High wear-resistant and slippery transfer adhesive and preparation method thereof

Abstract

The invention provides a preparation method of a high wear-resistant smooth transfer adhesive and its coating. The high wear-resistant silky transfer adhesive includes the following components in parts by weight: high-functional polyurethane acrylate resin 40-60 , Low-official urethane acrylate resin 20-30, acrylate monomer 15-30, photoinitiator 2-10, modified wax powder 0.1-1.5, slip additive 0.1-1, solvent 4-10. The above-mentioned transfer adhesive is coated, baked, molded and solidified with a matte texture mold to form a coating with high wear resistance and silky feel. The transfer printing adhesive coating of the present invention is used for the surface protection of the plastic substrate of 3C products, has excellent wool felt friction resistance, and takes into account the silky feel at the same time, avoiding the method of directly embossing pure solid coatings with molds The problem of poor coating feel.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a preparation method of a high wear-resistant and smooth transfer adhesive and a coating thereof. Background technique [0002] UV-curable coatings have the advantages of fast curing, simple process, low energy consumption, and environmental friendliness. With the improvement of coating performance and the development of technology, the application of coatings is becoming more and more extensive. Transfer adhesive is a kind of UV-curable coating. It is used on PC, PET and PMMA substrates. It can be cured by mold embossing to reflect the effects of matte, brushed, CD lines, etc. It is often used in computers, mobile phones and household appliances. On the surface, it plays the role of texture transfer and surface protection, such as embossing matte texture on the touch panel of a laptop, which requires good wool felt wear resistance and silky feel. The matte effect makes the coating have ...

AI Technical Summary

Problems solved by technology

The matte effect makes the coating have a certain degree of haze, which not only reflects the high-end appearance effect, but also has a small frictional resistance because the microstructure of the coating is hemispherical, but the silky smoothness cannot be achieved by using ordinary transfer adhesives. Feel effect

In order to achieve a smooth feel effect, additives with a slippery effect are usually added. Too much additives will cause a decrease in the light transmittance of the coating due to the incompatibility of the additives. Too little additives will cause the It is difficult to migrate to the surface of the coating, resulting in poor slippery effect, and it is difficult to obtain a silky feel only by adding a single additive

[0003] In order to solve the problem of insufficient silky feel of coatings, those skilled in the art have proposed a variety of solutions, such as the invention in "A Pure Odor Wear-Resistant Silky UV Matt Finish Coating and Its Preparation Method", the publication number of which is CN 105505092A It is mentioned in the patent that the combination of modified silica and leveling agent can achieve the effect of clean odor, wear resistance and silkiness, but it is a self-dulling coating, and the light transmission of the coating is affected, which limits its application
