聚丙烯酰胺交联固体膜的制备与性能研究
|
摘要
水溶性高分子聚丙烯酰胺(PAM)具有优良的物理化学性能,与水溶性酚醛树脂(PF)反应后,可得到一种既具有溶胀能力又不溶于水的交联PAM固体膜。研究了交联剂用量、催化剂、反应温度以及反应时间对交联成膜的影响,通过接触角的测量、红外光谱分析、SEM分析对固体膜进行了表征,并测试了其吸水性、耐磨性、抗冲击、附着力等性能。结果表明,在酸质量分数为2%、聚交比(PAM与PF的质量比)为2∶1、反应温度为50℃、反应时间为120 min条件下,所制备的交联PAM固体膜的性能最佳。
Polyacrylamide( PAM) is a kind of water-soluble polymer with excellent physical and chemical properties.A cross-linked PAM solid film having both swelling ability and water-insoluble property can be obtained when PAM reacts with the water-soluble phenolic resin( PF). The effects of cross-linking agent dosage,catalyst,reaction temperature and reaction time on the film formation are studied.The solid film is characterized by means of determining contact angle,infrared spectrum and SEM. The water absorption ability,wear resistance,impact resistance and adhesion properties of the PAM solid film are also tested. Results show that the cross-linked PAM solid film has a better performance when it is prepared under the optimum conditions that acid concentration is 0. 2 wt%,the mass ratio of PAM and PF is 2 ∶1,the reaction temperature is set at 50℃ and the reaction time lasts for 120 min.
