Abstract
The invention discloses an RFID (radio frequency identification) tag for tracing cold-chain logistics, which comprises an RFID tag and a waterproof film for coating the RFID tag; the waterproof membrane is made of a polyethylene composite material and comprises the following components in parts by weight: 120 parts of low-density polyethylene, 15-22 parts of rubber composite material, 20-28 parts of filler, 0.5-1 part of antioxidant, 3-8 parts of plasticizer and 6-12 parts of flame retardant. The modified additive can enable the two rubbers to be combined more tightly, enables the rubber composite material to be dispersed more uniformly in the polyethylene composite material, and further improves the waterproof performance, the low-temperature resistance and the mechanical property of the polyethylene composite material.
Description
Technical Field
The invention relates to the field of RFID (radio frequency identification) tags, in particular to an RFID tag for tracing cold-chain logistics.
Background
The Internet of things (Internet of things) is an important trend of the current information networking development, and is called the third wave of the world information industry after computers and the Internet, and the radio frequency identification technology RFID is one of the key technologies of the Internet of things. The ultrahigh frequency RFID technology is a non-contact automatic identification technology, automatically identifies a target object through a radio frequency signal and acquires related data, and has the advantages of wireless read-write identification, strong signal penetration capability, long distance, long service life, good environmental adaptability, simultaneous identification of multiple tags and the like, so that the ultrahigh frequency RFID technology is widely applied in recent years.
The basic operating principle of RFID technology is not complex. After the tag enters a magnetic field sent by a reader, a radio frequency signal sent by the reader is received, and product information (Pasivetag, passive tag or passive tag) stored in a chip is sent out by means of energy obtained by induction current, or a signal with a certain frequency (Activetag, active tag or active tag) is actively sent out; the information is read and decoded by the interpreter and then sent to the information processing center of the system for relevant data processing. The passive RFID tag with low cost, strong capability of adapting to complex environment, long service life and multi-tag reading capability plays a more important role in more and more application scenes. Cold Chain Logistics (Cold Chain Logistics) generally refers to a system engineering that refrigerated and frozen foods are in a specified low-temperature environment all the time in all links from production, storage, transportation and sale to the stage before consumption, so as to ensure the quality of the foods and reduce the loss of the foods. However, the existing RFID tags have poor water resistance and low temperature resistance, and information is easily blurred and lost or falls off from the surface of logistics in cold-chain logistics transportation.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide an RFID tag for tracing cold-chain logistics.
The purpose of the invention is realized by adopting the following technical scheme:
an RFID label for tracing cold-chain logistics comprises an RFID label and a waterproof film wrapping the RFID label;
the waterproof membrane is made of a polyethylene composite material and comprises the following components in parts by weight:
120 parts of low-density polyethylene, 15-22 parts of rubber composite material, 20-28 parts of filler, 0.5-1 part of antioxidant, 3-8 parts of plasticizer and 6-12 parts of flame retardant.
Preferably, the rubber composite material is prepared by mixing polybutadiene rubber, dimethyl silicon rubber and a modifying additive according to the weight ratio of 2-5:3-6: 0.2-0.8.
