Problems solved by technology

The existing medical adhesives, due to the imperfect formula and generally use SO2 as a polymerization inhibitor, are difficult to control the dosage, making the molded product unstable, the curing speed is not ideal during use, and the adhesive strength is not enough. Moreover, during use Prone to albinism, highly irritating to the human body, causing a burning sensation

Abstract

The invention provides a medical adhesive made from a medical polymer material and a preparation method of the medical adhesive. The adhesive consists of polyacrylate, tragacanth, polymethacrylate, squalane, benzoyl peroxide, glycerin rosin resin, dimethyl sebacate, hydroquinone, p-benzenemethanesulfonic acid, dioctyl phthalate, tertiary calcium phosphate and sodium alginate. The preparation method comprises the following steps: firstly, mixing the polyacrylate, the tragacanth, the polymethacrylate and the squalane, then adding the benzoyl peroxide and the glycerin rosin resin, and stirring so as to obtain a mixture I; then, mixing the dimethyl sebacate, the hydroquinone, the p-benzenemethanesulfonic acid, the dioctyl phthalate, the tertiary calcium phosphate and the sodium alginate so as to obtain a mixture II; and mixing the mixture I and the mixture II, heating, preserving heat, and cooling to room temperature, so that the medical adhesive is obtained. The medical adhesive disclosed by the invention is moderate in curing speed, long in duration of keeping stable and high in bonding strength.

Description

technical field [0001] The invention belongs to the technical field of medical polymer materials, and in particular relates to a medical adhesive and a preparation method thereof. Background technique [0002] The use of medical adhesives dates back centuries. The beginning is to obtain animal glue from animal skin, tendon, and cartilage. The ancient Romans in Egypt around 3000 BC first used a mixture known as a medical adhesive, and later the ancient Greeks prepared a medical plaster-like mixture from olive oil, lead oxide and water. In 1845, one of the first patents was granted for a natural rubber pressure-sensitive adhesive used as a surgical adhesive tape. In 1936, the German Kulzeer Co company sold dental adhesives based on methyl methacrylate (MMA). In 1959, the United States Eastman910 fast adhesive (α-methyl cyanoacrylate) came out, realizing the great revolution of surgical operation from sewing, sticking to bonding. In 1960, Charnly was the first to successful...
