preparation example Construction

[0049] The preparation method of screen printing ink of the present invention, described preparation method comprises the steps:

[0050] 1) In parts by weight, add 25 to 30 parts of weak solvent into the stirring tank, add 20 to 25 parts of thermoplastic acrylic resin while stirring, stir until completely dissolved, and form a viscous and transparent resin liquid after cooling;

[0051] 2) Put the viscous transparent resin liquid obtained in step 1) in a stirring tank and stir, and add 0.1 to 0.3 parts of dispersant, 0.1 to 0.5 parts of organic bentonite, 0.3 to 1 part of fumed silica, 20-25 parts of titanium dioxide, stirred until evenly mixed, and then ground to obtain a transparent viscous ink intermediate;

[0052] 3) The transparent viscous ink intermediate obtained in step 2) is placed in a stirring tank and stirred, and 0.5 to 1 part of defoamer is added while stirring in parts by weight, and the screen printing ink is obtained after stirring evenly.

Embodiment 1

[0054] The preparation method of the screen printing ink of the present embodiment, comprises the steps:

[0055] 1) Under normal temperature and pressure, add 25 parts of tetramethylbenzene into the stirring tank by weight, add 25 parts of thermoplastic acrylic resin while stirring, stir at a stirring speed of 800r / min for 2 hours until it is completely dissolved, and form a viscous mixture after cooling. Thick transparent resin liquid;

[0056] 2) Under normal temperature and pressure, put the viscous transparent resin liquid obtained in step 1) into a stirring tank and stir, and in parts by weight, add 0.1 part of Lubrizol hyperdispersant, 0.5 part of Organic bentonite, 0.5 parts of fumed silica, 20 parts of rutile titanium dioxide, stirred at a stirring speed of 600r / min for 20 minutes until uniformly mixed, and then ground by a three-roller machine to obtain a transparent viscous ink intermediate;

[0057] 3) Under normal temperature and pressure, place the transparent v...

Embodiment 2

[0059] The preparation method of the screen printing ink of the present embodiment, comprises the steps:

[0060] 1) Under normal temperature and pressure, add 28 parts of tetramethylbenzene into the stirring tank in parts by weight, add 22 parts of thermoplastic acrylic resin while stirring, stir at a stirring speed of 900r / min for 1.6h until it is completely dissolved, and form after cooling Viscous transparent resin liquid;

[0061] 2) Under normal temperature and pressure, put the viscous transparent resin liquid obtained in step 1) into a stirring tank and stir, and in parts by weight, add 0.2 parts of Lubrizol hyperdispersant, 0.4 parts of Organic bentonite, 0.7 parts of fumed silica, 22 parts of rutile titanium dioxide, stirred at a stirring speed of 700r / min for 16 minutes until uniformly mixed, and then ground by a three-roller machine to obtain a transparent viscous ink intermediate;

[0062] 3) Under normal temperature and pressure, place the transparent viscous in...

Abstract

The invention provides silk-screen printing ink and a preparation method thereof. The silk-screen printing ink is prepared from the following ingredients in parts by weight: 20 to 25 parts of thermoplastic acrylic resin, 25 to 30 parts of weak solvents, 0.1 to 0.3 part of dispersing agents, 0.5 to 1 part of anti-foaming agents, 0.1 to 0.5 part of organobentonite, 0.3 to 1 part of fumed silica and20 to 25 parts of titanium dioxide. The silk-screen printing ink prepared by the preparation method of the silk-screen printing ink has the advantages that the printing performance is good; the attachment force is high; during the printing on an acrylic material, the erosion on an acrylic substrate cannot occur; the generation of phenomena such as stress cracking and lifting floating is avoided. The silk-screen printing ink is particularly applicable to acrylic materials; the problems that general acrylic silk-screen printing ink can easily erode the substrate, is difficult to match with the ink with the mirror surface effect to be used, or is lack of printing applicability due to too high drying speed can be solved.

Description

technical field [0001] The invention belongs to the technical field of screen printing ink, and relates to a screen printing ink and a preparation method thereof. Background technique [0002] Acrylic, also known as PMMA or plexiglass, and its chemical name is polymethyl methacrylate, is an important plastic polymer material developed earlier. Acrylic has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance. Transparent acrylic sheet has a light transmittance comparable to glass, but its density is only half that of glass. In addition, it is not as fragile as glass, and even if it is broken, it will not form sharp fragments like glass. In addition, it is cheap, easy to process, simple in manufacturing process, and low in cost. Therefore, acrylic materials are widely used in electronic products, instrumentation parts, automotive lights, optical lenses, and construction industries. [0003] The acrylic board has good pr...
