Problems solved by technology

According to the traditional process, simply and directly printing or coating advertising information on the general masking tape, not only the effect is poor, but also has a significant impact on the performance of the product
[0003] Compared with traditional solvent rubber pressure sensitive adhesives, solvent rubber pressure sensitive adhesives are flammable, toxic, and have relatively high initial performance, but with time and climate change, the performance declines rapidly, generally after 120 days will fail

Embodiment 1

[0037] A preparation method of a masking tape containing a printing layer, comprising the following steps:

[0038] Step (1): Add 45g / m 2 Base paper impregnated with hydroxybutadiene emulsion with a solid content of 25%, and the impregnation amount is 9.5g / m 2 (dry weight), heated at 118°C for 60 seconds and dried, then placed at room temperature for 24 hours to obtain the substrate;

[0039] Step (2): Perform monochrome "roller printing" of water-based ink on the substrate obtained in step (1) with an anilox roller with engraved patterns;

[0040] Step (3): Apply a water-based polyvinyl acetate-based release agent with a solid content of 18% to the printed substrate in step (2), and the coating amount is 3.5g / m 2 (dry quantity); heat at 140°C for 24 seconds, dry and place at room temperature for 48 hours;

[0041] Step (4): Coat the water-based acrylate pressure-sensitive adhesive with a solid content of 45% on the substrate treated in step (3), and the coating amount is 2...

Embodiment 2

[0045] A preparation method of a masking tape containing a printing layer, comprising the following steps:

[0047] Step (2): Perform 3-color "roller printing" of water-based ink on the substrate obtained in step (1) with 3 sets of anilox rollers with engraved patterns;

[0048] Step (3): Apply a water-based polyvinyl acetate-based release agent with a solid content of 22% to the printed substrate in step (2), and the coating amount is 4.8g / m 2 (dry weight); heat at 118°C for 28 seconds, dry and place at room temperature for 48 hours;

[0049] Step (4): Coat the water-based acrylate pressure-sensitive adhesive with a solid content of 50% on the substrate treated in step (3), and the coating amount is 35g / m 2 (dry ...

Embodiment 3

[0053] A preparation method of a masking tape containing a printing layer, comprising the following steps:

[0054] Step (1): add 50g / m 2 The base paper is impregnated with hydroxy-butadiene styrene emulsion with a solid content of 25%, the impregnation amount is 12g / ㎡ (dry weight), heated at 125°C for 70 seconds and dried, then placed at room temperature for 24 hours to obtain the substrate;

[0055] Step (2): Perform single-color "jet printing" of water-based ink on the substrate obtained in step (1) with an electronically controlled inkjet device;

[0056] Step (3): Apply a water-based polyvinyl acetate-based release agent with a solid content of 25% to the printed substrate in step (2), and the coating amount is 6.8g / m 2 (dry quantity); heat at 125°C for 20 seconds, dry and place at room temperature for 48 hours;

[0057] Step (4): Apply a water-based acrylate pressure-sensitive adhesive with a solid content of 56% to the substrate treated in step (3), and the coating am...

Abstract

The invention discloses a masking tape containing a printing layer and a preparation method thereof. The masking tape comprises a substrate, wherein one side of the substrate is provided with an adhesive layer, and the other side of the substrate is sequentially provided with a printing layer and a release layer; the substrate is masking tape base paper impregnated by a hydroxy butadiene-styrene emulsion; the printing layer is a water-based ink; the adhesive layer is a water-based acrylate pressure-sensitive adhesive; and the release layer is a water-based release agent. All the raw materials are water-based materials, and thus, the production technique is environment-friendly; and the product has the advantages of stable performance, long shelf life, low production cost and high added value.

Description

technical field [0001] The invention belongs to the field of masking tapes for industrial masking and protection, and in particular relates to a masking tape containing a printing layer and a preparation method thereof. Background technique [0002] Masking tape is an auxiliary material often used in the electronics industry and architectural decoration industry. Its main function is shielding protection and temporary fixation. The production process of traditional masking tape is to apply a release agent on one side and an adhesive on the other side on ordinary impregnated paper (the base paper has been impregnated), without any advertising information attached. This is because of the particularity of the base paper of the masking paper, impregnating agent, release agent and adhesive. It is much more difficult to print or coat advertising information on the masking tape than "BOPP sealing tape". According to the traditional process, simply and directly printing or coating ...
