Problems solved by technology

The "New England Journal of Medicine" reported that the failure rate of condoms to prevent AIDS was 16.7%, and the "British Social Science Medical Journal" reported that the failure rate of condoms to prevent AIDS was as high as 31%; the National Institutes of Health (NIH), Food and Drug Administration FDA, Centers for Disease Control and Prevention (CDC) and the United States Agency for International Development (US-AID) jointly formed a scientific task force to examine hepatitis B, AIDS, gonorrhea, chlamydia, syphilis, chancroid, lymphogranuloma venereum, Several sexually transmitted diseases, including genital herpes and genital warts, found that currently widely used condoms do not prevent the transmission of any of the sexually transmitted diseases

preparation example Construction

[0032] The high -resistance condom of the present invention uses graphene modified natural latex to be prepared on the condom mold, and the preparation method of graphene modified natural latex includes the following steps:

[0033] 1) Mix the graphene powder with the decentralized auxiliary agent in proportion.The concentration of graphene in nano-decentralization A is 0.5-50mg / ml, the size of the graphene after grinding is 200-800nm, and the thickness is 1-3nm., Pleurotic plus O, Sodium Polar Phosphate, Diffengers NF, Sixteenanel Penzenzine Sulfate, Siliconhane Benzene Sulfate, Stabilizer LW, Sodium Global Sulfate, and TexotylhumidaAt least one mixture of sulfonate.

[0034] 2) After adding a stabilizer and surfactant to the natural latex solution under the continuous stirring state, continue to stir for 5-10 minutes; then slowly add the granular nano-dispersed solution A, and continue to stir for 5-10 minutes; add promoter, then add promoter, then add promoter,Anti -agent, vulc...

Embodiment 1

[0048] The high -resistance condoms of this embodiment are prepared by graphene modified natural latex, and the preparation method of graphene modified natural latex includes the following steps:

[0049] 1) Mix the dispersing additives with the graphene powder at 10: 1 according to the quality ratio, and the graphene nano -decentralized liquid A is obtained after grinding;The graphene size after grinding is 500-700nm and the thickness is 1-3nm. The grinding equipment is grinded for 6 hours during grinding;liquid.

Abstract

The invention discloses a graphene modified natural emulsion preparation method and a high barrier condom. The graphene modified natural emulsion preparation method and the high barrier condom have the beneficial effects that firstly graphene and a dispersing agent mixed liquor are mixed, ground and stirred and then the product is mixed in a natural emulsion aqueous solution, so that graphene can be uniformly dispersed in emulsion and the strength of a natural emulsion composite material is improved; meanwhile, the number of micropores is smaller due to the graphene / emulsion composite action, thus greatly reducing the virus penetration probability; the thickness of the graphene condom can be 5-80mu m, so that the use requirements of the condom can be met; dense high barrier packing layers are formed by the composite crosslinked nano-packing technology, so that the natural gaps among molecules are reduced; therefore not only can HIVs be blocked but also hepatitis B viruses, hepatitis C viruses, human papilloma viruses, and the like, and most harmful bacteria, which are smaller than the HIVs, can not pass through the micropores.

Description

Technical field [0001] The present invention is a composition technology field of natural rubber. It is specifically for a graphene modified natural latex preparation method and high -resistance condom. Background technique [0002] The role of condoms is mainly used to prevent pregnancy and prevent sex diseases, also called condoms.However, some research projects and a large amount of international data from the National Family Planning Commission of China show that the materials used in the current market are mainly natural latex, and their natural cracks are about 3000Nm, which is enough to prevent human sperm head with a diameter of about 5000nm.However, the diameter of AIDS virus is only 120nm, the diameter of human papilloma virus is between 45-55nm, and the diameter of large spherical particles in hepatitis B virus is 42nm.The volume of various viruses is far less than the natural cracks of natural latex. Even if the condom is used correctly, it is still possible to infect...
