Abstract

The invention relates to the technical field of printing ink, in particular to high light, wear resistant and aging resistant silica gel PU printing ink and a preparation method and application methodthereof. The high light, wear resistant and aging resistant silica gel PU printing ink prepared from polyester polyol resin, a curing agent, a PU coating modifier, a coupling agent, an an anti-UV (ultraviolet) aging agent and a diluting agent has the advantages of good light and excellent adhesion, wear resistance and aging resistance, and can pass through adhesion test, friction test, cold and hot shock test, cosmetic resistance test, hand perspiration test, UV aging test and light resistance test. The preparation method includes the steps of 1, weighing; 2, dispersing and mixing. The application method includes the steps of A, spraying; B, baking. The preparation method and the application method have the advantages of simple process and low production cost, and can be suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a high-gloss, wear-resistant and aging-resistant silicone PU ink, a preparation method and an application method thereof. Background technique [0002] At present, with the development of science and technology, the application of electronic products is becoming more and more extensive. In addition, as the demands of consumers continue to increase, consumers not only require the performance or functions of electronic products to meet their needs, but also have higher and higher requirements for the appearance of electronic products. [0003] For the surface of some silicone buttons, such as automotive silicone buttons, characters or patterns need to be printed on the surface. In the prior art, the ink brightness printed on the surface is not enough, and there are problems of poor adhesion, wear resistance and aging resistance. defect. Therefore, there is an urgent need to develop ...
