Abstract

The invention discloses a medical antibacterial silica gel material. The medical antibacterial silica gel material comprises, by weight, 80-100 parts of a sulfonyl aniline silica gel base material, 4-10 parts of a glass fiber, 10-15 parts of a polyester fiber, 10-15 parts of essential oil micropowder, 3-5 parts of nano-silver powder and 1-3 parts of a coupling agent. Antibacterial components are introduced through the essential oil micropowder and the nano-silver powder, and the sulfonyl aniline silica gel base material is used as a silica gel main body material, so that the long-acting antibacterial property of the silica gel material is effectively improved, and meanwhile, the medical antibacterial silica gel material has good thermal stability, antifouling property and mechanical property.

Description

technical field [0001] The invention relates to the field of medical polymer materials, in particular to a medical silica gel. Background technique [0002] In recent years, with the progress of society and the rapid development of science and technology, various new materials have sprung into people's lives one after another, bringing many conveniences to people's production and life, as well as visual aesthetics and aesthetics. comfortability. Among them, silicone material is one of these new materials. Because of its high thermal stability, excellent weather resistance, good electrical insulation, good physiological inertia, low surface tension and surface energy, it is widely used in aviation, cutting-edge technology, military, Construction, electrical and electronic, textile, automobile, machinery, leather and paper, chemical light industry, metal and paint, medicine and medical treatment and other fields. Silica gel materials in the prior art can be divided into two ...
