P4、将辅助片原料充分混合形成混合原料，再排入混炼机进行混炼，接着排入炼胶机内进行塑炼，再送入压延机进行压延，形成辅助片；
P5、使用切割机对TPU基材的两侧表面进行切割，形成第一切割槽，对辅助片的一侧表面进行切割，形成第二切割槽。
P6、将胶水加入到涂胶机中进行加热，然后均匀涂布在TPU基层的两侧表面，然后抹平形成粘胶层，保持厚度为0.1毫米至0.15毫米；
P7、将辅助片通过贴合机贴合在粘胶层上，贴合压力为7000Pa至9000Pa，得到人造革坯料；
P8、在人造革坯料的两侧表面涂布耐碱涂料，形成耐碱层，保持厚度为0.1毫米至0.15毫米，然后静置15分钟至20分钟，得到半成品人造革；
P9、对半成品人造革进行修整，去除边沿残留物和线条，得到成品人造革。
优选的，所述P1步骤中的TPU原料颗粒包括聚合物多元醇30%-60%、二苯基甲烷二异氰酸酯20%-30%、硅藻土10%-15%、硅烷催化剂1%-3%、芳烷改性聚硅氧烷耐磨剂5%-8%和硅烷催化剂2%-5%。
