Abstract
本发明提供了一种多重绒感羊巴的表面涂层剂，按重量份数，包括以下组分：树脂50‑100份，发泡粉0.5‑5份，高分子微球1‑30份，有机填料0‑10份，助剂0.1‑10份，溶剂0‑100份。这种多重绒感羊巴的表面涂层剂对人造革及其他基材产品进行处理，可以增加羊巴人造革以及其他基材产品的绒毛感、充实感和表面手感，提升羊巴产品的表面耐刮性。本发明还提供了上述多重绒感羊巴的表面涂层剂的制备方法，该方法制备的表面涂层剂可提供爽滑、耐刮和多重绒毛的效果，后续如增加研磨工序，还可获得真皮的反绒、磨砂的效果。
Description
技术领域
本发明涉及人造革生产的技术领域，尤其是涉及一种多重绒感羊巴的表面涂层剂及其制备方法。
背景技术
人造革是一种外观、手感似皮革并可代替其使用的塑料制品，由于具有强度高、加工容易和成本低廉的特点，人造革作为真皮的替代品的得到了广泛应用。
但人造革与真皮还是存在较大差别，其中的一个主要区别点在于，真皮背面是纤维状的绒毛，而人造革的背面是基布。由于植绒产品和羊巴革产品在其中的一面上也具有绒毛，因此在人造革产品中，植绒产品和羊巴革产品是最接近真皮的产品。
为了让人造革的表面产生绒毛，可以采用静电植绒法或者表面处理法。静电植绒法采用专门的静电植绒机在人造革“植入”绒毛粉；表面处理法对人造革的表面或背面处理，经高温发泡后产生类似绒毛的小颗粒。由于静电植绒法需要上胶水和使用绒毛粉，且针对不同绒毛要用不同胶水，配比较为复杂，而且产品风格效果单一，无法调整软硬和不同手感；表面处理法中，由于一些羊巴处理剂的局限性，使得绒毛感不强，绒毛层次和表面手感不足。
为此，如何提供对人造革表面进行羊巴处理的涂层剂，使其表面耐刮，具有良好的手感，是本领域的技术人员需要解决的技术问题。
发明内容
为了解决现有技术存在的上述问题，本发明提供了一种多重绒感羊巴的表面涂层剂及其制备方法，使用该表面涂层剂对人造革及其他基材产品进行处理，可以增加羊巴人造革以及其他基材产品的绒毛感、充实感和表面手感，提升羊巴产品的表面耐刮性。
为实现上述目的，本发明提供了如下技术方案：
一种多重绒感羊巴的表面涂层剂，其特征在于，按重量份数，包括以下组分：树脂50-100份，发泡粉0.5-5份，高分子微球1-30份，有机填料0-10份，助剂0.1-10份，溶剂0-100份。
本申请的表面涂层剂，含有发泡粉和高分子微球，将其涂布在人造革物料表面，经过高温发泡得到发泡颗粒，与高分子微球的颗粒共同形成多重绒毛仿植绒效果的表面层。
作为一种优选的技术方案，所述树脂，按重量份数，包括以下组分：溶剂30-80份，聚碳酸酯PCD多元醇5-30份，聚已内酯多元醇0-30份，聚有机硅多元醇2-20份，二元醇1-20份，二异氰酸酯5-30份，羧基二元醇0-20份，三乙胺0-15份。
所使用的树脂为可成膜树脂，可用溶剂型或水性型PU树脂，也可用无溶剂型的增塑PVC树脂。
作为一种优选的技术方案，所述发泡粉又称羊巴粉，本发明采用的是阿克苏诺贝尔羊巴粉，型号为中小微球920DU40，可膨胀发泡为中小泡的微球，或低温细微球461DU40，可发泡为低温细的微球。
作为一种优选的技术方案，所述高分子微球为聚氨酯微球或聚丙烯酸酯微球的至少一种。
高分子微球使用的聚氨酯微球或聚丙烯酸酯微球可提供耐刮性和耐水解性能，除了带来绒毛效果，本身光滑球状表面更提供爽滑手感和耐刮性能。
聚碳酸酯型聚氨酯还具有耐高温性，有机硅改性聚氨酯树脂带来长久的滑爽手感。
作为一种优选的技术方案，所述有机填料为PP或PE微粉。
作为一种优选的技术方案，所述助剂包括发泡稳定剂、流平剂或增稠剂的至少一种。
作为一种优选的技术方案，所述溶剂为DMF、EAC、BAC或水。
本发明还提供了上述多重绒感羊巴的表面涂层剂的制备方法，包括以下步骤：
(1)合成树脂：按重量份数，取所述溶剂、聚碳酸酯PCD多元醇、聚已内酯多元醇、聚有机硅多元醇、二元醇、二异氰酸酯、羧基二元醇和三乙胺，合成树脂，并调整至合适粘度；
(2)研磨填料：按重量份数，取树脂、溶剂和高分子微球，以砂磨机研磨至细度20μm以下，以200目筛网过滤，得研磨料；
(3)调制：按重量份数，取研磨料、溶剂、发泡剂、有机填料和助剂，搅拌均匀，以200目筛网过滤，即得。
将制备的到的表面涂层剂，涂布于基材的表面，经加温烘干和发泡，得到仿植绒效果的小颗粒。涂布方式可采用刮刀刀涂、印刷轮轮涂和喷涂的方式，基材可选用人造革、纸张、织物和塑料片材等。
发泡工艺科采用烘干发泡分段或连续发泡，后加工工艺有发泡后研磨，改色印刷和后表面处理以改善手感等。
基于上述的技术方案，本发明取得的技术效果为：

(2)本发明提供的表面涂层剂，对人造革及其他基材产品进行处理时，可以单独发泡，组分含有的高分子微球和含有机硅成分的树脂，可提供爽滑、耐刮和多重绒毛的效果；也可以发泡后增加研磨，获得真皮的反绒、磨砂的效果。
(3)本发明提供的表面涂层剂，不受胶水制约，可开发不同软硬、不同表面手感的植绒效果，在处理工序中，仅需加温，烘干和发泡同时进行，适合连续生产工艺。
