Abstract
The utility model relates to filter paper, and aims to provide bypath filter paper applied in an oil cleaner. The bypath filter paper comprises a paper filter bed, and a resin bed uniformly coated on the surface of the filter bed. The resin bed is a compound water-soluble resin layer of phenolic aldehyde and polyacrylate. The bypath filter paper provided by the utility model has that advantages of high temperature resistance, environment protection, safety, low cost, and high water and oil resistance.
Description
Technical field
The utility model relates to a kind of filter paper, particularly a kind of bypass filter paper of using in oil filter.
Background technology
Bypass filter paper is the important composition parts in the oil filter, is related to the overall performance of oil filter.It is the filter course a kind of made of paper that Main Ingredients and Appearance is made that bypass filter paper generally includes with common wood pulp, because the normal wood pulp fibres is thin, tightness is high, therefore made bypass filter paper ubiquity shortcomings such as tightness height, filter efficiency is low, the life-span is short, and bypass filter paper made of paper also ubiquity resistance to water and oil resistivity is poor, characteristics such as not environmental protection of non-refractory.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of oil resistant water resistant to elevated temperatures bypass filter paper.
In order to address the above problem, the utility model is by being achieved as technical scheme under the environmental protection:
A kind of bypass filter paper comprises filter course made of paper, and the surface of described filter course also evenly is being coated with one deck resin bed, and described resin bed is the compound water-soluble resin layer of phenolic aldehyde and polyacrylate.
Compared with prior art, the beneficial effects of the utility model are:
Because the water-soluble resin layer that adopts phenolic aldehyde and polyacrylate to be composited on the surface of filter course made of paper, the not only environmental protection but also high temperature resistant of these resins, therefore bypass filter paper of the present utility model has good temperature resistance, and Environmental Safety, cost is low, has excellent water tolerance and oil resistivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In conjunction with the accompanying drawings, below the utility model is described in further detail.
Bypass filter paper of the present utility model comprises filter course made of paper 1, and the surface of described filter course 1 also evenly is being coated with one deck resin bed 2, and resin bed 2 is the compound water-soluble resin layer of phenolic aldehyde and polyacrylate.Applying glue concentration 10%-25% during coating, resin added 15%-25%.
The measurement result of bypass filter paper of the present utility model sees Table one:
(quantitative mensuration adopts GB/T451.2-2002 paper and the quantitative determination method of cardboard; The mensuration of bursting strength adopts the mensuration of GB/T454-2002 paper bursting strength.)
Table one: the technical indicator of bypass filter paper
| Project | Index |
| Quantitatively, g/m 2 | 270±8 |
| Thickness, mm 〉= | 0.55 |
| Air permeability (Δ P=127pa), L/m 2·S≥ | 10 |
| The maximum diameter of hole, μ m | 30 |
| Bursting strength, kpa 〉= | 500 |
| Average pore size, μ m | 20 |
| Delivery moisture content, % | 7.0±2.0 |
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
