Abstract:
Research and development of photopolymerizable composite materials (PPC) with improved photochemical and physico-mechanical properties has been carried out. These properties allow the materials to be used in forming coatings and stereolithographic images, including in 3D printing technology. The effect of the type and amount of components in the polymerization composition on the photopolymerization processes of urethane methacrylates and acrylate oligomers, with the addition of organosilicon modifiers and tertiary amine methacrylates, when irradiated with LED lamps of different wavelengths, in the presence of photoinitiators, was studied. The effect of the type and number of photoinitiators on the optical and polymerization properties of materials and coatings was examined using a PLASMON-71 spectrometer. The analysis of the developed modifiers, which are oligomeric silane acrylates based on 3-glycidyl methacrylate (GMA) and 3-aminopropyltriethoxysilane (APTES), — as well as 3-methacryloxypropyl trimethoxysilane (MEMO) and the synthesized epoxyaminosiloxane oligomer product (EPAM), which is based on (3-glycidyloxypropyl) trimethoxysilane and APTES, showed potential for modifying PPC and for the targeted regulation of properties in accordance with technological purpose. Using the optimal amount of organosilicon modifiers ensures the photopolymer material has the best combination of physical, chemical, and physical-mechanical properties, significantly improving its performance characteristics depending on its intended use. The developed nanocomposite photopolymerization materials are used in manufacturing and decorating packaging, photoadhesives, optical adhesives, stamps, embossed Braille images for the blind, and stereolithographic recording of 3D information for printing volumetric images and other photoactive materials. Production tests have yielded positive results.
Keywords: photopolymerization, photoinitiator, oligomeric modifiers, photoactivity, nanocomposites, organosilicon oligomers, polymer matrix, kinetics, spectrophotometry, stereolithography.
