Embodiment 1
[0019] A method for preparing plastic particles for antistatic and flame-resistant shoes, specifically comprising the following steps
[0020] (1) After adding 3.1 parts of SEBS and 5.1 parts of maleic anhydride in the reaction kettle, add 16 parts of xylene. After it is completely dissolved, control the temperature with a water bath, protect it under a nitrogen atmosphere, and add dropwise a mass fraction of 0.9% 1.2 parts of toluene solution of BPO, the reaction time is 1~2h, the reaction solution is poured into acetone for precipitation, suction filtration, air drying, and vacuum drying to obtain maleic anhydride grafted SEBS, SEBS is YH-503;
[0021] (2) Add 14 parts of SEBS and 3.9 parts of maleic anhydride grafted SEBS to another reaction kettle, and add 17 parts of solvent xylene. When SEBS and maleic anhydride grafted SEBS are completely dissolved, add a mass fraction of 16 parts of 6.1% acrylamide aqueous solution, stir to form an emulsion, control the temperature wit...
Embodiment 2
[0028] A method for preparing plastic particles for antistatic and flame-resistant shoes, specifically comprising the following steps
[0029] (1) After adding 2.4 parts of SEBS and 3.4 parts of maleic anhydride in the reaction kettle, add 14 parts of xylene, after it is completely dissolved, control the temperature with a water bath, protect it under a nitrogen atmosphere, and add dropwise a mass fraction of 0.5% 1.1 parts of toluene solution of BPO, the reaction time is 1h, the reaction solution is poured into acetone to precipitate, suction filtered, dried in the air, and vacuum-dried to obtain maleic anhydride grafted SEBS, SEBS is YH-502;
[0030](2) Add 14 parts of SEBS and 3.9 parts of maleic anhydride grafted SEBS to another reaction kettle, add 15~17 parts of solvent xylene, when SEBS and maleic anhydride grafted SEBS are completely dissolved, add mass The fraction is 15-16 parts of acrylamide aqueous solution with a fraction of 4.5%, stir to form an emulsion, control...
