Effect of nonionomer emulsifier on particle stability of waterborne polyurethane adhesives

Preparation of a flame-retardant waterborne polyurethane with core–shell structure and its application in a fire-resistant microfiber synthetic leather

“…Since WPU is a macromolecular polymer with both hydrophilic and hydrophobic chains, it can spontaneously form stable nano micelles with hydrophilic chains as the “shell” and hydrophobic chains as the “core” in aqueous dispersions. 21,22 Taking advantage of this characteristic of WPU, in this study, HPCTP was wrapped with WPU to prepare stable fireproofing-modified WPU, and its properties were investigated. Then, the modified WPU was compounded with melamine and flame-retardant waterborne polyurethane AO 10 D 3 -WPU (self-made in the lab) to prepare flame-retardant microfiber leather using a two-step method.…”

Synthesis and characterization of flame‐retardant polyurethane based on new chain extenders

“…Waterborne polyurethane (WPU) with excellent dispersion and stability in water through emulsification 1–3 has attracted considerable attention as a promising environmentally friendly polymer 4–6 . Over the past few decades, WPU has been widely used in leather processing, 7, 8 textiles, 9 the paper industry, architectural coatings 10 and adhesives 11–13 . Nevertheless, WPU can be dangerous due to its flammability 14 .…”

“…[4][5][6] Over the past few decades, WPU has been widely used in leather processing, 7,8 textiles, 9 the paper industry, architectural coatings 10 and adhesives. [11][12][13] Nevertheless, WPU can be dangerous due to its flammability. 14 So flame-retardant modification has become one of the most mainstream directions for the functionalization of WPU.…”
