Abstract
The invention discloses a method for controlling a thickness customization aperture porous membrane, which comprises the following steps: polyethylene with millions of molecular weight and an organic liquid containing a plasticizer and organic alcohol are mixed, and then a mixer is extruded by a first extruder; polyethylene with more than 100 thousands of molecular weight and organic liquid containing the plasticizer are mixed, and the mixer is extruded by a second extruder; and polyethylene with more than 4-50 thousands of molecular weight and mineral oil with 10% of organic alcohol are mixed, and the mixer is extruded by a third extruder. According to the control method, the porous base materials with required aperture uniformity and aperture distribution are produced, the multilayer film is prepared by a film blowing head with multiple layers, each layer of the film is an aperture structure produced by the individual extruder according to an unique formula, the aperture structure has a defined porosity and aperture size, the production cost is reduced, and the work efficiency is increased.
Description
Technical field
The invention belongs to perforated membrane and manufacture field, relate in particular to the control method of a kind of thickness customization aperture perforated membrane.
Background technology
Thermally induced phase separation is more than the fusing point of polymer, and polymer is dissolved in to higher boiling, in the solvent of low volatility, forms homogeneous phase solution, then cooling down, and in cooling procedure, system can be separated.Application thermic phase detachment technique is prepared the method for porous substrate, and an aspect is the pore structure of control surface and the pore structure in cross section, on the other hand by what control pore size and porosity.In cooling procedure, greatly affected the thickness of whole base material and the uniformity in aperture, and this kind of cooling effect is difficult to control the Changeization of the base material thickness that whole base material thickness and aperture inhomogeneities cause more.
Summary of the invention
The object of the invention is to utilize the control method of a kind of thickness customization aperture perforated membrane, be intended to solve existing preparation in porous substrate cooling procedure, greatly affected the thickness of whole base material and the uniformity in aperture, this cooling effect is difficult to control the problem of the increase of the base material thickness that whole base material thickness and aperture inhomogeneities cause more.
The control method that the object of the present invention is to provide a kind of thickness customization aperture perforated membrane, described control method comprises: the polyethylene of Number 1,000,000 molecular weight and the organic liquid that contains plasticizer and Organic Alcohol mix, and are extruded by first extruder; The polyethylene of more than 100 ten thousand molecular weight mixes with the organic liquid that comprises plasticizer, is extruded by second extruder; The polyethylene of many hundred million molecular weight of 4-50 and the mineral oil of 10% Organic Alcohol, extruded by the 3rd extruder.
Further described perforated membrane is one and has 3 kinds of different discrete porositys and the film in aperture in whole base material thickness direction (Z direction).
The control method of thickness customization of the present invention aperture perforated membrane, the method technical matters is simple, easy to operate, produces the porous substrate of the required aperture uniformity and pore-size distribution, has improved operating efficiency, has reduced production cost, has good using value.
Accompanying drawing explanation
Fig. 1 is the flow chart of the control method of thickness customization provided by the invention aperture perforated membrane.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The embodiment of the present invention provides the control method of a kind of thickness customization aperture perforated membrane, and this control method comprises: the polyethylene of Number ten thousand molecular weight and the organic liquid that contains plasticizer and Organic Alcohol mix, and are extruded by first extruder; The polyethylene of more than 100 ten thousand molecular weight mixes with the organic liquid that comprises plasticizer, is extruded by second extruder; The polyethylene of many hundred million molecular weight of 4-50 and the mineral oil of 10% Organic Alcohol, extruded by the 3rd extruder.
As a prioritization scheme of the embodiment of the present invention, perforated membrane is one and has 3 kinds of different discrete porositys and the film in aperture in whole base material thickness direction (Z direction).
Referring to accompanying drawing 1, the control method of being prepared by the present invention to thickness customization aperture perforated membrane is described in further detail.
As shown in Figure 1, the perforated membrane control method in a kind of thickness customization aperture of this programme invention, first the polyethylene of Number ten thousand molecular weight and the organic liquid that contains plasticizer and Organic Alcohol are mixed, by extruding as the double screw extruder of ground floor blown-film die, then, the polyethylene of more than 100 ten thousand molecular weight mixes with the organic liquid that comprises plasticizer, is extruded by second double screw extruder as second layer blown-film die; The polyethylene of many hundred million molecular weight of 4-50 and the mineral oil of 10% Organic Alcohol, extruded by the 3rd double screw extruder as the 3rd layer of blown-film die, finally, when film from blown-film die out, it has 3 layer scattering layers, is one and has 3 kinds of different discrete porositys and the film in aperture in whole base material thickness direction (Z direction).
The control method of thickness customization of the present invention aperture perforated membrane, this control method comprises: the Number very much polyethylene of strength mixes with the organic liquid that contains plasticizer and Organic Alcohol, is extruded by first extruder; The polyethylene of more than 100 ten thousand molecular weight mixes with the organic liquid that comprises plasticizer, is extruded by second extruder; The polyethylene of many hundred million molecular weight of 4-50 and the mineral oil of 10% Organic Alcohol, extruded by the 3rd extruder.The control method of thickness customization of the present invention aperture perforated membrane, the method technical matters is simple, easy to operate, produces the porous substrate of the required aperture uniformity and pore-size distribution, has improved operating efficiency, has reduced production cost, has good using value.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
