Abstract Silicone oil was grafted and modified with allyl polyoxyethylene ether (PEO) and allyl glycidyl ether (AGE) via hydrosilylation reactions to enhance the dispersibility in water of the silicone oil, while proper amount of reactive epoxy groups were introduced in order to prepare aqueous phenolic resin. The structures, as well as the stability and heat resistance of the blends of modified silicone oil and aqueous phenolic resin were characterized by FT-IR, 1H-NMR, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) respectively. In addition, silicone-modified phenolic resin was applied to oil filter paper, of which the micro-morphology, mechanical properties, oil resistance and high temperature resistance were examined. The results show that after being co-grafted with PEO and AGE (3:1 in molar ratio) the silicone has good dispersibility in water, and then, the bland complex of aqueous phenolic resin with 5% (mass fraction) of the co-grafted silicone can forms a three-dimensional network structure with good stability. After being reinforced through impregnation of the above bland complex, the oil filter paper presents greatly enhanced mechanical properties. What is more, the reinforced oil filter paper shows high retention rate of mechanical properties even after soaking in high temperature oil, namely, retention rate of 55%, 63%, and 87% for stiffness, burst strength and tensile strength respectively.
