Abstract

The utility model discloses an electronic tag, which comprises a tag body and is characterized in that the tag body is covered by a silicon rubber layer. The silicon rubber layer is made of high-temperature rubber which is vulcanized at low temperature through a nano composite technology. Since the tag body is covered by the silicon rubber layer and the silicon rubber layer is made of high-temperature rubber which is vulcanized at low temperature through the nano composite technology, the electronic tag has the advantages of high strength, high elasticity and good tear resistance.

Description

A kind of electronic tag

Technical field

The utility model relates to a kind of electronic tag, specifically a kind of intensity height, elasticity and the good electronic tag of anti tear.

Background technology

The principle of work system of existing electronic tag is made up of card, card reader and background controller.The course of work is as follows: (1) card reader outwards sends carrier signal through antenna; (2) after card enters the perform region of card reader, the resonant tank of being made up of telefault and electric capacity in the card receives the carrier signal that card reader is launched, the radio frequency interface module of card chips signal thus produces supply voltage, reset signal and system clock, makes chip " activation "; (3) chip reads control module the data in the storer is modulated on the carrier wave behind phase modulation coding, gives card reader through the loopback of card internal antenna; (4) card reader carries out delivering to background computer after demodulation, the decoding to the card backhaul signals that receives; (5) background computer is made corresponding processing and control according to the legitimacy of card number at different application.

Summary of the invention

The purpose of this utility model provides a kind of intensity height, elasticity and the good electronic tag of anti tear.

The purpose of this utility model is achieved through the following technical solutions.

A kind of electronic tag comprises label body, it is characterized in that: described label body coats one deck silastic-layer outward.

Described silastic-layer is by the nano combined high-temp glue that obtains carrying out cryogenic vulcanization.

The utility model compared with prior art has the following advantages:

The utility model coats one deck silastic-layer outside label body, silastic-layer is for to carry out cryogenic vulcanization by the nano combined high-temp glue that makes.The utlity model has the good advantage of intensity height, elasticity and anti tear.

Fig. 1 is the structural representation of the utility model electronic tag.

Embodiment

Below in conjunction with accompanying drawing the utility model electronic tag is described in further detail.

As shown in Figure 1, the utility model electronic tag comprises label body 1, and label body coats one deck silastic-layer 2 outward, and silastic-layer is for obtaining high-temp glue and can carry out cryogenic vulcanization by nano combined making.Obtain high-temp glue and can carry out cryogenic vulcanization by nano combined making, can keep a series of physical properties of high-temp glue sulfuration, defective chip not again, thus can large-area popularization and use electronic tag.Silicon rubber is a kind of macromolecular elastomer of inorganic and organic character, because the Si-0 key bond energy (443.5kJ/ mole) of molecular backbone is more much higher than the C-C key bond energy (355kJ/ mole) of ordinary rubber molecular backbone, because of a little silica gel have: 1, the low-surface-energy of low surface tension has every excellent properties such as hydrophobic, froth breaking, antiseized, lubricated, glazing.2, good electrical insulation properties has that dielectric loss is excellent, proof voltage, anti-electric arc, anti-corona and an excellent water repellency.3, weatherability, anti-ozone and radiation resistance can reach decades at physical environment following serviceable life.4, heatproof characteristic, not only can be high temperature resistant but also can and low temperature can use in a very wide temperature range.5, workability, resistance to acids and bases is better, life cycle is long, cost is low.6, silica gel also has good elasticity and flexibility, and shock resistance is good, anti-impact force.Because a series of good characteristics of silica gel, so the silica gel electronic tag has carried the series of advantages of silica gel, it is wide to have usable range, uses and stablizes, and cost is low, and the scope of popularization is big.Silica gel can be divided into high temperature vulcanized type and room temperature vulcanized two big classes by its curing temperature, and high-temp glue is mainly used in makes various rubbers, and room temperature glue then mainly is to use as bonding agent, fill material or mould.Heat vulcanized silicone rubber is a most important class in the organosilicon product, ethylene methacrylic silicon rubber (VMQ) is topmost kind among the HVT, be commonly called as high-temp glue, ethylene methacrylic silicon rubber (rubber) is colourless, odorless, nontoxic, the jelly that does not have mechanical impurity, rubber adds suitable reinforcing agent on demand, constitution controller, vulcanizing agents etc. are mixing together, compression molding or extrusion molding then heat up, make various goods through post vulcanization again, its goods have excellent electric insulation, arc resistant, corona, the electric spark ability is strong, waterproof, moistureproof, anti-impact force, shock resistance is good, has the physiology inertia, performances such as gas penetration potential.Room temperature vulcanized silicone rubber generally comprises add-on type and condensed type two big classes, add-on type room temperature glue is to be basic glue with the linear polysiloxane with ethene, to contain siloxane is crosslinking chemical, cross-linking reaction takes place under in room temperature to middle temperature and become elastic body in the presence of catalyzer.Condensed room temperature vulcanized silicone rubber is to be reflected as feature with the condensation between silicon hydroxyl and other active substances, can crosslinkedly become elastomeric silicon rubber under room temperature.A series of good physical properties such as the rubber intensity of high-temp glue sulfuration, elasticity can be protected electronic chip better, and defective is need be high temperature vulcanized, and electronic chip can not bear high temperature.Room temperature vulcanized silicone rubber is out of question on temperature, and defective is not enough on intensity, elasticity, the tearing toughness, can not be applied to the overlayer of electronic tag.Carry out cryogenic vulcanization by the nano combined high-temp glue that makes, overcome the defective of the two, keep the advantage of the two, thereby can promote and use electronic tag in large area.

Claims

1. an electronic tag comprises label body, it is characterized in that: described label body coats one deck silastic-layer outward.

2. electronic tag according to claim 1 is characterized in that: described silastic-layer is by the nano combined high-temp glue that obtains carrying out cryogenic vulcanization.
