Abstract
The utility model belongs to the technical field of filter paper and discloses air filter paper suitable for vehicles in moist environment. The technique scheme of the filter paper is characterized in that a wood fiber base layer for supporting and a superficial layer formed by polyester fiber with hydrophobic performance form a filer paper blank by absorbing direct composite felt, and the filer paper is formed by dip-coating resins on the filter paper blank. Based on the fact that the paper is formed by coating resins on the wood fiber base layer and the polyester fiber (terylene) superficial layer and that the polyester fiber layer has great hydrophobic performance with the water absorption below 1%, when a filter made by utilizing the filter paper is used in moist areas, water molecules are firstly stopped by the polyester fiber layer to enable the wood fiber base layer compounded with the polyester fiber layer to maintain a dry state, thereby keeping porosity and filtering efficiency of the filter paper unchanging and prolonging service life of the filter paper.
Description
Technical field
The utility model belongs to the filter paper technical field, relates in particular to a kind of wet environment automobile air filter paper that is applicable to.
Background technology
Being used in the air paper in the car combustion engine, is the important composition that constitutes air filter, and is determining the performance of air filter.What at present, be used in that the filter paper of the air filter under the rainy wet environment condition uses is that two sides dip-coating resin bed at single xylon layer constitutes.As China Patent No. is to be that the disclosed a kind of air paper of utility model patent of CN201158784Y, this filter paper evenly are being coated with one deck resin bed by the surface at the papery filter course and are constituting ZL200820081953.5, Granted publication number.Although the air paper of this structure is because surperficial being coated with the resin bed of one deck by polyacrylate, can reduce the water absorption rate that constitutes the papery filter course makes its distortion little, but when this air paper uses in the high area of rainy humidity, being coated with one deck polyacrylate layer is difficult to stop moist moisture to enter the papery filter course, and can taking place after the papery filter course moisture absorption, profit rises, cause the aperture and the porosity of filter paper to reduce, cause the problem that the cleaner resistance increases and power of vehicle reduces.In a word, the air filter of this structure still exists short problem in service life.
The utility model content
What the purpose of this utility model just provided a kind of long service life is applicable to wet environment automobile air filter paper.
In order to realize the utility model purpose, the technical scheme that is adopted is:
A kind of wet environment automobile air filter paper that is applicable to forms the filter paper blank by passive wood fibre basic unit with by the superficial layer that the polyester fiber with hydrophobic property forms by the direct composite felt bundle of absorption, and the dip-coating resin constitutes on described filter paper blank.
Wherein, the gram volume of described filter paper is 120-140 gram/square centimeters, and the gram volume of wherein said wood fibre basic unit is 70-85 gram/square centimeters.
Provided by the utility modelly be applicable to wet environment automobile air filter paper and preparation method thereof compared with prior art, have the following advantages: be applicable to that wet environment automobile air filter paper is directly to be combined into the filter paper blank by wood fibre basic unit with by polyester fiber (terylene) superficial layer by adsorbing owing to constitute this, and constitute at the attached resin bed of the surperficial Tu of this blank and to form, water absorption rate based on the layer of polyester fiber that constitutes superficial layer has extremely strong hydrophobicity below 1%, therefore the car combustion engine cleaner that utilizes this air paper preparation is when having a humid climate the area use, can make that at first hydrone is stoped by layer of polyester fiber, the state that the feasible wood fibre basic unit that is combined with each other with it can keep dry basically, thereby can keep the porosity of this air paper and filter efficiency constant substantially, prolong the service life of filter paper.
Description of drawings
Fig. 1 is the structural representation that is applicable to wet environment automobile air filter paper;
Fig. 2 is the schematic flow sheet of the above-mentioned car combustion engine air paper of preparation.
The specific embodiment
Below in conjunction with accompanying drawing a kind of structure of wet environment automobile air filter paper that is applicable to that the utility model provides is described in further details.
As shown in Figure 1, a kind of structural representation that is applicable to wet environment automobile air filter paper that provides for the utility model.The structure that constitutes this air paper comprises the superficial layer 2 that forms by passive wood fibre basic unit 1 with by polyester fiber (polyster fibre) and through forming resin bed 3,4 formations behind the dip-coating resin.Wherein, directly be compounded to form the filter paper blank by wood fibre basic unit with by the superficial layer that polyester fiber forms, the gram volume that constitutes wood fibre basic unit of this filter paper blank is 70-85 gram/square centimeters, and the polyester fibre surface layer is 50-55 gram/square centimeters.
Be illustrated in figure 2 as the process flow diagram of the above-mentioned car combustion engine air paper of preparation, promptly this flow process comprises, simultaneously by the slurry net 5 of fiber pulp by the actuating unit drive, 6 prepare wet xylon basic unit 7 and polyester fibre surface layer 8, then two fibre layers is superimposed and enters vacuum chamber 9, by the moisture in the above-mentioned two-layer wet fiber layer of vacuum device 13 extractions, make two fibre layers form one deck structure 10 that mutual felt is pricked, enter drying chamber 11 oven dry then and form fiber filter paper blanks 12, with the filter paper blank by dip-coating resin operation 14, second baking operation 15 and roll 16 can prepare that patent application of the present invention provides can be applicable to wet environment automobile air filter paper.
In the structure that constitutes above-mentioned car combustion engine cleaner filter paper, the xylon that the xylon that constitutes basic unit generally adopts fiber is long and wide, intensity is better, cellulosic degree of polymerization is higher pine or leaf wood to make, by the many micropores of short texture and the air permeability height of the formed basic unit of xylon, have the characteristics of filter efficiency height and dust containing capacity; The superficial layer 2 that forms by the thinner polyester fiber of diameter (also being polyster fibre), when malaria is entered in the filter paper when entering internal combustion engine through basic unit again by superficial layer, at first the superficial layer that is formed by polyester fiber (also being polyster fibre) stops entering of hydrone, effectively avoid the basic unit that constitutes by wood fibre profit to take place and rise by the problem that causes porosity to reduce because of entering of moisture.The polyester fibre surface layer is realized filtration to particle effectively having improved its filter efficiency with loose microporous basic unit.
On the filter paper blank resin of dip-coating be phenolic resins, acrylic resin or/and polyvinyl acetate is coated in these resin adhesive liquid on the filter paper blank, can infiltrate hangs on the fiber in inside; The drying operation, make surface and certain depth layer of filter paper form the very resin glue-line of holder effect, this resin bed can also effectively improve the physical strength and the structural strength thereof of filter material, can satisfy the instructions for use of filter material, when being used to filter, can keep good strainability, its structure is not caved under pressure reduction, and maintain the pre-existent pore of filter material, prevent the fiber of filter material in the filter process and other tissue phenomenon that is moved.In addition, dipping also can make filter material have higher anti-chemistry and solvent resistance energy.
