Abstract

The invention relates to a hot-melt and pressure sensitive plaster matrigel. The hot-melt and pressure sensitive plaster matrigel is prepared by the following raw materials by weight: 5-25 parts of a thermoplastic elastomer SIS, 5-25 parts of a thermoplastic elastomer SBS, 5-20 parts of a thermoplastic elastomer SEPS, 5-30 parts of a C5 petroleum resin, 5-30 parts of a C5/C9 co-polymerized petroleum resin, 10-30 parts of a rosin resin, 10-30 parts of a naphthenic oil KNH4010 and 1-2 parts of an antioxidant BHT264. The hot-melt and pressure sensitive plaster matrigel is prepared a method of passing through nitrogen and then fusing with stirring. The plaster matrigel prepared by the method has the advantages of good initial adhesion, large release force, good ageing-resistant performance and high cohesive strength. Compared with a nonpolar material, the plaster matrigel has relatively good combined performance and is helpful for coating. When the plaster matrigel is in use, skins are not allergic to the plaster matrigel, and drug loading capacity is large; and no residue is left after the matrigel is peeled off.

Description

technical field [0001] The invention relates to a hot-melt pressure-sensitive adhesive, in particular to a hot-melt pressure-sensitive plaster base glue. Background technique [0002] Pressure-sensitive adhesive is a self-adhesive substance that is sensitive to pressure during the bonding process. It can form a relatively firm bond with a small force. Hot melt pressure sensitive adhesive is one of them, which can produce excellent hot tack at slightly above room temperature, is solid at room temperature, and can produce strong adhesion with fingers or light pressure. Compared with ordinary hot-melt pressure-sensitive adhesives, hot-melt pressure-sensitive plaster base adhesives need to be in contact with the skin, so they must have hypoallergenic properties, good moisture permeability, moderate peel strength, and good cohesion to prevent the adhesive from remaining on the skin. High requirements for drug loading are required. [0003] At present, the main component of the ...
