Embodiment Construction
[0018] The structure of a filter paper for an internal combustion engine filter provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 Shown is a structural schematic diagram of a filter paper for an internal combustion engine filter provided by the present invention. That is, the basic structure of the filter paper for the internal combustion engine filter, its structure includes a filter paper base paper 1 made of natural fibers or synthetic fibers (such as polyester fibers), the surface and inside of the filter paper base paper are covered with micropores formed by fibers 3 structure, the filter paper base paper is set horizontally, and the phenolic resin or acrylic resin or polyvinyl acetate or other resin glue is sprayed on its upper surface 2 through the spraying process, and the phenolic resin or acrylic resin or polyvinyl acetate will pass through it. The action of gravity pe...

The invention belongs to the technical field of filters, and discloses a filter paper for an internal combustion engine filter and a preparation method thereof. The technical plan is: set the filter paper base paper horizontally, spray the resin glue on the surface, infiltrate its interior and hang it on the fiber wall of the filter paper base paper, and after drying and curing process, the surface of the base paper and a certain depth layer form a support The effect of the resin glue layer, the stiffness of the filter paper is improved. The filter paper for the internal combustion engine filter prepared above not only has certain mechanical strength, tear resistance and stiffness, but also meets the requirements of the filter for pleating the filter paper; Gradient, and achieve the purpose of layered filtering, improve its filtering efficiency. The filter paper for the internal combustion engine filter also has the characteristics of large ash storage capacity and long service life.
Description
technical field [0001] The invention belongs to the technical field of filters, in particular to a filter paper for an internal combustion engine filter and a preparation method thereof. Background technique [0002] Filter paper for internal combustion engine filter is to use microporous filter paper media to filter fuel, engine oil or air entering the engine, and to pass the suspended particles and impurities in the above-mentioned filtered media through the surface and deep layer of the filter paper. It is separated by filtration and stored in it, so as to achieve the purpose of "filtration"; therefore, the filter paper for internal combustion engine filter must have a certain ventilation performance, mechanical strength and the ability to intercept particulate matter. The currently used filter paper for internal combustion engine filter is to soak, extrude and bake the filter paper base paper formed by natural fiber or synthetic fiber (such as polyester fiber) in phenoli...
