Below in conjunction with series of experiments example, the present invention is described further:
Experimental example 1 synthesis of polyurethane acrylate performed polymer
The present invention selects polyoxyethylene glycol, tolylene diisocyanate (TDI), hydroxyethyl methylacrylate (HEMA), two lauric acid butyl tin, Resorcinol and butyl acrylate as the synthesis material of synthesis of polyurethane acrylate performed polymer.Wherein, polyoxyethylene glycol provides soft chain segment molecular structure, for the overall performance of polyurethane acrylate prepolymer provides snappiness.TDI provides hard segment molecule structure, for urethane performance contributes, HEMA is performed polymer end-blocking and is the two keys of introducing in molecular chain, adopt two lauric acid butyl tin as product positive catalyst, to biphenol as poly-resist, butyl acrylate is as solvent, hierarchy of control viscosity, and can in formula, solidify.
Synthesizing formula: polyoxyethylene glycol: 24 parts, tolylene diisocyanate (TDI): 12 parts, 29 parts of hydroxyethyl methylacrylates, (HEMA), 35 parts of 0.4 part of two lauric acid butyl tin, Resorcinol 0.4, butyl acrylate,
Synthesizing of polyurethane acrylate prepolymer:
1, purification raw material, because-NCO can with in water-OH reacts, moisture in raw material can consume TDI, molecular structure to the ratio of raw material and performed polymer impacts, therefore must purify to raw material, polyoxyethylene glycol, β-dimethyl-aminoethylmethacrylate, butyl acrylate are placed in respectively to Rotary Evaporators, at a certain temperature, carry out underpressure distillation purification.
