Problems solved by technology

However, most of the medical acrylic pressure-sensitive adhesive products currently on the market are made of traditional acrylic solvent-based glue, and the thickness of the glue layer is mostly 30~50um. If the coating thickness of acrylic solvent-based glue is reduced, the adhesion will also decrease. The performance requirements of general medical adhesive products require at least 1kg / in of adhesive force. If traditional acrylic solvent-based glue is used, its adhesive force can only reach 500-800g / in; During the process, if the solvent is not dried, the remaining solvent will irritate the skin. Therefore, it is difficult for the existing acrylic solvent-based glue to meet the requirements of high adhesion and non-irritation. The above problems need to be solved urgently

Description

technical field [0001] The invention relates to the technical field of medical pressure-sensitive adhesives, in particular to an ultraviolet-cured solvent-free medical pressure-sensitive adhesive and a preparation process thereof. Background technique [0002] Pressure-sensitive adhesive products can be widely used in various industries such as printing, packaging, construction, medical treatment, electronics, automobiles and daily necessities, and play various bonding functions such as adhesion, fixing, protection, sealing, insulation and bundling. Traditionally in China, the first generation of medical pressure-sensitive adhesive products composed of natural rubber and resin has been around for a long time, and then evolved to use zinc oxide adhesive plaster to make medical pressure-sensitive adhesive products, but in recent years, synthetic rubber, organic The emergence of silicon and acrylate pressure-sensitive adhesives has gradually become the application material for ...
