Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] refer to figure 1 and figure 2 , a method for embedding a radio frequency tag into a silicon rubber leather label, characterized in that: the method comprises the following steps:
[0029] Step 1, according to the shape of the silicone rubber label to be made, engrave a mold on a metal that is easy to engrave and has good thermal conductivity;
[0030] Step 2, placing the mold horizontally, injecting the solution into the mold for the first time, until the liquid level covers all the engraving patterns in the mould, and the highest position a of all engraving patterns;
[0031] Step 3. Put a piece of high-temperature vulcanized silicone rubber raw rubber sheet, the highest point of the effective cavity in the mold is c position, set The thickness of raw film is 0.8l~1.2l;
[0032] Step 4, place the radio frequency label on the raw film, and ensure that the...

The invention relates to a method for embedding a radio-frequency tag into a silicon rubber label, comprising the following steps: engraving a mould according to the shape of the silicon rubber label to be manufactured; horizontally placing the mould, and infusing a solution into the mould for the first time till a liquid level submerges all engraved patterns inside the mould or the highest positions a of all the engraved patterns; placing a high-temperature raw vulcanized silicon rubber sheet into the mould, wherein the highest point of an effective cavity inside the mould is a position c; setting the thickness of the raw vulcanized silicon rubber sheet into 0.81-1.21; placing the radio-frequency tag on the raw vulcanized silicon rubber sheet, and ensuring that the circumference of the radio-frequency tag at least keeps a preset distance from mould metal; infusing liquid silicon rubber into the mould, wherein a liquid surface submerges the radio-frequency tag; heating the mould, and stopping heating till the liquid silicon rubber tightly fixes the radio-frequency tag; placing the raw vulcanized silicon rubber sheet again to brim the mould; and heating and pressurizing so that the two raw vulcanized silicon rubber sheets are vulcanized, thus the silicon rubber label embedded with the radio-frequency tag is manufactured. The invention enhances the work efficiency and reduces the manufacture cost.
Description
technical field [0001] The invention relates to a method for embedding a radio frequency tag into a silicon rubber leather tag. Background technique [0002] In the prior art, high-temperature vulcanized silicone rubber is high-molecular-weight polyorganosiloxane (ie, raw rubber) added with reinforcing fillers and other various additives, using organic peroxides as vulcanizing agents, and pressurized (molded, extruded). Pressing, calendering) or injection molding, and cross-linked into rubber at high temperature. This rubber is generally referred to as silicone rubber. The vulcanization of high temperature vulcanized silicone rubber is generally carried out in two stages. The first stage is to mix the raw silicone rubber, reinforcing agent, additive, vulcanizing agent and structure control agent, and then pressurize the compounded material in the metal mold. Heating molding and vulcanization, the pressure is about 50 kg / cm2, the temperature is 120-130 ° C, and the time is ...
