Embodiment 1～2

[0029] The preparation of a color sheet with a structure of APET / glue / INK / PE and a thickness of 300 μm includes the following steps:

[0030] 1) Select a PE film with a surface tension value of 38-42 dynes, and install a blank printed composite substrate PE film on the unwinding device;

[0031] 2) Select 10 parts of polyurethane printing ink (purchased from Suzhou Zhongya, green ink UMT99-R500 in embodiment 1, red ink UMT99-R105 in embodiment 2), and add 0.25 parts of polyurethane ink curing agent (purchased from Suzhou Zhongya Asia, grade CVL#12), put the two into the ink tank and mix them, and use the ink stirring stick to stir for 5 minutes;

[0032] 3) carry out back printing to the PE film by gravure printing or flexo printing with the mixed back printing ink prepared in step 2;

[0033] 4) Rewind according to the number of winding meters. After printing, place the printed PE printing film in an environment of 30-50°C and humidity 55-75%RH, and mature for more than 12 h...

Abstract

The invention discloses a compound colored sheet and a preparation method and an application thereof. The compound colored sheet comprises a base layer, an inner printing ink layer, a glue layer and asheet layer, wherein the base layer is a transparent high molecular film; the inner printing ink layer is composed of polyurethane inner printing ink and a polyurethane printing ink curing agent in amass ratio of 10: (0.1-0.5); the glue layer is a polyurethane adhesive; and the sheet layer is a transparent high molecular sheet. According to the compound colored sheet, the color of the sheet is regulated by means of the inner printing ink layer, and the color is simple to regulate and easy to control. The sheet layer can be the transparent high molecular sheet, so that the loss of the manufacturing process can be reduced greatly. The prepared compound colored sheet is relatively small in chroma and is obviously superior to that of a color sheet prepared by a conventional method in the aspect of chroma. In addition, the peeling strength of the compound colored sheet is also relatively high and has excellent application performance.

Description

technical field [0001] The invention belongs to the technical field of flexible packaging printing and composite technology, and specifically relates to a novel composite color sheet and its preparation method and application. Background technique [0002] Conventional color sheets are obtained by adding a certain proportion of color masterbatch in the sheet manufacturing process, but this method has the following disadvantages: ①It is difficult to control the color difference between batches ②It can only make a single solid color sheet ③Production switching of different color sheets In view of this, it is necessary to develop new color sheets to overcome the above-mentioned problems of conventional color sheets and their manufacturing processes. Contents of the invention [0003] In view of the technical problems of difficult color difference control and high loss in the color sheet manufacturing process in the prior art, the purpose of the present invention is to provide...
