Problems solved by technology

However, in practical applications, the curved corners during transfer printing will cause cracking due to the high density of the coating space, the printability of the protective layer after UV curing is poor, and the adhesion to the ink is not good, and outdoor UV transfer The printing film also has disadvantages such as not being resistant to weather, not being resistant to yellowing, not being resistant to soaking water, and high cost, which will lead to aging, yellowing, and blistering after a period of use, which will affect its aesthetic effect and product quality

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.

Abstract

The invention discloses UV outdoor screen printing ink. The printing ink is prepared from, by mass, 25-30 parts of oligomer, 25-30 parts of diluent, 0.2-1.5 parts of dispersing agent, 0.05-0.2 part of defoaming agent, 3-5 parts of initiator, 10-15 parts of pigment, 15-20 parts of pigment, 1-4 parts of solvent and 2-6 parts of anti-settling agent. The invention further discloses a preparation technology of the UV outdoor screen printing ink. The UV outdoor screen printing ink has a high reaction double bond conversion, has little influence on performance of a coating and is good in stability after reaction, a printing ink coating has excellent stability, long service life, good fineness and good dispersity in the outdoor environment, and printing ink cost can be reduced. Meanwhile, influences on system performance are small, the ultraviolet absorbing range is wide, absorbing efficiency is high, energy is saved, good curing performance of the coating is guaranteed, and the printing ink has the advantages of being better in adhesion, weather resistance and boiling water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a UV outdoor screen printing ink and a preparation process thereof. Background technique [0002] With the development of society and the improvement of quality of life, people's requirements for decoration are no longer limited to beautiful patterns or bright colors, but more concerned about the quality and functionality of products. Outdoor transfer film is widely used because of its variety of patterns and texts, and it is suitable for various substrates. Transfer film refers to the decorative graphic with adhesive, which can be separated from the carrier film together with the protective layer under the action of heat or pressure, and firmly adhered to the surface of the transfer product. It is a printing film with special functions. The performance of the protective layer in the thermal transfer film is the core part of the thermal transfer technology, because aft...
