Application of polymerizable emulsifier on preparation of pigment printing binder

A pigment printing binder was prepared with polymerizable emulsifier.The influences of emulsifier and the mass fraction on the monomer conversion rate,polymerization coagulation rate,dissolve-loss rate and mechanical properties of latex film,and color fastness of the pigment printing binder were studied.It was found that compounding the polymerizable emulsifier with traditional emulsifier can improve the polymerization stability.The bonding of polymerizable emulsifier to the latex particle surface can reduce the dissolve-loss rate of latex film,and improve the mechanical properties of latex film and color fastness of the pigment printed fabric.Especially when the mass fraction of polymerizable compound emulsifier was 6%,the emulsion polymerization exhibited higher monomer conversion rate and lower polymerization coagulation rate,the latex film presented lower dissolve-loss rate and higher fracture work,and the pigment printed fabric had excellent color fastness.It is considered that polymerizable compound emulsifier is an ideal option for preparation of non-APEO emulsifier for pigment printing binder.
