Corrosion-resisting antibacterial medical rubber and preparation method thereof

Abstract

The invention discloses corrosion-resisting antibacterial medical rubber. The corrosion-resisting antibacterial medical rubber is prepared from the following raw materials in parts by weight: 40 to 55parts of brominated butyl rubber, 13 to 16 parts of flos lonicerae extract, 10 to 15 parts of an accelerant, 22 to 28 parts of maleic anhydride, 8 to 15 parts of hydroxylamine sulphate, 7 to 16 partsof cortex phellodendri extract, 6 to 10 parts of anti-aging agent mercaptobenzimidazole, 30 to 35 parts of ethylene-ethyl acrylate copolymer, 12 to 18 parts of a plasticizer, 2.5 to 3.8 parts of a flame retardant, 2 to 8 parts of an antibacterial agent, 5 to 6 parts of a diisocyanate compound solution, 4 to 5 parts of a hydrophilic substance solution, 10 to 13 parts of an inorganic silver-zinc compound antibacterial agent, 5 to 8 parts of a nano zirconium phosphate silver-loaded antibacterial agent and 5 to 7 parts of a saturated quaternary ammonium salt solution. The surface hydrophilicity and antibacterial property of the material can be obviously improved by soaking the rubber with the hydrophilic substance solution, polyethylene glycol and methacryloyloxyethyl phosphorylcholine; by adding the ethylene-ethyl acrylate copolymer, the medical rubber has better corrosion resistance and further the service life of the rubber is prolonged.

Description

technical field [0001] The invention relates to the technical field of corrosion-resistant and antibacterial medical rubber, in particular to a corrosion-resistant and antibacterial medical rubber and a preparation method thereof. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. Rubber not only provides people with daily and medical light industrial rubber products that are indispensable in daily life. [0003] Medical rubber is a good biological material, which is widely used in medical materials. Medical rubber products often have special requirements for it, such as corrosion resistance, non-toxicity, sterilization, physiological inertia, radiation resistance, etc. However, the existing medical rubber will produce toxic substances in the process, which will endanger human health, and its corrosion resistance and antibacterial properties are poor, resulting in a greatly reduced lifespan.
