preparation example Construction

[0043] The preparation method of the TPU material screen printing ink is as follows: mix PU resin, ketone solvents, benzene solvents, and additives evenly, stir at high speed until completely dissolved, and then filter through 200-mesh gauze to obtain the finished product.

[0044] The TPU material screen printing ink, by weight percentage, can also include the following components:

[0045] Pigment 10-20.

[0046] Described TPU material screen printing ink, wherein, by weight percentage, is most preferably made up of following components:

[0047] PU resin 35;

[0048] Pigment 10;

[0049] Ketone solvents 36;

[0050] Benzene solvent 15;

[0051] Auxiliary 4.

[0052] The preparation method of the TPU material screen printing ink is as follows: PU resin, ketone solvent, and benzene solvent are fully mixed and then stirred evenly at high speed, then adding additives and pigments, grinding 5 times by a three-roller machine, and stirring evenly at high speed.

Abstract

The invention discloses silk-screen printing ink and an application thereof. The silk-screen printing ink is applied to thermoplastic polyurethane (TPU) calendaring molding. The silk-screen printing ink comprises the following components in percentage by weight: 30 to 40 percent of polyurethane (PU) resin, 30 to 45 percent of ketone solvent, 10 to 25 percent of benzene solvent and 1 to 5 percent of aid. According to the silk-screen printing ink for calendaring molding of the TPU material, the problems of light leakage, breakage and degumming after the conventional printing oil is printed and molded on the TPU are effectively solved. The silk-screen printing ink mainly comprises the PU resin and a proper amount of aids, so that the silk-screen printing ink has excellent using performance, can achieve the effects of good leveling and excellent adhesive force on the printing surface of the TPU material, and can meet the requirements of clients on wear resistance, high temperature resistance, punching resistance and the like of products.

Description

technical field [0001] The invention relates to the field of inks, in particular to a screen printing ink and its application. Background technique [0002] With the improvement of people's living standards, daily necessities are rich and colorful. For example, many touch buttons are originally made of hard materials, which have a bad hand feel. Therefore, many of the existing soft touch buttons are mostly made of TPU (thermoplastic polyurethane) materials. Add curing agent to printing ink to meet performance requirements such as bright light, stamping resistance, wear resistance, and high temperature resistance. However, after the existing ink is printed on the TPU material and then calendered with silica gel, there will be problems such as light leakage, breakage, and degumming. [0003] Therefore, the prior art needs to be perfected and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the presen...
