| 摘 要： | 以聚四氢呋喃二醇(PTMG)、异佛尔酮二异氰酸酯(IPDI)、二羟甲基丙酸(DMPA)为预聚物反应单体,2-[(2-氨乙基)氨基]乙磺酸钠(A95)、水合肼为后扩链剂,制备水性聚氨酯消光树脂分散体。利用傅里叶变换红外光谱仪(FTIR)表征其结构,用扫描电子显微镜(SEM)、原子力显微镜(AFM)分析漆膜的表面结构;结果表明,WPU膜表面微观结构符合消光机理,当w(铋酸催化剂)=0.016%、w(水合肼)=45%、w(DMPA)=2.6%、w(A95)=0.084%时制备的聚氨酯膜消光性能最优。

| Abstract: | With isophorone diisocyanate (IPDI) and polytetramethylene glycol (PTMG) as main materials, dihydroxy methyl propionic acid (DMPA) as hydrophilic chain extender, A95 and hydrazine hydrate as small molecule chain extender, a low gloss waterborne polyurethane(WPU) dispersion was prepared by prepolymer dispersing method. The structure and surface of the WPU film were investigated by FTIR,AFM and TEM. Results show that WPU film surface microstructure fit with the extinction mechanism of low gloss. When wBismuth acid catalyst=0.016%,w hydrazine hydrate = 45%, wDMPA = 2.6%, wA95 = 0.84%, the WPU film has a good low gloss performance. |
