A kind of imitative metal coating goods, comprise following processing step:
The first step, carries out electrostatic precipitation process on plastic basis material surface;
Second step, spray painting UV primer;
3rd step, carries out vacuum plating: at 4.0-7.0x10 after UV solidifying priming paint
-2under the vacuum tightness of pa, by indium stannum alloy fusing evaporation, deposit at substrate surface, form the alloy firm of one deck dense uniform, the thickness of this film is 80-100nm; Wherein, in described indium stannum alloy, the content of indium is 10.0% ~ 100%;
4th step, coatings sprays UV finish paint;
5th step, after UV topcoating cures, pastes wireless radio frequency identification mark.
As further preferred embodiment, before carrying out spray painting UV primer, prebake process is carried out to base material.
The present invention utilizes the imitative metal coating goods of RFID anti-interference coating process preparation, as shown in Figure 1, comprise plastic basis material 1, UV undercoat 2, metal alloy coating 3, UV top coat layer 4 and wireless radio frequency identification mark 5, layer of metal alloy layer 3 is plated by the mode of evaporation at the upper surface of plastic basis material 1, described UV undercoat 2 is located between plastic basis material 1 and metal alloy coating 3, namely, first brush one deck UV prime coat on the surface of plastic basis material 1, and then layer of metal alloy layer is established on UV prime coat.Establish UV top coat layer 4 at the upper surface of metal alloy coating 3, wireless radio frequency identification mark 5 is located at UV top coat layer 4 upper surface by radium-shine mode.
The metal alloy of described metal alloy coating is metal alloy is indium stannum alloy or pure indium, and it selects according to as follows:
Produce on the basis of interference principle at metal pair RFID, understand the characteristic of various metal, according to alloy part properties of materials, with the alloy material of special proportioning as Coating Materials, the metal alloy coating obtained by vacuum vapor plating, is disturbed enough little to the normal read-write of RFID or does not produce interference effect completely.
Following table one is the essential property of several conventional ornamental plating filmed metals material:
Under normal circumstances, the Coating Materials that plastic vacuum coating uses is generally based on metallic aluminium, but aluminium metal coating produces interference effect to RFID read-write.Therefore, although aluminizing is the most frequently used decoration technique, can not select here.Nickel fusing point is too high, and expensive; Chromium fusing point is too high, but firmly, good decorating effect; Tin fusing point is too low, uses as vacuum plating Coating Materials seldom separately.
Therefore, after considering, draw different metal advantage separately, by alloy technology, using indium stannum alloy or pure phosphide material as the jamproof decorative plastic technologic material of RFID label tag.The magnetic conduction function utilizing part metals excellent, because magnetic permeability is high, loss is little, for magnetic line of force provides effective approach, weakens eddy current interference effect, reaches RFID and identify the object that can normally read.
Technical process of the present invention is:
Substrate surface electrostatic precipitation process → spray painting UV primer → UV solidification → vacuum plating → spraying UV finish paint → UV solidification → finished product.
The first step, spray painting UV primer coating:
For ABS plastic, electrostatic precipitation will be carried out in ABS substrate surface before spray painting UV primer, and object is that the impurity such as dust surface of plastic products adhered to are removed, and ensures that substrate surface is totally dustless.If if necessary prebake can be carried out to material, one is remove moisture a large amount of in material, second can eliminate internal stress, is heated to slightly maintain the regular hour lower than heat-drawn wire by plastic part, make molecular rearrangement in product, the object reducing or eliminating internal stress can be reached.
Spray painting UV primer coating, the covering with paint object of carrying out base paint is:
1. plastic substrate and film adhesion poor, the coefficient of expansion differs an order of magnitude, and film easily breaks;
2. the direct plated film of frosting, the gloss of rete is generally very poor, lacks metal sense;
3. contain large quantity of moisture, residual solvent, softening agent, monomer and oligomerization material in plastics, affect the vacuum plating speed of evacuation, after spray primer, these volatile components can be closed, greatly improve pumping speed.Low coating levelling will be got well, smooth, coating uniform, without long-pending oil or drain spray phenomenon.
