Bamboo pulp filter paper for electric spray gasoline filter and preparation method of bamboo pulp filter paper

Abstract

The invention discloses bamboo pulp filter paper for an electric spray gasoline filter and a preparation method of the bamboo pulp filter paper. The bamboo pulp filter paper comprises, by weight, 60-70 parts of bamboo pulp, 20-30 parts of wood pulp, 10-20 parts of alumina silicate fiber, 2-5 parts of modified bentonite, 1-3 parts of nano calcium, 2-4 parts of activated carbon, 1-2 parts of activated aluminum oxide, 0.5-0.8 part of hexabromocyclododecane, 1-2 parts of modified styrene-acrylic emulsion, 1-2 parts of polyvinylpyrrolidone, 0.5-1 part of fatty glyceride, 0.5-1 part of silane coupling agent KH792, 0.4-0.8 part of sodium lauryl sulfate, and 2-5 parts of melamino-formaldehyde resin. The bamboo pulp filter paper prepared is good in water permeability, large in filtering area, small in maximum hole diameter, high in filtering precision, strong in bursting strength, high in temperature resistance and the like, has stable performance index under normal-temperature and high-temperature working conditions and is provided with good temperature resistance and filtering effects, and filtering efficiency of the bamboo pulp filter paper can reach 99.96%.

Description

technical field [0001] The invention relates to filter paper for a filter, in particular to a bamboo pulp filter paper for an electric injection gasoline filter and a preparation method thereof. Background technique [0002] The EFI gasoline filter is a kind of gasoline filter in the fuel filter. It is a device used to filter out other solid impurities mixed in gasoline. The filter element plays the role of filtering gasoline. The gasoline filter Most of the filter elements are made of filter paper, so the quality of the filter paper directly affects the efficiency of the filter element to filter gasoline. The existing filter paper has poor adsorption and low filtration efficiency. It can only filter out 50-60% of impurities in gasoline. Impurities that are smaller than the micropores of the paper filter element cannot have a permanent filtering effect, and can only permanently filter out those impurities that are equal to the micropores of the paper filter element and embed...

[0002] The EFI gasoline filter is a kind of gasoline filter in the fuel filter. It is a device used to filter out other solid impurities mixed in gasoline. The filter element plays the role of filtering gasoline. The gasoline filter Most of the filter elements are made of filter paper, so the quality of the filter paper directly affects the efficiency of the filter element to filter gasoline. The existing filter paper has poor adsorption and low filtration efficiency. It can only filter out 50-60% of impurities in gasoline. Impurities that are smaller than the micropores of the paper filter element cannot have a permanent filtering effect, and can only permanently filter out those impurities that are equal to the micropores of the paper filter element and embedded in the micropores of the paper filter element; in addition, the existing filter paper It also has the disadvantages of poor high temperature resistance and poor burst resistance, which limits the service life of filter paper
