Abstract

The invention relates to a medical silicone rubber material modification technology, in particular to medical silicone rubber with a modified hydrophilic structure on the surface as well as preparation and application of the medical silicone rubber with the modified hydrophilic structure on the surface. The cleaning agent is prepared from 1, 5-di-tert-butyl peroxide hexane, activated carbon, a silver nitrate solution, chitosan and an acetic acid aqueous solution. The modified powder and the semi-finished product are mixed, so that the silicone rubber finished product is rich in silver ions, and the breeding of bacteria is effectively prevented; the medical silicone rubber prepared by the preparation method not only has a good antibacterial effect, but also has relatively high tear resistance, so that the problem that the silicone rubber in the prior art is generally relatively poor in tear resistance and does not have good antibacterial performance is effectively solved.

Description

technical field [0001] The invention relates to a modification technology of medical silicone rubber materials, in particular to a medical silicone rubber with a modified hydrophilic structure on the surface, as well as its preparation and application. Background technique [0002] Hydrophilic surface modification methods of silicone rubber include surface grafting method, plasma technology and surface coating method, among which the most commonly used method is surface grafting method. The principle of the surface grafting method is: After a certain chemical treatment, the surface of the silicone rubber has a polar group, and then the hydrophilic substance is grafted to the surface of the material by chemical reaction, thereby improving the surface hydrophilicity of the silicone rubber. Due to the special application field of medical silicone rubber, it is difficult to make silicone rubber have good thermal stability and antibacterial properties while ensuring hydrophilicit...
