Abstract

The invention relates to the technical field of filter materials, and discloses diesel oil filter paper which comprises filter paper body paper and impregnation liquid used for impregnating the filter paper body paper. The filter paper body paper comprises the following components in parts by weight: 50-70 parts of hardwood pulp, 15-20 parts of straw pulp, 15-25 parts of miscanthus pulp, 10-15 parts of carboxymethyl fibers, 20-30 parts of silicon dioxide short fibers, 1-1.5 parts of silica gel powder and 0.5-1 part of zinc borate; the impregnation liquid is prepared from the following components in parts by weight: 40 to 50 parts of ethyl silicate, 5 to 10 parts of potassium permanganate, 30 to 40 parts of stearic acid modified liquid and 80 to 120 parts of industrial methanol. The diesel oil filter paper and the preparation method thereof have the beneficial effects of moderate tightness, high inherent strength, high bursting strength, high curability, high water resistance, high oil resistance and convenience and safety in use.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a diesel filter paper and a preparation method thereof. Background technique [0002] Engine oil filter paper is a functional paper that has a certain stiffness and strength after resin impregnation and heat curing treatment, and can withstand a certain pressure difference. At present, the material of automotive diesel filter paper is mainly polymer-coated paper. The nature of the material determines the performance and service life of the diesel filter paper, while the base paper of the oil filter paper made of natural fiber raw materials is loose, low in tightness, and low in inherent strength, which is difficult to withstand the impact of oil in the system and cannot meet the requirements of the filter element during use. performance requirements. Moreover, the oil filter paper made of paper generally has poor curability, water resistance and oil resistance. For exa...
