Emulsion pressure-sensitive adhesive for protecting adhesive tape and preparation method thereof

Abstract

The invention provides an emulsion pressure-sensitive adhesive for protecting an adhesive tape and a preparation method thereof. The emulsion pressure-sensitive adhesive is prepared from butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, styrene, crylic acid, hydroxy-propyl acrylate, an initiator, a buffer agent and an emulsifier in a polymerization manner. The preparation method of the emulsion pressure-sensitive adhesive comprises the following steps: a) selecting a synthetic material; b) preparing pre-emulsion; c) performing polymerizing emulsion; d) detecting a product. The invention discloses the emulsion pressure-sensitive adhesive for protecting the adhesive tape and the preparation method thereof. The emulsion pressure-sensitive adhesive is advanced in preparation technology, and simple in preparation process; the prepared emulsion pressure-sensitive adhesive not only has strong initial tension and high peel strength, but also has good high-temperature, high-humidity and aging resistance, and high application value.

Description

technical field [0001] The invention relates to a protective tape, in particular to an emulsion pressure-sensitive adhesive used for protecting the tape and a preparation method thereof, belonging to the technical field of tapes. Background technique [0002] Protective film tape is a film-like material that has a protective function for other materials. It is usually made of polyolefin plastic film or kraft paper, with rubber or acrylic resin as pressure-sensitive adhesive, and processed by a coating machine. A high-quality protective film tape must have the following characteristics: 1) It has suitable adhesion for different protected surfaces. In the process of material handling and processing, the protective film does not warp or fall off, and there is no pressure-sensitive adhesive residue when the protective film is peeled off; 2) It has good weather resistance, and the peeling strength does not change much after a few days or a long period of time. 3) It is inert to ...

AI Technical Summary

Problems solved by technology

[0003] In the current technology, the vast majority of protective film tapes use solvent-based acrylate pressure-sensitive adhesives in consideration of environmental protection, resource conservation, and cost reduction, but most of them are limited to medium and low peel strength acrylate emulsion pressure-sensitive adhesives, and Emulsion pressure-sensitive adhesive has strong water absorption, but poor high-temperature and high-humidity aging performance

At present, although some emulsion pressure sensitive adhesives developed by people have strong peel strength and initial tack, they have poor high temperature and high humidity aging resistance; although some emulsion pressure sensitive adhesives have good high temperature and high humidity aging resistance, their peel strength and initial adhesion The viscosity is not high; although some emulsion pressure-sensitive adhesives have good initial viscosity and high temperature and high humidity aging resistance, the peel strength is not high
