Embodiment

[0037] see Figure 1-10 , the present invention provides a technical solution:

[0038] A preparation method of a biomass-based environmentally friendly flame retardant PD agent flame-retardant finishing fabric, the specific steps of the preparation method of the biomass-based environmentally friendly flame retardant PD are as follows:

[0039] S1: Add 0.1 mol of phytic acid aqueous solution and 0.6 mol of dicyandiamide to a 250 ml three-necked flask in sequence to obtain a mixed reaction solution;

[0040] S2: heating the mixed reaction liquid obtained in step S1 to 130° C. under magnetic stirring, condensing and refluxing for 2 hours to obtain a light yellow transparent viscous crude product liquid;

[0041] S3: Precipitate the crude product liquid in step S2 with absolute ethanol and acetone, suction filter, wash, remove unreacted reactants, and dry with a freeze dryer at -50°C and 8pa to obtain a white solid flame retardant PD .

Abstract

The invention belongs to the technical field of environmental protection and flame retardance, and particularly relates to a biomass-based environment-friendly flame retardant PD flame-retardant finished pure cotton fabric and a preparation method thereof. The raw materials of the biomass-based environment-friendly flame retardant PD flame-retardant finished fabric are prepared from a flame retardant PD and a cotton fiber fabric; the flame retardant PD is synthesized by reacting biomass phytic acid and dicyandiamide; and the PD flame-retardant finished fabric is obtained by rolling and baking a flame retardant PD and the cotton fiber fabric. The synthesis method is simple, environment-friendly and pollution-free, and EDS and infrared analysis test results show that PD is a multi-active phosphorus-nitrogen flame retardant; the fabric subjected to PD flame-retardant finishing has better thermal stability and char forming property, and PD has a phosphorus-nitrogen synergistic flame-retardant effect, is excellent in flame-retardant property and better in washability, and can be used as an environment-friendly washable flame retardant for pure cotton fabrics; and PD flame-retardant finishing has small influence on the whiteness and breaking strength of the fabric.

Description

technical field [0001] The invention relates to the technical field of environment-friendly flame retardants, in particular to a kind of biomass-based environment-friendly flame retardant PD flame-retardant finishing fabric and a preparation method thereof. Background technique [0002] Pure cotton fabric has excellent wearing performance and is an important textile fabric favored by consumers. However, cotton fibers are flammable, and the limiting oxygen index is only 18.3%, so highly flammable cotton fabrics have potential safety hazards for consumers. [0003] Commonly used elements for flame retardant effect are: phosphorus, nitrogen, halogen, boron, silicon, sulfur, aluminum, magnesium, etc. At present, the commonly used flame retardants are mainly phosphorus-based compounds and halogen-containing halides. Halides are effective flame retardants, but the combustion of such flame retardants will release harmful and corrosive gases such as hydrogen halides, endangering p...
