Abstract

The invention discloses a method for preparing an ultraviolet light polymerization environment-friendly antibacterial acrylic ester medical pressure sensitive adhesive product. The method comprises the following steps of: (a), preparing an acrylic ester oligomer; (b), uniformly mixing protective colloid, a broad-spectrum antibacterial medicine, a polymer elastomer and the acrylic ester oligomer; and (c), dissolving the mixture mixed in the step (b) in a polymerizable monomer to obtain pressure sensitive adhesive cement capable of coating at normal temperature, coating the pressure sensitive adhesive cement on a base material, and performing ultraviolet light polymerization to obtain the medical pressure sensitive adhesive product. The medical pressure sensitive adhesive product is environment-friendly and antibacterial, has good adhesion property on skins, and can well absorb moisture and release sweat; when the pressure sensitive adhesive product is pasted and removed, a user does not feel pain, and residual adhesives are avoided; and the medical pressure sensitive adhesive product has good biocompatibility, does not irritate the skins, and can effectively prevent infection of wounds or surgical incision sites.

Description

Technical field: [0001] The invention relates to the technical field of production of medical pressure-sensitive adhesives and products thereof, in particular to a method for preparing ultraviolet-cured environmental-friendly antibacterial acrylate medical pressure-sensitive adhesive products. Background technique: [0002] Medical pressure-sensitive adhesives are widely used in the manufacture of pressure-sensitive adhesive products in the medical and health field and some medical composite materials. The application of ultraviolet (UV) light-curing acrylate pressure-sensitive adhesives in the medical and health field is a new trend and has good advantages. UV light-curing medical acrylate pressure-sensitive adhesive does not contain solvents and will not cause environmental pollution. It is an environmentally friendly pressure-sensitive adhesive; medical adhesive products coated with it have better adhesion to the skin. It can better absorb moisture and perspiration. It w...
