Description
Technical field
The present invention is to be related to a kind of ink, is to be related to a kind of UV cured printing inks specifically, belongs to technical field of ink.
Background technology
Due to acrylic resin have good guarantor's light colour retention, weatherability, fast drying, easy construction, be easy to construct, weight
The advantages of applying and do over again, therefore thermoplastic acrylic resin is most popular resin in solvent-based ink and UV ink.
At present, most of drinks, essence class, perfume class, liquid air freshener class packaging, bottle cap, and many electronic equipment casings
It is required for being decorated using ink or is protected.
And acrylic resin can not occur further crosslinking when being used as the main resin of ink in film forming procedure, therefore will
Expect hardness higher, typically require that the molecular weight and glass transition temperature of resin are higher, but can so reduce resin
To the adhesive force of base material, and the flow leveling for influenceing ink.Further, since thermoplastic acrylic resin contains more ester
Base, hydroxyl, these groups enable that resin alcohol resistance in itself is poor, and resistance to corrosion is low, therefore also limit it and apply model
Enclose.Although occurring some ethanol-tolerant acrylic resins in the market, no matter domestic or import old brand ethanol-tolerant propylene
Acid resin, its ethanol-tolerant degree highest also only two, 300 times, and also it is expensive, it is only suitable for specific use.
In order to overcome acrylic resin in itself alcohol resistance difference shortcoming, it is necessary to be modified research to it.Chinese patent
