Abstract
The invention relates to high-adsorptivity filter paper and a preparation method thereof. The high-adsorptivity filter paper disclosed by the invention is composed of the following raw materials by weight: 100-120 parts of softwood pulp, 12-14 parts of bamboo charcoal powder, 2-3 parts of chlorinated paraffin, 1-3 parts of ceramic powder, 1-3 parts of light calcium carbonate, 1-2 parts of alum powder, 1-2 parts of 1,4-cyclohexanedimethanol, 1-2 parts of polypropylene adipate, 0.3-0.5 part of ammonium dihydrogen phosphate, 2-3 parts of sodium alginate, 0.8-1 part of ethylene bis-stearamide, 0.4-0.5 part of ceric oxide, 10-12 parts of rosin, 3-4 parts of chitosan, 3-5 parts of absolute ethyl alcohol, 1-2 parts of sodium carboxymethylcellulose, 0.2-0.4 part of diisopropylbenzene peroxide and a proper amount of water. A large amount of bamboo charcoal powder is doped in the filter paper and completely combined with the paper pulp by grinding. The bamboo charcoal has relatively strong adsorptivity. The highly doped bamboo charcoal powder greatly increases the adsorptivity of the filter paper; and at the same time, the capacity for adsorbing heavy metal particles and harmful particles is greatly increased.
Description
Technical field
The present invention relates generally to a kind of filter paper, relates in particular to filter paper of filter of a kind of high adsorption and preparation method thereof.
Background technology
Engine has air, machine oil, three kinds of cleaners of fuel oil, generally is called " three filters ".They undertake respectively the filtration of engine aspirating system, lubricating system and combustion system medium.The filter paper of filter of traditional mode of production is large because of its filter paper aperture, lack of homogeneity, filter efficiency is low, the impurity harmful to engine can not be carried out to effective filtering, cause the engine premature wear, filter paper of filter with dipping emulsion now by pure dissolubility to water-soluble development, water-soluble dipping emulsion commonly used is as polyvinyl acetate copolymerization emulsion, benzene emulsion and pure acrylate series emulsion etc., wherein benzene emulsion is the most frequently used, but the filter paper glued membrane fragility after the benzene emulsion dipping is larger, caking property to fiber surface in filter paper is not good, and the function monomer consumption is large, cost is high, particularly deflection is high and can not in environment, degrade.
