Embodiment 1

[0027] A preparation method of phytic acid furanamine flame retardant, the steps are:

[0028] (1) 1mol of phytic acid and 6mol of furanamine Dissolved in 1000mL and 2000mL of ethanol respectively, the two solutions were mixed and reacted at 0°C for 1 h and then centrifuged to obtain the crude product of phytate furanamine;

[0029] (2) Centrifuge and wash 3 times with ethanol until pH=7 and no change, then wash with ethanol for several times, then vacuum dry at 50° C. for 24 hours to obtain phytic acid furanamine flame retardant, denoted as PAF1.

Embodiment 2

[0031] A preparation method of phytic acid furanamine flame retardant, the steps are:

[0032] (1) 1mol of phytic acid and 12mol of furanamine Dissolved in 1000mL and 2000mL of ethanol respectively, the two solutions were mixed and reacted at 0°C for 8h and then centrifuged to obtain the crude product of phytate furanamine;

[0033] (2) Centrifuge and wash with ethanol for 2 to 3 times until pH=7 and no change, then wash with ethanol for several times, and then vacuum dry at a temperature of 80°C for 24 hours to obtain a phytic acid furanamine flame retardant, denoted as PAF2 .

Abstract

The invention discloses a modified flame retardant polyester material containing a full bio-based flame retardant and a preparation method thereof, belonging to the field of flame retardant materials. The preparation method of the phytic acid furanamine salt flame retardant is as follows: the ethanol solution of phytic acid and the ethanol solution of furanamine are mixed at 0-4° C. to obtain a suspension; the unreacted substances are removed by centrifugation, and after washing with ethanol for 2-3 times, After drying, the phytic acid furanamine salt flame retardant is obtained. Preparation method of flame retardant polyester material: 100 parts of polyester and 0.5-3 parts of phytic acid furanamine flame retardant are prepared by melt-blending at a processing temperature of 150-180°C. The invention prepares the flame retardant from biological sources, is green and environmentally friendly, has obvious flame retardant effect of the composite material, and effectively expands the application range of each auxiliary agent and material.

Description

technical field [0001] The invention belongs to the field of flame retardant materials, in particular to a preparation method of a full bio-based flame retardant and a modified flame retardant polyester material. Background technique [0002] Polyester is a polymer material with excellent performance and has a very wide range of applications, but its flammability limits the use of polyester in many occasions, so how to improve the flame retardancy of polyester materials is particularly important. Flame retardants are an effective way to improve the flame retardant properties of materials. Currently used flame retardants include halogen-based, phosphorus-nitrogen-based, inorganic flame retardants, and the like. Halogen-based flame retardants have been gradually banned due to the release of toxic and harmful gases when burning; although inorganic flame retardants can achieve good flame retardant properties, they have the disadvantages of large additions, easy precipitation, p...
