Problems solved by technology

Among them, Darocur 1173 is liquid at room temperature, and the production cost is low; while Irgacure 184 is solid at room temperature, the production cost is high, and the risk of environmental pollution is relatively significant
At the same time, Irgacure 184 will be cracked during the photoinitiation process to produce a series of harmful and bad residual smell chemicals, including carcinogenic substances benzene, benzaldehyde, and cyclohexanone, etc., resulting in odor problems that are not pleasing to the environment and the health of users and VOCs pollution release (ie Volatile Organic Compounds)

Embodiment

[0021] Containing ethylenic bond (acrylate) UV radiation curable material formulation system samples are produced according to the following formula (by weight): bisphenol A epoxy acrylate (Ebecryl 605): 32%; amino acrylate (Ebecryl 7100): 10% ; Acryloylmorpholine: 54%; Photoinitiator: 4%.

[0022] Evaluation of photocuring performance: the above-mentioned examples and comparative samples are coated on cardboard to form a coating of about 20-25 microns, with a UV high-pressure mercury lamp (about 20 cm away from the substrate) as the irradiation light source, and the variable speed conveyor belt test . The criterion for the completion of photopolymerization curing is that the fingernail does not produce imprints after repeated pressing and scratching.

[0023]Evaluation of residual odor after curing: The residual odor of the film after curing is tested by 5 people independently evaluating the odor level, and the evaluation standards are marked as follows: Level 0: no odor; Le...

Abstract

The present invention relates to the field of photocuring (UV-Curing) new material chemicals, and in particular relates to a novel photoinitiator mixture, application of the photoinitiator mixture asa photoinitiator in an ethylenic-bond-containing unsaturated radiation-polymerizable system, and an ethylenic-bond-containing unsaturated radiation-polymerizable system containing a component of the photoinitiator mixture.

Description

【Technical field】 [0001] The invention relates to the field of photocuring (UV-Curing) new material chemicals, in particular to a novel photoinitiator mixture, its use as a photoinitiator in an ethylenically unsaturated radiation-polymerizable system, and the photoinitiator containing this photoinitiator Radiation polymerizable system containing ethylenic unsaturation as a component of an initiator mixture. 【Background technique】 [0002] In the technical field of photocuring new materials, photoinitiator (Photo-initiator) is the key material that absorbs the energy of UV radiation light source to generate active free radicals or cationic acid and other polymerization initiating species. Therefore, there is a continuous technical demand in the industry, namely The development and industrialization of new photoinitiator substances can meet various application demands such as performance improvement, low-cost economic competitiveness, convenient use, and environmental and heal...
