Problems solved by technology

The volume of sperm in semen is much larger than the space gap of rubber molecules to achieve the contraceptive effect. However, some viruses such as syphilis and AIDS have smaller molecular volumes than natural rubber latex. The molecular space structure cannot be sealed and is easy to get sick.

Abstract

The present invention discloses applications of nanometer active carbon in preparation of family planning products, wherein the family planning products are condoms, the raw materials of the condoms mainly comprise nanometer active carbon and a natural latex liquid, the mass percentage of the nanometer active carbon is 1-3%, the particle size of the nanometer active carbon is 1-100 nm, and a hydroxyl functional group is modified on the surface of the nanometer active carbon. According to the present invention, the nanometer active carbon has the high antibacterial and antivirus effect, has the particle size of 1-500 nm, and can fill the 5000-70000 nm gap in the latex film of the condom, such that the good antibacterial and antivirus function can be provided and the spread of various diseases can be prevented after the nanometer active carbon is added to the latex to prepare the condom; and the lubrication performance of the condom after the nanometer active carbon adding is substantially improved, the flexibility is good, the problems of aging, breaking and the like are not easily generated, the contraception effect is good, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of nano activated carbon application, in particular to the application of nano activated carbon in preparing family planning products. Background technique [0002] According to the latest report of the World Health Organization, 2.5 million people were newly infected with HIV in 2011, and an estimated 1.7 million people died, which is 700,000 fewer than the number of new infections worldwide ten years ago, and 700,000 fewer than the number of deaths in 2005. 600000. The "Joint Assessment Report on AIDS Prevention and Control in China" pointed out that by the end of October 2007, my country had reported a total of 223,501 HIV-infected and AIDS patients, including 62,838 AIDS patients and 22,205 deaths. Condoms prevent pregnancy as a non-drug form. In addition, condoms also have the effect of preventing sexually transmitted diseases such as gonorrhea and AIDS (HIV), so they are also called condoms. Today's ...
