Description
Technical field
The invention belongs to antenna production technical field, be specifically related to a kind of production method of RFID paper substrate aluminum antenna.
Background technology
The English full name of RFID is Radio Frequency Identification.RFID radio-frequency (RF) identification is exactly simply a kind of contactless automatic identification technology, and it automatically identifies destination object by radiofrequency signal and obtains related data, and whole identification work need not manual intervention, can work in various adverse circumstances.RFID technique can identify swiftly passing object and single very concrete object, and can identify multiple label simultaneously.Because it adopts radio frequency, data can be read through exterior material, and can identify multiple object simultaneously, so more convenient and quicker, except these, also has a maximum feature to be that information memory capacity is very large.The range of application of future electronic label will be very widely.
Existing label antenna production method is normally the aluminium etching antenna of base material with PET film, and PET film is the PETG macromolecular material being not easy to degrade, and easily gives environment after application; In addition, such antenna adopts chemical method for etching substantially, also to environment and destruction.
In existing label antenna production technology, except mode of printing can carry out except antenna production on the disposable materials such as paper, other the mode of production all can not realize the object of disposable antenna production.
Winding method is by the certain number of turn of metal wire (normally copper cash) coiling of certain fineness, completes the making of antenna, the antenna attachment base material that this mode is not fixed, and production cost is higher, and production efficiency is lower; Etching method and galvanoplastic can not make antenna on disposable material, and these two kinds of mode of production costs are higher in addition, there is environmental pollution.Mode of printing mainly relies on electrically conductive ink, print thickness and the concentration of electrically conductive ink are wayward, easily cause label antenna unstable properties, and printed antenna is easily impaired simultaneously, cause and read and write unsuccessfully, friction resistant poor performance, the antenna of electrically conductive ink printing, the stability of quality is bad, particularly in flexible label, antenna easily damages, and causes tag defeat, and cost is also relatively high; Plated antenna step is complicated, and the production cycle is longer, and waste liquid flushing liquor easily causes environmental pollution, difficult popularization.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of production method of RFID paper substrate aluminum antenna, reduce the cost of manufacture of RFID, realize the disposable antenna of paper and produce, the antenna thickness of preparation evenly, friction resistant ability by force, not fragile, Performance comparision stablizes.
The production method of RFID paper substrate aluminum antenna of the present invention, comprises the following steps:
(1) take paper as base material, preliminary treatment is carried out to the surface of base material, form film paper;
(2) on film paper, be coated with separator, this separator is the mixed solution of EVA resin, tackifier, toluene and ethyl acetate;
(3) film paper and the aluminium foil layer of coated separator step (2) obtained adopt polyurethane composite gel to be coated with on dry compound machine, and compacting, obtains paperback aluminum foil;
(4) paperback aluminum foil is installed on die-cutting machine, according to design shape and the size of antenna, cross cutting is carried out to paperback aluminum foil, and peel off unnecessary aluminium foil, obtain antenna.
Wherein: in step (1), preliminary treatment is: on film machine, adopt polyethylene to carry out heat seeling coating to the surface of base material, do the process of single or double film; Under normal circumstances, the surface irregularity of paper, can improve the smoothness of base material by the mode of film; Film material is preferably the one in polythene PE, polyvinylchloride or BOPP Biaxially oriented polypropylene.
Base material is preferably art paper or offset paper.
Separator is EVA, tackifier, toluene, ethyl acetate is 23-30:2-5:45-55:22-28 mixing in mass ratio, is preferably 23:3.5:52:26 mixing in mass ratio.It is in order to after next step die-cut antenna that leaching membrane layer is coated with separator, can complete the peeling off by unnecessary aluminium foil, and during stripping, aluminium foil layer, polyurethane composite gel are stripped together with separator.The aluminium foil stripped down can be recycled.
Tackifier are one or both in C5 tackifier or C9 tackifier.
The design of antenna pattern and size adopts existing technique, the operating frequency clearly adopted, the dielectric constant of base material, the technical parameters such as the reading/writing distance of requirement, calculates the resistance, inductance etc. of antenna, designs the shape and size of antenna; According to Antenna Design drawing, processing mould cutter, if output is large, can makes circular pressing and cutting cutter, if production quantity is few, can make flat-press flat-die cutter.
Adopt polyurethane composite gel coating for adopting polyurethane composite gel coating under vacuum in step (3).
During (4) step cross cutting, with complete incision aluminium foil, and not injure paper substrate be debug standard.In step (4), die-cut is platen or circular pressing and cutting mode.
In sum, the present invention has the following advantages:
(1) adopt paper as the base material of antenna, greatly can reduce the cost of manufacture of RFID, the electronic tag simultaneously used for designing and developing disposable anti-false provides the design of a kind of brand-new inlay inlay;
(2) adopt the disposable materials such as paper as the base material of antenna, realize the disposable antenna of paper and produce, realize electronic tag not transferability, can be applicable to the false proof industry of logistics;
(3) adopt paper material to be convenient to printing, realize the double-point information safety guarantee of visual information and electronic labeling information;
(4) the present invention adopts dry type clad aluminum foil, and the antenna thickness of preparation is even, and the deviation of product thickness is within 5%, 90 ° of peel strengths of aluminium foil and leaching membrane paper are greater than 0.2KN/m, and friction resistant ability is strong, not fragile, can not be wrinkling in volume to volume process of manufacture, stable performance.
(5) material therefor of the present invention is environment friendly and pollution-free, and production method of the present invention is a kind of technology of very clean production antenna.
