Embodiment

[0053] 1. Preparation of acrylate resin

[0054] Part of the soft monomer, part of the hard monomer, part of the functional monomer and part of the initiator are mixed according to a certain ratio and fully dissolved to obtain a first mixed solution.

[0055] The remaining part of the soft monomer, the remaining part of the hard monomer, the remaining part of the functional monomer, the remaining part of the initiator and the second solvent are mixed according to a certain ratio, and fully dissolved to obtain a second mixed solution.

[0056] In a four-neck flask equipped with stirring, thermometer, condenser, nitrogen, and dropping device, add the second mixed solution, heat slowly, raise the temperature to 70°C, react for 0.5 hours, slowly add the first mixed solution inward, drop Add time for 3 hours, keep warm for 5 hours. Cool down to below 40°C, add ethyl acetate until the solid content is 50%, and the reaction is complete.

Abstract

The invention provides a pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition comprises acrylate resin, a first solvent, tackifying resin and cellulose resin. An adhesive layer formed by curing the pressure-sensitive adhesive composition is good in adhesion, can be permanently attached to a base material and skin and is not prone to falling off from the skin or thebase material, solvent molecules and monomer residues in the middle and at the bottom of the adhesive layer are few, damage to the skin is not prone to being caused, the use effect of the pressure-sensitive adhesive is improved, and the application prospect is good.

Description

technical field [0001] The present invention relates to the field of materials. Specifically, the present invention relates to a medical pressure-sensitive adhesive composition, a preparation method thereof, and an adhesive material. Background technique [0002] Pressure-sensitive adhesive is an adhesive that can be bonded to the adherend only by applying external force. It is easy to use and has good stability. It has a wide range of applications in medical and health. Biomedical devices, transdermal drug release patches, medical labels and medical tapes, and many other applications. [0003] Among many types of medical pressure-sensitive adhesives, acrylic pressure-sensitive adhesives have two advantages: first, acrylic pressure-sensitive adhesives do not need to add other types of additives, and are single-component adhesives, which avoid potential damage caused by additives. Safety issues, and acrylic pressure-sensitive adhesives are polymerized in emulsion or solutio...
