Staining-resisting UV (Ultraviolet) coating as well as preparation method and application technology thereof

Abstract

The invention belongs to the field of coating and relates to staining-resisting UV (Ultraviolet) coating as well as a preparation method and an application technology thereof. The staining-resisting UV coating is prepared from the following components in percentage by weight: 50 to 60 weight percent of fluorosilicon modified acrylate, 10 to 15 weight percent of dipentaerythritol hexaacrylate, 10 to 15 weight percent of propoxylated pentaerythitol tetraacrylate, 3 to 5 weight percent of 1-hydroxyl-cyclohexyl-phenyl ketone, 2 to 5 weight percent of (2,4,6-trimethylbenzoyl)diphenyl phosphine oxide, 0.2 to 1 weight percent of a de-foaming agent, 0.2 to 1 weight percent of a flatting agent and 5 to 15 weight percent of a diluting agent, wherein the diluting agent is a mixture of absolute ethylalcohol and dicarboxylate. Compared with the prior art, the staining-resisting UV coating provided by the invention has high reaction activity and a rapid curing speed and the coating has a low shrinkage rate; and a formed coating film has a strong attachment force and excellent flexibility and is continuous and stable.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a stain-resistant UV coating, a preparation method and an application process thereof. technical background [0002] Since the first use of UV curing technology in Germany in the 1960s, UV curing technology has played an important role in many fields. UV-curable coatings have developed rapidly in the past half a century, and have been widely used in many fields, such as wood, metal decoration, printing industry, optical fiber coating, leather dawning, etc. Compared with traditional coatings, UV-curable coatings do not contain any organic solvents or inert diluents, do not require heating during curing, and have the characteristics of less environmental pollution, low energy consumption, and high production efficiency. [0003] On the other hand, people have also improved the technology of UV-curable coatings, and the coating film formed by the coatings has excellent stain resistance and ...

Problems solved by technology

[0004] However, this improved UV-curable coating also has some shortcomings. It has high requirements on curing conditions. If the curing conditions do not meet expectations, not only will the curing speed be reduced, but also the quality and effect of curing and production efficiency will be reduced. will be seriously affected

In the prior art, the use of increasing the functionality of the monomers in the UV-curable coating can speed up the curing speed of the system, but at the same time it will also increase the shrinkage of the coating, thereby reducing the adhesion of the coating film.
