Safe and environment-friendly fuel oil filter paper with good fuel oil resistance stability and preparation method thereof

Abstract

The invention discloses a safe and environment-friendly fuel oil filter paper with good fuel oil resistance stability. The fuel oil filter paper is characterized by being prepared from the following raw materials by weight: 50 to 54 parts of birch pulp, 52 to 57 parts of eucalyptus pulp, 3 to 4 parts of melamino-formaldehyde resin, 0.3 to 0.5 part of sodium dodecyl benzene sulfonate, 1 to 2 parts of dried rosebay leaves, 0.5 to 0.7 part of carragheenan, 0.3 to 0.4 part of flaxseed gum, 3 to 4 parts of quartz sand, 3 to 4 parts of active carbon, 2 to 3 parts of a glass fiber, 1 to 2 parts of ammonium chloride, 5 to 7 parts of polymethyl acrylate, 2 to 3 parts of dioctyl ester, 1 to 2 parts of an auxiliary agent and a proper amount of water. According to the invention, quartz sand, the glass fiber and the like are added and organically combined with the filter paper, so the filter paper has good strength and adsorptivity, water resistance, flame retardation and fuel oil resistance stability; ammonium chloride is added, so the filter paper has a good flame retardation effect; the auxiliary agent is added, which is safe and environment-friendly, small pores are formed in the surface of the filter paper, so adsorptivity is improved and the filter paper has a good filtering effect and long service life.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to a safe and environment-friendly fuel filter paper with good fuel resistance and stability and a preparation method thereof. Background technique [0002] As one of the three filter papers for automobiles, the fuel filter paper is mainly used to filter fuel, clean impurities in fuel, prevent them from entering injection valves and cold starters, reduce mechanical wear, ensure stable engine operation, and improve reliability. In order to ensure the safe and effective operation of the internal combustion engine, the matching filter material must have excellent mechanical properties and a certain resistance to water and fuel, so as to ensure the good filtration performance of the filter paper. Most of the filter papers used in the fuel filter products on the market are ordinary filter papers that can only filter the solid phase pollutants in the fuel, but the erosion of the filter p...

Problems solved by technology

Most of the filter papers used in the fuel filter products on the market are ordinary filter papers that can only filter the solid phase pollutants in the fuel, but the erosion of the filter paper by the fuel is rarely considered in the production design, which greatly shortens the life of the filter paper. service life
