Abstract:
The invention relates to a novel cyanoacrylate medical adhesive and preparation method and application thereof, the main components of the medical adhesive is composed of alkyl cyanoacrylate and/or alkoxv cyanoacrylate and lactyl cyanoacrylate, and by adding a novel stabilizer system, the stability of the novel cyanoacrylate medical adhesive product in the invention increases substantially, the product can be stored and transported at room temperature, degradation performance of the product was greatly improved, the main technical indicators of product such as curing time and mechanical properties can meet the clinical needs, and the user experience of the product such as adhesive film flexibility is greatly improved, so the cyanoacry late medical adhesive is an widely used surgical hemostatic materials.

Claim (Index 9):
A method for preparing the cyanoacrylate medical adhesive of  claim 1 , comprising the following steps:\n 1) weighting successively alkyl cyanoacrylate and/or alkoxy cyanoacrylate, lactyl cyanoacrylate, free radical polymerization inhibitor, anion polymerization inhibitor and natural antioxidant, mixing evenly to obtain colorless liquid; 2) adding gas polymerization inhibitor to the colorless liquid obtained in step 1), then sealing well, and stirring for 12-24 hours at room temperature; and 3) under the condition of local hundred class, filtering the mixture obtained in step 2 to remove bacteria and obtain sterile degradable cyanoacrylate medical adhesive.
