Rubber composition for packaging RFID electronic tag

Abstract

The invention discloses a rubber composition for packaging an RFID electronic tag. The rubber composition is characterized by comprising the following components in parts by weight based on 100 partsof natural rubber: 30-50 parts of white carbon black, 6-10 parts of a coupling agent, 1-4.5 parts of an anti-aging agent, 2.8-4.2 parts of sulfur, 0.8-1.5 parts of an accelerant, 0-0.5 part of an anti-scorching agent and 3-7 parts of an active agent, and meanwhile, the rubber composition also comprises 0.5-5 part of Rhein aflux powder. According to the invention, a 100% pure natural rubber systemis adopted to improve the strength, fatigue resistance and viscosity of the rubber composition; and 100% pure white carbon black is adopted, the resistance performance of the white carbon black is better than that of carbon black, the influence of sizing materials, steel wire frameworks and other materials around the electronic tag on electric waves emitted by the electronic tag can be effectivelyprevented, and therefore the read-write distance of the electronic tag can be increased.

Description

technical field [0001] The invention belongs to the technical field of tire rubber, and in particular relates to a rubber composition for encapsulating RFID electronic tags. Background technique [0002] With the intelligentization and informatization of the tire use process, the use of tires with RFID (Radio Frequency Identification Devices) electronic tags is being tried by major public transport and logistics companies. This type of tire with electronic tags can use radio frequency reading and writing devices to write data information in the tire's entire life cycle, such as manufacturing, use, and failure, and can effectively record and trace all tire information. identity card". [0003] At present, there are two technologies for implanting RFID electronic tags into tires. One is to paste the packaged RFID electronic tags on the outer wall or inner wall of the sidewall. damage, but there is a risk that the label will fall off during use; another mainstream technology ...

[0003] At present, there are two technologies for implanting RFID electronic tags into tires. One is to paste the packaged RFID electronic tags on the outer wall or inner wall of the sidewall. damage, but there is a risk that the label will fall off during use; another mainstream technology is to implant the packaged electronic label inside the tire during the molding process, which can effectively prevent the label from falling off. High viscosity and fatigue resistance requirements, otherwise there is a risk of early damage to the tire
