Ferromagnetic composite filter paper for oil filter and preparation method of composite filter paper

Abstract

The invention discloses a piece of ferromagnetic composite filter paper for an oil filter. The composite filter paper is characterized by being prepared by raw materials in parts by weight as follows: 55-58 parts of mulberry pulp, 40-45 parts of manila hemp pulp, 2-3 parts of nano-silica, 1-2 parts of magnet powder, 3-4 parts of mullite, 2-3 parts of albite, 0.5-1 part of a titanate coupling agent TC-101, 0.7-0.9 part of poly dimethyl diallyl ammonium chloride, 4-5 parts of alkyl ketene dimmer, 1-2 parts of wheat starch, 2-4 parts of animal glue, 3-5 parts of water-soluble phenol-formaldehyde resin, 0.4-0.6 part of nonyl phenol polyoxyethylene ether and 1-2 parts of an auxiliary. According to the composite filter paper, raw ceramic material powder is crushed, so that the powder can be well mixed with paper pulp, and the firmness of the powder in the paper can be increased; the magnet powder is added, so that metal impurities produced during combustion of an engine can be well filtered out, the auxiliary is added, and the filter paper is safe, environment-friendly, good in water resistance and oil resistance, excellent in combination property and long in service life.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to a composite filter paper for oil filters with strong magnetism 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. Co...
