摘要：

The unique advantages of nanoparticles and polymer stabilized foam make it a research hotspot to solve foam stability. In this paper, the effects of hydrophilic silica nanoparticles (NPs) and polymer xanthan gum (XG) on foaming properties, foam stability and spread ability of fluorine-free foam dispersion were explored. The results showed that NPs and XG significantly affected the stability of foam. Compared with NPs, the addition of XG helped to enhance foam stability, but inhibited the foaming performance of foam dispersion. When the mass fraction of NPS was 3.0%, the foaming ability of foam dispersion was improved. When NPs and XG were used together, the additive concentration was controlled, and there was a synergistic effect on the stability of foam. During the spreading process, the viscosity of foam dispersion increased after added NPs and XG that made the spreading speed of foam dispersion on the heptane surface slow down to varying degrees, but it had adversely effect on fire fighting. © 2023 Chemical Industry Press.
