Abstract
The invention relates to a technology transfer film with an unsmooth hand feeling. The film is composed of a PET base film, a back coating, which is painted on one surface of the PET base film, a release layer, a hard layer, a wood-grain pattern layer, a background color layer, and a glue layer, wherein the release layer, the hard layer, the wood-grain pattern layer, the background color layer and the glue layer are painted on the other side of the PET base film in sequence, and the wood-grain pattern layer is composed of the following raw materials in percentage by weight: 80 to 90% of color layer printing ink, and 10% to 20% of microcapsule foaming agent. The transfer film is characterized in that a wood-grain pattern layer containing a microcapsule foaming agent is added. During the painting and drying process, sodium bicarbonate in the microcapsule foaming agent is decomposed and foam is generated, so wood-grain patterns with a mimetic unsmooth wood-touch hand feeling will be printed on the PET base film, the stereo perception is very strong, the wood resources are saved, the product class is lifted, and the transfer film has a very high market promotion value.
Description
technical field
The invention belongs to printing technology, be specifically related to a kind of heat transfer film that prints out the concavo-convex sensation of real hand touch solid wood and preparation method thereof.
Background technology
Solid wood furniture Chang Yiqi natural wood true qualities are looked people, naturally betray a kind of honesty, sedate U.S., meet the psychological needs that people from modern metropolitan cities advocates the Nature, thereby flourishing long time.Yet under solid wood furniture fancy price pressure, many consumers hang back, then have turned one's attention to imitating solid wood furniture.
At present, although have a lot of imitating solid wood furnitures and board product on market, its surface grain pattern presents by pasted with solid wood sheet or employing emulation PVC film mostly, and all has certain defect: the former easily occurs sticking up skin phenomenon, affects service life; The empty grained shape of latter, is but difficult to present the texture of wood grain, and fidelity is poor.Traditional Wood thorn transfer film can Wood-grain-imitating third dimension, but need to make wood by methods such as long-time slaking or UV solidify, stings mould, complicated operation.
Summary of the invention
For overcoming prior art deficiency, the object of the invention is to provide a kind of concave-convex hand feeling technique transfer film, and it has real hand and touches the concavo-convex sensation of solid wood, has extremely strong third dimension.
The invention also discloses the preparation method of above-mentioned concave-convex hand feeling technique transfer film.
For achieving the above object, the present invention adopts following technical scheme:
A concave-convex hand feeling technique transfer film, its by PET basement membrane, be coated in the back coating of PET basement membrane one side, and the release layer, hard formation, grain pattern layer, background color layer and the glue layer that are coated in successively from inside to outside PET basement membrane another side form; Described grain pattern layer is made by following materials by weight percentage: chromatograph ink 80-90%, microcapsule foamer 10-20%.
Concrete, described microcapsule foamer is made by EVA resin, sodium acid carbonate, toluene and anti-solvent; Described anti-solvent is one or more in absolute ethyl alcohol, isopropyl alcohol and butanone; The mass ratio of described EVA resin and sodium acid carbonate is 1:0.33-0.5.Wherein, the preferred VA content of EVA resin is at 25-35%.The addition of toluene is generally 4-5 times of EVA weight resin.
Described microcapsule foamer obtains through following method: by EVA resin thermosol in toluene, until temperature, be down to 40 degree and add sodium acid carbonate when following, use high-speed shearing emulsion machine to disperse 2-3h, add anti-solvent (anti-amount of solvent is generally 6-8 times of EVA weight resin) to make its cohesion encystation, abandon supernatant, then obtain microcapsules slurry with anti-solvent washing; Microcapsules slurry is layered on to dry glass or enamel plate surface, stirs and make toluene and anti-solvent evaporates and disperse to be split into microcapsules, after screening, obtaining particle diameter is the microcapsule foamer of 2-5 micron.
Described chromatograph ink is made by following materials by weight percentage: polyamide 15-20%, and pigment 10-15%, dispersant 0.3-0.5%, surplus is solvent.Solvent can be conventional isopropyl alcohol, toluene etc.
In the present invention, pigment can be selected carbon black fast light, that heat resistance is good, rutile titanium dioxide, iron oxide yellow etc., use polyamide as matrix resin, toluene, isopropyl alcohol are as solvent, resin mixes with pigment after heating for dissolving in solvent, and add certain polycarboxylate sodium's dispersant, and according to concrete color, requiring to carry out proportioning mixing, grinding, acquisition can meet the chromatograph ink that serviceability requires.
The preparation method of above-mentioned concave-convex hand feeling technique transfer film, it comprises the following steps:
1) back coating is coated on to the surface of PET basement membrane one side, dries, enter into subsequent processing;
2) release layer is coated on to the surface of the other side of PET basement membrane, dries, enter into subsequent processing;
3) hard formation is coated on to release layer surface, dries, enter into subsequent processing;
4) chromatograph ink and microcapsule foamer are mixed, be printed on hard formation surface and form grain pattern layer, dry, enter into subsequent processing;
5) background color layer is printed on to grain pattern layer surface, dries, enter into subsequent processing;
6) at background color layer surface brush glue, dry, obtain concave-convex hand feeling technique transfer film.
In the present invention, the raw material of back coating, release layer, hard formation and background color layer is prepared according to this area routine techniques, and wherein, the raw material of background color layer forms preferably identical with the chromatograph ink in grain pattern layer in the present invention.Innovative point of the present invention has been to have increased in transfer film the grain pattern layer containing microcapsule foamer, in coating drying course, in microcapsule foamer, sodium acid carbonate reduces foaming, on PET basement membrane, can print out and there is the wood texture that true hand touches the concavo-convex sensation of solid wood, and then be coated with hot transfer printing glue, obtain concave-convex hand feeling technique transfer film.The hard formation (protective layer) that grain pattern layer surface is provided with to shield.
Compared to the prior art, beneficial effect of the present invention:
Compare with normal wood thorn film, between the PET basement membrane in transfer film of the present invention and release layer, without wood thorn pattern, after transfer printing, directly peel off indefectible; Grain pattern layer is below hard formation, and pattern is subject to hard formation protection, and wearability is good.This transfer film has real hand and touches the concavo-convex sensation of solid wood, has extremely strong third dimension, can be when saving natural timber rapid improving product class, there is high market popularization value.In addition, concave-convex hand feeling technique transfer film of the present invention directly can be used after coating, and preparation method is simple, and production efficiency is high, easy to operate.
