Embodiment 1
[0051] Polyurethane emulsion formulation:
[0052]
[0053]Textile washing resistance flame retardant synergist formula:
[0054]
[0055] 1. Preparation
[0056] (1) Under the protection of inert gas nitrogen, react 30mol toluene diisocyanate with 10mol trimethylolpropane at 60°C for 1.5h to prepare -NCO group-terminated prepolymer I, and then add 2mol of N-methyl diisocyanate Ethanolamine and 1 mol of polyethylene glycol monomethyl ether 500 were reacted at 60°C for 2 hours to prepare prepolymer II (reacted to the set -NCO group content);
[0057] (2) The prepolymer II and 13mol of tribromoethanol were subjected to a capping reaction at 60°C for 2 hours to obtain the prepolymer III (reacted to the set -NCO group content), and then the prepolymer III was mixed with 12mol of methyl ethyl ketone The oxime was subjected to capping reaction at 60°C for 4h (reaction until the -NCO group content was set to zero), cooled to below 40°C and added 3mol acetic acid for neutraliz...
