High-fidelity durable lightfast UV/UVLED curing coating for note and preparation method thereof

[0056] The mass percentage composition of coating is as follows:

[0057]

[0058] First, weigh aliphatic modified epoxy diacrylate resin, aliphatic polyurethane diacrylate, α, α-dialkylacetophenone DEAP, α-hydroxyalkylphenone 150, p-hydroxyanisole according to the above mass percentage , nano-calcium carbonate, add in the reaction vessel and stir, then roll on a three-roller machine to obtain a base material with a fineness≤15 μm, then weigh cyclotrimethylolpropane acrylate, 4(ethoxylated ) pentaerythritol tetraacrylate, trimethylolpropane triacrylate, and amine accelerator EDB are added to the base material, mixed with the base material, stirred with a high-speed mixer, and the stirring speed is 400 to 1500 rpm, stirring 20 to 60 Minutes, filtered to obtain the target coating with the appearance of a milky white uniform emulsion, the viscosity of the coating was measured to be 200-800mps / 25°C.

[0060]

[0061] First, weigh aliphatic polyurethane nonaacrylate, aliphatic polyurethane tetraacrylate, aliphatic polyurethane triacrylate, α-aminophenones 369, benzophenones CMBB, acyl phosphorus oxides 110, 2 , 6-tert-butylphenol, and polytetrafluoroethylene-modified polyethylene micropowder wax are added to the reaction vessel and stirred, then rolled on a three-roll machine to obtain a base material with a fineness of ≤15 μm, and then weigh the ring according to the above mass percentage. Trimethylolpropane acrylate, dipropylene glycol diacrylate, 4 (ethoxylated) pentaerythritol tetraacrylate, amine accelerator DMB are added in the base material, mixed with the base material, stirred with a high-speed mixer, and the stirring speed is 400-1500 rev / min, stirring for 20-60 minutes, and filtering to obtain the target paint with the appearance of a milky white uniform emulsion. The measured viscosity of the paint is 200-800mps / 25°C.

[0063] The mass percentage composition of coating is as follows:

[0064]

[0065] First, weigh modified polyurethane diacrylate, aliphatic polyurethane nonaacrylate, aliphatic polyurethane tetraacrylate, benzophenone PBZ, α,α-dialkylacetophenone 2959, acyl oxide Phosphorous TPO-L, p-hydroxyanisole, and white carbon black are added into the reaction vessel and stirred, then rolled on a three-roll machine to obtain a base material with a fineness of ≤15 μm, and then weigh tripropylene glycol according to the above mass percentage Diacrylate, 4 (ethoxylated) pentaerythritol tetraacrylate, trimethylolpropane tetraacrylate, and amine accelerator PDA are added to the base material, mixed with the base material, and stirred with a high-speed mixer at a stirring speed of 400-1500 rpm, stirred for 20-60 minutes, and filtered to obtain the target paint with the appearance of a milky white uniform emulsion. The measured viscosity of the paint is 200-800mps / 25°C.
