Embodiment 1

[0092] A kind of highly elastic silicon rubber lettering film, said high elastic silicon rubber lettering film comprises a bearing substrate 1, a release layer 2, a surface silicon rubber ink layer 3, an anti-translucent silicon rubber ink layer 4, which are connected sequentially from bottom to top. The adhesive interface agent layer 5 and the TPU hot melt adhesive film 6; the adhesive interface agent layer 5 is made of an adhesive interface agent, and the adhesive interface agent is an adhesive interface agent with two resin components.

[0093] The bearing substrate 1 is a polyester matte film with a thickness of 0.08mm; the thickness of the release layer 2 is 0.8 μm, the thickness of the surface silicone rubber ink layer 3 is 25 μm, and the anti-translucent silicone rubber ink The thickness of the layer 4 is 35 μm, the thickness of the adhesive interface agent layer 5 is 10 μm, and the thickness of the TPU hot melt adhesive film 6 is 80 μm.

[0094] The release layer 2 is ...

Embodiment 2

[0118] The difference between this embodiment and above-mentioned embodiment 1 is:

[0119] The bearing substrate 1 is a polyester matte film with a thickness of 0.09mm; the thickness of the release layer 2 is 0.9 μm, the thickness of the surface silicone rubber ink layer 3 is 28 μm, and the anti-translucent silicone rubber ink The thickness of the layer 4 is 38 μm, the thickness of the adhesive interface agent layer 5 is 11 μm, and the thickness of the TPU hot melt adhesive film 6 is 90 μm.

[0120] The release layer 2 is obtained by coating the frosted surface of the polyester frosted film with a release liquid and drying it. The release liquid is composed of a water-based fluorine release liquid and water in a weight ratio of 1:48. composition of the mixture.

[0121] The surface silicone rubber ink layer 3 is made of surface silicone rubber ink, and the surface silicone rubber ink includes 98 parts of silicone rubber color ink and 4 parts of liquid platinum vulcanizing ag...

Embodiment 3

[0144] The difference between this embodiment and above-mentioned embodiment 1 is:

[0145] The bearing substrate 1 is a polyester frosted film with a thickness of 0.10 mm; the thickness of the release layer 2 is 1.0 μm, the thickness of the surface silicone rubber ink layer 3 is 30 μm, and the anti-translucent silicone rubber ink The thickness of the layer 4 is 40 μm, the thickness of the adhesive interface agent layer 5 is 12 μm, and the thickness of the TPU hot melt adhesive film 6 is 100 μm.

[0146] The release layer 2 is obtained by coating the frosted surface of the polyester frosted film with a release liquid and drying it. The release liquid is composed of a water-based fluorine release liquid and water in a weight ratio of 1:50 composition of the mixture.

[0147] The surface silicone rubber ink layer 3 is made of surface silicone rubber ink, and the surface silicone rubber ink includes 100 parts of silicone rubber color ink and 3 parts of liquid platinum vulcanizin...

Abstract

The invention relates to the technical field of thermal transfer printing lettering film, and in particular, relates to a high-elasticity silicone rubber lettering film and a preparation method and anapplication method thereof. The high-elasticity silicone rubber lettering film comprises a load-bearing substrate, a release layer, a surface layer silicone rubber ink layer, an anti-photopermeable silicone rubber ink layer, an adhesive interfacial agent layer and a TPU hot melt adhesive film which are connected from bottom to top successively; the adhesive interfacial agent layer is prepared from an adhesive interfacial agent, and the adhesive interfacial agent is an adhesive interfacial agent containing dual-resin components. The silicone rubber lettering film has the advantages of both thesilicone rubber material and the TPU material, has good elasticity, tearing strength, weatherability, yellowing resistance, water washing resistance and other comprehensive properties, has layers noteasy to separate, is not easy to discolor or fade by sunlight exposure, and has the water-washing fading rate not less than 0.5%, is not easy to dye when being mixed and washed with materials with other colors, and is high in stability, easy to bond with a variety of materials, high in bonding strength, not easy to peel off, good in stability, delicate in hand feeling, good in aesthetic degree, and long in service life.

Description

technical field [0001] The invention relates to the technical field of thermal transfer lettering film, in particular to a highly elastic silicone rubber lettering film and its preparation method and application method. Background technique [0002] Thermal transfer lettering film is a newer process for making patterns or LOGOs on cloth or textiles than screen printing. Most of the lettering films sold on the market are lettering films made of TPU material. The process is to first coat the back of the biaxially stretched polyester film with a 200-line anilox roller to coat the back coating liquid of the protective layer, and then further Oven drying; then apply a release agent on the front of the biaxially oriented polyester film with a comma scraper, and dry in the oven; then apply the color layer TPU ink to the release layer of the biaxially oriented polyester film with a comma scraper On the surface, enter the oven to dry the solvent in the ink; then use the hot-melt die...
