Abstract

The invention provides a high-stripping-force disposable anti-counterfeiting label paint composition which comprises a solid solute and a solvent. The solid solute comprises the following components in percentage by weight: 20-70% of methyl ether amino resin, 10-30% of hydroxy acrylic resin, 10-20% of acid anhydride, 2-4% of adhesion promoter and 2-4% of organic silicon assistant. The solvent comprises the following components in percentage by weight: 5-35% of ethyl acetate, 5-35% of n-butyl acetate, 5-40% of butanone and 5-30% of propylene glycol monomethyl ether. By reacting the amino resin, hydroxy acrylic resin and acid anhydride, the high-polarity system has higher binding strength with the PET (polyethylene terephthalate) film, thereby preventing the coating from being attached to the hand during manual operation without influencing the transfer ratio of the 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 coating composition.
Background technology
Present stage food packaging applications, such as salt, drinks etc., selected disposable anti-fake label, uses the thermoplastic propene's acid system scribbling non-setting adhesive more.
There are the following problems in disposable anti-fake label system for modal thermoplastic acrylic resin system:
First, acrylic resin and PET film attachment fastness lower, during artificial transfer label, non-setting adhesive can stick to your hands and coating be sticked out from PET film, causes defect ware more;
Secondly, thermoplastic acrylic resin system cross-linking density is lower, and scuff effect is poor.
Summary of the invention
For defect of the prior art, the object of this invention is 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 the reaction between different macromolecule resin to improve cross-linking density, thus make it have the feature of high peeling force, high scuff.
The present invention is achieved by the following technical solutions:
The invention provides a kind of high peeling force disposable anti-fake label coating composition, comprise solid solute and solvent;
Described solid solute comprises component and weight content is in solid solute:
Described solvent comprises component and weight content is in a solvent:
Preferably, described solid solute comprises component and the weight content in solid solute is:
Preferably, described acid anhydrides is small-molecular-weight acid anhydrides, as Tetra hydro Phthalic anhydride, maleic anhydride etc.
Preferably, described adhesion promoter is high polar molecule material, as tetramethylolmethane four-3-mercaptopropionic acid ester etc.
Preferably, described organosilicon auxiliary agent comprises DC18, DC51, is the organosilicon auxiliary agent that DOW CORNING is produced.
Preferably, the weight ratio of described solid solute and solvent is 1:(1 ~ 7).
Methyl-etherified aminoresin and Hydroxylated acrylic resin are the Primary resins of whole coating composition, and the two carries out ether exchange reaction, while improving cross-linking density, not only increase the solvent resistance of coating, erasibility, also improve the attachment fastness with PET basement membrane; The introducing of acid anhydrides, not only can make itself and Hydroxylated acrylic resin react and improve cross-linking density, improves solvent resistance and scuff, and its strong polarity improves the attachment fastness with basement membrane more simultaneously.
Adhesion promoter improves the binding strength aluminizing and plate 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 following beneficial effect:
(1) the present invention adopts thermosetting resin system, introduce methyl-etherified aminoresin, Hydroxylated acrylic resin reaction to improve cross-linking density, introduce acid anhydrides simultaneously, not only can increase the tightness of coating composition and PET film, can react with Hydroxylated acrylic resin again simultaneously, the cross-linking density of increase system, improves the hardness of coating composition, scuff;
(2) coating composition coating of the present invention peeling force is on a pet film larger, mold pressing, aluminize and coat non-setting adhesive and shift, even if hand adheres to non-setting adhesive during manual operations, also under the coating in PET film can not being glued, but when transferring on packaging base material, as long as exert oneself a little, just PET film can be torn, and label has better scuff resistance.
