A kind of special transfer film of ceramics and preparation method thereof
Technical field
The present invention relates to transfer technical field of membrane, and in particular to a kind of special transfer film of ceramics and preparation method thereof.
Background technology
Transfer film is called transfer membrane, is that the pattern layer that will be printed in advance is transferred in specific article, certain to overcome
Article is difficult to the problem of directly printing.Such as ceramic film-making, due to the hardness of ceramics is big, in fragile, weight, it is difficult to using passing
Required pattern is directly printed on ceramics by the printing process of system, it is therefore desirable to which transfer film transfers pattern on ceramics.
Based on the gluing of ceramic blank plate roller coating and then transferring, this glue is generally liquid glue for ceramics transfer on the market at present,
Poor adhesive force is just fallen after soaked, and easy tos produce wrinkle and bubble in production process entirely.Major defect has:1, blanket roller
The glue flatness of painting is undesirable, easy tos produce water wave and steam bubble.2, the bigger product of the glue quantity of blanket roller coating glue at
This is heavy, and is easier to generate the stain caused by dust, high rejection rate.3, the complex process of blanket gluing, equipment cost
It is high.
Invention content
In order to overcome shortcoming and defect existing in the prior art, the purpose of the present invention is to provide a kind of special turn of ceramics
Die, with good transferring effect, adhesive force is high, the smooth bubble-free of transfer surface, and yields is high, and Costco Wholesale is low.
Another goal of the invention of the present invention is to provide a kind of preparation method of the special transfer film of ceramics, has transfer
Simple process and low cost, efficient feature.
The purpose of the invention is achieved by the following technical solution:
A kind of special transfer film of ceramics, is followed successively by base membrane layer, release layer, pattern layer, gum layer, the gum from top to bottom

Print can melt, and penetrate into the gap of ceramic surface, be finally fitted in ceramics and pass through photocuring reaction, light-initiated with TPO
Agent and closing curing agent chemically react, and improve adhesion strength and adhesive force, and further hardening is adhered to, and improve its stability and attached
Put forth effort.
Wherein, the UV solidified resins are hard polyaminoester acrylic paint.The typical products of the substance produce for Asia
The trade mark be SE-400 product, high-quality, stability is strong, and adhesive force is good.
Wherein, the closing curing agent is the enclosed type polyisocyanate curing agent based on hexamethylene diisocyanate,
Closing NCO content is 10-12%, and Typical Representative is 3175 type product of Bayer, and obtained ceramic Special back glue is high-quality, attached
Put forth effort strong.
Wherein, the adhesion promoter is vinyl trichlorosilane, vinyltrimethoxysilane, three ethoxy of vinyl
Any one of base silane or γ-glycidol ether propyl trimethoxy silicane.Preferably γ-glycidol ether propyl trimethoxy
Base silane improves the intensity of composite material, improves caking property, improves dry/wet compressive strength.
Wherein, the wetting agent is that 5% fluorine oxygroup modified organic silicon is dissolved in methyl-isobutyl ketone, has wetting, levelling, resists
The comprehensive performance of oil and defoaming.Wetting agent it is preferable to use DOW CORNING DC-7244 products as the present invention.
A kind of preparation method of the special transfer film of ceramics, includes the following steps:
