IC engine cleaner filter paper and method for making same

Abstract

The invention belongs to the filter technical field, disclosing filter paper used for a filter of an internal combustion engine and a method for making the same. The technical proposal is as follows: the base paper of filter paper is horizontally arranged, and the resin solution is sprayed on the surface of the base paper and penetrates the base paper and is hanged on fiber walls of the base paper of filter paper, and the base paper undergoes drying solidification process to form a resin adhesive layer with supporting action on the surface of the base paper or a certain depth of the base paper, thereby improving the stiffness of the filter paper. The filter paper used for the filter of the internal combustion engine made by the method possesses a certain mechanical strength, anti tearing strength and stiffness and meets requirements of the filter in folding of the filter paper; the hole diameter of a micro hole formed in the invention forms a certain gradient along the radial direction; moreover, the method also achieves an aim of the layered filtration and improves the filtering efficiency; the filter paper for the filter of the internal combustion engine also has the characteristics of big ash storage quantity 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...
