Problems solved by technology

[0004] In Li Yanxia's "Design of Organic-Inorganic Composite Filter Material", a single-layer organic-inorganic composite filter material was synthesized by using wood pulp and synthetic fibers. The gradient of pores is not obvious enough, and the filtration accuracy is not good. There is also room for improvement in strength and fire resistance

Abstract

The invention discloses high-strength and large-contact-area dual-layer composite fuel oil filter paper and a method for producing the same. The high-strength and large-contact-area dual-layer composite fuel oil filter paper is characterized in that the filter paper is produced by using the following raw materials in parts by weight: 3 to 5 parts of glass fiber, 10 to 20 parts of hardwood pulp fiber, 3 to 5 parts of polypropylene fiber, 10 to 20 parts of coniferous pine wood pulp fiber, 10 to 20 parts of polyester fiber, 10 to 20 parts of sepiolite nanofiber, 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 silane coupling agent KH560, 15 to 20 parts of polyoxyethylene aqueous solution, 2 to 4 parts of 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. By performing crumpling treatment to the filter paper, the contact area between fuel oil and the filter paper is increased and the filter efficiency is further improved;and by cooperatively adding polypropylene fiber and glass fiber, the strength of the fuel oil filter paper is 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 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...
