20220186429 · 2022-06-16 · ·

A method for preparing a novel waterborne polyurethane foam layer for synthetic leather is disclosed. The method includes first preparing a charged cellulose nanofiber by using a wood pulp as a raw material; meanwhile, subjecting a polyisocyanate, a macromolecular diol, a hydrophilic chain extender and a small molecular chain extender to a polyaddition reaction and an acid-base neutralization reaction in sequence, to obtain a cationic or anionic waterborne polyurethane; adding the charged cellulose nanofiber and a certain amount of a crosslinking agent to the oppositely charged ionic waterborne polyurethane emulsion, stirring the resulting mixture, forming a bimolecular layer at the gas/liquid interface by a self-assembly of the cellulose nanofiber and waterborne polyurethane nanoparticles through electrostatic interactions to obtain a stable Pickering foam; using the stable Pickering foam as a template, drying and solidifying to obtain the waterborne polyurethane foam layer for synthetic leather.

Matted polyamide-pud

Polymers are disclosed that incorporate portions of secondary or tertiary polyamide segments connected with polyisocyanates. These polymers have enhanced matting properties. The enhanced matting properties are from creating an inherently matt surface from the polymer without the use of any separate fine particle size matting additives. Conventional matting agents such as fine particle size silica usually results in loss of physical properties such as haze development and porosity in the coating from the matting agent. Composites and hybrids of these polymers and other polyamides, polyurethane with vinyl polymers (acrylates) are also disclosed and claimed.
