Abstract
The present invention refers to a process for demetallizing a retro reflective or reflective material with a radio frequency device, which consist in removing metal deposits adhered to the material by means of exposing the same to determined chemical solutions. The process is based on the flexographic, offset, screen printing methods or any method that uses printing rollers for transferring the chemical substance, in place of common inks, to the retro reflective or reflective material in order to subsequently insert the radio frequency device (aluminum or copper antenna) into the demetallized zone.
Description
Process of obtaining Reflective Material device with radio frequency device
Description of the invention
The present invention relates to a process for obtaining a device of retro reflective or reflective material used for the production of plate stickers or badges for all types of vehicles and road signs, which is characterized by a brightness effect without being Annoying to the eye as it reflects light in the same direction, with a radio frequency device.
In order to include a radio frequency device (formed by a chip and an antenna) it is necessary to carry out a process for the elimination of the content of metal (aluminum or other) of the retro-reflective or reflective material, which prevents transmission or reception, since the radiation is absorbed by the material and does not allow the radio frequency antenna to capture this energy and activate the chip device. The above is given no matter in which position the device is placed, since the effect of distortion / absorption of the radio waves (power) to activate the device are affected in any way. To avoid the above, the demetalizing process is carried out, which will be described below:
Figure 1 shows the process, which starts by removing the liner (inner protective layer of the metal) or material protector, which is exposed to a corrosive printing process type flexography, offset, screen printing or others. Once the printing method has been chosen, mechanical plates are generated with the patterns and areas to be demetallised and the demetallization process is started by exposing the metal to corrosive agents composed of sodium hydroxide. (Patent Application No. 010968 and 010969 in complement of Application No. 101 21 126 of the Patent Office of the German Republic)
CONFIDENTIAL 1 Subsequently, a fine demetalization is performed on grids (Figure 2) over the entire surface of the material to break conductivity and absorption of radio waves and allow them to be picked up by the antenna of the radio frequency device.
Figure 3 shows the process to stop the demetallizing process, where it is washed with water and subjected to a drying process, once the material is dry, it continues with the printing process, where with the printing heads the inks are applied and they are of fixed or variable information, and all this in line in WEB process or of coil.
Once this process is finished, a radio frequency device is placed in the de-metallised area as shown in Figure 4.
This demetallizing process can be applied to decals for all types of vehicles in a self-adhesive form with the automobile plates, platform tract, container, vehicular control applications or others with variable information of writing and reading and biometric information such as fingerprints, iris, facial, voice and other recognition with photography and applications of toxicology or other traffic infractions. We will call this device third plate.
It is also applied to metal plates made of galvanized sheet, acrylic polycarbonate or any other material, in which case the surface of the metal plate must be covered enough to place an insulator between the sheet and the device to allow proper transmission and reception of the Once the device is isolated and tucked in, the radio frequency device is placed and then laminated with the demetallized retro-reflective material for proper operation, as shown in Figure 5.
This process of demetallization is advantageous because it gives us a retro reflective or reflective material, which is not annoying to the naked eye since it reflects the light in the same direction, and in which a radio frequency device can already be inserted.
CONFIDENTIAL 2 that allows to transmit the signal to the outside or to receive it, without any type of interference. CONFIDENTIAL 3
Claims (1)
- Claims Having described my invention as above, I consider a novelty and claim of my property contained in the following clauses: That the present invention of demetallization of a retro reflective or reflective material with radio frequency device is achieved with the following process: That the reflective or reflective reflective material is subjected to a printing process such as flexography, offset, screen printing or others, where mechanical plates are generated with the patterns and areas to be demetallised and the demetallization process is started by exposing the metal to agents as sodium hydroxide. Subsequently, a fine demetalization is made in grids on all the material, thus allowing the absorption of radio waves, being captured by the antenna of the radio frequency device. That to stop this demetalization process at the desired time it is necessary to wash with water. That is subjected to a drying process, to continue in the print heads to apply the inks whether they are fixed or variable information as a printing process, all this online in web process or coil. That once the process is finished, it is possible to place a radio frequency device in the demetallised area, either in a material for decalcomania or for metal plates of galvanized sheet, acrylic polycarbonate or any other material. That the present invention is advantageous because it results in a retro reflective or reflective material, which is not annoying to the naked eye since it reflects the light in the same direction, and in which a radio frequency device can be inserted since allows to transmit the signal to the outside or to receive it, without any type of interference. CONFIDENTIAL 5? 4} a) ooz) d O? lO ^ Summary of the Invention The present invention relates to a demetallization process of retro reflective or reflective material with a radio frequency device, which consists in the removal of metal deposits adhered by means of the exposure of this material to certain chemical solutions. The process is based on the flexographic, offset, serigraphic or other printing method, which uses the printing rollers that will transfer the chemical substance in substitution of normal inks towards the retro reflective or reflective material, so that later the radio device is inserted frequency (aluminum or copper antenna) in the demetallised area.
