Problems solved by technology

[0002] As a new type of synthetic leather, silicone leather has excellent weather resistance, such as super hydrolysis resistance, light resistance, salt spray resistance, solvent resistance, etc., no VOC release during the production process, will not pollute the environment, and has very good Anti-fouling, easy to clean, excellent flame retardancy and good touch, etc., so it is more and more widely used. Most of the silicone leather with texture on the market is printed on release paper or PET film. Texture, apply liquid silicone on the release paper or PET film to rub the texture, but because the texture printed on the release paper and PET film is very shallow, the texture will be more obvious after rubbing on the silicone layer, and the traditional It is difficult to reuse the release paper and it is easy to break the release paper, or the texture accuracy is not clear after peeling off

preparation example Construction

[0022] A method for preparing an organic silica gel membrane with clear lines, comprising the steps of:

[0023] Step 1, prepare the substrate film 4 with optical visual texture on the surface;

[0024] Step 2, making the surface of the substrate film with optical visual texture have an easy-to-peel function, so as to obtain a master mold, and the easy-to-peel function makes it easy to peel off the master mold after coating silica gel;

[0025] Step 3: Coating the liquid silicone on the master mold, peeling off the liquid silicone from the master mold after curing, and preparing the silicone film 1 with an optical texture on the surface.

[0026] Preferably, in step 2, the surface of the substrate film with optical visual texture is subjected to vacuum electroplating to form an electroplated base film 6 with an easy-to-peel function. The vacuum pressure for vacuum electroplating is 0.001Pa. The electroplating base film is chrome-plated base film or copper-plated base film or ...

Embodiment 1

[0039]Embodiment one, 1) choose the PET base material that thickness is 0.1mm, carry out vacuum electroplating to the PET base material surface with nano-scale optical texture, make master model, the vacuum pressure during vacuum plating is 0.001Pa, make organic The peel force between the silica gel film and the electroplating base film is less than 25g, the vacuum pressure for vacuum plating is 0.001Pa, the electroplating base film is chrome-plated base film or copper-plated base film or nickel-plated base film or aluminum-plated base film, nickel-plated base film The film is not easy to oxidize and can be used repeatedly for several months. The copper-plated base film can increase the texture brightness and make the texture transferred on the surface of the silicone more dazzling. The gloss of the electroplating base film is 0-60. The surface texture is more delicate and complete. When the gloss is 60, the surface texture is incomplete after the silica gel is peeled off, and ...

Embodiment 2

[0040] Embodiment two, 1) select the PET base material that thickness is 0.1mm, apply UV adhesive 5 to the surface of PET base material, the temperature is 40 ℃ when coating UV topcoat, utilize UV ​​adhesive coating 5 to spread on the base material of tool pattern On the surface of the film 4, the UV glue completely penetrates into the texture of the substrate film 4 to form corresponding textures, and the UV glue is cured and hardened by irradiating UV light. There is no limit to the thickness of the master model of the texture and the coating of the UV topcoat, and it is set according to the different needs of different customers. After the liquid silica gel is solidified, it is peeled off from the master mold to obtain a patterned silicone film. The surface of the silicone film processed by the process of the present invention has nano-scale PET optical UV texture, and the texture is clear.

Abstract

The invention relates to an organic silica gel membrane with clear lines. The organic silica gel membrane comprises an organic silica gel membrane body, the upper surface of the organic silica gel membrane body is provided with a hot melt gluing layer, and the lower surface of the organic silica gel membrane body is provided with an optical texture layer. A preparation method of the organic silicagel membrane includes the steps that 1, a base material film is coated with UV glue; 2, the lines are impressed on the UV glue to prepare a female die with optical visual texture; 3, vacuum electroplating is carried out on the surface, with the optical visual texture, of the female die to form an electroplated base film; 4, the electroplated base film is coated with liquid silica gel, the liquidsilica gel is stripped from the female die after being solidified, and the organic silica gel membrane with the PET optical UV lines on the surface is prepared. In the ultraviolet irradiation environment, the lines are embossed on the UV glue layer through an embossing press with a line pressing roller, the UV glue layer is coated with the liquid silica gel for line rubbing, and an organic siliconlayer with the lines can be obtained after the liquid silica gel is solidified and stripped.
