Abstract

The invention discloses active carbon doped double-layer composite fuel oil filter paper with a large contact area and a preparation method thereof. The filter paper is characterized by being prepared from the following raw materials in parts by weight: 2 to 4 parts of ceramic fiber, 10 to 20 parts of broad leaf wood pulp cellulose, 3 to 5 parts of active carbon, 10 to 20 parts of coniferous pine wood pulp cellulose, 10 to 20 parts of polyester fiber, 1 to 3 parts of silica gel, 10 to 20 parts of sepiolite nanometer fiber, 3 to 5 parts of Fe2O3, 5 to 10 parts of TiO2, 4 to 8 parts of MgO, 25 to 35 parts of silane coupling agents KH560, 15 to 20 parts of polyoxyethylene water solution, 2 to 4 parts of titanate coupling agents DNZ201, 50 to 60 parts of isopropanol, 5 to 10 parts of styrene-acrylic emulsion and a proper amount of ylate emulsion. The filter paper has the advantages that the void between the layers is improved; meanwhile, the obvious void gradient is reserved; the filtering efficiency is improved; Fe2O3 and TiO2 have an oxygenolysis effect on organic matters and inorganic matters in automobile exhaust; the filter paper is subjected to crumpling treatment, so that the contact area of the fuel oil and the filter paper is increased; the filtering efficiency is further improved; active carbon is matched and added, so that the filter paper achieves an excellent filtering effect.

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 activated carbon doped with 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 ...
