步骤四，内耐用层制造：以重量份计，首先将聚氨酯树脂50-80份进行加热，待聚氨酯树脂变为液态后，在硅油膜上涂刷均匀，涂刷厚度为30-50微米，然后放上一层孔径为0.8-1.2厘米的铜丝网，冷却30-40分钟后，在铜丝网表面再涂刷一层聚氨酯树脂层，涂刷厚度为40-70微米；
步骤五，贴合加热：将步骤三制得的外耐用层与步骤四制得的内耐用层贴合在经过步骤一处理的合成革的表面，然后在设定压力与设定温度下加热设定时间即可完成定型；
步骤六，修整：撕下内耐用层与外耐用层上的硅油膜，然后对步骤五制成的合成革的边缘进行裁剪，去除毛边。
优选的，所述步骤五中设定压力为10-15千克。
优选的，所述步骤五中设定温度为60-75摄氏度。
优选的，所述步骤五中加热设定时间为5-15分钟。
本发明的技术效果和优点：本发明对合成革进行加热以及打磨，从而使得合成革由于热胀冷缩的原理变得较为蓬松，以便于增强外耐用层与内耐用层附着力度，有效避免外耐用层与内耐用层发生脱落的情况，通过利用外耐用层与内耐用层对合成革进行强化，有效增加合成革外部耐磨性能的同时也增加了合成革的强度，从而在不大幅度改变合成革厚度的情况下使得合成革更为耐用。
