Abstract
The invention discloses a photocuring pressure-sensitive adhesive tape and a preparation method thereof. The photocuring pressure-sensitive adhesive tape comprises a substrate, wherein the substrate is coated with a photocuring pressure-sensitive adhesive, and the photocuring pressure-sensitive adhesive comprises the following components: an acrylic ester curing agent, a diluent, a photoinitiator and an auxiliary agent. According to the photocuring pressure-sensitive adhesive tape and the preparation method thereof, provided by the invention, the substrate is coated with the photocuring pressure-sensitive adhesive, and the substrate is cured by optical radiation, the curing speed is fast, and the curing temperature is low, so that the production efficiency is improved; besides, no pollution is generated, and aging resistance and stability are high, so that the adhesive performance of the prepared pressure-sensitive adhesive tape is stable, and the pressure-sensitive adhesive tape can satisfy application requirements under different medical conditions.
Description
technical field [0001] The invention relates to an adhesive tape and a preparation method thereof, in particular to a photocurable pressure-sensitive adhesive tape and a preparation method thereof. Background technique [0002] Most of the currently used medical tapes are manufactured by solvent-based coating methods, emulsion-type coating methods, and hot-melt adhesive coating methods. The solvent-based coating method is to dissolve the adhesive in a solvent (such as gasoline, xylene, etc.), and then apply it to the anti-adhesive material (kraft paper, polyethylene film, silicone) after dissolution, and then dry it. The adhesive is transferred to the substrate by transfer coating to form a breathable patch. Due to the lightness and thinness of the selected substrate, usually the back of the substrate needs to be sizing first to block the pores and squeeze it flat, then apply organosilicon and fluorine substances to reduce the adhesion of the adhesive layer to the surface o...
