Embodiment 1

[0026] Dissolve 10 g of tributylmethylammonium chloride and 0.2 mol of zinc acetate in 250 mL of ethanol, and stir evenly to obtain a colorless and transparent zinc acetate-ionic liquid alcohol solution. Dissolve 30 g of phytic acid (50% aqueous solution) in 150 mL of ethanol, stir evenly to obtain a phytic acid water-ethanol solution, place the solution in a constant pressure dropping funnel, and slowly add it dropwise to the zinc acetate-ionic liquid ethanol solution , a white precipitate will be produced during the dropwise addition. After the dropwise addition, the stirring reaction was continued for 2 h, and the mechanical stirring speed was maintained at 450 r / min. After the reaction was completed, a white suspension was obtained, which was placed in an oven at 80°C for 24 hours, and the suspension was layered. The upper layer was a colorless and transparent clear liquid, and the lower layer was a white precipitate. Wash the precipitate 5 times with deionized water and ...

Embodiment 2

[0028] The ionic liquid functionalized nickel phytate was prepared, and other processes were the same as those in Example 1.

Embodiment 3

[0030] The ionic liquid functionalized cobalt phytate was prepared, and the remaining processes were the same as those in Example 1.

Abstract

The invention relates to a flame retardant preparation technology, and belongs to the field of inorganic chemistry and composite materials. The invention discloses a phytate composite flame retardantfor polyamide and a preparation method of the phytate composite flame retardant. The phytate composite flame retardant comprises phytate functionalized by ionic liquid, ammonium polyphosphate and pentaerythritol; and after the flame retardant is mixed with polyamide, the mass fractions of the phytate functionalized by the ionic liquid, the ammonium polyphosphate and the pentaerythritol in the polyamide blend are respectively 0.1%-5%, 5%-25% and 1%-5%. The composite flame retardant disclosed by the invention is low in cost, simple in preparation method and excellent in polyamide flame-retardanteffect.

Description

technical field [0001] The invention relates to a preparation technology of a flame retardant, belonging to the fields of inorganic chemistry and composite materials. Background technique [0002] Polyamide has good mechanical properties and processing properties, and is widely used in electronic communications, textiles, chemical manufacturing and other fields. However, as a flammable polymer material, polyamide is very easy to cause fire, and its flame retardancy can be improved by adding flame retardant to polyamide. In recent years, people's awareness of environmental protection and safety has been continuously strengthened, and it is of great significance to develop environmentally friendly flame retardants. Intumescent flame retardant is a kind of green and environmentally friendly flame retardant, which has the advantages of low smoke, low toxicity, halogen-free and so on. Intumescent flame retardant (IFR) is a composite flame retardant that generally contains three...
