example 1

[0023]Put nitrile rubber, fluorosilicone rubber and sulfur into a mixer at a mass ratio of 3:2:1, and mix for 1 hour at a temperature of 120°C to obtain a self-made vulcanized mixed rubber; weigh 28g of a particle size of 55nm Pour the superfine alumina powder into a beaker with 4mL polyethylene glycol and 65mL deionized water and mix and stir for 8min to obtain a self-made superfine alumina aqueous dispersion. The aluminum water dispersion, deionized water and absolute ethanol were mixed and placed in a four-necked flask equipped with a condenser, a thermometer and a stirrer, stirred for 16 min, heated to 65 ° C, and then added to the four-necked flask with 10 mL of 35 % silver nitrate solution and 1mL silane coupling agent KH-570, continue to heat and stir for 24min, filter and remove the filtrate to obtain a filter residue, wash the filter residue twice with deionized water, and finally put it in an oven and dry it at a temperature of 55°C 35min, cooling and discharging to ...

Abstract

The invention discloses a preparation method of antibacterial and wear-proof medical rubber gloves and belongs to the technical field of rubber preparation. The method comprises steps as follows: firstly, nitrile rubber, fluorinated silicone rubber and sulfur are mixed at a certain temperature, homemade sulfurized mixed glue is formed, the dispersity of superfine particles in a matrix is advantageously improved, and improvement of uniform dispersity and hardness of wear-proof substances in the rubber gloves is promoted, and the wear resistance of the rubber gloves is advantageously improved; then, the insides of the rubber gloves are effectively filled with quartz sand powder. Superfine aluminum oxide powder is soaked in a silver nitrate solution, a silver-supporting structure layer is formed, bacteria are accordingly killed, and the antibacterial property of the rubber gloves is improved. A homemade antibacterial emulsion is prepared from nano zinc oxide and isothiazolinone through mixing, rubber glove bodies are soaked in the homemade antibacterial emulsion, and bacteria are killed; besides, metal ions are released slowly when nano zinc oxide and bacteria make contact, the wear resistance of the rubber gloves is further improved and the antibacterial and wear-proof medical rubber gloves have broad application prospects.

Description

technical field [0001] The invention discloses a preparation method of antibacterial and wear-resistant medical rubber gloves, belonging to the technical field of rubber preparation. Background technique [0002] Rubber gloves are a type of gloves made of rubber sheets or films. According to rubber raw materials or manufacturing process, latex gloves and molded gloves are classified. Acid and alkali resistant gloves should be able to be used in sulfuric acid (density 1.32) or caustic soda solution (density 1.19) at 45°C. Electrically insulating gloves are divided into high-voltage and low-voltage. High voltage can be used below 6000 volts (the test voltage is 12000 volts). Low voltage can be used below 1000 volts. There are two types of medical gloves: smooth surface and wool surface (hair surface gloves or wrinkle gloves). [0003] Gloves have been widely used in people's production and life because of their barrier protection and can well protect the safety of users. ...
