Embodiment 1

[0043] First, at room temperature, add 1000mL of ethanol and 10mL of water into a 2L three-necked flask, stir and mix, then pass through nitrogen, and add 100g of I-type ammonium polyphosphate and 18g of ethylenediamine under nitrogen atmosphere, stir and heat up to 70°C, After reacting for 2 hours, wash with ethanol and dry. Its yield was 88%.

Embodiment 2

[0045] First, at room temperature, add 1000mL of ethanol and 40mL of water into a 2L three-necked flask, stir and mix, then pass through nitrogen, and add 100g of I-type ammonium polyphosphate and 18g of ethylenediamine under nitrogen atmosphere, stir and heat up to 70°C, After reacting for 2 hours, wash with ethanol and dry. Its yield is 90%.

Embodiment 3

[0047] First, at room temperature, add 1000mL methanol and 200mL water into a 2L three-necked flask, stir and mix, then pass through argon, and add 100g I-type ammonium polyphosphate and 18g ethylenediamine under argon atmosphere, stir and heat up to 70 ℃, after reacting for 2 hours, wash with ethanol and dry. Its yield was 78%.

Abstract

The invention discloses organic amine modified ammonium polyphosphate. Organic amine modified ammonium polyphosphate is prepared through an ionic reaction between organic amine and ammonium polyphosphate. The structure formula is shown in the description, wherein the R of the formula is a straight chain alkyl or branch chain alkyl with a carbon number between 2 and 6, and the n is not smaller than 1. The invention also discloses a preparation method and applications of organic amine modified ammonium polyphosphate. The organic amine modified ammonium polyphosphate is obtained through modifying ammonium polyphosphate by organic amine in water and alcohol solution, is capable of being used alone as the expanding flame-retardant agent, is harmless to human bodies, can obtain excellent flame-retardant effects by mixing with polypropylene, polyethylene and epoxy resin, and the preparation process is pollution free.

Description

technical field [0001] The invention belongs to the technical field of ammonium polyphosphate and its preparation and application, and in particular relates to an organic amine-modified ammonium polyphosphate and its preparation method and application. Background technique [0002] Although high molecular polymers have been widely used due to their good properties, such as electrical insulation, chemical stability, and good processing properties, their flammability limits their application in a wider range of fields, such as electronics Devices, flame-retardant protective clothing and military uniforms, textiles in vehicles, decorative fabrics in high-rise hotels, etc. In order to expand the application range of high molecular polymers, in recent decades, scientific and technological workers have developed various flame retardants and applied them to the flame retardancy of high molecular polymers. Among them, intumescent flame retardants are a kind of environmentally frien...
