[0002] Diesel filter is a kind of fuel filter. It is a device used to filter other solid impurities mixed in diesel. The filter element plays the role of filtering diesel. The filter element of diesel filter is mostly made of filter paper. , so the quality of the filter paper directly affects the efficiency of the filter element to filter diesel oil. The existing filter paper has poor adsorption and low filtration efficiency. It can only filter out 60% of the impurities in the oil, and the impurities that are larger or smaller than the pores of the paper filter element are all There is no permanent filtering effect, and it can only play a permanent filtering effect on those impurities that are equivalent to the micropores of the paper filter element and embedded in the micropores of the paper filter element; in addition, the existing filter paper also has poor high temperature resistance and poor water resistance. Disadvantages such as low tensile strength limit the service life of filter paper

Embodiment
[0017] A filter paper for a diesel filter mixed with hollow polyester staple fiber, made of the following raw materials in parts by weight: hardwood pulp 70, hollow polyester staple fiber 30, quartz glass fiber 20, modified perlite 5, heavy calcium carbonate 3 , activated clay 3, nano silicon dioxide 2, zinc borate 0.8, modified water-soluble epoxy resin emulsion 2, poly N-vinyl pyridine 2, fatty alcohol polyoxyethylene ether 1, vinyl tris (β-methoxy Ethoxy) silane 1, sodium lauryl sulfate 0.8, wet strength agent PAE 5.
[0018] The modified perlite is prepared by the following method: first grind the perlite and pass it through a 200-mesh sieve, then heat it to expand, then gradually cool it to normal temperature, add an appropriate amount of ammonia water for pretreatment, and add the pretreated pearlite Add 3% silane coupling agent KH550 and 5% absolute ethanol to the rock, heat and stir at 100°C for 30 minutes, dry and crush to obtain modified perlite.

Abstract
The invention discloses hollow polyester staple fiber doped filter paper for a diesel filter and a preparation method for the filter paper. The hollow polyester staple fiber doped filter paper is prepared from the following raw materials in part by weight: 60 to 70 parts of hardwood pulp, 20 to 30 parts of hollow polyester staple fiber, 10 to 20 parts of quartz glass fiber, 2 to 5 parts of modified perlite, 1 to 3 parts of heavy calcium carbonate, 2 to 3 parts of activated clay, 1 to 2 parts of nano silica, 0.5 to 0.8 part of zinc borate, 1 to 2 parts of modified water-soluble epoxy resin emulsion, 1 to 2 parts of poly N-vinylpyridine, 0.5 to 1 part of fatty alcohol-polyoxyethylene ether, 0.5 to 1 part of vinyl tri(beta-methoxyl ethoxyl) silane, 0.4 to 0.8 part of sodium laurylsulfate and 2 to 5 parts of wet strength agent PAE. The filter paper prepared by the method has the advantages of high water permeability, large filtering area, small maximum aperture, high filtering precision, high bursting strength, high-temperature resistance and the like, reaches the filtering efficiency of 99.98 percent, has stable performance indexes under the work conditions of normal temperature and high temperature, and has better temperature resistance and filtering effects.
