Technologie de polym\u00e9risation UV et photo-initiateurs<\/strong><\/h1>\n

Le s\u00e9chage UV est une technologie de pointe respectueuse de l'environnement, \u00e9conome en \u00e9nergie et tr\u00e8s performante.<\/p>\n

En raison des caract\u00e9ristiques des mat\u00e9riaux adh\u00e9sifs UV - notamment leur r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, leur large champ d'application et leur r\u00e9sistance \u00e0 la corrosion chimique - ils sont utilis\u00e9s pour coller les composants des moteurs d'avion et pour assembler les engins spatiaux.<\/p>\n

\"\"Applications du s\u00e9chage par lumi\u00e8re UV dans l'industrie de la sant\u00e9<\/b><\/strong><\/p>\n

Les syst\u00e8mes de sources lumineuses LED UV ont \u00e9t\u00e9 largement adopt\u00e9s dans le domaine m\u00e9dical en raison de leur capacit\u00e9 \u00e0 durcir rapidement les adh\u00e9sifs photo-initi\u00e9s, \u00e9liminant ainsi la n\u00e9cessit\u00e9 d'utiliser des agents de liaison volatils. Les adh\u00e9sifs polym\u00e9risables aux UV offrent des avantages significatifs, notamment des \u00e9conomies d'\u00e9nergie, une r\u00e9duction de la consommation, des temps de polym\u00e9risation acc\u00e9l\u00e9r\u00e9s, une efficacit\u00e9 de production accrue et une int\u00e9gration transparente dans les processus automatis\u00e9s.<\/p>\n

\"\"Applications de la polym\u00e9risation par lumi\u00e8re UV dans l'impression 3D<\/b><\/strong><\/p>\n

L'impression 3D par photopolym\u00e9risation est l'une des technologies de prototypage rapide les plus avanc\u00e9es \u00e0 l'heure actuelle, offrant une grande pr\u00e9cision d'impression et une viabilit\u00e9 commerciale. Ses avantages, notamment sa faible consommation d'\u00e9nergie, sa rentabilit\u00e9, sa grande pr\u00e9cision, ses finitions de surface lisses et son excellente reproductibilit\u00e9, la rendent largement applicable dans de nombreux secteurs de haute technologie. Par exemple, l'impression de prototypes de moteurs de fus\u00e9e aux structures complexes permet d'analyser les sch\u00e9mas d'\u00e9coulement des gaz, ce qui contribue \u00e0 la conception de moteurs plus compacts avec une meilleure efficacit\u00e9 de combustion. Cela am\u00e9liore consid\u00e9rablement l'efficacit\u00e9 de la R&D pour les composants complexes et raccourcit les cycles de d\u00e9veloppement de l'automobile. En outre, elle permet l'impression directe de moules ou de moules invers\u00e9s pour le prototypage rapide.<\/p>\n

Classification des sources de lumi\u00e8re UV<\/b><\/strong><\/p>\n

En fonction des sources de lumi\u00e8re de polym\u00e9risation, la photopolym\u00e9risation se divise principalement en deux cat\u00e9gories : la polym\u00e9risation traditionnelle par lampe \u00e0 mercure et la polym\u00e9risation \u00e9mergente par LED UV. Par rapport au durcissement par lampe \u00e0 mercure traditionnelle, le durcissement par LED UV pr\u00e9sente \u00e9galement certaines limites. La diff\u00e9rence la plus importante r\u00e9side dans le fait que le spectre \u00e9mis par les lampes \u00e0 mercure traditionnelles couvre presque toute la gamme des longueurs d'onde UV, alors que le durcissement par LED UV est actuellement limit\u00e9 \u00e0 la bande UVA de grande longueur d'onde en raison des contraintes technologiques du mat\u00e9riel et des consid\u00e9rations de co\u00fbt.<\/p>\n

\"\"Comparaison du spectre d'\u00e9mission entre les lampes \u00e0 mercure et les sources lumineuses LED UV<\/p>\n

Photoinitiateurs<\/b><\/strong><\/p>\n

Les photo-initiateurs repr\u00e9sentent une proportion relativement faible des formulations photopolym\u00e9risables, g\u00e9n\u00e9ralement de l'ordre de 2%-5%, mais ils jouent un r\u00f4le essentiel.<\/p>\n

Pour que la r\u00e9action de photopolym\u00e9risation se produise, les photo-initiateurs doivent absorber la lumi\u00e8re ultraviolette \u00e9mise par la source de lumi\u00e8re UV pour g\u00e9n\u00e9rer des radicaux libres. Ces radicaux libres d\u00e9clenchent alors la r\u00e9action de polym\u00e9risation, qui permet au produit de prendre sa forme finale.<\/p>\n

The emission spectrum of the UV light source must match the absorption spectrum of the photoinitiator. Traditional photoinitiators like 1173<\/a> and 184 exhibit maximum absorption at short-wavelength UVC regions, making them more suitable for curing with conventional mercury lamps.<\/p>\n

En revanche, les LED UV \u00e9mettent principalement de la lumi\u00e8re dans quelques bandes sp\u00e9cifiques, telles que 365 nm, 385 nm, 395 nm et 405 nm. Les photo-initiateurs \u00e0 base d'oxyde de phosphine pr\u00e9sentent une absorption relativement forte dans ces bandes, ce qui les rend largement applicables dans les syst\u00e8mes LED UV.<\/p>\n

