Water transfer film with concave and convex effects and preparation method thereof

Abstract

The invention relates to the technical field of a water transfer film and particularly relates to a water transfer film with concave and convex effects and a preparation method thereof. The water transfer film comprises a water-soluble base film layer, a concave pattern layer, a film removal protection layer and an ink pattern layer, and the layers are orderly pasted from top to bottom. The concave pattern layer comprises an aqueous coating. The aqueous coating comprises, by weight, 5% to 6% of matting powder, 30% to 35% of a film former, 1.5% to 2% of an aqueous wax emulsion, 2% to 3% of a water-based thickening aid, 8% to 10% of propylene glycol monoethyl ether, 1% to 1.5% of an aqueous defoamer, 6% to 8% of n-butanol and the balance of water. Through the water transfer film, the transferred patterns have concave-convex effects and through combination with the patterns, the realistic effect is produced.

Description

technical field

[0001] The invention relates to the technical field of water transfer printing films, in particular to a concave-convex effect water transfer printing film and a preparation method thereof. Background technique

[0002] At present, the patterns transferred by the water transfer film produced on the market are all flat, and there is no concave-convex effect to match the pattern. There are mainly the following defects: 1. The pattern plane has no three-dimensional effect. 2. After water transfer printing, a large amount of water-soluble PVA film is dissolved in water and discharged, causing a large amount of environmental pollution. 3. There is a large amount of PVA in the use of the transfer printing pool, which will precipitate out after a long time and seriously affect the finish of the finished workpiece.

Examples

Embodiment 1

[0041] See figure 1 , a concave-convex effect water transfer film, comprising a water-soluble base film layer 1, a concave layer 2, a release protective layer 3 and an ink pattern layer 4, which are laminated sequentially from top to bottom, and the concave layer 2 is made of water-based paint Formed by coating, the water-based coating is composed of the following raw materials in weight percentage:

[0042]

[0043] The matting powder is fumed silica produced by Degussa, Germany, whose model is OK412.

[0044] Described film-forming agent is the polyvinyl alcohol of model PVA205 that Japanese Kuraray produces.

[0045] The aqueous wax emulsion is a BYK-AQUACER498 aqueous wax emulsion produced by BYK in Germany.

[0046] The water-based thickening aid is the water-based thickening aid of the model K-STAY720 produced by King's in the United States.

[0047] The water-based defoamer is a BYK-024 water-based defoamer produced by BYK, Germany.
