Embodiment 1

[0091] See figure 1 , 3 , a high-elastic silicone rubber lettering film, said high-elastic silicone rubber lettering film includes a load-bearing substrate 1, a release layer 2, a surface silicon rubber layer 3, an adhesive interface agent layer 5, and a TPU thermal insulation film sequentially connected from bottom to top. 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.

[0092] The carrying substrate 1 is a polyester frosted film with a thickness of 0.08 mm.

[0093] The thickness of the release layer 2 is 0.8 μm, the thickness of the surface silicone rubber layer 3 is 45 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 obtained by spraying the release liquid on the frosted surface of the polyester frosted film and dryin...

Embodiment 2

[0117] The difference between this embodiment and above-mentioned embodiment 1 is:

[0118] The carrying substrate 1 is a polyester frosted film with a thickness of 0.09 mm.

[0119] The thickness of the release layer 2 is 0.9 μm, the thickness of the surface silicone rubber layer 3 is 48 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 spraying the release liquid on the frosted surface of the polyester frosted film and drying it. The release liquid is composed of water-based fluorine release liquid and water in a weight ratio of 1:48 mixture.

[0121] Described surface layer silicone rubber layer 3 is made by surface layer silicone rubber, and described surface layer silicone rubber comprises the raw material of following weight portion:

[0122] Methyl vinyl silicone rubber 56 parts

[0123] Silicone rubber color masterbatch 38 parts

[0124] Pla...

Embodiment 3

[0143] The difference between this embodiment and above-mentioned embodiment 1 is:

Abstract

The invention relates to the technical field of thermal transfer lettering film, in particular to a highly elastic silicone rubber lettering film and a preparation method thereof. The highly elastic silicon rubber lettering film includes a bearing substrate, a release layer, and a surface layer sequentially connected from bottom to top A silicone rubber layer, an adhesive interface agent layer and a TPU hot-melt adhesive film; the adhesive interface agent layer is made of an adhesive interface agent, and the adhesive interface agent is an adhesive interface agent with two resin components. The silicone rubber lettering film of the present invention has the advantages of both silicone rubber material and TPU material, and has better comprehensive properties such as elasticity, tear resistance, weather resistance, yellowing resistance, and washing resistance, and is not easy to separate between layers, and is not easy to be exposed to sunlight. Discoloration, not easy to fade, washing fading rate ≤ 0.5%, mixed with other color materials, not easy to dye, high stability, easy to bond with various materials, high adhesive strength, not easy to fall off, good stability, delicate hand feeling, beautiful appearance Good strength and long 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 a preparation method thereof. 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 head gap extrusi...
