The invention discloses PU (Poly Urethane) synthetic leather resistant to a strong polar solvent and strong acid and alkali as well as a preparation method and application of the PU synthetic leather. The PU synthetic leather structurally comprises a base cloth layer, a bonding layer, a surface layer, a first surface treatment layer and a second surface treatment layer which are sequentially stacked. The preparation method comprises the following steps: S1, manufacturing the surface layer; s2, manufacturing a bonding layer; s3, laminating the base cloth; s4, performing curing treatment; s5, stripping is carried out; s6, first surface layer treatment; and S7, second surface layer treatment. The strength, the heat resistance, the weather resistance and the acid and alkali resistance of the PU synthetic leather are improved by optimizing the structure of the synthetic leather and optimizing the formula and the preparation process of the surface layer and the surface treatment layer. The composite material is applied to passenger car interiors.

    本发明公开耐强极性溶剂及强酸碱的PU合成革及其制备方法与应用,PU合成革结构包括依次层叠设置的基布层、接着层、表面层、第一表面处理层和第二表面处理层。制备方法包括以下步骤:S1、表面层制作;S2、接着层制作;S3、基布贴合;S4、熟化处理;S5、剥离;S6、表面层处理一;S7、表面层处理二。本发明通过对优化合成革的结构及优化表面层和表面处理层的配方及制备工艺,从而达到提高PU合成革的强度,耐热、耐候性和耐酸碱性。并将其应用到乘用车内饰中。
