Abstract
The invention relates to a preparation method of a waterborne polyurethane synthetic leather base. A waterborne polyurethane resin takes water as a dispersing medium, is nontoxic, environmentally-friendly, safe and inflammable and is an optimal substitute product for a solvent resin. However, the application of the waterborne polyurethane resin to synthetic leather is relatively hysteretic, and is mainly concentrated on surface finishing of the synthetic leather. The preparation method of the waterborne polyurethane synthetic leather base comprises the following steps of: designing a base fabric; pretreating; drying; soaking in waterborne polyurethane slurry; coating a waterborne polyurethane foamed coating; and drying. The product has the basic structure of a solvent type wet process synthetic leather base and has handfeel and physical properties close to those of the solvent type synthetic leather base; solvents are not used for processing in the entire production process; the preparation method can be applied to post-processing manufacturing of any synthetic leather product; and a waterborne polyurethane material is used for post-processing, so that the synthetic leather base can be used for manufacturing shoe leather, sofa leather, case leather, clothes leather and the like.
