Title: Innovations of Wei Lin in Synthetic Leather Technology

Introduction

Wei Lin is an accomplished inventor based in Chengdu, China. He has made significant contributions to the field of synthetic leather technology, holding 3 patents that showcase his innovative methods. His work emphasizes environmentally friendly processes and the use of advanced materials.

Latest Patents

Wei Lin's latest patents include a method for preparing WPU synthetic leather foaming layers based on the Pickering foam template method. This innovative approach utilizes soft waterborne polyurethane as raw materials, combined with a waterborne crosslinking agent and hydrophobic inorganic solid particles. The resulting Pickering waterborne foam slurry is created through high-speed emulsification, leading to a clean and environmentally friendly preparation process. This method effectively addresses the challenges of pore size adjustment during the drying process, resulting in synthetic leather foam layers with excellent hygienic properties.

Another notable patent is a method for preparing a novel waterborne polyurethane foam layer for synthetic leather. This process begins with the preparation of charged cellulose nanofibers from wood pulp. It involves a series of reactions to create a cationic or anionic waterborne polyurethane, followed by the addition of charged cellulose nanofibers and a crosslinking agent. The self-assembly of these components forms a stable Pickering foam, which is then dried and solidified to produce the final foam layer.
