Nanometer Cr2O3 loaded two-layer composite fuel oil filter paper and preparation method thereof

Abstract

The invention discloses nanometer Cr2O3 loaded two-layer composite fuel oil filter paper and a preparation method thereof. The nanometer Cr2O3 loaded two-layer composite fuel oil filter paper is characterized by being prepared from, by weight, 1-3 parts of cotton fiber, 10-20 parts of hardwood pulp fiber, 1-3 parts of soybean fiber, 10-20 parts of conifer pulp fiber, 10-20 parts of polyester fiber, 10-20 parts of sepiolite nanometer fiber, 1-2 parts of nanometer Cr2O3, 3-5 parts of Fe2O3, 5-10 parts of TiO2, 4-8 parts of MgO, 25-35 parts of silane coupling agent KH560, 15-20 parts of polyoxyethylene water solution, 2-4 parts of titanate coupling agent DHZ201, 50-60 parts of isopropanol, 5-10 parts of styrene-acrylic emulsion and an appropriate amount of ylate emulsion. The gap between layers is improved, the obvious porosity gradient is reserved, and filter efficiency is improved; the filter paper is crumpled, the contact area of fuel oil and the filter paper is increased, and filter efficiency is further improved; the oxygen dissolving rate of fuel oil is increased by means of nanometer Cr2O3, combustion is more sufficient, and produced toxic gas is reduced.

Description

technical field [0001] The invention relates to a fuel filter paper, which belongs to the field of filter materials, in particular to a nano-Cr loaded filter paper 2 o 3 Double-layer composite fuel filter paper and 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...

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
