Problems solved by technology

The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency and can only filter out 50-60% of impurities in the oil; in addition, the existing filter paper also has poor high temperature resistance, poor water resistance, and poor tensile strength. Shortcomings such as low and poor burst resistance limit the service life of filter paper

Embodiment

[0017] A silica gel loaded zirconia air filter paper, made of the following raw materials in parts by weight: 80 parts of wood pulp, 30 parts of hemp pulp, 20 parts of ceramic fiber, 5 parts of modified silica gel, 3 parts of nano calcium carbonate, 4 parts of activated carbon, nano 2 parts of alumina, 0.8 parts of ammonium polyphosphate, 3 parts of pure acrylic emulsion, 2 parts of polyethylene glycol, 1 part of tricresyl phosphate, 1 part of aniline methyl triethoxysilane, 0.8 parts of sodium lauryl sulfate, modified 5 parts of non-toxic polyethyleneimine.

[0018] The modified silica gel is loaded with zirconia on the silica gel, and the specific modification process is as follows: first put the silica gel into a 0.15mol / L zirconium oxychloride solution, and dip it in a constant temperature water bath oscillator with a rotation speed of 140r / min at a temperature of 70°C, take out and filter after impregnation, transfer the filter cake into a crucible, and finally roast ...

Abstract

The invention discloses zirconium oxide-loaded silicone air filtration paper and a preparation method thereof. The air filtration paper comprises the following raw materials in part by weight: 70 to 80 parts of wood pulp, 20 to 30 parts of jute pulp, 10 to 20 parts of ceramic fiber, 2 to 5 parts of modified silicone, 1 to 3 parts of nano calcium carbonate, 2 to 4 parts of activated carbon, 1 to 2 parts of nano aluminium oxide, 0.5 to 0.8 part of ammonium polyphosphate, 2 to 3 parts of acrylic latex, 1 to 2 parts of polyethylene glycol, 0.5 to 1 part of tricresyl phosphate, 0.5 to 1 part of anilmomethyl triethoxy silane, 0.4 to 0.8 part of sodium lauryl sulfate and 2 to 5 parts of modified polyethyleneimine. The prepared filtration paper has the advantages of high water permeability, filtration accuracy, bursting strength and tensile strength, large filtration area, high temperature resistance and the like, the maximum aperture is small, and the filtration efficiency reaches 99.98 percent; and the filtration paper has a stable performance index under the working conditions of normal temperature and high temperature and has relatively good heat resistance and filtration effects.

Description

technical field [0001] The invention relates to a filter paper, in particular to a silica gel loaded zirconia air filter paper and a preparation method thereof. Background technique [0002] Automobile air filter paper is the core material for manufacturing automobile engine air filters. Since the air filter is located in the intake system of the engine, and the engine usually emits a lot of heat when it is working, it is generally hoped that this air filter medium has good performance. Excellent filtration performance and high filtration efficiency, as well as certain high temperature resistance, water resistance and burst resistance. The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency and can only filter out 50-60% of impurities in the oil; in addition, the existing filter paper also has poor high temperature resistance, poor water resistance, and poor tensile strength. Shortcomings such as low and poor bu...
