一种水性发泡绒感无溶剂复合型沙发用聚氨酯合成革及其制 备方法
技术领域
本发明涉及一种聚氨酯合成革，具体涉及一种水性发泡绒感无溶剂复合型沙发用聚氨酯合成革及其制备方法。
背景技术
伴随着聚氨酯合成革技术的不断发展，合成革的种类愈加丰富。消费者不仅注重合成革的外观效果，也同时会在意革制品的内在品质。传统的合成革表面会涂覆或者喷涂一层树脂材料，造成革面表面光滑，整体塑胶感强。而绒感磨砂革制品由于其绒面丰富细腻，手感极致舒适，真皮效果好，越来越受到消费者的青睐。
绒感合成革，一般可以通过绒感磨砂离型纸贴面成型法、后处理磨毛成型法、表面发泡成型法等工艺制备。绒感磨砂离型纸贴面法，是利用绒感效果的离型纸，涂覆树脂贴合基材，将材料从离型纸上剥离下以获得绒感效果，此方法的劣势在于树脂材料的模量选择要求高，高模量树脂虽然耐磨，但易造成“速剥离”等贴面疵病；低模量树脂虽然满足贴面性能，但是树脂表面耐磨性能弱、耐用性差。后处理磨毛成型法是利用磨毛机和金刚砂皮的摩擦作用，在合成革半成品表面形成短绒毛层感觉，此方法制备的绒感效果自然，但却无法具备功能性效果，表面极易被污染和磨损。表面发泡成型法是在合成革半成品表面涂覆发泡材料，利用高温条件下微球发泡基材迅速膨胀，达到发泡效果，在表面形成高粗糙度的绒感效果，此方法制备的绒感效果具有多样性，成品的物性对发泡物料依赖性很大。
中国专利CN207619705U公开了一种水性丝光绒感聚氨酯合成革，包括基布层、湿法聚氨酯层、干法涂层和丝光绒层，基布层设置在最底层，湿法聚氨酯层设置在基布层的上表面，干法涂层设置在湿法聚氨酯层的上表面，丝光绒层设置在干法涂层的上表面。此类产品为离型纸法，利用的基材为湿法贝斯，VOC含量高，环保性差。
中国专利CN105839425A公开了一种水性聚氨酯发泡绒感绸感合成革的配方,将涂层液制成涂层泡沫体，涂敷到革基布上，烘干得发泡绒感绸感贝斯，后处理和表面处理得聚氨酯发泡绒感绸感合成革。此涂层液直接涂覆在基布上，容易渗入布基，造成成品手感差，耐水解性能差，且发泡处理后还需要后处理和表面处理，加工工序多，生产效率不足。
综上，制备出一款具备环保型和耐用性共存的发泡绒感合成革，十分必要。
发明内容
