smoke suppressio...
