Abstract

The invention discloses graphene-doped large-contact-area dual-layer composite fuel oil filter paper and a preparation method thereof. The filter paper is characterized by being prepared from, by weight, 2-4 parts of graphene, 10-20 parts of hardwood pulp fibers, 1-2 parts of bentonite, 10-20 parts of coniferous pine pulp fibers, 10-20 parts of polyester fibers, 10-20 parts of sepiolite nanofibers, 1-2 parts of citric acid, 3-5 parts of Fe2O3, 5-10 parts of TiO2, 4-8 parts of MgO, 25-35 parts of a silane coupling agent KH560, 15-20 parts of a polyoxyethylene aqueous solution, 2-4 parts of a titanate coupling agent DNZ201, 50-60 parts of isopropanol, 5-10 parts of styrene-acrylic emulsion and an appropriate amount of polyacrylate emulsion. According to the filter paper, gaps among layers are improved, the obvious porosity gradient is retained, and the filter efficiency is improved; by conducting creasing treatment on the filter paper, the contact area of fuel oil and the filter paper is increased, and then the filter efficiency is further improved; by cooperatively adding the graphene, the glossiness and the tensile property of the filter paper are improved.

Description

technical field [0001] The invention relates to a fuel filter paper, which belongs to the field of filter materials, in particular to a graphene-doped double-layer composite fuel filter paper with a high contact area and a preparation method thereof. Background technique [0002] Fuel filter paper is a filter paper impregnated with resin. Its main function is to remove impurities in fuel, prevent excessive wear of engine parts and prolong its life. Fuel treatment technology is an improvement technology implemented mainly for fuel. The implementation of this method improves the combustion efficiency of the engine and reduces pollutant emissions. [0003] Photocatalytic degradation technology is an application technology that uses photo-semiconductor materials with photocatalytic function to carry out catalytic degradation reactions. Photocatalytic degradation materials will generate free electrons and holes under the irradiation of ultraviolet rays, so they have strong phot...
