技术领域
本发明属于合成皮革技术领域，尤其涉及一种高物性玻纤加强的人造革及其制备方法。
背景技术
随着时代的进步发展，对于皮具的需要已经不仅仅局限于真皮。各种仿真产品已经可以替代部分的真皮制品。自人造革产品面试以来，市场上出现了各种纹路、规格的产品，功用也呈多元化发展，对不同场景中应用的合成革也有了不同的要求。而且随着环保要求的提供，对人造革是否有异味产生的要求越来越高，由于人造革面料生产中使用有高分子化合物助剂，所以或多或少都会产生一定的化学品异味逸出，直接使用时有逸出的学品异味。虽然通过时效处理，产品中高分子化合物中逸出的学品异味会逐步减少，直到不在有异味逸出，但这一时间往往较长，而生产供货和使用是不可能等到这个时候。所以在保证人造革一定的物理性能的前提下，使制备过程更环保是研究的重点。

所述玻纤层为玻璃纤维网格布，为玻璃纤维编织而成，厚度为0.5-0.8mm。
一种高物性玻纤加强的人造革的制备方法，包括以下步骤：
步骤1：取质量份组分水性聚氨酯树脂50-80份、抗氧化剂0.5-1份、防霉剂0.3-0.8份，混合均匀得到树脂层浆料；
步骤2：将步骤1得到的树脂层浆料均匀涂覆一定厚度于基布表面；
步骤3：将玻璃纤维编织的玻璃纤维网格布平整贴合于步骤2树脂层表面，烘干；
步骤4：将TPO树脂70-80份、填充料5-15份、抗氧化剂0.5-1份、紫外光吸收剂0.5-1份混合均匀，均匀涂覆一定厚度于步骤3玻璃纤维网格布表面，烘干。
以上所述步骤中，步骤1和步骤4树脂浆料在45-55℃下混合均匀。
有益效果：本发明提供一种高物性玻纤加强的人造革及其制备方法，制备得到的人造革从下至上依次为基布层、PU树脂层、玻纤层、TPO层；PU树脂层采用水性聚氨酯树脂，环保无污染，采用玻璃纤维网格布作为增强层，表层采用TPO树脂层，具有密度小，高弹性，使人造革具有优良的柔软度及低温性能；并使用玻璃纤维作为填充料，进一步增强了人造革的耐高温耐低温性能，并且弹性系数高，刚性佳。
