Machine oil filter paper manufacturing process

Abstract

The invention relates to the technical field of filter paper production, and discloses an engine oil filter paper manufacturing process which comprises the following steps: firstly, melt-blowing is performed through a melt-blowing mechanism to obtain a non-woven fabric layer; when the non-woven fabric layer is not completely solidified and shaped, water absorption beads and magnetic powder are sprayed to the non-woven fabric layer through a spraying mechanism; then the non-woven fabric is cooled and shaped through the cooling mechanism; through holes are formed in the cooled and shaped non-woven fabric through a hole forming mechanism to obtain a non-woven fabric center layer; and finally, the two sides of the non-woven fabric center layer are covered with filter paper, one side of the filter paper is coated with protection resin, and the engine oil filter paper is obtained. The non-woven fabric layer is melt-blown through the melt-blowing mechanism and processed to obtain the non-woven fabric center layer, so that the overall structural strength and hydrolysis resistance of the engine oil filter paper are improved; and water absorption beads and magnetic powder are sprayed through the bead spraying device and the powder spraying device when the non-woven fabric is not completely cooled and shaped, so that the sprayed water absorption beads and magnetic powder can be well bonded and embedded with the non-woven fabric and are not easy to separate.

Description

technical field [0001] The invention relates to the technical field of filter paper production, in particular to a process for producing engine oil filter paper. Background technique [0002] Oil filter paper is a key component of the oil filter, which determines the performance of the oil filter. The oil filter paper usually includes a paper filter layer made of ordinary wood pulp as the main component. This kind of paper filter paper itself is very prone to deliquescence due to absorption, has low structural strength, is prone to damage, and has poor durability. Moreover, when the mechanical parts work for a long time, more ferromagnetic impurities are easy to accumulate in the oil, and these ferromagnetic impurities are more harmful to mechanical parts such as the engine. The existing oil filter paper is difficult to filter the ferromagnetic impurities in the oil. demand. Contents of the invention [0003] The object of the present invention is to provide a process fo...
