Abstract

The invention discloses a safe and environmentally-friendly large-porosity oil filter composite filter paper. The safe and environmentally-friendly large-porosity oil filter composite filter paper is characterized in that the safe and environmentally-friendly large-porosity oil filter composite filter paper is prepared by using the following raw materials, by weight, 34-39 parts of a waste cotton pulp, 55-58 parts of a softwood pulp, 3-4 parts of attapulgite, 1-2 parts of cerium oxide, 3-4 parts of silica, 2-3 parts of an anthracite filter, 0.5-0.9 parts of a silane coupling agent kh560, 0.6-0.8 parts of poly(diallyldimethylammonium chloride), 5-7 parts of a polyvinyl acetate emulsion, 3-5 parts of styrene, 0.3-0.5 parts of lauric acid and 1-2 parts of an assistant. In the invention, ceramic raw material powder is crushed, and can be well fused with a paper pulp, so the firmness of the powder in paper is increased, and the porosity of the filter paper is increased; the added assistant is safe and environmentally-friendly, and has good water and oil resistances; and a dipping liquid used in the invention has very strong caking property and film forming ability, and dipping can enhance the dry and wet strength and the toughness of the filter paper, and the filter filtering efficiency is improved.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to a composite filter paper for oil filters with high porosity, safety and environmental protection 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...
