Problems solved by technology

On the one hand, because the molecular chain of polypropylene (PP) materials does not contain polar polar groups, the surface energy is extremely low, and the general ink screen printing is used, and its adhesion is extremely poor. Many products that need to be printed are appearance parts and are not allowed to be used. The PP treatment agent treats the surface, so the surface energy of PP products cannot meet the requirements of printing. According to the data, the surface energy of at least 40 dynes can meet the requirements of printing adhesion, but the surface energy of common PP products is only 30 dyne left and right
On the other hand, the blanking density of injection molding products is not uniform during the injection molding process, and the products also have anisotropy. The same ink, the same screen and screen scraping, the former part is qualified, and the latter part may be Unqualified; In addition, during the printing process, the diluent is constantly volatile, and the viscosity of the ink is constantly changing, so it will also cause the thickness of the curing agent to vary.
The non-treatment inks on the market can not meet the adhesion requirements of customers

Abstract

The invention belongs to the technical field of ink and in particular relates to screen printing ink for a surface of a polypropylene material and a preparation method of the screen printing ink. Thescreen printing ink for the polypropylene material comprises the following components in parts by weight: 25-35 parts of polypropylene resin, 18-26 parts of a solvent, 16-24 parts of pigments, 0.3-0.8part of a dispersing agent, 0.3-0.8 part of a flatting agent and 20-30 parts of a filling agent. According to the screen printing ink disclosed by the invention, polypropylene products do not need tobe subjected to surface treatment before printing and can be directly printed, adverse effects of surface treatment agents, flaming machines and corona treatment on product appearances are avoided, the cost is saved, the ink adhesive force is high, the performance is stable, and the requirements of appearance products can be met.

Description

technical field [0001] The invention belongs to the technical field of inks, and in particular relates to a treatment-free screen printing ink used on the surface of polypropylene materials and a preparation method thereof. Background technique [0002] Printing is one of the important means to improve product appearance, convey product selling points, and product performance identification. It is low-cost and widely used. The printing of polypropylene (PP) products has always been a recognized problem in the industry. On the one hand, because the molecular chain of polypropylene (PP) materials does not contain polar polar groups, the surface energy is extremely low, and the general ink screen printing is used, and its adhesion is extremely poor. Many products that need to be printed are appearance parts and are not allowed to be used. The PP treatment agent treats the surface, so the surface energy of PP products cannot meet the requirements of printing. According to the d...
