The invention relates to the technical field of filter paper production, and discloses a process for producing oil filter paper. First, a non-woven layer is obtained by melt-blown through a melt-blown mechanism; Water absorbing beads and magnetic powder are sprinkled on top; then the non-woven fabric is cooled and shaped by the cooling mechanism; through holes are opened on the non-woven fabric that has been cooled and shaped through the opening mechanism to obtain a non-woven central layer; Both sides of the center layer are covered with filter paper, and a protective resin is coated on one side of the filter paper to obtain oil filter paper; in the present invention, the non-woven fabric layer is melt-blown by a melt-blown mechanism and processed to obtain a non-woven center layer, thereby improving the overall oil filter paper. The structure strength and hydrolysis resistance ability; through the bead dispenser and the powder dispenser, the water-absorbing beads and the magnetic powder are sprayed respectively before the non-woven fabric has been completely cooled and shaped, so that the sprayed water-absorbing beads and magnetic powder can be very Good adhesion and fitting with non-woven fabrics, not easy to separate. |
