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

Embodiment

[0019] An environmentally friendly high-efficiency filter paper, made of the following raw materials in parts by weight: 50 parts of softwood pulp, 40 parts of waste paper pulp, 30 parts of high-silica glass fiber, 5 parts of modified vermiculite, 3 parts of zeolite molecular sieve, nano 4 parts of calcium, 2 parts of modified fly ash, 3 parts of water-soluble silicone resin emulsion, 2 parts of water-soluble polytetrafluoroethylene emulsion, 0.8 parts of ammonium polyphosphate, 4 parts of triacetin, 1 part of diethanolamide, Silane coupling agent KH560 1 part, sodium lauryl sulfate 0.8 part, antioxidant DSTP 1 part, polyethyleneimine 6 parts.

[0020] The modified vermiculite is prepared by the following method: first grind the vermiculite into a 120 mesh powder, add an appropriate amount of 6mol / L hydrochloric acid solution, stir with an electric stirrer for 30min, let stand for 12h, suction filter, and use distilled water to Neutral, then add 1% vinyltriethoxysilane and 2% ...

Abstract

The invention discloses an environment-friendly efficient filter filtering paper. The environment-friendly efficient filter filtering paper is prepared by the following raw materials in part by weight: 40-50 parts of softwood pulp, 30-40 parts of waste paper pulp, 20-30 parts of high-silica glass fiber, 2-5 parts of modified vermiculite, 1-3 parts of zeolite molecular sieve, 2-4 parts of nanometer calcium, 1-2 parts of modified pulverized fuel ash, 2-3 parts of water-solubility organic silicon resin emulsion, 1-2 parts of water-solubility polytetrafluoroethylene emulsion, 0.5-0.8 parts of ammonium polyphosphate, 3-4 parts of glycerol triacetate, 0.5-1 parts of diethanolamide, 0.5-1 parts of silane coupling agent KH560, 0.4-0.8 parts of sodium dodecyl sulfate, 0.5-1 parts of antioxidant DSTP, and 4-6 parts of polyethylenimine. The filtering paper prepared by the method provided by the invention has the advantages of being good in water permeability, large in filtering area, small in maximum diameter of hole, high in filtering precision, strong in bursting strength, high-temperature-resistant, good in water resistance and the like, can achieve the filtering efficiency by 99.98%, has stable performance index at atmospheric and high-temperature working conditions, as well as better temperature resistance and filtering effects.

Description

technical field [0001] The invention relates to filter paper for a filter, in particular to a filter paper for an environment-friendly high-efficiency filter and a preparation method thereof. Background technique [0002] Filter paper is a filter material for car 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, the filter It is the "lung" of the car, which 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% of impurities; [0004] (2) Poor pe...