\"\"Photoinitiateur de radicaux libres<\/p>\n

Photoinitiateurs<\/b><\/strong><\/p>\n

Les photo-initiateurs sont des composants essentiels des mat\u00e9riaux photopolym\u00e9risables. Ils absorbent l'\u00e9nergie rayonnante, subissent des modifications chimiques lors de l'excitation et g\u00e9n\u00e8rent des interm\u00e9diaires r\u00e9actifs (radicaux libres ou cations) capables d'initier des r\u00e9actions de polym\u00e9risation.<\/p>\n

En fonction de la longueur d'onde de la lumi\u00e8re absorb\u00e9e, les photo-initiateurs peuvent \u00eatre class\u00e9s en photo-initiateurs ultraviolets (longueur d'onde 250nm-400nm) et photo-initiateurs de lumi\u00e8re visible (longueur d'onde 400nm-700nm). Selon le m\u00e9canisme de photopolym\u00e9risation, ils sont class\u00e9s en photo-initiateurs de type radicalaire et en photo-initiateurs de type cationique.<\/p>\n

Les initiateurs radicaux peuvent \u00eatre subdivis\u00e9s en deux types en fonction de leurs m\u00e9canismes de g\u00e9n\u00e9ration de radicaux : les initiateurs de type clivage (\u00e9galement appel\u00e9s initiateurs de type I) et les initiateurs de type d\u00e9gagement d'hydrog\u00e8ne (\u00e9galement appel\u00e9s initiateurs de type II).<\/p>\n

Photoinitiateurs radicaux de type craquage<\/b><\/strong><\/p>\n

Les photo-initiateurs radicaux de type fissuration se r\u00e9f\u00e8rent \u00e0 des mol\u00e9cules qui, lorsqu'elles absorbent de l'\u00e9nergie lumineuse, passent \u00e0 un \u00e9tat singlet excit\u00e9 et subissent ensuite un croisement intersyst\u00e8me vers un \u00e9tat triplet excit\u00e9. Dans l'\u00e9tat excit\u00e9 singulet ou triplet, la structure mol\u00e9culaire devient instable et les liaisons faibles subissent un clivage homolytique. Cela g\u00e9n\u00e8re des radicaux actifs primaires qui initient la polym\u00e9risation et la r\u00e9ticulation des oligom\u00e8res et des diluants actifs.<\/p>\n

Cracking-type radical photoinitiators are predominantly arylalkyl ketone compounds, including phenylcoumarins and their derivatives (e.g., benzoic acid ethers), phenylcoumaric acid and its derivatives (e.g., 651), phenylacetone derivatives (e.g., DEAP), \u03b1-hydroxyketone derivatives (e.g., 1173, 184, 2959), \u03b1-aminoalkylphenylacetones (907, 369), and acylphosphine oxides (TPO, TPO-L<\/a>, 819).<\/p>\n

Photo-initiateurs radicaux qui \u00e9liminent l'hydrog\u00e8ne<\/b><\/strong><\/p>\n

Les photo-initiateurs qui \u00e9liminent l'hydrog\u00e8ne sont des mol\u00e9cules photo-initiatrices qui absorbent l'\u00e9nergie lumineuse, subissent une excitation et un croisement intersyst\u00e8me pour atteindre l'\u00e9tat excit\u00e9 triplet, puis subissent une r\u00e9action bimol\u00e9culaire avec un co-initiateur - un donneur d'hydrog\u00e8ne. Par transfert d'\u00e9lectrons, elles g\u00e9n\u00e8rent des radicaux actifs qui initient la polym\u00e9risation et la r\u00e9ticulation des oligom\u00e8res et des diluants r\u00e9actifs. Les principaux exemples sont les benzoph\u00e9nones et leurs d\u00e9riv\u00e9s, les thioanthraquinones (ITX, DETX) et les anthraquinones (2-EA).<\/p>\n

Les co-initiateurs sont des donneurs d'hydrog\u00e8ne utilis\u00e9s en conjonction avec des photo-initiateurs qui captent l'hydrog\u00e8ne. Sur le plan structurel, ils contiennent tous au moins une amine tertiaire en position \u03b1-carbone, et sont principalement des compos\u00e9s d'amine tertiaire. Ils r\u00e9agissent avec l'\u00e9tat excit\u00e9 des photo-initiateurs \u00e0 lib\u00e9ration d'hydrog\u00e8ne pour former des complexes de radicaux excit\u00e9s. L'atome d'azote perd un \u00e9lectron et l'hydrog\u00e8ne sur le carbone \u03b1 adjacent \u00e0 l'azote devient fortement acide, s'\u00e9chappant facilement sous forme de proton. Cela g\u00e9n\u00e8re un radical alkyle d'amine tertiaire r\u00e9actif centr\u00e9 sur C qui amorce la polym\u00e9risation et la r\u00e9ticulation des oligom\u00e8res et des diluants r\u00e9actifs. Les compos\u00e9s d'amine tertiaire comprennent les amines tertiaires aliphatiques, les amines tertiaires de type \u00e9thanolamine, les esters de benzoate de type amine tertiaire et les amines r\u00e9actives.<\/p>","protected":false},"excerpt":{"rendered":"
