specific Embodiment approach

[0018] A dielectric rubber body for encapsulating sensors, the formula of the dielectric rubber body is as follows:

[0019]

[0020] The rubber mixing process is divided into two stages of mixing production. Add raw rubber (including: chlorinated butyl rubber, styrene-butadiene rubber, natural rubber), light calcium carbonate, carbon black, stearic acid, magnesium oxide, phenolic tackifying resin (code name 203) materials to one section of the rubber compound formula, and the rest The compounding agent is added in the two-stage feeding formula. The rubber material of the first stage is mixed and manufactured in the GK400N internal mixer; the rubber material of the second stage is manufactured in the internal mixer, and the rubber material is pounded on the tablet machine for three rounds, and then the tablet is cooled and parked. The rubber material in the section can only enter the next processing step after it has been parked for 4 hours.

[0021] The principle of this...

Abstract

The invention relates to a dielectric rubber body for packaging a sensor. The dielectric rubber body is characterized in that the formula thereof comprises 60-70 parts of chlorinated butyl rubber, 10-20 parts of butadiene styrene rubber, 20-30 parts of natural rubber, 20-30 parts of light calcium carbonate, 30-40 parts of carbon black, 5-10 parts of conductive carbon black, 1-3 parts of stearic acid, 2-5 parts of magnesium oxide, 1-5 parts of octyl phenol-phenolic resin, 3-6 parts of zinc oxide, 1-3 parts of N-tertiary butyl-2-benzothiazole sulfenamide, 0.5-2 parts of tetramethyl thiuram disulfide, and 0.5-2 parts of insoluble sulphur. The dielectric rubber body disclosed by the invention is used for a conductive radiofrequency device in tire; the device comprises a radio assembly and an antenna, and can be used for tracking and recording data during manufacturing, sales and use; and the measurement range covers temperature, pressure or other physical parameters in tire. During the loading process of a sensor, the conductive material with a certain dielectric constant and a certain adhesive force disclosed by the invention is chosen, so that the device can be firmly connected with a tire and can be used for transmitting data more stably; simultaneously, via high elasticity and good mechanical property of rubber, the device can withstand the stress brought by cyclic deformation of the tire excellently.

Description

technical field [0001] The invention relates to a sensor packaging structure, especially packaging a sensor and an antenna in a conductive, dielectric material, and also relates to a dielectric rubber body for manufacturing the sensor packaging. Background technique [0002] In the prior art, there is a magnetic detector having a magnetoresistive element for detecting magnetoresistance, and a protection circuit composed of a plurality of electronic components. An electronic device that integrates sensors with the tire, which can identify and track functions during manufacturing, distribution and use. These electronic devices can be used to measure physical parameters such as temperature and pressure during the use of the tire. Many systems utilize radio frequency communications between the tires and external monitoring and interrogation devices. [0003] There are several systems in the prior art that are mounted to the surface of the tire or wheel or incorporated in the t...
