优选地，底料原料为溶剂型聚氨酯浆料或水性聚氨酯浆料。
本发明还提出上述微发泡皮裤材料的制备方法，包括如下步骤：
S1、将面料原料搅拌混合均匀后，涂覆在离型纸表面，干燥制得皮裤面层；
S2、将微发泡料原料混合均匀，经空气发泡机发泡后，涂覆皮裤面层表面，干燥制得皮裤中间微发泡层；
S3、将底料浆料涂敷在皮裤中间微发泡层表面，再与基布半干贴合后，干燥制得微发泡皮裤材料。
优选地，S1中面料的涂覆量为100-200g/m2，干燥温度为120-140℃，干燥时间为2-5min。
优选地，S2中微发泡料的发泡倍数为1.5-2.5倍，涂覆量为200-300g/m2，干燥温度为100-120℃，干燥时间为3-6min。
优选地，S3中底料涂覆量为80-150g/m2，干燥温度为120-140℃，干燥时间为1-3min。
本发明以基布、底料、微发泡料、面料为原料组成微发泡皮裤材料，其中，以水性聚碳酸酯型聚氨酯树脂、水性增稠剂、水性消泡剂、水性滑爽剂、水性流平剂及水为原料制得皮裤面料，高韧、耐磨，手感好；以水性聚醚型聚氨酯树脂、十二烷基硫酸钠、纳米木质素、纳米二氧化硅、聚碳化二胺、羟乙基纤维素、聚氧乙烯聚氧丙烯季戊四醇醚、聚二甲基硅氧烷及水为原料，经空气发泡机发泡制得微发泡料，作为皮裤中间微发泡层，手感柔软、透气性能好；以溶剂型或水性聚氨酯作为皮裤底料，与基布的附着力好；本发明采用离型纸转移工艺，将面层、中间微发泡层、底层分别涂覆到离型纸上，再经半干法工艺贴合基布制得微发泡皮裤材料，避免湿法工艺贴合手感硬的问题，制得皮裤材料的手感柔软、肉感强，透气性能好。
