Method for manufacturing bamboo fiber filter paper

Abstract

The invention discloses a method for manufacturing bamboo fiber filter paper, and the method comprises the following steps: mixing bamboo fiber crystals, acrylic resin particles with a porous structure and an aqueous solution of a foaming agent; under the condition of high temperature, introducing a gas to form a gel-like crosslinked polymer; drying the gel-like crosslinked polymer; pulverizing the crosslinked polymer, adding carboxymethyl cellulose, mixing with a large amount of hot water for agglomeration, and recovering to a hydrogel product again to form an aqueous solution; pulverizing the crosslinked polymer, adding carboxymethyl cellulose, and providing a base material to be immersed in the aqueous solution; spraying a surface cross-linking agent to the surface of the base materialafter the impregnation is completed; and drying. The method has the beneficial effects that the gel-like crosslinked polymer is formed by combining the bamboo fiber crystals with the acrylic resin particles, and then the gel-like crosslinked polymer is combined with the carboxymethyl cellulose after the gel-like crosslinked polymer is formed, the acrylic resin can help the bamboo fiber and the carboxymethyl fiber to be more combined, and the filtering capability of the filter paper can be improved by soaking in a new aqueous solution.

Description

technical field [0001] The invention relates to a method for making filter paper, in particular to a method for making bamboo fiber filter paper. Background technique [0002] Filter paper is the core material in the oil filter. How to obtain a filter paper that separates water and oil is the core of improving the filtration quality. Therefore, more and more manufacturers have conducted a lot of research on how to obtain high-quality filter paper. [0003] For example, on July 09, 2019, Chinese Patent No. 201910256675.5 disclosed a multi-layer filter paper and its preparation method, wherein the steps of the preparation method are: 1) Dense layer slurry preparation: prepare the raw material plant according to the composition of the dense layer Fiber, synthetic fiber with single melting point, mixed with water, beating, to obtain dense layer slurry; 2) loose layer slurry preparation: prepare various raw materials according to the formula composition of loose layer, mix with ...

[0004] The above-mentioned filter paper is made of two kinds of filter papers with different densities, and then sizing for bonding. The experiment shows that in less than 48 hours in the conventional experiment, the components of the two layers of glue react with certain components of the engine oil. Causing the weakening of cohesion, the loose layer and the tight layer are separated
