Abstract

The invention provides a filtering material and a preparation method thereof. The preparation method comprises the following steps: (1), cracking: putting plant fiber as a raw material into a plant fiber cracking treatment system, and cracking to obtain coarse fiber, medium fiber and fine fiber; (2), mixing: proportionally adding the coarse fiber, the medium fiber and the fine fiber into a mixer,and stirring to obtain mixed fiber; (3), soaking: adding a low-zinc additive into the mixed fiber, and soaking; (4), performing spin drying: putting the soaked mixed fiber into a spin drying machine,and deoiling by performing spin drying to obtain the finished filtering material. Through the use of the plant fiber as the filtering material, the filtering effect can be improved; physical and chemical indexes of online lubricating oil are stabilized for a long time by the low-zinc value additive, so that the service life of the online lubricating oil is effectively prolonged; in addition, the plant fiber is wide in source, so that the cost of the filtering material is reduced; furthermore, the used filtering material is convenient to dispose (can be incinerated), so that the filtering material does not cause pollution to the environment and is good in environment friendliness.

Description

technical field [0001] The invention relates to the technical field of filter material production, in particular to a filter material and a preparation method thereof. Background technique [0002] The oil filter is located in the engine lubrication system, its upstream is the oil pump, and its downstream is the parts that need to be lubricated in the engine. Its function is to filter out harmful impurities in the engine oil from the oil pan, and supply the clean engine oil to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other kinematic pairs to lubricate, cool and clean, thereby Extend the life of these components. [0003] At present, in the existing oil filter, the filter element is generally a paper filter element, that is, the filter material is filter paper. The paper filter element is made of microporous filter paper treated with phenolic resin. This filter paper has high strength, good corrosion resistance and moisture resistance, which m...
