Bilayer composite fuel filter paper containing asbestos fibers and preparation method of bilayer composite fuel filter paper containing asbestos fibers

Abstract

The invention discloses bilayer composite fuel filter paper containing asbestos fibers and a preparation method of the bilayer composite fuel filter paper containing the asbestos fibers. The bilayer composite fuel filter paper is characterized by being prepared from the following raw materials in parts by weight: 1 to 3 parts of the asbestos fibers, 10 to 20 parts of hardwood pulp fibers, 10 to 20 parts of coniferous pine wood pulp fibers, 10 to 20 parts of polyester fibers, 10 to 20 parts of sepiolite nanofibers, 1 to 2 parts of shell powder, 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. According to the bilayer composite fuel filter paper disclosed by the invention, by performing crumpling treatment on the filter paper, contact area between fuel and the filter paper is increased, and further the filtering efficiency is improved; by adding the asbestos fibers for matching, high-temperature resistance of the 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 containing asbestos fibers 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 photoredox abilit...

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
