Stable-quality zirconia-supported air filter paper for automobiles, and making method thereof

Abstract

The invention discloses a stable-quality zirconia-supported air filter paper for automobiles. The stable-quality zirconia-supported air filter paper is made by using the following raw materials, by weight, 38-41 parts of a bagasse pulp, 54-58 parts of a broad leaf wood pulp, 1-2 parts of sweetcane bark, 2-4 parts of carboxymethyl cellulose, 0.4-0.6 parts of polyoxyethylene fatty alcohol ether, 6-8 parts of liquid silicone rubber, 2-3 parts of attapulgite, 2-3 parts of zirconia, 0.6-0.8 parts of cassava starch, 0.4-0.6 parts of calcium chloride, 0.2-0.3 parts of sesbania gum, 2-4 parts of glycerin, 5-6 parts of alkyl ketene dimer, 1-2 parts of an assistant and a proper amount of water. The zirconia-supported air filter paper has the characteristics of ventilation, small filtering resistance and stable quality; the addition of zirconia and the like makes the air filter paper have a good adsorption effect, a high temperature resistance and stable properties; and the addition of plant particles and the assistant increases the porosity of the filter paper, realizes uniform dispersion of adsorbed components, and improves the filter performance.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to a zirconia-loaded automobile air filter paper with stable quality 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 paper filter layer will swell after absorbing moisture, resulting in a decrease in the pore size and porosity of the filter paper, resulting in an increase in filter resistance and a decrease in vehicle power. It also has poor high temperature resistance, low tensile strength, and poor burst resistance....

AI Technical Summary

Problems solved by technology

The paper filter layer will swell after absorbing moisture, resulting in a decrease in the pore size and porosity of the filter paper, resulting in an increase in filter resistance and a decrease in vehicle power. It also has poor high temperature resistance, low tensile strength, and poor burst resistance. Unstable quality and other shortcomings limit the service life of filter paper
