【摘要】：以聚丙烯纖維和聚乙烯/聚丙烯雙組分皮芯結(jié)構(gòu)(ES)纖維為原料,采用濕法成形工藝制備勻度高、質(zhì)量高的堿性電池隔膜。通過調(diào)節(jié)濕法成形和熱壓條件改變隔膜的內(nèi)部結(jié)構(gòu),采用磺化處理方法使隔膜具有吸堿性,探索濕法成形工藝制備聚烯烴堿性電池隔膜的優(yōu)化工藝。結(jié)果表明,隔膜成形的最佳熱壓壓力和熱壓溫度分別為0.5 MPa和135℃,纖維之間形成了多接觸點的熔融結(jié)合,隔膜手抄片強度上升;聚氧化乙烯(PEO)用量為1.5%、聚乙烯醇(PVA)用量為4%和ES纖維用量為40%時,可以獲得勻度和機械強度較好的隔膜;磺化后的隔膜成功接枝上磺酸基,使隔膜具備較強的親水性。自制堿性電池隔膜的性能均符合行業(yè)標準GJB3535(1999)的要求。
[Abstract]:Using polypropylene fiber and polyethylene / polypropylene two-component core-structure ESU fiber as raw materials, alkaline battery diaphragm with high evenness and high quality was prepared by wet forming process. The internal structure of diaphragm was changed by adjusting wet forming and hot pressing conditions. The method of sulfonation was used to make the membrane have absorbent alkalinity. The optimum process of preparing the membrane of polyolefin alkaline battery by wet forming process was explored. The results showed that the optimum hot pressing pressure and temperature of membrane forming were 0.5 MPa and 135 鈩，
