Abstract

The invention provides a kind of high peeling force disposable anti-fake label coating composition, including solid solute and solvent, described solid solute includes that component and the weight content in solid solute thereof are: methyl-etherified amino resins 20~70%, Hydroxylated acrylic resin 10~30%, acid anhydrides 10~20%, adhesion promoter 2~4%, organosilicon auxiliary agent 2~4%;Described solvent includes that component and weight content in a solvent thereof are: ethyl acetate 5~35%, n-butyl acetate 5~35%, butanone 5~40%, propylene glycol monomethyl ether 5~30%.The present invention uses amino resins, Hydroxylated acrylic resin and acid anhydrides to react, highly polar thermosetting system and PET film have higher binding strength, it is to avoid during manual operation, coating adheres on hand, but does not interferes with the rate of transform of coating.

Description

A kind of high peeling force disposable anti-fake label coating composition
Technical field
The present invention relates to a kind of high peeling force coating composition, particularly relate to a kind of high peeling force disposable anti-fake label and apply Feed composition.
Background technology
Present stage food packaging applications, such as salt, drinks etc., selected disposable anti-fake label, use scribbles more Thermoplastic propene's acid system of adhesive sticker.
There are the following problems in disposable anti-fake label system for modal thermoplastic acrylic resin system:
First, acrylic resin is relatively low with PET film attachment fastness, and during artificial transfer label, adhesive sticker can stick to your hands simultaneously Coating is sticked out from PET film, causes defect ware more;
Secondly, thermoplastic acrylic resin system crosslink density is relatively low, and anti-scratch effect is poor.
Content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of high peeling force disposable anti-fake label coating Composition, specifically a kind of heat curing-type disposable anti-fake label coating composition, utilize between different macromolecule resin React to improve crosslink density, thus make it have high peeling force, the feature of high anti-scratch.
The present invention is achieved by the following technical solutions:
The present invention provides a kind of high peeling force disposable anti-fake label coating composition, including solid solute and solvent;
Described solid solute include component and in solid solute weight content be:
Described solvent includes that component and weight content in a solvent thereof are:
Preferably, described solid solute includes that component and the weight content in solid solute thereof are:
Preferably, described acid anhydrides is small-molecular-weight acid anhydrides, such as phthalic anhydride, maleic anhydride etc..
Preferably, described adhesion promoter is highly polar molecular substance, such as pentaerythrite four-3-thiopropionate etc..
Preferably, described organosilicon auxiliary agent includes DC18, DC51, the organosilicon auxiliary agent producing for DOW CORNING.
Preferably, the weight of described solid solute and solvent is than for 1:(1~7).
Methyl-etherified amino resins and Hydroxylated acrylic resin are the Primary resins of whole coating composition, and the two carries out ether exchange Reaction, while improving crosslink density, not only increases solvent resistance, the erasibility of coating, also improves and PET base The attachment fastness of film;The introducing of acid anhydrides, is possible not only to make itself and Hydroxylated acrylic resin react raising crosslink density, improves Solvent resistance and anti-scratch, simultaneously its highly polar attachment fastness that more improve with basement membrane.
Adhesion promoter improves the binding strength aluminizing and plating aluminium and medium and coating composition in medium operation.
Organosilicon auxiliary agent improves the slipping on coating composition surface, adds rub resistance effect.
Compared with prior art, the present invention has a following beneficial effect:
(1) present invention uses thermosetting resin system, introduces methyl-etherified amino resins, Hydroxylated acrylic resin reaction to carry High crosslink density, is simultaneously introduced acid anhydrides, is possible not only to increase the tightness of coating composition and PET film, simultaneously again can be with Hydroxylated acrylic resin reacts, and increases the crosslink density of system, improves hardness, the anti-scratch of coating composition;
(2) the coating composition coating of present invention peeling force on a pet film is relatively big, molds, aluminizes and coats and does not do Glue shifts, even if hand adheres to adhesive sticker during manual operations, under also will not gluing the coating on PET film, but transfers to When on packaging base material, as long as somewhat exerting oneself, it is possible to tear PET film, and label has more preferable anti-scratch performance.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in those skilled in the art Member is further appreciated by the present invention, but does not limit the present invention in any form.It should be pointed out that, the common skill to this area For art personnel, without departing from the inventive concept of the premise, some deformation can also be made and improve.These broadly fall into Protection scope of the present invention.
