1 the synthesis and application of pigment printing binder

With butyl acrylate, methyl methacrylate, styrene and acrylonitrile as monomer preparation is the TF - 320 the self-crosslinking pigment printing adhesive, suitable synthetic technology parameters as: crosslinking monomer is A monomer 3% ~ 3% of total quality; With monomer quality respectively 3% ~ 4% sodium dodecyl sulfate and AEO9 (mass ratio of 1:3) as the composite emulsifier, 0.5% ~ 0.8% ammonium persulfate as initiator, with 0.1% of the total system quality of sodium dihydrogen phosphate as buffering agent, 0.05% are twelve mercaptan as regulator, the reaction temperature at 80 ℃, adopt the method of continuous drops of monomer and initiator, and time control in 2.0 ~ 3.0 h. Under the condition of the obtained products can give the fabric excellent fastness, color yield, high quantity and soft handle, dry and wet rubbing fastness of printed fabric are reaching or higher than a mainstream product.
