preparation example Construction

[0012] The preparation method of magenta silver paste ink of the present invention, comprises the steps:

[0013] Step 1: Add raw aluminum powder and solvent into a large beaker at the same time, stir with a magnetic stirrer at room temperature for a period of time, let it stand, then vacuum filter, and vacuum dry at 50°C to obtain pretreated aluminum powder;

[0014] The specifications of the raw material aluminum powder are 1000-1300 mesh,

[0015] The first solvent is absolute ethanol, distilled water or acetone, the ratio of aluminum powder (g): solvent (ml) is 1g: 5ml ~ 1g: 10ml, the stirring time is 2h ~ 3h, and the drying time is 2h ~ 3h.

[0016] Step 2, after mixing the pretreated aluminum powder, magenta pigment and solvent two, add them to a four-necked flask equipped with a precision booster electric stirrer and a reflux condenser, and place the flask in an electric heating constant temperature water bath Stirring under the protection of inert gas;

[0017] The ...

Embodiment 1

[0032] Magenta silver paste ink preparation method steps are as follows:

[0033] Step 1. Weigh 50g of raw aluminum powder (1000 mesh) and 250ml of absolute ethanol into a beaker, stir with a magnetic stirrer at room temperature for 2h, then let stand for 2h; then vacuum filter and dry in vacuum at 50°C 2h, obtain the pretreated aluminum powder;

[0034] Step 2, add 2g of pretreated aluminum powder, 2g of magenta pigment Cibacron Red4G-E and 20ml of absolute ethanol into a four-necked flask, and stir at room temperature for 1 hour under nitrogen protection to disperse the aluminum powder and magenta pigment evenly;

[0035] Step 3, warm up the water bath to 40°C, add 2ml orthosilicate methyl ester diluted with 10ml of absolute ethanol (liquid A) and 5ml of distilled water diluted with 10ml of absolute ethanol, 2ml of ammonia water, 2ml of vinyltrimethoxysilane (solution B) respectively. liquid), control the dropping rate to 1 drop / second, and the dropwise addition is complete...

Abstract

The invention discloses a preparation method of magenta silver paste printing ink, comprises the following steps: step one, magnetically stirring raw material aluminum powder and a first solvent, standing, filtering in vacuum, and drying in vacuum; step two, mixing the pre-treated aluminum powder, magenta pigment and a second solvent, and then feeding into a four-neck flask, stirring in a water bath pot; step three, configuring silicate ester diluted by the anhydrous ethyl alcohol, and a catalyst diluted by the anhydrous ethyl alcohol, distilled water and a silane coupling agent, respectively adding two configuration solutions in a separating funnel, continuously stirring after finishing the dropwise adding, filtering in vacuum, washing a product, drying in the vacuum to obtain the magenta modified aluminum powder; step four, dispersing the magenta modified aluminum powder by using distilled water, dispersing and adding resin and auxiliaries, manually stirring until the aluminum is uniformly dispersed in visual inspection to obtain the magenta silver paste printing ink. The magenta silver paste printing ink prepared by the method can completely meet the use requirement.

Description

technical field [0001] The invention belongs to the technical field of color silver paste ink, and relates to a preparation method of magenta silver paste ink. Background technique [0002] Due to the diversified development of economy and technology, in today's increasingly rich spiritual and cultural life, it has become a trend to pursue luxurious and high-end products with unique performance and green environmental protection. In recent years, various functional pigments that endow products with special effects have been highly valued, especially metallic pigment products—metallic inks, which have the high-gloss properties of metals and meet people's pursuit of high-end commodity packaging. With the increasing proportion of metallic ink printing on packaging and decoration printed matter, the demand for metallic ink printed matter continues to increase, and the research on multifunctional metallic ink products has never stopped. As a major branch of metallic ink, silver ...
