Embodiment 1-13

[0046] The preparation method of embodiment 1-13:

[0047] S1. Pre-dispersion: Weigh the diluent (epoxy resin, sodium dodecyl sulfonate and deionized water) according to the corresponding parts by weight, treat the diluent with ultrasonic waves for 10-15min, and then add the corresponding metal parts by weight Add slurry (gold paste or silver paste), adsorbent (nano-silicon dioxide or nano-titanium dioxide), dispersant (ethanol or isopropanol), titanate coupling agent and polysorbate-80 to the diluent, and then After ultrasonic treatment for 20-25min;

[0048] S2. Pre-mixing: put the ink base of the corresponding weight in a 280-400r / min stirrer and stir, slowly add the ultrasonically treated mixture in S1 while stirring, and stir at a speed of 450-500r / min after the addition is complete 30-35min;

[0049] S3. Packaging: put the final product obtained in S2 into a packaging drum.

[0050] The ink prepared according to Examples 1-13 has bright colors. Components and their w...

Abstract

The invention discloses ink, comprising 20-35 parts of ink base, 5-10 parts of adsorbent, 0.01-0.05 part of polysorbate-80, 20-30 parts of reducer, 5-10 parts of titanate coupling agent, 5-10 parts of dispersant, and 1-5 parts of metal paste. The metal paste is silver or gold paste, the ink base is at least one of green ink, yellow ink, golden red ink or deep blue ink. Polysorbate-80 forms a protective layer on the surface of metal powder and adsorbent to be attracted with adsorbent with the polar group. A great deal of adsorbent contacts and is combined with the surface of the metal powder. The titanate coupling agent is of long-chain structure, epoxy resin is of three-dimensional mesh structure, and the polysorbate-80, the titanate coupling agent and the epoxy resin are made up of a special brightness enhancement film after ultrasonic treatment. Therefore, ink brightness after added with metal powder is increase by more than 20%. The more stable structure is formed under the combined action of the epoxy and the titanate coupling agent, so that ink can be kept in bright color for a long time.

Description

technical field [0001] The invention relates to the technical field of ink printing, more specifically, it relates to an ink, a preparation method thereof, and a printing process using the ink. Background technique [0002] Printing is to transfer the ink to the surface of paper, fabric, leather and other materials through the processes of plate making, ink application and pressurization of originals such as text, pictures and photos. The technology of batch copying the content of original manuscripts, including book printing, news printing, advertising printing, banknote printing, map printing, stationery printing, special printing, etc., is inseparable from our daily life. [0003] With the improvement of living standards and the development of enterprises, ordinary ink printing has been unable to meet the needs of all customers. In order to meet the needs of various groups of people, including printing corporate brochures, calendars, personalized business cards, and some...
