Abstract

The invention discloses a nanometer quantitative filter paper. The nanometer quantitative filter paper is made from, by weight, 30-80 parts of bamboo pulp, 5-40 parts of a Juncus effusus pulp, 30-80 parts of softwood pulp, 30-80 parts of cotton pulp, 0.2-5 parts of lignin, 1-5 parts of cellulose nano-crystals, 20-40 parts of water-soluble polyethelene alcohol fibers, 0.5-3 parts of a wet strength agent, 0.2-0.8 parts of a dispersant and 0.1-0.3 parts of an antifoaming agent. Cellulose nanofibers are obtained through adding all above pulps to an ultrahigh pressure micro-jet nanodisperser, are harder and lighter than iron, and can be used in the filter paper industry to realize paper lightening, and the added cellulose nano-crystals can be closely combined with paper pulp fibers in order to improve the combination force among the paper pulp fibers.

Description

technical field

[0001] The invention relates to the technical field of filter paper, in particular to a nano quantitative filter paper and a preparation method thereof. Background technique

[0002] Quantitative filter paper belongs to cellulose filter paper, which is a kind of paper with good filtration performance. The paper is loose and has strong absorption performance for liquids. Therefore, it is often used as a filter medium in chemical analysis experiments to separate solids and liquids. In the manufacturing process, the pulp is treated with hydrochloric acid and hydrofluoric acid, and washed with deionized water to remove most of the paper fibers, so there is little residual ash after burning, which has almost no effect on the analysis results, and is suitable for precision quantitative analysis. At present, the filtration speed, filtration accuracy and stability of quantitative filter paper need to be further unified, and the sheets of quantitative filter paper ar...
