Abstract

The invention discloses an efficient automobile filter paper and a preparation method thereof. The efficient automobile filter paper is composed of the following raw materials, by weight: 70-80 parts of softwood pulp, 20-30 parts of polybenzimidazole fiber, 10-20 parts of quartz glass fiber, 2-5 parts of modified bentonite, 1-3 parts of nanometer calcium, 2-4 parts of diatomaceous earth, 1-2 parts of nanometer titania, 0.5-0.8 part of decabromodiphenyl ether, 2-3 parts of modified polyvinyl acetate emulsion, 0.5-1 part of glycerol triglyceride, 0.5-1 part of a silane coupling agent KH550, 0.4-0.8 part of sodium lauryl sulfate, and 2-5 parts of polyethylene imine. The filter paper prepared by the invention has advantages of good water permeability, large filtering area, small maximum pore size, high filtration precision, strong durability, high temperature resistance, high tensile strength and good water resistance, has filtering efficiency reaching 99.99%, stable performance index at room temperature and high temperature, and good temperature resistance and filtering effect.

Description

technical field [0001] The invention relates to filter paper for a filter, in particular to a high-efficiency automobile filter paper and a preparation method thereof. Background technique [0002] Car 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 a car. Then, the filter is The "lungs" of the car are 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 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 performance such as high temperature resi...
