Problems solved by technology

[0006] At present, high-end fuel filters are mostly filtered by multi-layer winding filter method. Compared with single-layer pleated filter method, multi-layer winding filter fuel filter paper increases fuel flow and filtration accuracy, but for fuel filter paper The requirements are high, and the filtration efficiency of ordinary fuel filter paper is still limited

Abstract

The invention provides fuel oil filter paper and a method for preparing the fuel oil filter paper. The fuel oil filter paper comprises, by weight percentage, 0-20% of resin, 0-38% of polyester fiber, 42-100% of wood pulp celluloses and 0-1% of wet strength agents, and is corrugated filter paper. Compared with existing fuel oil filter paper, the polyester fiber has high temperature resisting performance and can be well combined with the wood pulp celluloses; blending of the polyester fiber and the wood pulp celluloses can be carried out according to a certain proportion to obtain paper which has good high temperature resisting performance and is of a labyrinth-type structure, the ventilating performance of the fuel oil filter paper is guaranteed, the maximum hole diameter of the filter paper is reduced, and the fuel oil filter paper has higher filtering precision and can effectively remove impurities in oil and improve oil quality and fuel oil utilization ratio. Furthermore, because the fuel oil filter paper has a corrugated structure, filtering gaps can be increased, the effective contact area of the fuel oil and the filter paper can be increased, and filtering precision and filtering efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of filter paper, and in particular relates to a fuel filter paper and a preparation method thereof. Background technique [0002] Automotive filter paper is one of the main materials for the production of automotive filters, also known as the three automotive filter papers, namely air filter paper, oil filter paper, and fuel filter paper. It is a filter paper impregnated with resin. Filters are made by processes such as wave pressing, wave receiving and curing. Automobile filter paper plays the role of "lung" of automobile engine on internal combustion engines such as automobiles, ships, tractors, etc., to remove impurities in air, engine oil and fuel, prevent engine parts from wearing out, and prolong their service life. [0003] Among them, fuel filter paper is used in automobile internal combustion engines, which is an important component of fuel filters and determines the performance of fuel filters. It...
