由于采用以上技术方案，本发明与现有技术相比具有如下有益技术效果：
(1)本发明的水性高光光油是以水代替有机溶剂作为分散介质的新型聚氨酯体系，由于水性聚氨酯以水作分散介质，加工过程无需有机溶剂，因此对环境无污染，对操作人员无健康危害，并且水性聚氨酯气味小、不易燃烧，加工过程安全可靠。水性聚氨酯以水为溶剂，无污染、安全可靠、机械性能优良、相容性好、易于改性等优点；
(2)本发明的水性高光光油的各组分相互协调、共同作用，处理后手感独特，用高光、高透，色泽清晰，综合效果佳，同时配出的喷涂稀释溶液有很好的储存稳定性，颜料不容易沉降；
(3)水性聚氨酯体系中基本不残留有毒的异氰酸酯(-NCO)基团，由于水性聚氨酯无有毒有机溶剂，因此产品中无有毒溶剂残留，产品安全、环保，无出口限制；
(4)水性聚氨酯产品的透湿透汽性要远远好于同类的溶剂型聚氨酯产品，因为水性聚氨酯的亲水性强，因此和水的结合能力强，所以其产品 具有很好的透湿透汽性；
(5)水作连续相，使得水性聚氨酯体系粘度与聚氨酯树脂分子量无关，且比固含量相同的溶剂型聚氨酯溶液粘度低，加工方便，易操作；
(6)水性聚氨酯的水性体系可以与其它水性乳液共混或共聚共混或共聚，可降低成本或得到性能更为多样化的聚氨酯乳液，因此能带来风格和性能各异的合成革产品，满足各类消费者的需求；并且，由于近年来溶剂价格高涨和环保部门对有机溶剂使用和废物排放的严格限制，使水性聚氨酯取代溶剂型聚氨酯成为一个重要发展方向；
(7)使用本发明的水性高光光油制成的成品手感丰满，质地柔软，舒适，具有不燃、无毒、无污染等优点。将成革的透氧气性、透湿性、低温耐曲折性、耐干湿擦性、耐老化性等，与溶剂型聚氨酯涂饰后的合成革进行了对比研究。采用水性聚氨酯替代传统的溶剂型聚氨酯完成合成革的后整理，成革的透气性、透湿性、低温耐曲折性、耐干湿擦等性能均优于前者，整个工艺过程没有溶剂排放，环境友好；
(8)该产品还可根据需求进行二次研发，具有良好的市场应用价值；
(9)本发明的合成革用水性高光光油是后段处理的一种新型材料，能够用于现有的合成革生产线，工艺简单，无需改变生产设备，不会增加生产成本。
