A kind of anti-static discharge high-brightness mirror ink and its preparation and use method

Abstract

The invention discloses anti-static discharge high-brightness mirror ink which comprises the following components in parts by weight: 80-90 parts of high-transparency resin, 10-20 parts of polyester resin, 0.3-0.6 part of aluminum powder, 4-22 parts of a hardener, 2-6 parts of additives and 0-20 parts of a solvent The invention also discloses preparation and use methods of the mirror ink, wherein the use method comprises steps of primary printing, secondary printing and silver embossing. The mirror ink provided by the invention adopts a novel formula in which the content of aluminum powder is reduced and a layered printing process is innovated, so that the printed products have high brightness and ESD resisting function, have no failure even if a human body operates a screen with static electricity, and have strong adhesion, high temperature and humidity resistance, high leveling, ultrasonic cleaning resistance, rich color and other excellent properties after being suffered to specific drying conditions.

Description

technical field [0001] The invention relates to the technical field of printing ink manufacture, in particular to an anti-static discharge high-brightness mirror ink and a method for preparing and using the same. Background technique [0002] In recent years, with the continuous advancement of science and technology and the continuous improvement of human living standards, people have higher and higher requirements for the decoration of daily necessities. In addition to requiring rich colors and three-dimensional effects on the decorative surface, the surface also requires a mirror effect. At present, mirror silver inks are used on the surface of PC (polycarbonate), PMMA (acrylic or plexiglass), hard PVC (polyvinyl chloride) and treated PET (polyester) glass. In particular, mirror silver on glass is widely used. Logos such as mobile phones, tablets, and electrical appliances are all printed with mirror silver to achieve a mirror-like effect!

Problems solved by technology

[0003] A variety of mirror inks have appeared on the market. However, most mirror inks have simple manufacturing processes, poor mirror effects, and low adhesion. After a period of time, the oil film is prone to peeling off. Friction generates charges during printing, and the charges continue to accumulate, which is very easy to generate static electricity and cannot be dissipated. With the accumulation of charges, it will cause a series of electrostatic faults, and problems such as high ink fluidity, poor printing adaptability, and easy to scatter oil. Affect use and aesthetics

[0004] Existing products mainly adopt traditional technology, formula and production process, that is, choose acrylic resin plus some leveling aids, defoamers, etc., and mix them uniformly with a disperser, which can only meet the conventional performance requirements. The disadvantages are: 1. Electrostatic mottle phenomenon, which mainly occurs when printing polyolefin film, forms some indeterminate patterns in large-area pattern parts; 2. Static burr phenomenon, a linear structure appears around the printed pattern; 3. Dust suction phenomenon, absorbing dust impurities in the air, dust spots appear on the printed pattern, reducing the printing quality of the ink
