Abstract

The invention discloses photo-curing adhesive for oral cavities and a method for preparing the photo-curing adhesive. The photo-curing adhesive for the oral cavities comprises, by weight, 67-78 parts of epoxy resin, 12-19 parts of polyisobutene, 4-15 parts of tributyl citrate, 2-13 parts of p-toluenesulfonic acid, 16-37 parts of glycerin, 1-7 parts of chitin, 4-17 parts of tridodecylamine, 3-12 parts of hydroxyethyl methacrylate, 2-9 parts of tartaric acid and 3-10 parts of N, N-dimethyl-p-toluidine. The photo-curing adhesive for the oral cavities and the method have the advantages that synergistic effects are realized by various components of the photo-curing adhesive, accordingly, the adhesion strength can be guaranteed, the photo-curing time can be effectively shortened, allergy phenomena can be prevented, and the photo-curing adhesive and the method have excellent market prospects.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a light-cured oral adhesive and a preparation method thereof. Background technique [0002] The use of medical adhesives has a long history and plays a very important role in clinical practice, and has developed rapidly in recent decades. [0003] An ideal medical adhesive should have the following properties (1) safe, reliable, non-toxic, and non-toxic (carcinogenic, teratogenic, mutagenic); Healing; (3) sterile and can be kept sterile for a certain period of time; (4) fast bonding can be achieved under normal temperature and pressure; (5) good bonding strength and durability, and the bonding part has a certain (6) It is non-irritating to human tissue during use; (7) It can be gradually degraded, absorbed and metabolized after reaching the effect of use; (8) It has a good use state and is easy to store. [0004] In the course of clinical use, especially in the fiel...
