The invention discloses composite and efficient oil-water-separation filter paper for a hydraulic filter. The composite and efficient oil-water-separation filter paper is prepared by, by weight, 50-55 parts of 3-5mm alkali-free superfine glass fiber, 55-60 parts of bleached softwood pulp, an appropriate amount of distilled water, 0.8-1 part of anionic polyacrylamide, an appropriate amount of concentrated sulfuric acid with the concentration being 98wt%, 10-12 parts of nano titanium dioxide, 20-25 parts of ferroferric oxide colloidal solution with the solid content being 30%, an appropriate amount of anhydrous ethanol, 60-65 parts of fluoro-silicon emulsion with the solid content being 40wt%, 1-1.2 parts of alkenyl succinic anhydride, 7-8 parts of sisal fiber, 3-4 parts of waste rubber powder, 0.9-1.1 parts of silane coupling agent kh550, 1.5-2 parts of organic silicon emulsion and 2-3 parts of urea. By the scientific and reasonable component proportion, the composite and efficient oil-water-separation filter paper is good in absorbability, good in hydrophobic and oleophylic performance and capable of efficiently separating oil and water. When the filter paper is applied to the hydraulic filter, hydraulic equipment can be well protected.