Second step, vacuum plating:
Under certain vacuum condition, by metal alloy wires fusing evaporation, deposit on plastic basis material surface, form the alloy firm of one deck dense uniform, make plastic basis material surface have metal-like.
3rd step, spraying UV external coating (EC), the covering with paint object of carrying out external coating (EC) is:
1. improve surface hardness, strengthen wear resistance;
2. improve antiseptic power, strengthen weather resistance;
3. improve surface smoothness, strengthen metal sense and ornamental; External coating (EC) requires smooth, coating uniform, without long-pending oil or drain spray phenomenon.
embodiment 1: adopt indium stannum alloy as Coating Materials, indium tin ratio is 1:9.
Adopt the mode of vacuum plating, by indium stannum alloy evaporation in surface of plastic products, the coated film plastic product surface made by above technique sticks RFID label tag, and when chip frequency is 930MHz, readable distance is 28cm.The thickness of evaporation coating is about 90nm each time, and indium stannum alloy coatings thickness can affect the detection operating range of rfid interrogator, and coatings is thicker, and the detectable distance of RFID label tag is reducing gradually.
The detectable distance of plating indium tin (1:9) alloy and thicknesses of layers relation are as shown in Figure 2.
embodiment 2:adopt indium stannum alloy as Coating Materials, indium tin ratio is 2:8.
Adopt the mode of vacuum plating, by indium stannum alloy evaporation in surface of plastic products, the coated film plastic product surface made by above technique sticks RFID label tag, and when chip frequency is 930MHz, readable distance is 30cm.Equally, the thickness of evaporation coating is about 90nm each time, and indium stannum alloy coatings thickness also can affect the detection operating range of rfid interrogator, and coatings is thicker, and the detectable distance of RFID is reducing gradually.The detectable distance of plating indium tin (2:8) alloy and thicknesses of layers relation are as shown in Figure 3.
embodiment 3:adopt pure indium as Coating Materials, indium content more than 99.9%.
Adopt the mode of vacuum plating, by pure indium metal evaporation in surface of plastic products, the coated film plastic product surface made by above technique sticks RFID label tag, and when chip frequency is 930MHz, readable distance is 33.2cm.Equally, the thickness of evaporation coating is about 90nm each time.Pure indium coatings thickness also can affect the detection operating range of rfid interrogator simultaneously, and coatings is thicker, and the detectable distance of RFID is reducing gradually.Compare indium stannum alloy coating, the detecting distance impact of pure indium thickness of coating on rfid interrogator is less, and the detectable distance of pure indium coating and thicknesses of layers relation are as shown in Figure 4.
Found through experiments, the metal alloy coating of different ratios, the distance (distance between rfid interrogator and wireless radio frequency identification mark (RFID)) that rfid interrogator can read has different.Indium tin (1:9) alloy, indium tin (2:8) alloy, pure indium (indium content more than 99.9%), in these three kinds of alloys, the interference of pure indium coating to RFID is minimum, and corresponding reading distance also farthest.By facts have proved, Alloy Plating rete is thicker, and detectable distance is reducing gradually.When alloy coating layer thickness reaches certain value, detectable distance is close to zero.
In the whole technological process of vacuum evaporation indium stannum alloy, the thickness controlling coating can normally read most important to RFID.We found through experiments, in certain distance, the normal reading of thickness of coating to RFID label tag has a significant impact, and thickness of coating is relevant with a lot of plated film factor, as the distance, the number of evaporating materials, the size of evaporation time, evaporation power etc. of film-coated part and evaporation source.Therefore, for this coating technique, reasonably control these coating influence factors well, the alloy layer of generation will directly affect the normal reading decipherment distance of RFID label tag.
Vacuum evaporation indium stannum alloy or pure indium metal, give surface of plastic products and have metal-like.Plastics and wireless radio frequency identification mark (RFID) through plating indium stannum alloy or pure indium metal process combinationally use, and ensure that the normal read-write capability of RFID, reach our expection object.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
