Abstract
The present invention refers to a process for demetallizing a retro reflective material of PVC or PET or variations of both plastic compounds 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 material in order to subsequently insert the radio frequency device (aluminum or copper antenna) into the demetallized zone.
Description
Process of obtaining device of retro reflective material of PVC or PET with radio frequency device
Description of the invention
The present invention relates to a process for obtaining a device of retro-reflective material of PVC or PET or variations of these two plastic compounds used for the production of plate stickers or badges for all types of vehicles and road signs, with a radio frequency device.
In order to include a radio frequency device (consisting of a chip and an antenna) it is necessary to carry out a process for the removal of the metal (aluminum or other) content of the retro-reflective PVC or PET material, which prevents the 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 device of the chip. 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:
The process starts by removing the liner (protective inner layer of the metal) or material protector, which is exposed to a corrosive printing process such as 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)
The retroflective material is placed in an inner layer of PVC with a copper antenna embedded in the plastic material and then applied with adhesive on the reverse (reverse) CONFIDENTIAL of the material without the antenna touching the areas of the metal while retaining the reflective properties and the proper transmission reception. Subsequently, a fine demetalization is performed in grids over the entire surface of the material to break conductivity and the absorption of radio waves and allow them to be picked up by the antenna of the radio frequency device.
Figure 1 shows another way of preparing the material, which is a process (heat incrustation by ultrasound) in which a copper wire antenna is integrated directly into the retro-reflective material on the PVC or PET material to later be connected to the device. The radio frequency chip is connected either self-adhering by thermal fusion or by the use of acrylic or epoxy resins with the previously demetallised material completely on the surface where the radio frequency device is placed and partially in fine grids as mentioned above.
This process of demetallization is advantageous because it gives us a retro reflective material of PVC or PET or variations of these two plastic compounds, in which a radio frequency device can be inserted since it allows to transmit the signal to the outside or to receive it, without any type of interference.

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 PVC or PET material or variations of these two compounds with radio frequency device is achieved with the following process: That the material undergoes a printing process type flexography, offset, screen printing or others, where mechanical plates are generated with the patterns and areas to demetallize and begins with the demetallization process to expose the metal to agents such as sodium hydroxide . That an inner layer of PVC is placed with a copper antenna embedded in the plastic material and then applied with adhesive on the back (inverse) to the material without the antenna touching the areas of the metal while retaining the reflective properties and proper reception. Subsequently, a fine demetallization 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 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 sheet, galvanized, acrylic polycarbonate or any other material. That the invention was presented is advantageous because it results in a retro reflective material in which a radio frequency device can be inserted since it allows the signal to be transmitted to the outside or to receive it, without any type of interference.
