Abstract
The present invention relates to a nano compound condom, Every condom contains a solid metal cation carrier material which is formed from (NaAg)2ZrPO4 or (NaNn)2ZrPO4 or (NaCu)2ZrPO4 or their mutually-combined product and whose microparticle size is below 0.1 micrometer and whose weight is 0.01-0.8 of that of emulsion. Its released metal cation can change the chemical composition of bacterial mechanism, and can break the acid protein on which the bacteria depend for existance, can kill AIDS vines and various VD pathogens, and can prevent cross-infection.
Description
The present invention relates to the contraceptive that a kind of male uses.
Condom is made by natural rubber.Will drip silicone oil during production as lubricant behind the condom demoulding, the adding therein that also has appoints menthylphenoxypolyethoxy ethanol as spermicide.These additives are with on gel state or the liquid surface attached to condom.This condom does not have sterilizing function, inoperative to HIV (human immunodeficiency virus), all kinds of sexually transmitted disease (STD) pathogenic bacteria, can only divide contagion by blocking part, but can't block to reach in use and use the back secondary infection, in use break or come off or rotten carrying disease germs when not using as condom, use the back to withdraw from condom adversary's infection, perhaps throw aside improper infection to other people etc. with hands.
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of and can kill HIV (human immunodeficiency virus), nano composite condom of all kinds of sexually transmitted disease (STD) pathogenic bacterias and manufacture method thereof.
Nano composite condom of the present invention contains 0.01%～8% (NaAg) of particle size below 0.1 μ m of latex weight in every condom
2ZrPO
4Or (NaZn)
2ZrPO
4Or (NaCu)
2ZrPO
4Or wherein the solid that mutually combines of the two or three carries the metal cation material.
Nano composite condom of the present invention, wherein containing solid in every condom, to carry the metal cation material be 1% of latex weight.
Nano composite condom of the present invention, wherein containing solid in every condom, to carry the metal cation material be 2% of latex weight.
The manufacture method of nano composite condom of the present invention comprises following process steps:
1, with grinder solid is carried metal cation material (NaAg)
2ZrPO
4Or (NaZn)
2ZrPO
4Or (NaCu)
2ZrPO
4Grind to form the powder of particle size below 0.1 μ m;
2, with 0.01%～8% the ratio of making the used latex of condom above-mentioned solid is carried a kind of in the metal cation powder or two kinds or three kinds and add in the latex, and stir;
3, produce dipping, the oven dry sulfuration, the demoulding dries, and the sulfuration of back step detects.
Nano composite condom of the present invention carries metal cation anti-biotic material (NaAg) because of wherein containing
2ZrPO
4Or (NaZn)
2ZrPO
4Or (NaCu)
2ZrPO
4These years, the metal cation anti-biotic material was to be evenly distributed on the latex surface with " island " shape in latex, the release of its metal cation is extremely faint, and sterilization is to carry metal cation anti-biotic material contact microorganism face by latex surface " island " shape to realize.Therefore, each face of condom and position all are sterilization bodies, when all touch-safes overlap, have the metal cation (silver ion, zinc ion, copper ion) of biocidal efficacies to discharge, and produce efficient germicide.The body fluid that human body is secreted, during as perspiration, seminal fluid and genitals secretions touch-safe cover, metal cation promptly discharges from the condom surface, be free in the body fluid with positively charged metallic atom nuclear, in case the antibacterial of contact zones negative charge immediately bacterial body is held, when ion concentration reach certain after, in the antibacterial body, permeate rapidly, change the chemical composition of antibacterial body, destroy the acid albumin that antibacterial depends on for existence, thereby make its destruction.Therefore, in condom uses, cross infection can not occur, come off, in human body fluid, be full of metal cation, can play to intercept yet and infect purpose even condom breaks.Because of whole condom is a sterilization body, particularly other positions of health touch after use, all will be aseptic contacts.The metal remained cation also can continue sterilization, has avoided condom to throw aside and then the third party has been infected.
Other details of nano composite condom of the present invention and manufacture method thereof and characteristics can be cheer and bright by reading the embodiment hereinafter encyclopaedize.
The difference of the method that nano composite condom of the present invention overlaps with known production safety on making is and will adds (NaAg) of particle size below 0.1 μ m in the latex of the production safety cover for preparing
2ZrPO
4Or (NaZn)
2ZrPO

4The powder that carries the metal cation anti-biotic material, its ratio should be latex weight O.01%～8%.The model that these years, the metal cation anti-biotic material can be produced with U.S. UP company is that UP400 type grinder grinds to form the powder below the 0.1 μ m.In latex, can add wherein a kind ofly, also wherein two kinds or three kinds can be added together, also chemical reaction can not take place each other.After add carrying the metal cation anti-biotic material, need to stir make in 30 minutes and carry the even branch of metal cation material in latex, technology is routinely then manufactured by international standard ISO4074-1 and to be carried a metal cation condom.
Embodiment 1.
To be that metal copper ion pressed powder, metallic zinc ion solid powder or the argent ion solid powder of carrier is that 0.01: 100 ratio is sneaked into and made respectively 100 of condoms in the latex in carrying metal cation pressed powder and latex weight ratio with the phosphoric acid zirconates, its production code member is respectively 01,02, No. 03, detect under 20 ℃ by standard GB7544-92, its sterilizing rate and physical property testing result are as shown in table 1.
Embodiment 2.
To be that metal copper ion pressed powder, metallic zinc ion solid powder or the argent ion solid powder of carrier is that 1: 100 ratio is sneaked into and made respectively 100 of condoms in the latex respectively in carrying metal cation pressed powder and latex weight ratio with the phosphoric acid zirconates.Its production code member is respectively 01,02, No. 03, detects under 20 ℃ by standard GB7544-92, and its sterilizing rate and physical property testing result are as shown in table 2.
Embodiment 3.
To be that metal copper ion pressed powder, metallic zinc ion solid powder or the argent ion solid powder of carrier is that 2: 100 ratio is sneaked into and made respectively 100 of condoms in the latex respectively in carrying metal cation pressed powder and latex weight ratio with the phosphoric acid zirconates.Its production code member is respectively 01,02, No. 03, detects under 20 ℃ by standard GB7544-92, and its sterilizing rate and physical property testing result are as shown in table 3.
Embodiment 4.
