The waterproof medical adhesive comprises the following components in parts by weight: 15-26 parts of silicone acrylic emulsion, 5-9 parts of natural rubber, 4-10 parts of potassium citrate, 10-16 parts of nano zinc oxide, 9-15 parts of nano silica, 5-11 parts of sodium carboxymethylcellulose, 2-5 parts of camphor seed kernel oil, 8-14 parts of polyvinyl alcohol, 10-18 parts of ethanol and 12-19 parts of water. The adhesive disclosed by the invention is good in adhesion and also good in waterproofness.

Description

technical field [0001] The invention belongs to the technical field of medical adhesives, and in particular relates to a waterproof medical adhesive and a preparation method thereof. Background technique [0002] Glue is an adhesive, that is, a substance that can bond two objects, and it must be applied between the two objects to play a bonding role. The chemical composition in the glue, in a water-based environment. Polymer body in the glue is generally rounded particle, and the radius of general particle is between 0.5~5 μm. The bonding between objects is achieved by the pulling force between the polymer bodies in the glue. In glue, water is exactly the carrier of polymer body, and water loads polymer body and is immersed slowly in the tissue of object. After the moisture in the glue disappeared, the polymer body in the glue just relied on mutual pulling force, with two objects combining tightly. During the use of glue, if the amount of glue is too much, the polymer ...
