Masking tape containing printing layer and preparation method thereof

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 ...
