Patent number: 12291622Abstract: The disclosure provides a new method for preparing a WPU synthetic leather foaming layer based on a Pickering foam template method. The key of the method is to use the soft waterborne polyurethane as raw materials, add waterborne crosslinking agent and hydrophobic inorganic solid particles as Pickering waterborne foam stabilizers to obtain Pickering waterborne foam slurry of polyurethane latex particles through high-speed emulsification; and dry the slurry to obtain the waterborne polyurethane foam layer. The preparation process does not use any organic solvents, is clean and environmentally-friendly, and is simple to operate, making it easier to realize industrialized production. In addition, the Pickering foam has strong interface stability, which effectively solves the problem of difficult adjustment of the pore size caused by the accumulation and collapse of bubbles during the drying process of the mechanical foaming method, and the prepared synthetic leather foam layer has good hygienic properties.Type: GrantFiled: October 6, 2021Date of Patent: May 6, 2025Assignee: Sichuan UniversityInventors: Chunhua Wang, Wei Lin, Ngai To, Yifeng Sheng, Jianhui Wu
