摘要
以异佛尔酮二异氰酸酯(IPDI)、聚丙二醇(PPG400)、N,N-二甲基乙醇胺(DMEA)、甲基-1-苯基膦杂环3-戊烯-1-氧化物(MPPO)为原料,合成了水性阳离子聚碳化二亚胺交联剂。主要探讨了合成条件:催化剂用量、聚合时间、聚合温度、氮气喷射速度、亲水封端剂、封端温度及封端剂用量等因素对产物性能的影响。将成品在蛋白类涂饰剂中应用,应用试验表明:加入交联剂的涂饰剂成膜耐水、碱和溶剂性都有所提高,耐曲折性变好,抗张强度增强,光亮度和透明度稍有下降。
Aqueous cationic polycarbodiimide crosslinking-agent was synthesized with isophorone diisocyanate（ IPDI） ,polypropylene glycol（ PPG400） ,N,N-dimethyl ethanolamine（ DMEA ） ,3-methyl-1-phenyl-2-phosopholene-1-oxide（ MPPO） 3 as raw materials. The influences of synthesis conditions such as the dosage of catalysis agent,reaction time,reaction temperature, nitrogen jet velocity,hydrophilic end-blocking agent and temperature on the blocking reaction,the dosage of end-blocking were investigated. The developed crosslinking agents were introduced to protein finishing agent. And it is found that the properties of obtained finishing film agent are better in the water resistance,alkaline resistance,solvent resistance and flexibility resistance. Also,the tensile strength of film increases with a little decrease in brightness and transparency.
