Embodiment 1

[0023] 1. Preparation of mirror silver ink

[0024] Step 1, by the content of each component specified in Table 1, the following components: SiO 2 、Al 2 o 3 、Cr 2 o 3 , Ca 3 (PO 4 ) 2 、Na 2 SiF 6 Put it in an environment of 200-300°C and grind for X-Y minutes to form uniform inorganic mixed particles, and cool naturally to room temperature;

[0025] Step 2, pulverizing and grinding the cooled inorganic mixture particles into a powdered inorganic mixture with a particle size of 6 μm-10 μm;

[0026] Step 3. According to the content of each component specified in Table 1, add the following components: pigments, fillers, additives, and solvents to the powdered inorganic mixture, and stir evenly at 20-30°C, and then use The grinding process grinds into a fluid mixture with a particle size of 6 μm-10 μm, and the fluid mixture is mirror silver ink.

[0027] 2. Use and performance test of mirror silver ink

[0028] Step 1. Provide a plastic part (TV panel), silk screen fix...

Abstract

The invention discloses mirror silver ink and a preparation method thereof, wherein the mirror silver ink comprises following components in part by mass: 70-80 parts of inorganic composite material and 20-30 parts of organic high molecular material; the inorganic composite material comprises following components: 1.4-2.5 parts of SiO2, 20-30 parts of Al2O3, 24-38 parts of Cr2O3, 2-10 parts of Ca3 (PO4) and 3-5 parts of Na2SiF6; and the organic high molecular material comprises following components: 10-24 parts of pigment, 1.6-5 parts of filler, 0.25-1 part of assistant and 2.5-4 parts of solvent. In the mirror silver ink and the preparation method, provided by the invention, the mirror silver ink prepared by the preparation method can be directly silkscreened on the surface of a plastic part, so that the surface of the plastic part has effects of mirror surface, metallic feeling and strong silvery reflection.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a mirror silver ink and a preparation method thereof. Background technique [0002] At present, when the mirror silver ink on the market is screen-printed on the back of transparent materials (acrylic, PVC, glass), the directional arrangement of silver powder scales can be achieved. Due to the directional arrangement, the surface of the transparent material depends on the refraction of the material itself and the reflection of the surface to reflect the mirror surface. Metallic, silver reflective effect. However, if this mirror silver ink is printed on the surface of plastic parts, the surface of the plastic parts does not have a bright metallic feel, and this ink has low adhesion, is not wear-resistant, and is not resistant to high temperatures. [0003] In order to make the surface of the plastic parts achieve the effect of mirror surface, metallic feeling, and strong silver refl...
