Abstract

The invention relates to the technical field of filtering materials, and discloses fuel oil filter paper which comprises a high-permeability low-resistance supporting material on the outer side and filter paper body paper on the inner side. The supporting material comprises, by weight, 10-20 parts of mercerized wood pulp; 20-40 parts of polyester resin; 10-20 parts of alkali-free glass fiber chopped strands; and 1-10 parts of polyester long fiber. The filter paper body paper comprises the following components in parts by weight: 40-80 parts of softwood bleached wood pulp; 0.2-8 parts of modified starch light fat calcium carbonate, 10-20 parts of alkali-free glass fiber chopped strands, and 1-15 parts of fibrous binding element. The fuel oil filter paper and the preparation method thereof disclosed by the invention have the beneficial effects of low tightness, high filtering efficiency, long service life, high filtering precision, good strength and toughness and convenience and safety in use.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a fuel filter paper and a preparation method thereof. Background technique [0002] At present, the material of automobile oil filter paper is mainly paper with polymer coating, and the properties of polymer materials determine the performance and service life of oil filter paper. The existing domestic polymer coatings for oil filter paper are mainly acrylic resins. The main disadvantages of this type of oil filter paper products are: poor high temperature resistance, high moisture absorption rate and short service life. The polymer coating commonly used abroad is mainly phenolic resin. This kind of oil filter paper product has good high temperature resistance, low moisture absorption rate and long service life; The pollution is large, the production safety factor is low, and the production cost is high. The oil filter paper usually includes a paper filter layer made o...
