Filter paper doped with viscose-based activated carbon fiber for automobile filter and preparation method of filter paper

Abstract

The invention discloses filter paper doped with viscose-based activated carbon fiber for an automobile filter and a preparation method of the filter paper. The filter paper comprises, by weight, 70-80 parts of wood pulp, 20-30 parts of bamboo pulp, 10-20 parts of mineral cotton fiber, 2-5 parts of the viscose-based activated carbon fiber, 1-3 parts of nano titanium dioxide, 2-4 parts of modified diatomite, 1-2 parts of activated aluminum oxide, 0.5-0.8 part of hexabromocyclododecane, 2-3 parts of water-soluble organic silicon resin emulsion, 1-2 parts of water-soluble acrylic resin emulsion, 0.5-1 part of tributyl citrate, 0.5-1 part of vinyl-tri (beta- methoxy ethyoxyl) silane, 0.4-0.8 part of sodium lauryl sulfate, and 2-5 parts of wet strength agent PAE (polyamide epichiorobydrin resin). The filter paper doped with the viscose-based activated carbon fiber for the automobile filter 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 tensile strength 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, filtering efficiency of the filter paper can reach 99.99%.

Description

technical field [0001] The invention relates to filter paper for a filter, in particular to a filter paper for an automobile filter mixed with viscose-based activated carbon fiber and a preparation method thereof. Background technique [0002] Filter paper for automobile filters is a filter material for automobile filters. It is generally used inside the engine to filter impurities in air, oil and fuel. People often refer to the engine as the "heart" of the car. Then, filter The organ is the "lung" of the car, which is responsible for removing impurities, preventing engine parts from wearing out, and prolonging their life. The filter material of automobile filter is mostly filter paper, so the quality of filter paper directly affects the filtration efficiency of the filter. The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency of the filter. Poor high temperature resistance, poor water resistance, low tensile ...

Problems solved by technology

The filter material of automobile filter is mostly filter paper, so the quality of filter paper directly affects the filtration efficiency of the filter. The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency of the filter. Poor high temperature resistance, poor water resistance, low tensile strength, poor bursting strength and other shortcomings limit the service life of filter paper
