preparation example Construction

[0049] A kind of preparation method of linear flame retardant compound, it is characterized in that: comprise the following steps:

[0050] Step 1: 20-25 parts by mass of polyvinyl alcohol is heated and dissolved in 180-200 parts by mass of N-methylpyrrolidone solvent to form a saturated solvent; then 30-40 parts by mass of phytic acid, 5- 10 parts by mass of catalyst pyridine, and 30-35 parts by mass of water-absorbing agent dicyclohexylcarbodiimide are added to the solution;

[0051] Step 2: Add the solution formed in Step 1 into the oil bath, and stir until it is completely dissolved;

[0052] Step 3: the solution in step 2 is warmed up to 60 degrees Celsius, this temperature can make the reaction better, continue to stir, react for 4 hours, 4 hours can make the reaction larger;

[0053] Step 4: After cooling the solution in step 3 to room temperature, add 90-100 parts by mass of ethanol precipitation agent to precipitate it, and filter to obtain a white product.

Description

technical field [0001] The invention relates to the field of new textile materials, in particular to a linear flame retardant compound and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the demand for home textile products and special fibers is also increasing day by day, and more and more textile products are being promoted in daily life. With that comes some hazards posed by conventional textile products. Common textile materials are combustible materials, which will burn and melt when exposed to heat, which poses a great risk to people's living and working in peace and contentment. [0003] In recent years, a large number of flame-retardant chemical materials such as phosphorus and halogen elements have been developed to make up for the defects of flammability in conventional materials, reduce the harm caused by combustion in various accidents, and improve people's quality of life, The pursuit of...
