Abstract

The invention relates to an ultrathin high-permeability oil filter paper and a preparation method thereof. The filter paper is prepared with the raw materials of hemp pulp, chemical fiber, a wet strength agent and bamboo charcoal powder. Through the steps of pulp beating treatment, auxiliary agent addition, bamboo charcoal powder addition, papermaking and cutting, the ultrathin high-permeability oil filter paper is obtained. The filter paper and the production method have the following advantages: the produced ultrathin high-permeability oil filter paper is ultrathin and has low basis weight; the produced paper has stable basis weight, high air permeability, good filtering and absorption performance, good dry and wet strength, good bursting strength, good high-temperature resistance, good folding endurance, good acid and alkali resistances, good solvent resistance, and good application effect. The filter paper and the production method are suitable for popularization.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to an ultra-thin high-permeability oil filter paper and a production method thereof. Background technique [0002] Ultra-thin high-permeability oil filter paper is mainly used in high-end industries such as aviation, advanced machine tools, and precision instruments to filter refined oils. [0003] Ultra-thin high-permeability oil-filter paper has high performance requirements and high technical difficulties. The ultra-thin high-permeability oil-filter paper currently on the market has problems such as low basis weight paper that is difficult to make, unstable paper quantity produced, uneven thickness, and poor paper quality uniformity. Poor air permeability, poor filtration and absorption effect, low dry and wet strength, easy to break when used, not resistant to high temperature, not resistant to folding, not resistant to water, not resistant to alkali, not resistant to acid, poor solve...
