Anticorrosive filter paper and preparation method thereof

Abstract

The invention discloses an anticorrosive filter paper. The anticorrosive filter paper comprises the following raw materials by weight: 65 to 70 parts of waste paper pulp, 40 to 50 parts of slag slurry, 6 to 8 parts of an acrylic emulsion, 12 to 18 parts of a cotton fiber, 8 to 10 parts of a glass fiber, 2 to 3 parts of fatty acid polyethylene glycol ester, 1 to 2 parts of nanometer titanium dioxide, 2 to 3 parts of nanometer zinc oxide, 1 to 2 parts of dibutyl phithalate, 1 to 2 parts of anilmomethyl triethoxy silane, 0.1 to 0.2 part of ethylene glycol ethyl ether, 0.3 to 0.5 part of alkylolamide, 16 to 20 parts of a VAE emulsion DA101, 2 to 3 parts of glycerin, 0.4 to 0.6 part of 1,2-aminoazophenylene, 1 to 2 parts of ethylene glycol tert-butyl ether, 1 to 2 parts of sodium alkyl benzene sulfonate and a proper amount of water. The filter paper produced in the invention has high filterability, a long service life, environment friendliness and stable quality; an impregnation liquid used in the invention has good cohesiveness and film forming ability; and after impregnation, the filter paper has enhanced dry and wet strength and toughness, and filtration efficiency of a filter is improved.

Description

technical field [0001] The invention mainly relates to a filter paper, in particular to an anti-corrosion filter paper and a preparation method thereof. Background technique [0002] The filter is an important part of the engine. Its function is to filter out particles such as dust and mechanical impurities in the air, diesel oil, and engine oil entering the engine, so as to reduce the engine cylinder liner piston ring, crankshaft connecting rod kinematic pair and high-pressure oil pump plunger. Wear of even parts, optimize the combustion process of the engine, and reduce the emission of organic pollutants such as carbon monoxide. The traditional production of filter paper has problems such as low filtration performance, short service life, and unstable quality of filter paper, which greatly limits the improvement of filter filtration efficiency and also affects the improvement of engine performance. It is difficult to meet the current requirements of people. The pu...
