Abstract:

Surfactants and co-solvents were optimized by testing contact angle and surface tension, and adhesion promoters were selected by testing ink adhesion. The aqueous ink composed of additives such as pigment paste, acrylic resin, surfactant, and adhesion promoter. The resin and the resin-adhesion promoter were characterized by Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TG). The changes of viscosity, microscopic property, pH, particle size of D50, surface tension and other properties of the ink before and after storage at high and low temperatures were tested. Finally, the writing effect of the optimized ink was tested. The results show that the surfactant OP-10 has the most obvious effect on reducing the surface tension in the ink system, and ethanol has the best wettability. The effect of the adhesion promoter is related to its molecular structure and addition amount. However, excessive adhesion promoters could easily lead to the decline of ink stability, which is mainly manifested in the changes of microscopic property, viscosity and particle size. Here we develop a waterborne marker ink which is stable and has excellent adhesion and good writing effect after optimizing the formula.

Key words: surfactant, waterborne marker ink, acrylic resin, adhesion promoter, stability
