Background technology
Nuclear pore membrane is subject to market and welcomes as false proof and filtration applications, and especially for false proof, it can not be copied and be identified by the consumer easily, and so the especially selection of high-end customer is market demand rapid growth.The production process of nuclear pore membrane is: go bombardment (irradiation) polymer material film by the fission particle of nuclear reactor generation or the high energy particle of tandem heavy ion avcceleration generation, damage its strand, the part that is damaged strand can form and be different from raw-material soda acid characteristic, place the alkali lye (perhaps acid solution) can dissolved (etching) macromolecular chain that is damaged after the bombardment of this irradiation, thus form density be every square centimeter hundreds thousand of be micron-sized microporous barrier to tens million of individual, apertures.
At present aborning; for guaranteeing that micropore appears in assigned address; and micropore does not appear in some place; and be not subjected to the erosion of alkali lye (perhaps acid solution); need to make in process of production a kind of safeguard structure for the nuclear pore membrane production process; namely at the polymer material film 11 coating overcoats 12 (be called imaging) of predose to not needing the micropore part; and because protective coating is water white transparency; so; can't two-sided contraposition be coated with; can only be coated with protective coating, another side complex protection material layer 13, i.e. single face etching by single face.Because etching process is comparatively slow, walks the film per minute and only be 1-2 rice.So the production efficiency under this kind safeguard structure is low, can not meet the need of market.
Summary of the invention
The object of the present invention is to provide a kind of safeguard structure for the nuclear pore membrane production process that can improve nuclear pore membrane production efficiency.
A kind of safeguard structure for the nuclear pore membrane production process of the present invention comprises first rete that is used to form the first nuclear pore membrane; thinking in this first rete one side does not need the position of micropore to be coated with the first overcoat; another side compound protective film at this first rete; it is characterized in that: the another side with respect to the first rete composite surface on protective film is compounded with second rete that is used to form the second nuclear pore membrane, and thinking with respect to the another side of protective film composite surface at this second rete does not need the position of micropore to be coated with the second overcoat.
Further, described the first rete, the second rete are to be combined with protective film by binder behind the coating release layer.
Further, described the first rete, the second rete and protective film are the PET film.
Further, described the first rete, the second rete uniform thickness
Further, the thickness of described the first rete, the second rete and protective film is respectively 15 microns, 15 microns and 12 microns.
One of a kind of nuclear pore membrane production method of using safeguard structure of the present invention is characterized in that step is as follows:
(1) be coated with overcoat: thinking in the one side of the first rete and the second rete does not need the position of micropore to be coated with respectively overcoat, oven dry.
(2) coating release layer and binder: the one side that is not coated with overcoat at the first rete and the second rete is coated with respectively release layer and binder successively.
(3) twice compound: with the two sides of protective film respectively with the first and second retes on release layer bind by binder.
(4) irradiation: adjust irradiation energy intensity, reach the intensity that can penetrate respectively the first and second retes, with each irradiation of safeguard structure two sides after compound once.
(5) etching: with film etching in alkali lye or acid solution of safeguard structure.
(6) peel off: the first rete and the second rete are peeled off out, namely obtain two-layer microporous barrier.
The employed overcoat of this method adopts antiacid alkaline etching and anti-irradiation material to make, and is metal or the nonmetallic materials that are added with the high energy particle energy of decaying in antiacid alkaline etching material.
Two of a kind of nuclear pore membrane production method of using safeguard structure of the present invention is characterized in that step is as follows:
(1) be coated with overcoat: thinking in the one side of the first rete and the second rete does not need the position of micropore to be coated with respectively overcoat, oven dry, and rolling is for subsequent use.
(2) coating release layer and binder: the one side that is not coated with overcoat at the first rete and the second rete is coated with respectively release layer and binder successively.
(3) twice compound: with the two sides of protective film respectively with the first and second retes on release layer bind by binder.
(4) irradiation: adjust irradiation energy intensity, reach the intensity that can penetrate whole safeguard structure thickness, irradiation once.
(5) etching: with film etching in alkali lye or acid solution of safeguard structure.
(6) peel off: the first rete and the second rete are peeled off out, namely obtain two-layer microporous barrier.
The employed overcoat of this method adopts antiacid alkaline etching material.
The invention has the advantages that:
(1) using method one under safeguard structure of the present invention realizes that through twice irradiation an etching can be produced two-layer effective microporous barrier, so that etching speed doubles, operation reduces one times, and saves half diaphragm;
(2) using method two under safeguard structure of the present invention then realizes irradiation one time, and an etching can be produced two-layer effective microporous barrier, so that etching speed improves 1 times, operation reduces one times, and saves half diaphragm.Whole new technology speed of production is conventional method 4-5 times.
