Problems solved by technology

However, the shells of electronic products are generally made of plastic, and a large amount of organic solvents must be used in the process of printing on plastics, and the use of a large amount of organic solvents causes problems in many inks used for paper printing, such as poor adhesion, drying Slow, poor gloss and leveling, easy to crack, easy to spread and pinhole phenomenon

Abstract

The invention provides white transparent ink for an electronic product. The white transparent ink comprises the following components in parts by weight: 5.9 parts of solvent, 5 parts of curing agent, 0.7 part of white ink, 80 parts of standard-viscosity colorless ink and 0.9 part of dull ink. Meanwhile, the invention provides a preparation method of the ink. The invention can provide the white transparent ink which is vivid in color; meanwhile, the ink is strong in adhesive force, rapid in drying, good in glossiness and leveling property, free of fracturing, not easy to diffuse and free of pinhole phenomenon. According to a preferred scheme, linseed oil is added into a solvent, and the characteristic that linseed oil is high in volatilization speed is sufficiently exerted, so that the ink is higher in drying speed and stronger in adhesive force.

Description

technical field [0001] The invention relates to the field of inks, in particular to a transparent white ink for electronic products and a preparation method thereof. Background technique [0002] Ink is mainly composed of colorants, binders, fillers, solvents and curing agents. The amount and type of colorants determine the color of the ink. [0003] With the improvement of people's living standards, the color requirements of inks are getting higher and higher, and they are no longer satisfied with simple solid colors, but pursue individual colors. At present, the ink used for paper has a variety of colors, which can basically meet people's needs. However, the ink used in electronic products does not have a very rich color selection. The appearance design of electronic products has become one of the important factors for consumers to choose products. For this reason, most manufacturers have tried their best to design the appearance of electronic products. Obviously, adding...
