Embodiment 1

[0029] Step 1: In a 2-liter four-necked round-bottomed flask equipped with a stirrer, a thermometer and a dropping funnel, first add 2 mol of NH 2 NH 2 .H 2 O, 2mol triethylamine and 100ml dichloromethane, then add 1mol at 20°C Then continue to keep warm at 20°C for 10 hours, and finally remove the organic solvent by distillation under reduced pressure to obtain The reaction is an exothermic reaction.

[0030] Step 2: First mix 1mol with 1mol Mix in 100 ml of toluene at 20°C, then stir at 70°C for 10 hours, and finally distill the organic solvent under reduced pressure to obtain where n=125.

[0031] The physical constants of the final product of this embodiment are: 1H NMR (400MHz, CDCl3) δ7.02 (br, 1H), 6.58 (br, 1H), 5.07 (s, 8H).. Infrared spectrum (KBr tablet): 3350 , 2946, 1658, 1430, 918, 824cm-1. Elemental analysis calculated value: C, 31.00; H, 3.78; N, 13.15; found value: C, 31.21; H, 3.89; N, 13.10.

Embodiment 2

[0033] Step 1: In a 2-liter four-necked round-bottomed flask equipped with a stirrer, a thermometer and a dropping funnel, first add 2 mol of NH 2 NH 2 .H 2 O, 2mol triethylamine and 100ml dichloromethane, then add 1mol at 20°C Then continue to keep warm at -20°C for 10 hours, and finally remove the organic solvent by distillation under reduced pressure to obtain The reaction is an exothermic reaction.

[0034] Step 2: First mix 1mol with 1mol Mixed in 100 ml of toluene at 20°C, then stirred at 160°C for 10 hours, and finally distilled the organic solvent under reduced pressure to obtain where n=150.

[0035] The physical constant of present embodiment final product is the same as embodiment 1

Embodiment 3

[0037] Step 1: In a 2-liter four-neck round bottom flask equipped with a stirrer, a thermometer and a dropping funnel, first add 10mol NH 2 NH 2 .H 2 O, 2mol triethylamine and 100ml dichloromethane, then add 1mol at 20°C Then continue to incubate at -20°C for 10 hours, and finally remove the organic solvent and excess NH by distillation under reduced pressure. 2 NH2 .H 2 O get The reaction is an exothermic reaction.

[0038] Step 2: First mix 1mol with 1mol Mixed in 100 ml of toluene at 20°C, then stirred at 160°C for 10 hours, and finally distilled the organic solvent under reduced pressure to obtain n=165.

[0039] . The physical constant of present embodiment final product is the same as embodiment 1

Abstract

The invention discloses a furan bio-based antibacterial and anti-yellowing multifunctional fabric flame retardant containing N-type and P-type polymers as well as a preparation method and application of the flame retardant. The flame retardant has a chemical structural formula as follows: formula (shown in the description), wherein R1 represents H, C1-C6 saturated fatty hydrocarbon and C2-C6 unsaturated alkyl, and R2 represents H, C1-C6 saturated fatty hydrocarbon and C2-C6 unsaturated alkyl. After being processed by virtue of the flame retardant, a cotton fabric simultaneously has flame retardance, antibacterial property and the like, and the flame retardance, the antibacterial property and the whiteness are improved relative to common cotton cloth, so that the flame retardant can be applied to fire-retardant textiles.

Description

technical field [0001] The invention relates to the field of functional finishing of textiles, in particular to a furan bio-based antibacterial and anti-yellowing multifunctional N, P polymer fabric flame retardant and its preparation method and application. Background technique [0002] Polymer materials have many superior properties and are widely used in textiles, electronics, machinery, chemicals, aerospace and other fields. With the improvement of people's awareness of fire prevention and the enhancement of the concept of disaster reduction and disaster prevention, people's requirements for flame retardant materials are getting higher and higher, which makes the development, production, promotion and application of flame retardants develop rapidly. Increasingly, the output has risen sharply. [0003] There are usually two ways to prepare flame-retardant textiles. One is the additive type, that is, the flame retardant is mixed with the spinning dope, so that the spun fa...
