Synthesis and properties of azo-polyethylene ether nonionic foam stabilizer
摘要
Abstract
The nonionic surfactant azo-polyethylene ether (PIP-1000) was synthesized by 4-phenylazophenol,isophorone diisocyanate (IPDI) and polyethylene glycol (PEG Mn=1000). The chemical structure of product was characterized by FTIR, and the surface properties of PIP-1000 was analyzed. The results showed that the critical micelle concentration of PIP-1000 was 0.40 mmol/L, γcmc was 43.2 mN/m, HLB value was 14.12, saturation adsorption capacity was 3.0×10-6 mol/m2, molecular cross section was 0.55 nm2, and the maximum foam ratio was 1.1, which indicated that PIP-1000 presented excellent surface activity. The synergistic effect of PIP-1000 and fatty alcohol polyoxyethylene ether (C12EO7) system was studied. By adjusting the dosage of PIP-1000, the effect of low concentration and high stability foam could be achieved, and compared with single C12EO7 solution, the half foam life period was increased by 75％. Because of its high surface activity, the nonionic surfactant of azo-polyethylene ether could improve the surfactant molecular density and could be used as foam stabilizer for foam dyeing and finishing.关键词
