Bamboo load-bearing chitosan industrial filter paper for automobiles and preparation method of bamboo load-bearing chitosan industrial filter paper

Abstract

The invention discloses bamboo load-bearing chitosan industrial filter paper for automobiles, which comprises the following raw materials by weight: 50 to 60 parts of bamboo pulp, 40 to 50 parts of polytetrafluoroethylene fiber, 10 to 20 parts of glassfiber, 2 to 5 parts of modified bamboo, 1 to 3 parts of carbon molecular sieve, 2 to 4 parts of light calcium carbonate, 1 to 2 parts of nano alumina, 2 to 3 parts of modified water-soluble nano silica sol, 1 to 2 parts of styrene-acrylic emulsion, 0.5 to 0.8 part of antimony trioxide powder, 3 to 4 parts of dibutyl phthalate, 0.5 to 1 part of fatty alcohol-polyoxyethylene ether, 0.5 to 1 part of silane coupling agent KH792, 0.4 to 0.8 part of sodium laurylsulfate, 0.5 to 1 part of antioxidant 1010 and 4 to 6 parts of wet strength agent PAE. The filter paper prepared according to the invention has the advantages of good water permeability, large filtering area, small maximum pore size, high filtering precision, high temperature resistance, high water resistance and the like; the filtering efficiency reaches 99.96%, the performance index is stable under normal-temperature and high-temperature conditions, and the filter paper has better temperature resistance and a good filtering effect.

Description

technical field [0001] The invention relates to a filter paper for automobiles, in particular to a bamboo charcoal-loaded chitosan automobile industry filter paper and a preparation method thereof. Background technique [0002] Automobile industry filter paper 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 a car. Then, the filter is It is the "lung" of the car, and it is responsible for removing impurities in the car, preventing engine parts from wearing out, and prolonging its life. The filter material of automobile filter is mostly filter paper, so the quality of the filter paper directly affects the filtration efficiency of the filter. The existing filter paper has the following disadvantages: [0003] (1) Low filtration efficiency and poor filtration accuracy lead to low filtration efficiency of the filter, which can only filter out 50-60% o...

AI Technical Summary

Problems solved by technology

[0003] (1) Low filtration efficiency and poor filtration accuracy lead to low filtration efficiency of the filter, which can only filter out 50-60% of impurities;

[0004] (2) Poor performance such as high temperature resistance, water resistance, and burst resistance, resulting in short service life;

[0005] (3) Large fluctuations in quality and poor stability
