Embodiment 1
[0027] The specific preparation process of flame retardant glue is as follows:
[0028] Step 1: Add 414g of p-methoxybenzyl alcohol into 2L of ether, mix well and heat up to 50-60°C, then add 94.08g of phosphoric acid dropwise to it, heat up to 85-90°C after the addition is complete, and reflux for 5- 6h, then the product was washed with saturated sodium chloride and then added in ethyl acetate to extract, and the obtained oil phase was subjected to vacuum distillation to obtain product A; wherein p-methoxybenzyl alcohol and phosphorus pentoxide were in a molar ratio of 3: 0.48-0.49 ratio mixing;
[0029] Step 2: Add 1kg of the product A prepared in step 1 to 25mL of 33-35% hydrogen bromide acetic acid solution, heat up to 100-120°C for reflux reaction for 10-12h to obtain a viscous product, and wash the product with saturated chlorine After washing with NaCl, adding acetone for extraction, and then subjecting the obtained oil phase to vacuum distillation to obtain product B;...

[0033] The specific preparation process of flame retardant glue is as follows:
[0034] Step 1: Add 276g of p-methoxybenzyl alcohol into 2L of ether, mix well and heat up to 50-60°C, then add 94.08g of phosphoric acid dropwise to it, heat up to 85-90°C after the addition is complete, and reflux for 5- 6h, then the product was washed with saturated sodium chloride and extracted by adding ethyl acetate, and the obtained oil phase was subjected to vacuum distillation to obtain product A;
[0035] Step 2: Add 1kg of the product A prepared in step 1 to 25mL of 33-35% hydrogen bromide acetic acid solution, heat up to 100-120°C for reflux reaction for 10-12h to obtain a viscous product, and wash the product with saturated chlorine After washing with NaCl, adding acetone for extraction, and then subjecting the obtained oil phase to vacuum distillation to obtain product B;
[0036] Step 3: Add 1kg of the product B prepared in step 2 to 20L of acetone, raise the temperature to 50-60°C,...
