Abstract

The invention discloses a preparation method for medical hydrocolloid dressing. The preparation method comprises the following steps:,1, dissolving styrene-butadiene-styrene block copolymer, then adding aliphatic series petroleum resins, carrying out the reaction, slowly adding cyclane oil, raising the temperature, then adding N.N-dibutyl dithio amido formic acid, and keeping the temperature to form a component A; 2, mixing anhydrosorbitol fatty acid ester and a polyoxyethylene sorbitan fatty ester condensation compound at normal temperature to form a liquid state component B; 3, taking sodium carboxymethyl cellulose, carboxymethyl chitosan, calcium alginate fibers and solid silver corpuscles, crushing the calcium alginate fibers into short fibers, mixing the substances at normal temperature to form a component C; and 4, adding the component B into the component A, raising the temperature, slowly stirring the mixture evenly and then adding the component C, stirring and cooling down the mixture, carrying out the debubbling in the vacuum, reducing the temperature, forming the dressing onto antiseize paper through injection moulding, and covering a PU film on the surface of the hydrocolloid to form a finished product.

Description

technical field [0001] The present invention relates to a kind of preparation method of medical hydrocolloid dressing Background technique [0002] Present dressing can only be treated for fixed wound, and is difficult to treat for the position that is difficult to fix, so will appear that many difficult wounds all can't be treated. Contents of the invention [0003] The invention provides a preparation method of a medical hydrocolloid dressing, which is not only beneficial to the healing of the wound, but also beneficial to the observation of the change of the wound. [0004] The present invention adopts the following technical scheme: a preparation method of medical hydrocolloid dressing, which comprises the following steps: Step 1, taking styrene-butadiene-styrene block copolymer and melting it in a reaction kettle, adding fat After reacting with petroleum resin for a period of time, slowly add naphthenic oil, increase the temperature, then add N.N-dibutyldithiocarbami...
