The invention relates to the technical field of the papermaking industry, in particular to an environment-friendly curing-free oil filter material and a preparation method thereof. The environment-friendly curing-free oil filter material is obtained by sizing, drying, and double-sided steam humidification on the surface of the base paper, and the sizing agent used for sizing is composed of 5-15 parts epoxy resin, 15-26 parts thermosetting phenolic resin, 45 -52 parts of thermoplastic phenolic resin, 2-5 parts of hexamethylenetetramine, 2-3 parts of dicyandiamide and 65-95 parts of methanol. In the present invention, thermoplastic phenolic resin, thermosetting phenolic resin and epoxy resin are used as sizing agent, and the sizing filter paper is humidified with water vapor on both sides, so that the obtained filter paper has high curing degree and excellent mechanical properties. |
