Problems solved by technology

[0007] If in-situ polymerization and compounding with latex are used, in the strong alkaline natural rubber emulsion, although the graphene oxide derivatives will be better dispersed, they cannot achieve a transparent and colorless state
Non-oxidized transparent graphene, such as direct in-situ compounding, because it lacks the interaction between functional groups and rubber molecules, will shrink and curl directly during stirring or ultrasonication, and cannot be fully stretched and spread, which will affect the insulation and insulation effect of the composite latex

Embodiment 1

[0036] In the present embodiment, the preparation method of the transparent colorless composite latex condom with high insulation and high strength is as follows:

[0037] A total of 10 groups of CVD-grown graphene copper foil plates (100×100 cm) were connected to electrode clips as cathodes. 10 groups of graphite flakes (100×100cm) are used as anodes, corresponding to the cathodes one by one, and placed in relative combination. Then spray polyvinylpyrrolidone (average molecular weight: 450,000) hydrogel solution with a mass concentration of 25% on the copper foil panel, with a thickness of about 0.1 mm. Put all the panels into the glass tank of the sonicator to hold the water, connect the power supply, and turn on the sonicator. The electrolysis voltage is 20V, and the water temperature is controlled at about 80°C. Ultrasonic power density is 1W / cm 2, the ultrasonic frequency is 40kHz. Ultrasound shatters and falls off the graphene, and at the same time electrolyzes the w...

Embodiment 2

[0039] In the present embodiment, the preparation method of the transparent colorless composite latex condom with high insulation and high strength is as follows:

[0040] A total of 10 groups of CVD-grown graphene nickel plates (100×100 cm) were connected to electrode clips as cathodes. 10 groups of graphite flakes (100×100cm) are used as anodes, corresponding to the cathodes one by one, and placed in relative combination. Then, the polyvinylpyrrolidone (average molecular weight: 850,000) hydrogel solution with a mass concentration of 30% was sprayed on the nickel foil panel with a thickness of about 0.08mm. Put all the panels into the glass tank of the sonicator to hold the water, connect the power supply, and turn on the sonicator. The electrolysis voltage is 15V, and the water temperature is controlled at about 70°C. Ultrasonic power density is 0.8W / cm 2 , the ultrasonic frequency is 40kHz. Ultrasound shatters and falls off the graphene, and at the same time electrolyz...

Embodiment 3

[0042] In the present embodiment, the preparation method of the transparent colorless composite latex condom with high insulation and high strength is as follows:

[0043] A total of 10 groups of CVD-grown graphene quartz plates (100×100 cm) were connected to electrode clips as cathodes. In addition, a total of 10 groups of CVD-grown graphene quartz plates (100×100 cm) were connected with electrode clips as anodes, corresponding to the cathodes one by one, and placed in relative combinations. Then spray the polyvinylpyrrolidone (average molecular weight: 1,100,000) hydrogel solution with a mass concentration of 35% on the nickel foil panel, with a thickness of about 0.06mm. Put all the panels into the glass tank of the sonicator to hold the water, connect the power supply, and turn on the sonicator. The electrolysis voltage is 10V, and the water temperature is controlled at about 60°C. Ultrasonic power density is 0.8W / cm 2 , the ultrasonic frequency is 40kHz. Ultrasound sh...

Abstract

The invention relates to the fields of composites and medical instruments and specifically relates to a preparation method of a transparent and colorless composite latex condom with high insulating property and high strength. The preparation method comprises the steps: connecting a panel covering transparent graphene with an electrode holder, spraying a polyvinylpyrrolidone glue solution on the panel, and then, placing the panel into an insulated vessel holding water; electrifying for electrolysis, meanwhile, shattering and stripping graphene adsorbed by polyvinylpyrrolidone under the assistance of ultrasound, and finally, uniformly dispersing graphene into water; and concentrating the solution to form composite gel, then, circulating the former processes, finally, stirring and dispersingthe composite gel into vulcanized natural latex to obtain a composite latex emulsion, and then, preparing a pure transparent graphene composite condom. The graphene composite condom prepared by usingthe preparation method is pure in color, transparent and good in color adjustability and has the advantages of high insulating property and high strength.

Description

technical field [0001] The invention relates to the field of composite materials and medical devices, in particular to a method for preparing a high-insulation, high-strength transparent colorless composite latex condom. Background technique [0002] Condoms, also known as condoms, are a simple and effective physical isolation contraceptive tool that is widely used. The research report shows that the condom film can effectively shield the pathogens of sexually transmitted diseases, AIDS and other diseases, and the correct use can significantly reduce the infection rate of sexually transmitted diseases. At present, most condoms are made of natural latex. Because natural latex has good film-forming properties, high bio-affinity, good mechanical properties, and is pure white and transparent. However, due to the structural characteristics of latex itself, there are naturally micropores with diameters ranging from several hundred to several thousand nanometers on the membrane, w...
