Embodiment 1

[0037] A scratch-resistant texture lettering film, such as figure 1 As shown, from bottom to top are PET release film 1, silicone oil release layer 2, resin molding layer 3, texture layer 4, and hot melt adhesive layer 5. The raw material component of the resin molding layer is polyester TPU 60KG, ABS15KG, stearic acid modified wollastonite powder 20KG (average particle size 4μm-6μm), ABS-G 3KG, polysiloxane 1KG, acrylic leveling agent 1KG.

[0038] The preparation method of the stearic acid-modified wollastonite powder is as follows: 25KG of wollastonite powder with an average particle size of 4 μm-6 μm, add 0.25 KG of stearic acid, stir, the speed is 900 r / min, the temperature is 80 ° C, and the time is 20 min , and then cooled to room temperature to remove larger particles to obtain stearic acid modified wollastonite powder.

[0039] refer to figure 2 , the preparation method of the scratch-resistant pattern lettering film is:

[0040] Coat a layer of silicone oil on a ...

Embodiment 2

[0042] A scratch-resistant textured lettering film, from bottom to top are PET release film, silicone oil release layer, resin molding layer, texture layer, hot melt adhesive layer, the raw material component of the resin molding layer is polyester TPU 60KG , ABS5KG, stearic acid modified wollastonite powder 10KG, ABS-G 1KG, polysiloxane 1KG, acrylic leveling agent 5KG.

[0043] The preparation method of the stearic acid modified wollastonite powder is as follows: 15KG of wollastonite powder with an average particle size of 4 μm-6 μm, add 0.18 KG of stearic acid, stir at a speed of 1000 r / min, a temperature of 120 ° C, and a time of 30 min. Then cool to room temperature, remove larger particles, and obtain stearic acid modified wollastonite powder.

[0044] The preparation method of the scratch-resistant pattern lettering film is as follows:

[0045]Coat a layer of silicone oil on a PET release film with a width of 1000mm and a thickness of 5c as a release layer; fully mix th...

Embodiment 3

[0047] A scratch-resistant textured lettering film, from bottom to top are PET release film, silicone oil release layer, resin molding layer, texture layer, hot melt adhesive layer, the raw material component of the resin molding layer is polyester TPU 70KG , ABS10KG, stearic acid modified wollastonite powder 10KG, ABS-G 5KG, polysiloxane 4.9KG, acrylic leveling agent 0.1KG.

[0048] Its preparation method is:

[0049] Coat a layer of silicone oil on a PET release film with a width of 1000mm and a thickness of 7.5c as a release layer; fully mix the raw material components of the above-mentioned resin molding layer to obtain a mixture, and send the mixture into a twin-screw extruder , the material is fully fused under the shearing, mixing and conveying of the screw to form a coating liquid, which is extruded from the gap of the extrusion nozzle under pressure, the temperature of each section of the twin-screw is 200°C-220°C, and the screw speed is 300r / min; The extrusion coati...

Abstract

The invention relates to the field of application of TPU materials, and provides a scratch-resistant grain lettering film and a manufacturing method thereof. The problem of poor scratch resistance ofa grain lettering film in the prior art is solved. The scratch-resistant grain lettering film comprises five parts, ie., a hot melt adhesive layer, a grain layer, a resin forming layer, a release layer and a release film, and the resin forming layer is prepared from, in percentages by weight, 60-70% of TPU, 5-15% of ABS, 10-20% of stearic acid-modified wollastonite powder, 1-5% of a compatibilizer, 1-5% of polysiloxane and 0-2% of a leveling agent. The scratch-resistant grain lettering film has strong scratch resistance, and can be applied to zipper film and a plurality of shoe and clothing thermal transfer products which need to have scratch resistance, and the shortcoming of the scratch irresistance of a grain lettering film on the existing market can be overcome.

Description

technical field [0001] The invention relates to the application field of TPU materials, in particular to a scratch-resistant textured lettering film made of TPU materials and a manufacturing method thereof. Background technique [0002] Textured lettering film is a thermal transfer product. Its principle is to directly contact the textured transfer film with the substrate, and transfer the texture layer on the transfer film to the substrate through the heating and pressure of the thermal transfer equipment. , generally consists of four parts: hot melt adhesive layer, texture layer, resin molding layer, and release film. The resin molding layer plays a role in shaping and protecting the pattern of the finished product after transfer, which mainly determines the performance and molding effect of the product. , which plays a vital role in the overall quality of the textured lettering film. [0003] Existing textured lettering films mostly use PET film, PVC film, PC film, etc. ...
