Abstract

The invention relates to an environment-friendly medical polyacrylate pressure-sensitive adhesive. The pressure-sensitive adhesive is prepared from a soft monomer, a hard monomer, a functional monomer, tackifying resin, an initiator, a compound containing epoxy groups and solvent, wherein the glass-transition temperature of the soft monomer is minus 65 DEG C-70 DEG C. The soft monomer can be ethyl acrylate, or butyl acrylate, or iso-octyl acrylate, or 2-ethylhexyl acrylate or the like, the hard monomer can be methyl methacrylate, or methyl acrylate, or phenylethylene, or vinyl acetate, or acrylonitrile or the like, the compound containing epoxy groups can be epoxypropane, or epoxybutane, or diphenol propane epoxy resin, or tetraphenol epoxy resin, or naphthol linetype novolac epoxy, or vinylcyclohexene dioxide epoxy resin or the like, and the solvent can be ethyl acetate, or normal hexane, or heptane, or methyl alcohol, or isopropanol, or butanone or the like. The pressure-sensitive adhesive can be used in the medical and health field.

Description

technical field [0001] The invention relates to a medical pressure-sensitive adhesive, which belongs to the field of polymer materials. Background technique [0002] Pressure-sensitive adhesive is a kind of adhesive that can be bonded to the adherend under the light pressure of external force. With its unique performance and characteristics, it has become the product with the largest amount of use and the widest application range among adhesives. Its products are almost found in various fields such as packaging, automobiles, transportation, communications, electrical appliances, building materials, machinery, aviation, light industry, and hygiene. . Among them, polyacrylate pressure-sensitive adhesives are relatively cheap due to their simple formula, wide bonding range, good weather resistance, strong light resistance, excellent oil resistance, good water resistance, no phase separation and migration, and convenient operation. For reasons such as pressure-sensitive adhesi...
