Abstract

The invention provides a quick-drying adhesive for a BOPP adhesive tape and a preparation method thereof. The preparation method includes: (1) dissolving sodium dodecyl sulfate and hexadecane with 1 / 2weight part of deionized water, then adding butyl acrylate, hydroxyethyl acrylate and vinyl acetate, and performing mixing and stirring to obtain a pre-emulsion; (2) dissolving alkylphenol polyoxyethylene and ammonium persulfate with residual water, placing the mixture in a reaction kettle and performing heating, then adding 1 / 2 weight part of the pre-emulsion dropwise into the reaction kettle for reaction; (3) adding p-tert-butyl phenolic resin, allyl modified alkyl phenolic resin, barium sulfate and tung oil into the remaining pre-emulsion, mixing the substances evenly, and then adding themixture dropwise into the reaction kettle; and (4) at the end of adding in a dropwise manner, performing natural cooling, adding tert-butyl hydroperoxide, then adding sodium formaldehyde sulfoxylate,and finally using ammonia water to adjust the pH to 6-7, thus obtaining the quick-drying adhesive for BOPP. The quick-drying adhesive for a BOPP adhesive tape provided by the invention has the characteristics of good film-forming properties and fast drying speed.

Description

technical field [0001] The invention relates to the field of quick-drying adhesives, in particular to an instant-drying adhesive for BOPP adhesive tape and a preparation method thereof. Background technique [0002] Sealing tape is also called BOPP tape, packaging tape, etc. It is based on BOPP biaxially oriented polypropylene film, and is evenly coated with pressure-sensitive adhesive emulsion after heating to form a glue layer ranging from 8 μm to 28 μm. It is an indispensable product in the life of light industry enterprises, companies and individuals. Pressure-sensitive adhesive is a special type of adhesive, once it is pasted or applied to the surface to be bonded, without solvent or heat, the adherend can be removed by pressing gently with fingers or other tools. Glue it up. In the past, pressure-sensitive adhesives were mainly solvent-based. In recent years, emulsion-type pressure-sensitive adhesives have developed rapidly, accounting for more than 60% of the total,...
