Abstract
The invention discloses a membrane mulching and filtering material which comprises a spun-bonding nonwoven material and a layer of polymer microporous membrane covered on the surface of the spun-bonding nonwoven. The material has high collection efficiency and excellent mechanical properties and is easy to remove dust.
Description
Technical field
The present invention relates to a kind of nonwoven coated filter material product that is used for the air filtration aspect.
Background technology
PET long fiber nonwoven fabrics and high molecular weight ptfe film are laminated with filtrate, are the novel filter materials of developing in recent years, are mainly used in field of air filtration.It has given full play to PET nonwoven fabric of long fibers and polytetrafluoroethylene (PTFE) advantage separately, has remedied deficiency separately, and acting in conjunction has produced the good comprehensive effect.
Name is called the Chinese patent (application number is 03129430.8) of " filtering material of polytetrafluoroethylene (PTFE) composite membrane ", disclosed the filtering material of a kind of air filtration industry with polytetrafluoroethylcomposite composite film, it is composited by glass fibre, two kinds of materials of polytetrafluoroethylene (PTFE), wherein glass fibre is a base cloth, polytetrafluoroethylene (PTFE) is a skin covering of the surface, by bonding agent both bondings is formed.Its bonding agent is any one a macromolecular compound in polysulfones, nylon N6, the polyvinylidene fluoride.This fiberglass overlay film filter material is because resistant glass fiber bending property is poor, therefore when being processed into fold formula air cleaner, there is very big problem, filtering material fractures easily, therefore need a kind of filtering material of anti-bending to make base cloth, PET nonwoven fabric of long fibers covering material provided by the present invention has so just solved the relatively poor problem of resistant glass fiber bending property.
Summary of the invention
The object of the present invention is to provide a kind of arresting efficiency height, deashing is easy, the coated filter material of mechanical performance excellence.
Technical solution of the present invention is:
A kind of coated filter material comprises viscose non-woven material, it is characterized in that: in spunbonded nonwoven filter cloth surface coverage one deck high molecule micropore film is arranged.
The fiber that constitutes the spunbonded nonwoven filter cloth is a sheath-core bicomponent fibre, and its mediopellis fusing point is low, helps the bonding of fibre web more, and sandwich layer fusing point height can increase the rigidity of this material, and the brute force of viscose non-woven material is guaranteed.Finished product after this bicomponent fibre is processed the fold of this filtering material has also played the effect that increases its anti-bending rigidity, make it under the condition of bigger filtration wind speed, also keep original fold morphology, be unlikely to be out of shape and cause that filter area diminishes and the consequence of material cracky because of distortion forms.This filtering material can stand the filtration of big wind speed more from this point, is better than other filtering material.The low-melting fiber of described cortex is for the sandwich layer fiber.
The thickness of high molecule micropore film is between 5-150 μ m, and porosity is more than 95%.Such film thickness and porosity have improved the venting quality of this filtering material, have reduced filtration resistance, have reached the purpose that cuts down the consumption of energy.This thin layer can also play the effect of initial dust layer, guarantees that better dust can not enter the viscose non-woven material layer easily.Deashing after this in addition macromolecule membrane helps filtering more, because the low-friction coefficient that PTFE itself has, so dust is more prone to remove.Film thickness through preferred 20～100 μ m of overtesting.
The grammes per square metre scope of spunbonded nonwoven filter cloth is 10～300g/m
2Guaranteed intensity filter and dust containing capacity, the rigidity of filtering material and anti-bending performance also are improved, and make the strainability of this filtering material obtain further raising.
The high molecule micropore film is a poly tetrafluoroethylene, has very high peel strength, and cohesive is very excellent, makes this filtering material can not break away from the viscose non-woven material layer easily in filtration and deashing process.
Described coated filter material venting quality is 0.5～30cc/cm
2Sec, tensile break strength vertically are 1200～1500N/5cm, laterally are 650～1000N/5cm.Guaranteed its impact-resistant ability when filtration velocity is very big like this, and on-deformable characteristics.
The employed raw material of the spunbond nonwoven layers of this filtering material is a polypropylene, raw materials such as polyester, and be the fiber of bicomponent sheath cored structure, the core-skin layer all adopts PP or PET, but the fusing point difference of core-skin layer, perhaps cortex is selected PP for use, and sandwich layer is selected PET for use, guarantees its bond properties and anti-buckling strength.
Arresting efficiency height of the present invention, deashing is easy, the mechanical performance excellence.
The invention will be further described below in conjunction with embodiment.
The specific embodiment:
Embodiment: with the 260g/m among the present invention
2Spunbonded nonwoven filter cloth (raw material is polyester or polypropylene) be laminated with one deck polytetrafluoroethylene (PTFE) film, the fiber that constitutes the spunbonded nonwoven filter cloth is a sheath-core bicomponent fibre, its mediopellis fiber fusing point is lower than the sandwich layer fiber).
The thickness of high molecule micropore film is that porosity is more than 95% between the 5-150 μ m.
Its performance parameter is as follows:
