Embodiment 1

[0029] The reagents used were commercial reagents unless otherwise specified, and were not further purified before use.

[0030] The preparation method of modified nano tourmaline powder / oregano oil extract-latex antibacterial film specifically comprises the following steps:

[0031] (1) Add 60g of nano-tourmaline powder (average size is 40nm-60nm) into 140ml of water and stir to prepare a slurry with a mass fraction of 30%, stir at 60°C for 30min, and add 2% of the mass fraction of tourmaline powder. Stearic acid (i.e. 1.2g), the obtained mixture is continuously stirred for 25min for modification, and the obtained solid is dried to obtain modified nano tourmaline powder after filtration;

[0032] (2) Put the oregano oil in a drying box and dry it at 90° C. for 4 hours, then take it out and cool it to room temperature, and grind the dry oregano oil into fine powder. Weigh 50g of oregano oil powder, wrap it with filter paper and then hang it in the middle and lower part of the...

Abstract

The invention discloses a preparation method of a modified nano-tourmaline powder/origanum oil extracting solution-rubber latex antibacterial film. The preparation method includes the steps: preparingmodified tourmaline powder and origanum oil extracting solution; performing reaction on natural rubber latex, the origanum oil extracting solution, vulcanizing ingredients and the modified tourmalinepowder to prepare modified nano-tourmaline powder/origanum oil extracting solution-natural rubber latex composite emulsion; finally, pouring the composite emulsion into a framed glass plate, drying the composite emulsion to form a film, placing the obtained dry film into a vacuum drying box, and performing additional vulcanization experiments to prepare the antibacterial film. The origanum oil extracting solution in the prepared antibacterial film contains 30 or more antibacterial compounds and can strongly kill most pathogenic bacteria, the antibacterial performance of the prepared compositerubber latex can be effectively improved when the origanum oil extracting solution is added into the natural rubber latex, and the added natural tourmaline powder can continuously release negative ions and far infrared rays for providing energy for a human body, can promote metabolism of the human body and has the healthcare functions of removing toxicity, balancing the pH (potential of hydrogen)value of the human body and the like.

Description

technical field [0001] The invention relates to a preparation method of a natural latex antibacterial composite film, in particular to a preparation method of a modified nanometer tourmaline powder / oregano oil extract-latex antibacterial film. Background technique [0002] Natural latex is produced from Hevea, its products have excellent comprehensive properties and irreplaceability, and are widely used in the preparation of impregnated products, molded products and sponge latex products, such as medical catheters, medical gloves and condoms and other medical products . With the improvement of people's living standards, the requirements for latex products not only need to meet high mechanical strength, heat resistance and aging resistance, but also have antibacterial properties. At present, there are few domestic and foreign literature reports on natural latex composite materials with antibacterial properties, and there is no obvious breakthrough in the research on antibact...
