Abstract
The invention provides a double-layer sandwich or multi-layer sandwich multi-latex condom and a preparation method thereof. The preparation method of the condom comprises the following steps: vulcanizing natural latex; emulsifying and dispersing polymer materials such as polyurethane or polyisoprene or butyronitrile or other non-natural latex and making the polymer materials into synthetic latex; and dipping a condom die in the natural latex and the synthetic latex respectively and then drying to finally obtain the double-layer sandwich or multi-layer sandwich multi-latex condom the middle layer of which is made from the natural latex or the synthetic latex, wherein, the innermost layer and the outermost layer of the condom can be made from the same material or different materials. The double-layer sandwich or multi-layer sandwich multi-latex condom of the invention has stretch rate and comfortability of the natural latex as well as high compactness of the synthetic latex, thus being applicable to obstructing penetration of small molecules such as hepatitis, AIDS virus and the like.
Description
Technical field
The present invention relates to condom, particularly double-deck sandwich or multilamellar sandwiched high-barrier condom and preparation method thereof.
Background technology
Condom is generally processed by Heveatex at present; This condom has better elastic; Relevant promoter aftershaping is good adding, and suitable men and women wears, but in the molecular structure of Heveatex a fixed gap is arranged; It is the above objects of 4000 nanoscales that these spaces can stop diameter, is the human body sperm etc. of 5000 nanometers like diameter; But for the littler diameter of molecule is the AIDS of 120 nanometers, the hepatitis virus of 40 nanometers etc., and Heveatex lacks the ability of blocking accordingly.Medical experiment proves that natural latex condom can't prevent the infiltration of HIV etc. safely.
Existing science and technology finds, polyurethane, gathers second and defends high molecular synthetic materials such as diene, butyronitrile, and its molecular structure and Heveatex have certain similarity, but compactness greatly improves, and its molecule space can separate the infiltration of AIDS, hepatitis virus etc. fully.
Summary of the invention
The purpose of this invention is to provide a kind of double-deck sandwich or multilamellar sandwiched high-barrier condom and preparation method thereof.The extensibility and the comfort of the existing Heveatex condom of this condom have the good compactness of macromolecular material of synthetic again.
The technical scheme that realizes the object of the invention is:
Utilize condom mold in the synthetic latex (above abbreviation synthetic latex) of Heveatex and synthetic, to flood, process double-deck sandwich or multilamellar sandwiched high-barrier condom.
The method for preparing of double-deck sandwiched high-barrier condom comprises the steps:
(1) Heveatex carry out sulfurization;
(2) with polyurethane or gather macromolecular material that second defends non-natural latex such as diene or butyronitrile and carry out emulsifying and disperse, form emulsion, add compounding ingredients such as Heveatex, promoter, age resistor, zinc oxide, fully stir, form synthetic latex;
(3) Heveatex is injected the first road glue groove and the 3rd road glue groove, synthetic latex is injected the second road groove;
(4) with condom mold behind the first road glue drill traverse glue, form glued membrane, drying, get into the second road glue drill traverse glue after, after drying, get into the 3rd road glue drill traverse glue after, after drying forms the condom of a double-deck sandwich;
(5) water flushing mould dashes condom and to take off from mould, uses the drying machine after drying to be Heveatex, the interlayer double-deck sandwich high-barrier condom as synthetic latex inside and outside processing.
The order of adjustment dipping, can process inside and outside is that synthetic latex, interlayer are the condom of Heveatex; Or increase dipping number of times; Can process multilamellar sandwiched high-barrier condom, inject synthetic latex such as the first road glue groove, the second road glue groove injects Heveatex; The 3rd road glue groove injects synthetic latex; The 4th road glue groove injects natural emulsion, floods in order and opens dry molding, forms multilamellar sandwiched high-barrier condom.Can also use different synthetic latexes and Heveatex to mix utilization by different order, as: inject in the first road glue groove and gather second and defend diene, the second road glue groove injects Heveatex, and the 3rd road glue groove injects polyurethane and processes condom.
Described Heveatex is a prior art.
Described synthetic latex is meant, polyurethane or gather the macromolecular material that second is defended non-natural latex such as diene or butyronitrile adds the relevant raw material that cooperates, fully emulsified dispersion after stirring, the formation emulsion, synthetic latex.Its materials and materials weight part ratio are:
