Abstract

The invention discloses high-strength and high-contact area double-layer composite fuel filter paper and a preparation method thereof. The high-strength and high-contact area double-layer composite fuel filter paper is characterized by being prepared from the following raw materials in parts by weight: 3 to 5 parts of glass fibers, 10 to 20 parts of hardwood pulp fibers, 3 to 5 parts of polypropylene fibers, 10 to 20 parts of coniferous pine wood pulp fibers, 10 to 20 parts of polyester fibers, 10 to 20 parts of sepiolite nano fibers, 2 to 4 parts of white carbon black, 3 to 5 parts of Fe2O3, 5 to 10 parts of TiO2, 4 to 8 parts of MgO, 25 to 35 parts of a silane coupling agent KH560, 15 to 20 parts of a polyoxyethylene aqueous solution, 2 to 4 parts of a titanate coupling agent DNZ201, 50 to 60 parts of isopropanol, 5 to 10 parts of styrene-acrylic emulsion and a proper amount of polyacrylate emulsion. According to the high-strength and high-contact area double-layer composite fuel filter paper, a gap between one layer and the other layer is improved; furthermore, the obvious porosity gradient is retained, and the filter efficiency is improved; the filter paper is subjected to crumbling treatment, so that the contact area of fuel and the filter paper is enlarged, and the filter efficiency is further improved; by the cooperated adding of the polypropylene fibers and the glass fibers, the strength of the fuel filter paper is enhanced.

Description

technical field [0001] The invention relates to a fuel filter paper, which belongs to the field of filter materials, in particular to a double-layer composite fuel filter paper with high strength and 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 pho...
