Problems solved by technology

However, when used for high-quality surface decoration materials such as mobile phone casings, buttons, car casings, and home appliance panel casings, the wear resistance and corrosion resistance of ordinary thermosetting coatings are not enough; Excellent wear resistance and corrosion resistance of coatings and light-curing coatings
However, the photocurable coating will produce a large volume change after the light is completely cured, which makes it difficult to guarantee the quality of the material with the holographic pattern obtained after the holographic transfer film is combined with the substrate.

Embodiment 1

[0040] This example is used to illustrate the method provided by the present invention.

[0041] Coat the release layer slurry (weight ratio of butyl acetate cellulose to acetone 40:60) by gravure printing on a base film with a width of 800mm (PET base film produced by Foshan Dupont Hongji Film Co., Ltd., with a thickness of 18um) , based on the total weight of the wear-resistant layer coating to be coated, the weight of the release layer slurry is 30wt%; then bake at 80°C for 15s to obtain a release layer with a thickness of 0.5um.

[0042] The above-mentioned release layer was coated with a dual-curing coating by gravure printing, and then cured at 70°C for 5 minutes in a combined drying tunnel produced by Shantou Far East Machinery Co., Ltd. to obtain a 4um thick semi-cured wear-resistant layer.

[0043] The composition of the above-mentioned dual-curing coating is: based on the total weight of the dual-curing coating, it includes 30wt% aliphatic urethane acrylate resin, 38...

Abstract

The invention discloses a method for preparing a material with holographic patterns, which comprises the following steps: forming a releasing layer, an abrasion-resistant layer, an information layer and a dielectric layer on a basement membrane in turn to obtain a holographic transfer membrane, and combining the holographic transfer membrane and a base material at one side of the dielectric layer, wherein the abrasion-resistant layer is formed by coating an abrasion-resistant layer paint on the surface of the releasing layer and then semi-curing the abrasion-resistant layer paint; and fully curing the abrasion-resistant layer after the holographic transfer membrane is combined with the base material to obtain the material with the holographic patterns. The material with the holographic patterns prepared by the method avoids the deformation of the abrasion-resistant layer paint during curing on the premise of ensuring the abrasion resistance and corrosion resistance of the material so as to improve the quality of a product.

Description

【Technical field】 [0001] The invention relates to a preparation method of a material with a holographic pattern. 【Background technique】 [0002] With the rapid development of holographic technology, molded holographic technology has also emerged as the times require. It is a comprehensive modern high-tech integrating multiple disciplines such as optics, electromechanics, surface chemistry, arts and crafts and relief printing. [0003] The traditional holographic transfer film is composed of a base film, a release layer, an information layer, a dielectric coating and a hot melt adhesive layer. When the transfer occurs, the film is separated from the information layer with the release layer, so that the information layer is exposed on the surface of the transferred sample. Since there is no protection on the surface of the information layer, after a long time of use, it is easy to cause pattern wear or erosion, which will affect the quality of the material after being combined...
