Printing ink for identifying electronic component by curing with ultraviolet light and preparation method thereof

Abstract

The invention discloses printing ink for identifying an electronic component by solidifying with ultraviolet light. The printing ink comprises the following components, by mass, 36-50% of a light curing oligomer, 0-10% of an adhesion reinforced resin, 6-10% of an ultraviolet light initiator, 10-30% of an active diluent, 5-30% of a pigment, 2-11% of a filler, 0.2-1% of a leveling agent, and 0.3-2% of a wetting dispersant. A preparation method of the printing ink comprises the following steps: 1, premixing the ultraviolet light initiator with the active diluent, controlling the temperature at 30-40DEG C, and stirring them to form a transparent liquid; 2, adding the mixed resin, the pigment, and above assistants, dispersing them by a high speed mixer, adding the filler, continuously stirring at a high speed to uniformity, and carrying out three-roll grinding to required fineness to obtain the printing ink. The printing ink for identifying the electronic component by curing with the ultraviolet light of the invention can be widely applied to the character identification of various electronic components, and has the advantages of clear writing, and excellent adhesion and solvent resistance.

Description

technical field [0001] The invention relates to an ink, in particular to an ultraviolet light curing electronic component marking ink and a preparation method thereof. Background technique [0002] Electronic technology is an emerging technology developed at the end of the nineteenth century and the beginning of the twentieth century. It developed the fastest and was most widely used in the twentieth century, becoming an important symbol of the development of modern science and technology. Character inks for signs have also been developed along with the development of electronic technology. Traditional solvent-based inks need to be air-dried, infrared-dried, or even dried naturally after printing. The drying time required ranges from a few minutes to a few days, and the production efficiency is low. Due to the slow drying, problems such as smearing and word drop are prone to occur during the printing process, resulting in a decline in printing quality. These all restrict t...
