- Abstract
The fluorine-free oil-resistant agent was prepared through free radical polymerization method, with starch, methyl methacrylate, butyl acrylate and methacrylic acid as raw materials. The chemical structure, particle size, Zeta potential and film-forming properties of the pre‐ pared oil-resistant agent were analyzed. Oil-resistant paper for food packaging was prepared by coating waterborne acrylate oil-resistant agent onto base paper, and its dynamic oil contact angle, oil- and water- resistance, high temperature resistance, freezing resistance and repulping performance were studied. The results showed that the synthesized waterborne acrylate oil-resistant agent had uniform particle size distribution and good stability, with average particle size of 254. 2 nm and Zeta potential of −39. 74 mV. The oil-resistant agent could endow the base paper good oil- and water-resistance. When the coating amount was 7. 5 g/m² , the oil resistance could reach 10. 2 grade, and the Cobb value de‐ creased from 24. 2 g/m² to 1. 9 g/m² compared with the base paper. Furthermore, the oil-resistant paper had good high temperature resistance, freezing resistance, and repulping performance.
