Abstract
The invention discloses acetate fiber paper. The acetate fiber paper is prepared from the following raw materials in part by weight: 70 to 75 parts of hemp pulp fiber, 10 to 15 parts of reed pulp fiber, 25 to 28 parts of acetate fiber, 1 to 2 parts of modified nano sepiolite powder, 1 to 2 parts of modified nacrite, 1 to 2 parts of pure acrylic emulsion, 1 to 2 parts of sodium-based bentonite, 0.5 to 1 part of mica powder, 0.5-0.8 part of carboxymethyl cellulose, 1-2 parts of aluminum silicate, 1-2 coco fatty acid diethanol amide and 0.2 to 0.4 part of wet strength agent PAE. The filter paper has the advantages of high water permeability, large filtering area, small maximum aperture, high filtering precision, high water resistance and the like, has stable performance indexes under the work conditions of normal temperature and high temperature, and has better temperature resistance and filtering effects.
Description
Technical field
The present invention relates to the filter paper field, exactly is a kind of acetate fiber filter paper.
Background technology
As a kind of effective filter medium, filter paper has been widely used in every field.Different according to the kinds of fibers that forms filter paper, the performance of filter paper, purposes are also different, are useful on the common filter paper of general occasion, be used under the high temperature glass fiber filter paper, also have ultra-clean with polypropylene filter paper etc.According to filter paper impregnation whether, can be divided into two large classes, i.e. impregnation filter paper and non-impregnation filter paper.Impregnation filter paper is divided into again curing filter paper and non-curing filter paper.
Along with improving constantly of filter requiring, anyly plant fibrous filter paper and all more and more be difficult to satisfy requirement on using by single, so the filter paper that is formed by multiple fiber combinations arises at the historic moment.Fiber commonly used in the filter paper production has wood fibre, chemical fibre, glass fibre etc.
