Electrolyte-resistant solvent type acrylate pressure-sensitive adhesive and method for preparing same

Abstract

The invention relates to the technical field of pressure-sensitive adhesive, in particular to electrolyte-resistant solvent type acrylate pressure-sensitive adhesive and a method for preparing the same. The electrolyte-resistant solvent type acrylate pressure-sensitive adhesive comprises, by weight, 15-18 parts of iso-octyl acrylate, 5-7 parts of butyl acrylate, 2-4 parts of acrylic acid, 7-10 parts of methyl acrylate, 4-6 parts of natural rubber, 3-5 parts of C9 tackifying resin, 50-150 parts of solvents, 0.3-0.6 part of initiators and 0.3-0.5 part of cross-linking agents. The electrolyte-resistant solvent type acrylate pressure-sensitive adhesive and the method have the advantages that acrylate monomers, the natural rubber with double bonds and the tackifying resin with double bonds areused as main bodies of the electrolyte-resistant solvent type acrylate pressure-sensitive adhesive, the ester, ketone and aromatic solvents are used as dispersion of the electrolyte-resistant solventtype acrylate pressure-sensitive adhesive, appropriate quantities of initiators and cross-linking agents are added into the dispersion and the main bodies, and accordingly the electrolyte-resistant solvent type acrylate pressure-sensitive adhesive which is high in adhesion property for aluminum materials and polypropylene films and is excellent in electrolyte resistance can be prepared by the aidof the method.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to an electrolyte-resistant solvent-type acrylate pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Acrylic pressure-sensitive adhesives are a type of adhesives that are widely used and are developing very rapidly. Solvent-type acrylate pressure-sensitive adhesive is an important branch of resin-type pressure-sensitive adhesives. Solvent-type acrylate pressure-sensitive adhesive has a low average relative molecular weight, and has excellent pressure sensitivity, adhesion, oxidation resistance, light resistance and Due to its aging resistance and other advantages, it has been widely used in the production of medical tapes, pressure-sensitive adhesive labels, BOPP packaging tapes, double-sided tapes, explosion-proof tapes, etc. [0003] However, acrylate pressure-sensitive adhesives also have disadvantages, such as poor t...

Problems solved by technology

[0003] However, acrylate pressure-sensitive adhesives also have disadvantages, such as poor temperature resistance, poor electrolyte resistance, and large differences in bonding performance to different types of adherends. It is necessary to introduce other materials to modify pressure-sensitive adhesives. improve its performance

Aluminum shell and polypropylene film are two different types of materials. Acrylic pressure-sensitive adhesives currently on the market cannot achieve high adhesion to aluminum and polypropylene film at the same time, and have good electrolyte resistance
