Embodiment 1
[0033] Example 1, the present invention includes the following components and raw materials in mass ratio: 25 parts of oligomer, 25 parts of diluent, 0.2 part of dispersant, 0.05 part of defoamer, 3 parts of initiator, 10 parts of pigment, 15 parts of filler , 1 part of solvent, 2 parts of anti-settling agent. In this embodiment, the oligomer is made by mixing aliphatic epoxy acrylate resin and aliphatic urethane acrylate resin, wherein the aliphatic epoxy acrylate resin is MR-2290, the aliphatic urethane acrylate resin is T95, and other Aliphatic epoxy acrylate resin and aliphatic urethane acrylate resin in the embodiment can also be replaced by other types of resins that can achieve the same effect. This system not only makes the ink coating itself possess excellent strength, and, due to the aliphatic modified The strong resin itself has low double bond content, and the high double bond conversion rate after reaction makes the ink coating have good stability in outdoor envir...
Embodiment 2
[0034] Example 2, the present invention includes the following components and raw materials in mass ratio: 30 parts of oligomers, 30 parts of diluents, 1.5 parts of dispersants, 0.2 parts of defoamers, 5 parts of initiators, 15 parts of pigments, and 20 parts of fillers , 4 parts of solvent, 6 parts of anti-settling agent.
[0035] In this embodiment, the oligomer is formed by mixing aliphatic epoxy acrylate resin and aliphatic urethane acrylate resin, wherein the aliphatic epoxy acrylate resin is 6109D, and the aliphatic urethane acrylate resin is T100. Other examples The medium aliphatic epoxy acrylate resin and aliphatic urethane acrylate resin can also be replaced by other types of resins that can achieve the same effect. This system not only makes the ink coating itself have excellent strength, but also, due to the aliphatic modified The double bond content of the resin itself is low, and the high double bond conversion rate after the reaction makes the ink coating have g...
Embodiment 3
[0036]Embodiment 3, the present invention comprises the following components and the raw material of mass ratio: 27 parts of oligomers, 27 parts of diluents, 0.8 parts of dispersants, 0.1 parts of defoamers, 4 parts of initiators, 13 parts of pigments, 17 parts of fillers , 2 parts of solvent, 4 parts of anti-settling agent. In this example, the oligomer is made by mixing aliphatic epoxy acrylate resin and aliphatic urethane acrylate resin, wherein the aliphatic epoxy acrylate resin is MR-2290, the aliphatic urethane acrylate resin is T100, and other Aliphatic epoxy acrylate resin and aliphatic urethane acrylate resin in the embodiment can also be replaced by other types of resins that can achieve the same effect. This system not only makes the ink coating itself possess excellent strength, and, due to the aliphatic modified The strong resin itself has low double bond content, and the high double bond conversion rate after reaction makes the ink coating have good stability in ...
