Abstract

The invention discloses an anti-oxidation medical hot-melt pressure-sensitive adhesive and a preparation method thereof. The anti-oxidation medical hot-melt pressure-sensitive adhesive comprises the following components: tackifying resin, a thermoplastic elastomer, a softening agent, an antioxidant group and a tackifier group, wherein the tackifying resin is hydrogenated petroleum resin, the thermoplastic elastomer is SBS/SIS, the antioxidant group comprises a phenolic anti-aging agent, a peroxide decomposing agent and an ultraviolet absorbent, and the tackifier group comprises at least one selected from rosin modified resin, terpene resin, a maleic anhydride grafted compatilizer, microcrystalline wax, dicyclohexyl phthalate and polyisobutene. According to the invention, harm is not causedto skins during peeling while the adhesive force of the product is further improved, and all the components are nontoxic and harmless, have no irritation to the skins, and have low allergenicity. Inaddition, the oxidation resistance of the product is greatly improved, the application range of the product is expanded, and the bonding reliability is further ensured.

Description

technical field [0001] The invention relates to the field of medical hot-melt adhesives, more specifically, it relates to an anti-oxidation medical hot-melt pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Medical hot-melt adhesives are generally pressure-sensitive adhesives, such as common surgical gowns, band-aids, etc., all use medical hot-melt pressure-sensitive adhesives, which can be glued without using solvents or other means, which is convenient and practical. However, since medical hot-melt adhesives are generally used at low temperatures, the requirements for adhesiveness are relatively high. [0003] For example, the Chinese patent document with the authorized announcement number CN103740305B discloses a medical hot-melt adhesive, which includes butyl rubber, maleic anhydride graft compatibilizer, SEBS, EVA, hydrogenated petroleum resin, terpene resin, PE wax, naphthenic oil, polyisobutylene, rubber anti-aging agent, ant...
