Embodiment 1

[0054] Such as figure 1 As shown, mix 44 parts by weight of modified polyester resin, 33.7 parts by weight of ketone solvent, 20 parts by weight of benzene solvent and 2.3 parts by weight of additives, stir at high speed until completely dissolved, and then pass through 200 mesh The finished product of IMD calendering screen printing ink can be obtained through mesh filtration.

Embodiment 2

[0056] Such as figure 2 As shown, mix 45 parts by weight of modified polyester resin, 26.5 parts by weight of ketone solvent, 12 parts by weight of ester solvent and 1 part by weight of defoamer, mix well and stir evenly at high speed, then add 0.5 parts by weight Part of dispersant and 15 parts by weight of titanium dioxide are filtered through a 200-mesh gauze to obtain the finished IMD calendered screen printing ink.

[0057] Table 1 shows the printing effect and physical and chemical index status of the IMD calendering screen printing ink obtained in Example 1 and Example 2 on the material.

[0058]

Embodiment 3

[0060] Mix 50 parts by weight of modified polyester resin, 25 parts by weight of ketone solvent, 23 parts by weight of benzene solvent and 2 parts by weight of additives, stir at high speed until completely dissolved, and then filter through 200 mesh gauze Get the finished IMD calendering screen printing ink.

Abstract

The invention discloses IMD (In-Mold Decoration) calendaring silk-screen printing ink which comprises the following components in percentage by weight: 40-50% of modified polyester resin, 25-30% of ketone solvent, 20-25% of benzene solvent and 1-5% of assistant. The printing ink solves the problems that existing IMD calendaring is poor in draying effect and the printing process is too fussy. The printing time is reduced, and the extremely strong inner binding force is improved, so that the printing ink has excellent using performance and has the effects of good leveling performance and excellent adhesion force on the printing surfaces of PC (Poly Carbonate) and PET (Polyethylene Terephthalate) materials. The printing oil is bright in color and high-temperature resistance, and the demands of clients on high temperature resistance, high ductility, high adhesive force and high adhesion of products are met.

Description

technical field [0001] The invention relates to a calendering screen printing ink suitable for the technical field of injection molding decoration of PC and PET in-mold inserts, in particular to an IMD calendering screen printing ink. Background technique [0002] With the improvement of people's living standards, daily necessities are rich and colorful, and IMD (In-Mold Decoration: film decoration technology) technology products are widely used in many industries. IMD technology belongs to the application technology of injection molding surface materials, which combines traditional injection molding Technology and post-processing technology are combined to form one body. It breaks through the limitations of traditional plastic shell design, and can achieve "colorful", "texture", "three-dimensional color pattern" and other effects, and has the advantages of energy saving and environmental protection. Offset printing can achieve effects such as multi-color collision and mult...
