Abstract
The invention discloses a dust collector filter. The dust collector filter comprises a first polyester fiber layer and a second polyester fiber layer. Fibers in the first polyester fiber layer and fibers in the second polyester fiber layer are arranged in one direction. An included angle ranging from 33 degrees to 35 degrees is formed by the fibers in the first polyester fiber layer and the fibers in the second polyester fiber layers. The wind resistance and the filtering effect of the filter are changed by adjusting the angle between the polyester fibers; the filtering effect of the filter is further improved by additionally arranging a modifying layer; the self-adhesion strength of the modifying layer and the polyester fibers can be improved through hydroxyethyl acrylate blending modified polyurethane resin; the antibacterial effect of the filter can be improved through added silver oxide, and aluminum oxide and active carbon are used for changing the wind resistance of the filter.
Description
Technical field
The present invention relates to a kind of filtering material, be specifically related to a kind of dust catcher filter.
Background technology
As everyone knows, filtering material is the very common but very important parts of one in dust catcher, but for factors such as cost control, each manufacturer is reluctant to exert to develop more high-quality and efficient filtering material, but the filter of low cost in use for some time, easily blocks, cause dust catcher air draft not smooth, cause motor temperature to raise, thus have a strong impact on the life-span of motor; Or some filter exhaust effect can manage it, but not good to the filter effect of dust, cause fine dusts under the effect of motor, discharge dust catcher through filter, thus secondary pollution is caused to indoor environment, had a strong impact on the respiratory health of human body.
Summary of the invention
For the deficiencies in the prior art part, the object of the present invention is to provide the dust catcher filter that a kind of good filtration effect, windage are little.
Technical scheme of the present invention is summarized as follows:
A kind of dust catcher filter, it comprises the first layer of polyester fiber and the second layer of polyester fiber, wherein, filament in described first layer of polyester fiber and the second layer of polyester fiber is respectively in unidirectional array, and the filament in described first layer of polyester fiber and the filament in described second layer of polyester fiber are 33 ~ 35 ° of angles.
Preferably, described dust catcher filter, wherein, is also provided with modified layer between described first layer of polyester fiber and the second layer of polyester fiber, includes the polyurethane resin of the hydroxy-ethyl acrylate blending and modifying of 100 weight portions in described modified layer.
Preferably, described dust catcher filter, wherein, the number-average molecular weight of the polyurethane resin of described hydroxy-ethyl acrylate blending and modifying is 3000 ~ 3200g/mol.
Preferably, described dust catcher filter, wherein, in the polyurethane resin of described hydroxy-ethyl acrylate blending and modifying, the content of hydroxy-ethyl acrylate is 8 ~ 10wt%.
Preferably, described dust catcher filter, wherein, also includes the silver oxide of 2 ~ 3 weight portions in described modified layer.
Preferably, described dust catcher filter, wherein, also includes the aluminium oxide of 2 ~ 3 weight portions in described modified layer.
Preferably, described dust catcher filter, wherein, also includes the active carbon of 2 ~ 3 weight portions in described modified layer.
The invention has the beneficial effects as follows: windage and the filter effect of this case by regulating the angle between polyester fiber silk to carry out improved filter disc; By setting up modified layer, improve the filter effect of filter further; The polyurethane resin of hydroxy-ethyl acrylate blending and modifying also can increase the self-adhesion intensity of modified layer and polyester fiber silk; The silver oxide added can improve the antibacterial effect of filter, and aluminium oxide and active carbon are for improving the windage size of filter.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, can implement according to this with reference to description word to make those skilled in the art.
This case proposes the dust catcher filter of an embodiment, it comprises the first layer of polyester fiber and the second layer of polyester fiber, and wherein, the filament in the first layer of polyester fiber and the second layer of polyester fiber is respectively in unidirectional array, namely the filament in layer of polyester fiber is arranged in parallel, does not interlock each other; And the filament in the filament in the first layer of polyester fiber and the second layer of polyester fiber is 33 ~ 35 ° of angles.Research finds, two-layer filament at an angle after, the size of this angle can affect windage and the filter effect of filter, although adopt the orthogonal mode of two-layer filament more common in the prior art, but from windage and filter effect combination property, two-layer filament angle is 33 ~ 35 ° of filter effects that filter entirety can be made to obtain lower windage and Geng Gao.Polyester fiber can be preferably polyster fibre.
As another embodiment of this case, wherein, between the first layer of polyester fiber and the second layer of polyester fiber, be also provided with modified layer, in modified layer, include the polyurethane resin of the hydroxy-ethyl acrylate blending and modifying of 100 weight portions.The method of hydroxy-ethyl acrylate blending and modifying is before urethane monomer polymerization, is mixed in urethane monomer, carries out copolymerization subsequently by the hydroxyethyl acrylate monomers of corresponding addition.The introducing of hydroxy-ethyl acrylate has following improvements: 1) under the prerequisite not affecting filter windage, can reduce the hole of polyurethane inside, can filter out less particle to make modified layer; 2) make modified layer obtain outstanding tack, to ensure the adhesion strength of the first layer of polyester fiber and the second layer of polyester fiber, not cull, does not affect the windage of filter.
As the another embodiment of this case, wherein, the number-average molecular weight of the polyurethane resin of hydroxy-ethyl acrylate blending and modifying is 3000 ~ 3200g/mol.Research finds, after the number-average molecular weight of the polyurethane resin to hydroxy-ethyl acrylate blending and modifying limits, can obtain outstanding strainability.Therefore, its number-average molecular weight should be limited.
As the another embodiment of this case, wherein, in the polyurethane resin of hydroxy-ethyl acrylate blending and modifying, the content of hydroxy-ethyl acrylate is 8 ~ 10wt%.Research finds, in the polyurethane resin of modification, the content of hydroxy-ethyl acrylate also should be limited, and the number range departed from will affect filter effect and the windage size of filter.
As the another embodiment of this case, wherein, the silver oxide of 2 ~ 3 weight portions is also included in modified layer.The effect of silver oxide has 2 points: the fungistatic effect 1) increasing filter; 2) reduce the resilience dynamics of wind, the air-flow in dust catcher in control of dust cabin is stablized more smooth-going.But the addition of silver oxide should be restricted, if addition is less than 2 weight portions, then cannot reach antibacterial, the effect of decreasing rebound dynamics, if be greater than 3 weight portions, then can increase the windage size of filter.
As the another embodiment of this case, wherein, the aluminium oxide of 2 ~ 3 weight portions is also included in modified layer.Aluminium oxide is Woelm Alumina, and its loose structure had effectively can reduce the windage of filter, and therefore, the addition of aluminium oxide should be limited.
As the another embodiment of this case, wherein, the active carbon of 2 ~ 3 weight portions is also included in modified layer.Active carbon can work in coordination with generation effect with aluminium oxide, after active carbon is combined with aluminium oxide, the windage of filter can be reduced further, improve filter effect simultaneously, in addition, the modified layer formed after being combined with the polyurethane resin of hydroxy-ethyl acrylate blending and modifying by active carbon, aluminium oxide effectively can reduce the wind-dryness of dust catcher operationally in control of dust cabin, and therefore, the addition of active carbon should be limited.
