Abstract
The invention discloses a preparation method for modified kaolin-containing filter paper for an air filter. The filter paper is prepared from the following raw materials in part by weight: 2 to 4 parts of modified kaolin, 1 to 2 parts of modified nano dickite powder, 0.4 to 0.6 part of magnesium hydrate, 0.2 to 0.4 part of talcpowder, 1 to 2 parts of dispersing agent NNO, 80 to 90 parts of bamboo pulp fiber, 25 to 30 parts of polytetrafluoroethylene fiber, 0.2 to 0.4 part of polyarylether (PAE) wet strength agent, 1 to 2 parts of polyvinyl acetate emulsion adhesive, 0.5 to 1 part of chlorinated paraffin, and 0.5 to 1 part of ammonium dihydrogen phosphate. The obtained filter paper has the advantages of high water permeability, large filter area, small maximum hole diameter, high filter accuracy, high water resistance and the like; and under the work conditions of normal temperature and high temperature, the filter paper has a stable performance index, and good temperature-resisting and filtering effects.
Description
Technical field
The present invention relates to the automobile filter field, exactly is the preparation method that a kind of air filter that contains modified kaolin is used filter paper.
Background technology
In a system, with a kind of medium of porous the solia particle in liquid or the gas is removed, be called filtration, for the annex of finishing such mission employing is called cleaner.Cleaner includes air filter, oil filter, fuel filter, is referred to as three filters.
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.
Summary of the invention
The object of the present invention is to provide the preparation method of the good air filter usefulness filter paper that contains modified kaolin of a kind of resistance to elevated temperatures.
Above-mentioned purpose realizes by following scheme:
A kind of air filter that contains modified kaolin preparation method of filter paper is characterized in that: may further comprise the steps:
