Abstract:

Lamination is the process of gluing and packaging a transparent film to printed products to improve shopfront, protect it from pollution and moisture, and to increase mechanical strength and durability. For the processes of conjunction the protective film and printing products, special adhesive systems, including photopolymerization are used.

The development and investigations of UV-sensitive polymerization compositions (PhPC) based on oligourethane and oligoester acrylates using synthesized silicon-organic oligomeric modifiers have been carried out. Modification of PhPK allows obtaining nanostructured photopolymer materials for manufacture and decoration of printing products by lamination and substitute imported materials. Taking into account the peculiarities of the laminating products technology, a composition and method for the synthesis of photopolymerization compositions in castor oil with the optimal photoinitiator system selection have been developed. The developed PhPC composition conform to technical requirements for photoglue and is characterized by high photosensitivity (less 2-3 seconds of exposure), as well as adhesive strength during various nature materials gluing. Silicon aminoacrylate modifiers, characterized by increased functionality and different amino group activity, were developed and synthesized. The inclusion in the base polymer matrix of a certain number of structured fragments of organosilicon oligomers forms a nanoscale system with desired properties, which allows the creation of new composite materials with controlled properties. Using of modifiers in PhPK significantly improves the physicochemical and mechanical properties of compositions and coatings.

The designed modified nanocompositions have achieved to substitute of imported materials, enhance product quality, and improve the technological process of printed products lamination and packaging. Production tests at print services in Kyiv and L’viv were carried out.

 

Keywords: photopolymerization, oligomeric modifiers, photoactivity, nanocomposites, organosilicon compounds, lamination, kinetics, photosensitivity, adhesion.
