Water-resistant and oil-resistant oil filter filter paper added with nano-titanium dioxide and preparation method thereof

Abstract

The invention discloses a water and oil resistant oil filter paper added with nano-titanium dioxide. The oil filter paper is characterized by being prepared from the following raw materials by weight part: 36-41 of poplar bark pulp, 60-63 of waste hemp rope pulp, 2-3 of nano-titanium dioxide, 2-3 of heavy calcium carbonate, 2-4 of zeolite, 1-2 of magnet powder, 1-2 of chopped glass fiber, 0.5-1 of a silane coupling agent WD-10, 0.3-0.5 of sesbania gum, 0.4-0.5 of guar gum, 5-7 of polyamide epichlorohydrin resin, 2-4 of carboxymethyl cellulose, 0.3-0.5 of octanol, 0.2-0.4 of castor oil, and 1-2 of an assistant. According to the invention, the added nano-titanium dioxide and the like can enhance the adsorption effect, the magnet powder can adsorb metal impurities blended into engine oil during engine combustion; by adding the assistant, the oil filter paper is safe and environment-friendly, and has good water resistance and oil resistance; and through organic combination of a ceramic material and a filter paper, the water and oil resistant oil filter paper is solid and durable, and has good filtration adsorption effect.

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 added with nano-titanium dioxide 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 aff...

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, high temperature resistance and environmental protection. When the fuel is soaked for a long time, it is easy to deform, which will affect the filtering effect.
