Preparation method of phosphorus-nitrogen-silicon-based flame-retardant pigment dyeing adhesive

Abstract

The preparation method comprises the following steps: preparing waterborne polyurethane by selecting blocked isocyanate, dihydric alcohol, a hydrophilic chain extender, a cross-linking agent and a polyol phosphorus-containing flame-retardant functional component as raw materials, preparing waterborne polyurethane by taking methyl methacrylate and butyl acrylate as polyacrylate monomers, and preparing the flame-retardant pigment dyeing adhesive by adopting a one-step method, the POSS-based polyurethane acrylate core-shell emulsion, which takes waterborne polyurethane acrylate as a shell component and takes octavinyl octasilsesquioxane as a core component, is prepared as the flame-retardant adhesive containing the combination of various elements such as phosphorus, nitrogen and silicon by taking the POSS-based polyurethane acrylate core-shell emulsion as a core component and taking the POSS-based polyurethane acrylate core-shell emulsion as the core component and taking the POSS-based polyurethane acrylate core-shell emulsion as the core component, and meanwhile, adding octavinyl octasilsesquioxane as a cross-linking agent. The pigment dyeing adhesive disclosed by the invention has good adhesive property, and can form a stable transparent film on the surface of a fabric, so that the fabric has relatively strong color fastness and flame-retardant effect.
