Embodiment 1
[0021] The present invention will be further described in detail below in conjunction with specific examples.
[0022] (1) Synthesis of flame retardant macromolecular functional fillers
[0023] Put 100ml of absolute ethanol as the reaction solution into a 250ml three-necked flask, and with the agitator running (rotating at 280r / min), add 10g of arbutin, 2g of guanidine, and then 1g of sodium bisulfite, and react for 3 hours. Filter, wash with absolute ethanol three times, and place the product in a vacuum oven to dry to obtain a white powder sample;
[0024] ② Put 80ml of a mixed solution of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDC) and N-N-hydroxysuccinimide (NHS) in a 250ml three-necked flask as the reaction solution, In the case of starting the agitator (speed 250r / min), add 8g of the above white powder sample and tartaric acid in total, after stirring for 4 hours, take out the reaction solution, wash with methanol and deionized water for 3-4 times, and place...
