2) washing and drying the shellfish semi-finished product prepared in the step 1), and ironing and polishing to obtain a wet shellfish;

3) coating surface layer slurry prepared from dry resin on release paper, drying, and coating bonding layer slurry prepared from dry resin on the surface layer to obtain a dry laminated surface layer;

4) attaching the dry-process laminated surface layer prepared in the step 3) to the wet-process bass prepared in the step 2);

5) grinding the sawdust of the oak barks, then pasting the sawdust on the dry-method pasting surface layer in the step 4), drying and then stripping release paper to obtain a semi-finished product of the synthetic leather;

6) carrying out reverse roll printing and graining treatment on the synthetic leather semi-finished product prepared in the step 5) in sequence, and finally adhering a color treatment layer to prepare a hydrolysis-resistant regenerated resin synthetic leather product;

7) and (3) inspecting and testing physical properties of the finished product obtained in the step 6) according to inspection standards, and filling the finished product into a packaging box after the finished product is qualified.

The invention adopts the structure to obtain the following beneficial effects: the hydrolysis-resistant regenerated resin synthetic leather and the manufacturing method thereof provided by the invention have the advantages that the operation is simple, the mechanism is compact, the design is reasonable, the product is more comfortable and breathable, the wear and the folding resistance are realized, the environment is more environment-friendly through the arrangement of the rubber bark regenerated synthetic leather, and the color of the synthetic leather is more uniform and bright through the arrangement of the color treatment layer.
