Abstract

The invention provides a preparation method of dissolving-resistant oil-water separation filter paper, and the preparation method comprises the following steps: obtaining raw materials; adding nano-diatomaceous earth, calcium carbonate, water-soluble phenolic resin, coconut fibers, saw dust, citric acid, zinc nitrate and microcrystalline cellulose into mixed slurry, and heating to 70-80 DEG C; after defibering by a defibering machine, grinding pulp, performing papermaking according to a conventional papermaking process, forming, squeezing and drying; compared with the prior art, the preparation method comprises the following beneficial effects: by selecting natural cotton fibers, gypsum fibers, and polyester fibers to serve as basic raw materials, the characteristics of oil-water resistance and high temperature resistance of the filter paper are provided, by addition of the saw dust, the environment-friendly performance is improved, and the oil-water separation performance of the filter paper material is effectively improved.

Description

technical field [0001] The invention relates to a preparation method of a dissolution-resistant oil-water separation filter paper, which belongs to the technical field of filter paper preparation. Background technique [0002] Filter paper is a kind of paper with good filtering performance. The paper is loose and has strong absorption performance for liquid. Analytical laboratories often use filter paper as a filter medium to separate solutions from solids. At present, the filter papers produced in my country mainly include quantitative analysis filter paper, qualitative analysis filter paper and chromatography qualitative analysis filter paper. However, these three filter papers are not very effective in filtering oil and water. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a method for preparing a solvent-resistant oil-water separation filter paper, so as to solve the problems raised ...
