Embodiment 1

[0043] (1) Use a coater (Xi'an Taihua Machinery Co., Ltd., QHTB-1200 series coater) to coat a layer of transfer coating on a PET film with a corona value of 35 dyne;

[0044] (2) Use a vacuum metallizer (Leybold PRO-M1300, Germany) to coat the coating surface of the PET film obtained in step (1) with aluminum, the thickness of the aluminum layer is 0.20 μm, which is the dyed aluminum layer 3;

[0045] (3) Use a composite peeling machine (Xi'an Honghe Machinery Co., Ltd., HZFT-1200F) to coat a layer of water-based adhesive on the surface of the dyed aluminum layer 3, and the coating amount is 1.2g / m 2 , and combined with the base paper layer, peel off the PET film after drying, and obtain a silver cardboard with a base paper layer 1, an adhesive layer 2, and a dyed aluminum layer 3;

[0046](4) Use a coater (Xi'an Taihua Machinery Co., Ltd., QHTB-1200 series coater) to coat a layer of water-based transparent varnish on the surface of the dyed aluminum layer 3 in step (3), and t...

Embodiment 2

[0067] The preparation method of the silver cardboard of this embodiment is the same as that of Example 1, the only difference being that before coating the water-based transparent varnish, the surface corona treatment is carried out to the dyed aluminized layer 3 to improve the contact between the siphon microporous layer 4 and the dyed plated layer. The degree of bonding between the aluminum layers 3 .

[0068] The prepared silver cardboard with siphon micropores has a surface tension of 0.70N / m, a micropore diameter of 0.6μm, and a micropore density of 10 7 piece / cm 2 , The micropores run through the siphon microporous layer to 0.07μm below the surface of the dyed aluminum layer, which has a high siphon effect on the ink. The folding endurance of this product is 85 times, and the stiffness is 16.5g / cm 3 , burst resistance 90 (%), surface gloss (75 ° gloss meter) is 60Gs, in line with various color printing packaging requirements.

[0069] The prepared gold and silver car...

Embodiment 3

[0075] (1) Use a coater (Xi'an Taihua Machinery Co., Ltd., QHTB-1200 series coater) to coat a layer of transfer coating on a PET film with a corona value of 46 dyne;

[0076] (2) Use a vacuum metallizer (Leybold PRO-M1300, Germany) to aluminize the coating surface of the PET film obtained in step (1), the thickness of the aluminum layer is 0.30 μm, which is the dyed aluminized layer 3;

[0077] (3) Use a composite peeling machine (Xi'an Honghe Machinery Co., Ltd., HZFT-1200F) to coat a layer of water-based adhesive on the surface of the dyed aluminum layer 3, and the coating amount is 2.4g / m 2 , and compounded with the base paper layer, peel off the PET film after drying, and then paint the aluminum surface to obtain a gold cardboard with a base paper layer 1, an adhesive layer 2, and a dyed aluminized layer 3;

[0078] (4) Use a coater (Xi'an Taihua Machinery Co., Ltd., QHTB-1200 series coater) to coat a layer of water-based transparent varnish on the surface of the dyed alum...

Abstract

The invention discloses gold-silver cardboard with siphon micropores, and a preparation method and an application thereof. The preparation method comprises the steps: employing a composite transfer way to prepare gold-silver cardboard, then coating a layer of transparent water-based varnish on the surface, after drying and cooling, carrying out corona treatment of the coated surface, and thus obtaining the gold-silver cardboard with the siphon micropores. The prepared gold-silver cardboard comprises a base paper layer, an adhesive layer and a dyed aluminized layer. The upper surface of the base paper layer is coatedly provided with the adhesive layer, the adhesive layer is provide with the dyed aluminized layer, and the dyed aluminized layer is provided with a siphon micropore layer having an ink absorption property. Compared with ordinary gold-silver cardboard, the gold-silver cardboard provided by the invention has higher surface tension, and enables the ink absorption property to be greatly improved; after printing of ink, the gold-silver cardboard has higher firmness of an ink layer; even if a large area of the surface is coated with gloss oil, the gold-silver cardboard can allow the scratch resistance of the printed surface to meet standard requirements, and can be applied to pharmaceuticals, middle-high grade tobacco and wine, cosmetics and other various product packaging.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a gold and silver cardboard with siphon micropores, a preparation method and application thereof. Background technique [0002] Gold and silver cardboard is a commonly used packaging material, which has a gorgeous metallic appearance and good barrier properties, and is widely used in various color printing packaging fields. At present, most gold and silver cardboards are made by compound transfer method. The product surface is dense and smooth, non-absorbent to ink, not easy to print with ink, prone to printing failures such as weak ink layer and incomplete drying. In order to improve the printing quality of gold and silver cardboard, the printing process often adopts "deep ink thin printing" or "secondary printing" to speed up the drying speed of ink. However, the above methods not only affect the production speed, but also increase the difficulty of the process, a...
