Problems solved by technology

The common oil filter paper on the market is usually a kind of paper filter layer made of ordinary wood pulp. Poor water resistance, poor strength, and poor temperature resistance; on the other hand, the fiber composition is single, and the relationship between filtration efficiency and dirt-holding capacity cannot be coordinated, and it is difficult to increase its dirt-holding capacity on the premise of ensuring filtration accuracy
In turn, it cannot meet the long-term working requirements of the oil filter

Abstract

The invention provides thermosetting engine oil filter paper which comprises a paper filter layer and a resin layer, and the paper filter layer is coated with the resin layer; the paper filter layer is prepared from the following raw materials in percentage by mass: 10%-30% of coniferous wood fibers, 25%-50% of mercerized pulp fibers, 0%-15% of cotton linter fibers, 20%-40% of PET fibers, 0%-10% of aramid fibers, 0%-5% of glass fibers, 0%-0.1% of a dry strength agent, 0.5%-1.5% of a wet strength agent and 0.1% of a dispersing agent; and the resin layer is thermosetting phenolic resin. The invention further provides a preparation method of the thermosetting engine oil filter paper. The engine oil filter paper disclosed by the invention has the advantages of good strength, temperature resistance and hydrophobicity, small pore size, high air permeability and excellent filtering performance.

Description

technical field [0001] The disclosure relates to the field of filter paper technology, in particular to a thermosetting oil filter paper and a preparation method thereof. Background technique [0002] Engine oil filter paper is a filter paper with high stiffness and strength after the base paper of the filter paper is impregnated with phenolic resin, and can withstand a certain pressure difference after heat curing treatment. It is the key material of the engine filter system. It can filter out dust, metal particles and carbon deposits in the engine oil to ensure the cleanliness of the engine oil, thereby reducing the wear and tear between the mechanical parts of the engine, cleaning the engine and prolonging its service life. With the continuous development of engine technology, the performance requirements of oil filter paper continue to increase, especially as the requirements for oil filter replacement mileage continue to increase, the requirements for the amount of dirt...
