[0025] like Figures 1-4As shown, this utility model provides a decorative identification element, which may be, but is not limited to, a badge, a refrigerator magnet, or a sticker.

[0026] The decorative signage specifically includes a base 100, a pattern layer 200 and a transparent elastomer 300 disposed on the front of the base 100.

[0027] The base 100 can be made of metal, silicone / silicone gel, or plastic, etc., and has a certain degree of hardness, serving to support the pattern layer 200 and the transparent elastomer 300.

[0028] A transparent elastomer 300 is wrapped around the pattern layer 200 on the front of the base 100, and the hardness of the transparent elastomer 300 is less than that of the base 100.

[0029] The pattern layer 200 is a film with a pattern on one side, and the edge of the transparent elastomer 300 is bonded to the base 100.

[0030] During manufacturing, the patterned film is placed on the base 100, and then a transparent elastomer 300 is wrapped around the film to fix the film between the base 100 and the transparent elastomer 300.

[0031] Transparent elastomer 300 can be made of transparent silicone / silicone gel, transparent fluororubber, transparent polyurethane elastomer, transparent polyolefin elastomer, transparent polysiloxane-polyurethane copolymer, transparent polyether ether ketone or transparent hydrogel, etc. The light transmittance of transparent elastomer 300 is ≥85%@550nm, and the hardness (Shore) is 0-30 degrees.

[0034] Definition: Formation of cross-linked structures through condensation reactions (such as reactions with water or alcohols), releasing small molecule byproducts (such as methanol or ethanol).

[0035] Features: Good transparency, curing speed is affected by ambient humidity, and moderate mechanical strength.

[0036] Specific types: hydroxyl-terminated polydimethylsiloxane (PDMS) condensation system (most common, cross-linked via organotin catalyst);

[0037] Alkoxy-terminated polymethylphenylsiloxane condensation system (the introduction of phenyl can improve temperature resistance and refractive index);

[0038] Amino-terminated polysiloxane condensation system (fast curing speed, suitable for rapid prototyping).

[0039] 2. Addition-cured transparent silicone rubber / silicone gel

[0040] Definition: Crosslinked with vinyl groups (Si-Vi) via an addition reaction (platinum catalyst) through silicon-hydrogen bonds (Si-H), without small molecule byproducts.

[0041] Features: Excellent transparency (no by-product residue), no shrinkage during curing, and a wide range of adjustable mechanical properties (from soft gel to hard rubber).

[0042] Specific types: Vinyl-terminated PDMS and hydrogen-containing silicone oil addition system (general type, best transparency);

[0043] Vinyl-terminated polymethylvinylsiloxane and hydrogen-containing phenyl silicone oil system (high temperature resistance, radiation resistance, and slightly lower transparency than PDMS);

[0044] Fluorine-modified addition-cure silicone rubber (containing fluorine groups to improve chemical resistance and maintain transparency).

[0045] 3. Radiation-crosslinked transparent silicone rubber / silicone gel

[0046] Definition: Polysiloxane molecular chains are cross-linked by radiation such as ultraviolet light (UV) or electron beams without the need for chemical catalysts.

[0047] Features: Fast curing speed (seconds), high transparency, suitable for precision molding.

[0048] Specific types: Transparent PDMS containing photosensitive groups (such as acrylate groups) (UV-cured, most commonly used);

[0049] Pure PDMS cross-linked system via electron beam radiation (no additives, extremely transparent, suitable for medical-grade products).

[0050] 4. Thermoplastic transparent silicone rubber (TPV silicone rubber)

[0051] Definition: A reversible cross-linked structure formed through physical cross-linking (such as microphase separation), which can be repeatedly processed.

[0052] Features: Good transparency, combining the elasticity of silicone rubber with the processability of plastics.

[0053] Specific types: thermoplastic elastomers blended with polyolefins (such as PP) and PDMS (transparency is affected by the size of the dispersed phase);

[0054] Thermoplastic blends of fluoropolymers and fluorosilicone rubber (excellent chemical resistance, moderate transparency).

[0055] Based on physical properties such as hardness and elastic modulus, transparent silicone rubber / silicone gel can be classified as follows:

[0056] 1. Transparent silicone gel (low hardness / low cross-linking density)

[0057] Characteristics: Hardness ≤10 Shore A (or lower, semi-fluid dynamic), elastic modulus <1MPa, light transmittance ≥90% (400-800nm).

[0058] Specific application types: Transparent silicone gel for medical filling (such as breast implants, scar repair, which must meet ISO10993 biocompatibility requirements);

[0059] Transparent silicone gel for electronic packaging (e.g., moisture-proof packaging of LED chips and sensors, low stress);

[0068] Specific types: Physically foamed addition-type silicone gel (foamed by an inert gas, such as CO2, with a slight decrease in transparency);

[0069] Chemically foamed condensation silicone gel (gas is generated by the decomposition of a foaming agent; bubble size needs to be controlled to maintain transparency).

[0070] Transparent fluororubber

[0071] Fluorinated polyether segments have transparency close to that of silicone and better chemical resistance (such as oil, acid and alkali resistance), but slightly lower elasticity.

[0072] Transparent polyurethane elastomer (TPU)

[0073] Polyester / polyether type TPU has high transparency and high elasticity. Its performance at room temperature is similar to that of silicone, but its temperature resistance is poor (≤120℃).

[0074] Transparent polyolefin elastomer (POE)

[0075] Ethylene-octene copolymer has good transparency, moderate elasticity, and lower cost than silicone, making it suitable for low-temperature applications.

[0076] Transparent polysiloxane-polyurethane copolymer (SPU)

[0077] The block copolymerization of siloxane and polyurethane combines the weather resistance of silicone with the high strength of polyurethane, and has excellent transparency.

[0078] Transparent polyetheretherketone (PEEK) elastomer (modified)

[0079] By reducing crystallinity through copolymerization, transparency is achieved, and it is resistant to high temperatures (>200℃), with an elastic modulus close to that of silicone.

[0081] Polyvinyl alcohol (PVA) hydrogels and polyethylene glycol (PEG) hydrogels have overlapping functions with silicone gels in the biomedical field (such as contact lenses), with comparable transparency but superior water resistance.

[0082] This invention covers the pattern layer 200 on the front of the base 100 with a transparent elastomer 300. On the one hand, the pattern of the decorative logo can be observed through the transparent elastomer 300, making it more three-dimensional. On the other hand, when playing with it, the transparent elastomer 300 can be pressed, which is very stress-relieving and enhances its playability and fun.

[0083] In some embodiments, the back of the base 100 is provided with a connector for mounting the decorative sign.

[0084] Optionally, such as Figure 2 As shown, the connector has a hook 110 for attaching with a pin. This decorative identifier can be used as a badge or pin. When attaching, the pin can be hooked onto the hook 110 of the connector, and then the decorative identifier can be attached to clothing, bags, hats, backpacks, or other items using the pin.

[0085] Optionally, such as Figure 3 As shown, the connector is a magnet 120. This decorative label can be used as a refrigerator magnet; when fixed, it can be attracted and fixed to the refrigerator by the magnet 120.

[0086] It should be noted that the decorative identification parts in this embodiment are not limited to badges, emblems and refrigerator magnets, and the structure of the connectors is not limited to the above-mentioned methods. At the same time, the shape of the decorative identification parts is not specifically limited and can be round, square or other shapes.
