摘要:

通过测试接触角和表面张力优选了表面活性剂和助溶剂,测试墨水附着性优选了附着力促进剂。配制由色浆、丙烯酸树脂、表面活性剂、附着力促进剂等助剂组成的水性墨水,用红外光谱和热重分析对树脂和树脂-附着力促进剂进行表征,测试墨水经高温和低温存放前后的黏度、微观、pH、粒径D50、表面张力等性能变化,最后测试了优选墨水的书写效果。结果表明,表面活性剂OP-10在该墨水体系中降低表面张力的效果最明显,乙醇润湿性最好;附着力促进剂的效果与其分子结构和添加量有关,过量的附着力促进剂易导致墨水稳定性下降,主要体现在微观、黏度、粒径的变化;优选墨水书写效果良好。

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
