摘　　要：动力电池包冷却液泄露引发电路短路是导致新能源汽车自燃的主要原因,冷却液快速吸收材料是解决这一问题的有效途径。采用自由基聚合法合成了丙烯酸-2-丙烯酰胺-2-甲基丙磺酸共聚物P(AA/AMPS)冷却液吸收树脂,通过控制变量法确定了合成树脂的最佳工艺条件,并系统研究了单体配比、丙烯酸(AA)中和度和交联剂N,N′-亚甲基双丙烯酰胺(MBA)用量对树脂吸收冷却液性能的影响规律。结果表明:当单体AA与2-丙烯酰胺-2-甲基丙磺酸(AMPS)的比例为4∶1,AA中和度为80%,交联剂MBA用量为0.10%时,P(AA/AMPS)树脂对冷却液的吸收倍率最高,达到120g/g。Power battery pack coolant leakage triggering circuit short circuit is the main cause of spontaneous combustion in new energy vehicles,and coolant rapid absorption material is an effective way to solve this problem.In this paper,an acrylic acid-2-acrylamide-2-methylpropanesulfonic acid copolymer P(AA/AMPS)coolant absorbing resin was synthesized by free radical polymerization.The optimal process conditions for the synthesis of the resin were determined by the controlling variables method,and the influences of the ratio of the monomer ratio,the degree of neutralization of the acrylic acid(AA),and the dosage of the cross-linking agent N,N′-methylenebisacrylamide(MBA)on the performance of the resin in absorbing the coolant were systematically investigated.The results showed that when the ratio of monomer acrylic acid(AA)to 2-acrylamido-2-methylpropanesulfonic acid(AMPS)was 4∶1,the neutralization degree of AA was 80%,and when the dosage of cross-linking agent(MBA)was 0.10%,the highest coolant absorption multiplicity was achieved by P(AA/AMPS)resin,which reached 120g/g.
