Description
技术领域
本发明属于聚氨酯乳液技术领域,具体涉及一种超纤革含浸用水性聚氨酯乳液的制备方法和应用。
背景技术
超纤革(全称超细纤维合成革)是以超细纤维制成的具有三维网状结构的基布作为基材,在其内部制备形成聚氨酯弹性体网状结构、尼龙束状结构以及模拟真皮胶原的微观结构,使超纤革具备与真皮类似的弹性、柔软度及丰满手感,也具备优良的力学性能。超纤革作为第3代人工革制品发展至今,其许多方面的性能已经达到甚至超越了天然皮革本身,且超纤革的外表特征也逐渐向天然皮革靠拢。近几年,超纤革因为其生产过程中能够妥善利用非自然资源、价格便宜、生产效率高等优点,已逐步扩大自己的市场规模。
在超纤革生产过程中,含浸步骤十分重要。含浸工艺是以压轧方式将聚氨酯(PU)乳液浸渍到超细纤维基布的间隙中,利用PU的粘连结构,获得与天然皮革相似的质感,含浸的工艺条件及所用的聚氨酯性能决定着超纤革的风格、手感、弹性和力学性能。
目前市场上生产的聚氨酯含浸超纤革主要都是有溶剂型聚氨酯含浸的产品,这是因为溶剂型聚氨酯的各方面性能优良且有成熟的湿法含浸工艺,因此制备得到的超纤革产品性能优秀,手感独特。但是溶剂型聚氨酯在使用过程中因为有机溶剂的残留和挥发造成了严重的环境污染和资源浪费,而且在相关政策的出台颁布下,有机溶剂的回收利用造成生产成本提高,所以溶剂型聚氨酯的使用越来越不方便,市场亟需可以替代溶剂型聚氨酯的无溶剂排放、环境友好的水性聚氨酯进入生产环节,这就需要改善水性聚氨酯力学性能、手感等方面的缺陷。

乳液粒径:取0.5ml水性聚氨酯乳液稀释100倍后,用粒径分析仪测试乳液粒径大小和粒径分布情况。乳液粒径分布图像,如图3所示,可以发现PCDL分子量的增加使得水性聚氨酯相对分子质量越大,聚氨酯长链在水中乳化分散的难度越高,使得乳液粒径增大;此外,软链段PCDL的增长也会使水性聚氨酯分子链的柔顺性增大,链段自身在乳化分散过程中会发生缠绕,导致分散后粒径偏大。随着TMP的含量逐渐增加,水性聚氨酯的乳液粒径先随之减小但粒径分布会随之变广,加入TMP后,水性聚氨酯长链会形成网状交联结构,在乳化分散时团聚形成的乳粒变小。
储能模量与温度曲线:采用动态热机械分析仪分析水性聚氨酯膜的弹性模量。根据仪器测定的尺寸要求,裁取表面干净、厚度均匀、无气泡的WPU膜部位,固定于仪器中,在N2环境中,以5℃/min的升温速率从-90℃升温至90℃,作用频率0.5Hz进行测试。储能模量与温度曲线如图4所示,可以发实施例5高温储能模量更高,回弹能力更加优秀,更适用于水性聚氨酯含浸超纤革的生产流程,对比例1-3的弹性远低于实施例5。
超纤革的截面电镜图:将水性聚氨酯含浸超纤革进行裁剪,用扫描电子显微镜对样品的截面形貌进行观察,扫描电压为5kV。超纤革的截面电镜图如图5所示,可以发现实施例5含浸制备的超纤革由于TMP的加入使得其结构更加紧实,且水性聚氨酯在其内部大多呈膜装固化存在,而对比例1-3的水性聚氨酯制备的超纤革结构松散,且水性聚氨酯在其内部多以拉丝状形态分布。
虽然本发明已以较佳实施例公开如上,但其并非用以限定本发明,任何熟悉此技术的人,在不脱离本发明的精神和范围内,都可做各种的改动与修饰,因此本发明的保护范围应该以权利要求书所界定的为准。
