Problems solved by technology

[0002] At present, natural latex rubber condoms are non-sterile products, and the product is easily contaminated during production and use, producing bacteria, which is easy to cause infection, and even the secondary metabolites of bacteria may easily cause skin allergies or lesions
At present, the main standard for condoms is GB15979-1995 "Hygienic Standards for Disposable Hygienic Products". As an antibacterial product, if you want to achieve antibacterial products, in addition to the products meeting the above standards, the antibacterial rate against Escherichia coli and Staphylococcus aureus is ≥50% (dissolution), and the current international production of products cannot achieve antibacterial effects.

Embodiment 1

[0035] Raw material preparation: 100 parts of natural rubber latex, 0.7 parts of zinc oxide, 1.2 parts of sulfur, 0.3 parts of accelerator PX, 0.4 parts of accelerator ZDC, 0.9 parts of antioxidant WSL, 0.5 parts of physical antibacterial agent

[0036] (1) Preparation of emulsion:

[0037] ① Dilute 60% natural rubber latex to 55% with deionized water.

[0038] ② Add zinc oxide, sulfur, accelerator, and antioxidant according to a certain formula ratio when the above-mentioned latex is stirred (normal temperature), and continue to stir for 60 minutes.

[0039] ③ Add physical antibacterial agent to the latex of ② and continue stirring for 60 minutes.

[0040] ④The total solid content of the above rubber materials is controlled at 55±2%, and the chloroform value of the vulcanized rubber is controlled at the third middle to the third end. The quality indicators are sent to the laboratory for testing.

[0041] ⑤ Use deionized water to adjust the total solid content to 48±2% afte...

Embodiment 2

[0068] Raw material preparation: 100 parts of natural rubber latex, 1.1 parts of zinc oxide, 0.8 parts of sulfur, 0.6 parts of accelerator PX, 0.1 part of accelerator ZDC, 1.2 parts of antioxidant WSL, 0.25 parts of physical antibacterial agent

[0069] Its preparation method is with embodiment one.

Embodiment 3

[0071] Raw material preparation: 100 parts of natural latex, 1.0 part of zinc oxide, 1.0 part of sulfur, 0.4 part of accelerator PX, 0.2 part of accelerator ZDC, 1.0 part of antioxidant WSL, 0.4 part of physical antibacterial agent

[0072] Its preparation method is with embodiment one.

[0073] The above formula and the prepared condom have the following advantages: they can physically kill bacteria in seconds; the physical antibacterial agent is a kind of ore fiber that has a reinforcing effect, and the physical properties of the product are improved by more than 10%; Allergic skin reactions have an adjuvant therapeutic effect.

Abstract

The invention relates to an antibacterial rubber condom and a preparation method thereof. The antibacterial rubber condom is prepared by using natural latex as a base material, and is prepared from the following raw materials in parts by mass: 100 parts of the natural latex (weighed based on dry latex), 0.7-1.1 parts of zinc oxide with 50% dispersion, 0.8-1.2 parts of sulfur with 50% dispersion, 0.3-0.6 part of an accelerant PX with 50% dispersion, 0.1-0.4 part of an accelerant ZDC with 50% dispersion, 0.9-1.2 parts of an antioxidant WSL with 50% dispersion, and 0.25-0.5 parts of a physical antibacterial agent with 10% dispersion. The antibacterial rubber condom is prepared by the steps of preparing emulsion, dipping, drying and vulcanizing, carrying out electric inspection, and the like.The antibacterial rubber condom has very good antibacterial effect and sterilizing effect.
