Water-resistant and oil-resistant filter paper for oil filter and preparation method thereof

Abstract

The invention discloses a water and oil resistant oil filter paper, which is characterized by being prepared from the following raw materials by weight part: 50-56 of bagasse pulp, 46-49 of Manila hemp pulp, 2-4 of zircon powder, 2-3 of feldspar powder, 1-2 of magnet powder, 0.5-0.9 of n-dodecyltrimethoxysilane, 0.5-0.7 of sodium alginate, 0.2-0.3 of polygalactose mannose, 6-8 of a polyvinyl acetate emulsion, 2-3 of butyl acrylate, 0.5-0.7 of benzalkonium bromide, 0.4-0.6 of polyvinyl ether, and 1-2 of an assistant. Through organic combination of a ceramic material with filter paper, the filter paper prepared by the invention is solid and durable, and has good filtration effect and adsorption effect. Added with the assistant, the oil filter paper is safe and environment friendly, and has good water resistance and oil resistance. The added zircon powder and magnet powder can well filter out the metal abrasive dust generated by an engine in the combustion process and mixed into engine oil, carbon granules, colloid generated by the engine oil, and other impurities, thus reducing exhaust gas emission.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to a water-resistant and oil-resistant oil filter filter paper and a preparation method thereof. Background technique [0002] The oil filter is a type of filter that can remove impurities such as dust, metal particles, carbon deposits, and soot particles in the oil to protect the engine. The oil filter paper is a key component of the oil filter, which determines the performance of the oil filter. The oil filter paper usually includes a paper filter layer made of ordinary wood pulp as the main component. Due to the finer fibers of ordinary wood pulp , low ash capacity, short service life, etc., and the oil filter paper made of paper generally has the characteristics of poor water resistance and oil resistance, no high temperature resistance and no environmental protection. When the fuel is soaked for a long time, it is easy to deform, which will affect the filtering effect. Conte...
