Abstract

The invention relates to a medical adhesive and a preparation method thereof, and belongs to field of adhesives. The medical adhesive comprises the following components in parts by weight: 10-18 parts of pectin, 10-25 parts of hydroxypropyl methyl cellulose, 2-8 parts of lignin, 6-10 parts of polyvinyl alcohol, 4-12 parts of an ethylene / vinyl acetate copolymer, 2-5 parts of methyl hydroxyethyl cellulose, 1-3 parts of castor oil, 2-4 parts of an acetic acid, and 10-18 parts of ethanol. The medical adhesive disclosed by the invention has good performances, and has a fast curing speed, so that the curing time is short; the medical adhesive disclosed by the invention is high in adhesive strength, and long in stabilizing time; and the preparation method disclosed by the invention is simple and practicable, and suitable for wide-range popularization and application.

Description

technical field [0001] The invention belongs to the technical field of glue, and in particular relates to a medical glue and a preparation method thereof. Background technique [0002] Glue is an intermediate that connects two materials. It mostly appears as a water agent. It belongs to the category of fine chemicals and has a wide variety. It is mainly classified by adhesive, physical form, hardening method and material of the adherend. The common ones are instant glue, epoxy resin bonding, anaerobic glue, UV glue (ultraviolet light curing), hot melt adhesive, pressure sensitive adhesive, latex and so on. If the glue is classified according to its composition, it mainly includes acrylate glue, composite structural glue, thermosetting polymer glue, water-based adhesive, solvent-based glue, natural adhesive, polymer adhesive, etc. [0003] At present, the existing medical glue is an emerging medical product that can replace sewing needles. The main component of medical glu...
