Example Embodiment
[0031] The raw materials used in the examples and comparative examples are as follows:
[0032] 【Phosphorus-containing double horse resin】
[0033] A1: It has the structure shown in Formula 1, where X in Formula 1 is the structure shown in Formula 3, R1 and R2 are hydrogen, and R5 and R6 are —CH 2 (CH 2 ) 6 CH 2 —, R7 is —CH 2 (CH 2 ) 6 CH 3 .
[0034] A1 is synthesized according to the following method:
[0035] In a nitrogen atmosphere, mix 0.1 mol tri-n-octyl phosphine oxide and 200 ml 96% sulfuric acid, then cool to -5°C, prepare 14.5g fuming nitric acid / 100ml sulfuric acid solution, add dropwise to the above mixture, 2h later, heat up Reaction at 25°C for 8h. 2L of ice was added, after the ice melted, it was extracted with chloroform and washed with sodium bicarbonate aqueous solution until it became neutral. After removing the solvent and recrystallization, react with 180g of stannous chloride, 200ml of fuming nitric acid, and 400ml of ethanol at room temperature for 5h. Then...
