Description
Technical Field
The invention relates to the technical field of filter materials, in particular to fuel filter paper and a preparation method thereof.
Background
At present, the material of the automotive engine oil filter paper is mainly paper containing a polymer coating, and the property of the polymer material determines the performance and the service life of the engine oil filter paper. The polymer coating for the prior engine oil filter paper in China is mainly acrylic resin, and the main defects of the engine oil filter paper are as follows: poor high temperature resistance, high moisture absorption and short service life. The polymer coating commonly used abroad is mainly phenolic resin, and the high temperature resistance of the engine oil filter paper product is good, the moisture absorption rate is low, and the service life is long; however, the phenolic resin is generally dissolved in an organic solvent, so that the preparation method has the advantages of large environmental pollution, low production safety coefficient and high production cost. The engine oil filter paper generally comprises a paper filter layer which is made of common wood pulp as a main component, and the common wood pulp fiber is thin and high in tightness, so that the manufactured engine oil filter paper has the defects of high tightness, low filtering efficiency, short service life and the like, and the paper engine oil filter paper also has poor solidification, water resistance and oil resistance. For example, chinese patent application publication No.: CN103993524a, no. 20 of 2014, entitled safe and environment-friendly fuel filter paper with good fire-resistant oil stability, is characterized in that the filter paper is prepared from the following raw materials in parts by weight: 50-54 parts of birch pulp, 52-57 parts of eucalyptus pulp, 3-4 parts of melamine formaldehyde resin, 0.3-0.5 part of sodium dodecyl benzene sulfonate, 1-2 parts of dried oleander leaves, 0.5-0.7 part of carrageenan, 0.3-0.4 part of linseed gum, 3-4 parts of quartz sand, 3-4 parts of activated carbon, 2-3 parts of glass fiber, 1-2 parts of ammonium chloride, 5-7 parts of polymethyl acrylate, 2-3 parts of dioctyl ester, 1-2 parts of auxiliary agent and a proper amount of water. The fuel filter paper prepared by the method has the advantages of high tightness, low filtering efficiency, short service life, low filtering precision and poor strength and toughness.
Disclosure of Invention
The invention provides the fuel filter paper with low tightness, high filtering efficiency, long service life, high filtering precision and good strength and toughness and the preparation method thereof, and aims to solve the defects of high tightness, low filtering efficiency, short service life, low filtering precision and poor strength and toughness of the fuel filter paper in the prior art
In order to achieve the above purpose, the invention adopts the following technical scheme:
the fuel filter paper comprises an outer high-permeability low-resistance support material and an inner filter paper base paper, wherein the support material comprises 10-20 parts of mercerized wood pulp in parts by weight; 20-40 parts of polyester resin; 10-20 parts of alkali-free glass fiber chopped filaments; 1-10 parts of polyester long fiber; the filter paper base paper comprises 40-80 parts of conifer bleached wood pulp in parts by weight; 0.2-8 parts of modified starch light calcium carbonate and 10-20 parts of alkali-free glass fiber chopped filaments; 1-15 parts of fibrous binder. The fuel filter paper prepared by the preparation method has the main performance indexes of 0.33g/cm < 2 >, the filtering efficiency of 96%, the service life of 12000 km, the filtering precision of less than 18 mu m, the bursting strength of more than or equal to 335Kpa and the tensile strength of 12KN.m.
Preferably, the tightness of the fuel filter paper is 0.3-0.5 g/cm < 2 >. The high tightness ensures that the paper has good tearing strength and tensile strength, ensures that the filter paper is not easy to break and lose efficacy in the filtering work, but the high tightness also easily reduces the filtering efficiency.
Preferably, the particle size of the alkali-free glass fiber chopped strands is not more than 100nm. The fiber with smaller particle size is favorable for interweaving and forming the fiber, so that the filter paper with good strength is obtained.
Preferably, the fuel filter paper has a basis weight of 210+ -10 g/square meter. Proper quantification is determined to balance the relationship between strength, filtration and rate, too high a quantification would result in too thick a substrate and reduced filtration rate, while too low a quantification would not meet the requirements for strength and filtration.
The preparation method of the fuel filter paper comprises the following steps:
a) Taking 10-20 parts of mercerized wood pulp, 20-40 parts of polyester resin, 10-20 parts of alkali-free glass fiber chopped filaments and 1-10 parts of polyester long fibers, pulping by a pulper, and pulping by a pulping machine, wherein the beating degree of pulping is 10+/-2 ℃;
b) Taking 40-80 parts of bleached softwood pulp, 0.2-8 parts of modified starch light calcium carbonate, 10-20 parts of alkali-free glass fiber chopped filaments and 1-15 parts of fibrous binder, fluffing by a fluffer, and carrying out online grinding by a double-disc pulping machine to obtain a pulp with the pulp degree of 18-22 DEG SR;
c) The sizing agent prepared in the step a) and the step b) is respectively made and pressed in an inclined wire paper machine or a flow-measuring cylinder paper machine to be molded, and a supporting material and filter paper base paper are respectively obtained;
d) And c) drying and curing the support material obtained in the step c) in a drying cylinder at 160 ℃ to obtain the target support material.
e) And c) drying and curing the filter paper base paper obtained in the step c) in a drying cylinder at 130 ℃ to obtain the target filter paper base paper.
