Description
Technical field
The present invention relates to sex aids field, more particularly to a kind of manufacture method of fine and close inner membrance graphene sheath.
Background technology
Current most common sheath is generally natural emulsion sheath, but this contraception is cased with three defects：One be by
It can not be removed in a part of water soluble protein contained admittedly, fraction crowd be easily caused allergic, there is potential safety hazard；Two are
Limited by its method of manufacturing technology, thickness is thicker, easily reduce usage experience；Three are limited by natural emulsion material self character,
Poor thermal conductivity, same easily reduction usage experience.
With the development of science and technology, some producers gradually start to release the sheath of polyurethane material, this material
There are five big advantages for natural emulsion：Intensity height, compactness height, good biocompatibility, thickness of thin, heat conduction are fast.But
Also there is the place of some relative deficiencies simultaneously：One is poor toughness, and it is high that damaged and extrusion rate compares natural emulsion sheath；Two be phase
To more brittle, serious forgiveness is low when using；Three be that draw ratio is low, can not be generally applicable to the crowd with different physiological characteristics.
For these problems of the prior art, in a kind of in the market densification that urgently elasticity is high, intensity is high, skin softening is good
Film graphene sheath.
The content of the invention
To solve drawbacks described above present in prior art, the present invention is intended to provide intensity is high, consistency is high, wear-resisting, anti-corrosion, anti-
Impact, the manufacture method of the fine and close inner membrance graphene sheath of service life length.
In order to realize foregoing invention purpose, the present invention uses following technical scheme：The fine and close inner membrance graphene of one kind manufacture is kept away
The method of pregnant set, comprises the following steps：
1）It is prepared by internal layer
1. prepare to be built-in with the silica column round end mould of coiled carbon fibers thermal source in confined space；
2. in the pure copper layer of 5 μm -8 μm of silica column inner mould surface coating thickness；
3. reducing atmosphere is passed through with 150sccm-180sccm speed in confined space；
4. atmosphere is continually fed into after 5min, and mould is heated by 30min-35min, is uniformly heating to 1020 DEG C -1050 DEG C；
5. reducing atmosphere is passed through speed adjust to 15sccm-20sccm, methane is passed through with 80sccm-100sccm speed；
6. continue 35min-40min, generate graphene inner membrance
2）It is prepared by outer layer
1. using the nitrogen of 3bar-5bar air pressure by 1）The graphene inner membrance and mould that 6. middle step obtains be cooled to 300 DEG C-
350℃；
2. configuration expoxy propane, oxirane, pentitol, potassium hydroxide solvent mixed solution, are passed through in confined space after atomization；
3. negative electrostatic field is loaded in confined space, keeps fog concentration constant by constantly spraying, to part slow cooling to room temperature,
Acquisition is compounded with the penta hydroxy group PPOX ether combined closely with graphene in graphene intimal surface；
4. immerse in the liquid environment containing diisocyanate resin and polymerize, that is, complete the production of polyurethane outer；
3）Contraception sleeve forming
1. mould is taken out, is put to the baking oven of -58 DEG C of temperature 50 C to drying；
2. piece surface is uniformly smeared into sealer, then heats to 45 DEG C -50 DEG C, be incubated 20min-30min, then done naturally
Dry and crimping, that is, obtain contraception sleeve blank；
3. the contraception sleeve blank 2. obtained to step carries out swelling, drying, inspection, Vacuum Package processing, that is, fine and close needed for obtaining
Inner membrance graphene sheath.
Compared with prior art, by adopting the above-described technical solution, the present invention has advantages below：Using in spraying
Copper on chemical vapor deposition graphene, cost is low, compact structure, and activity is high, in negative electrostatic field（According to my company's experiment feelings
Condition, penta hydroxy group PPOX ether and graphene are more easy to combine in negative electrostatic field, and this another patent with application simultaneously is not
Together）Active force under, it is easier to be tightly combined with the penta hydroxy group PPOX ether of one of outer polyurethane raw material, there is both
Machine is combined, and the polymerisation for then making polyurethane by suitable technique is directly carried out in graphenic surface, and what is be achieved in that is poly-
The adhesion of ether-based polyurethane and graphene will be much better than simple physical bonds；As a result of electrochemical preparation process, obtain
Internal layer be equilateral hexagon grain shape graphene film, because graphene is than by force and toughness is best in existing known materials
Material, also the invention provides enough strength supports and resisting breakage ability, to make the toughness and draw ratio of the present invention significantly
Improve, in addition, graphene also has the characteristics of high heat conduction, skin-friendly are good, its inner surface from into fixed equilateral hexagon shape,
Increase the frictional force between endosexine and skin, due to the material characteristic of graphene in itself, itself has actively absorption in flesh
The tendency on skin surface, strengthens the structural support of pleasant sensation to human body；Skin-material is based on polyurethane, according to prior art data,
EU has excellent combination property, makes the sheath outer layer of final molding and has extraordinary elasticity and intensity,
There is the soft pad buffering of certain polyurethane simultaneously, toughness can also substantially meet use requirement, in addition the structural support of graphene, toughness
Also superior to the natural latex products under equal conditions；Rationally, step is briefly easily realized, the system by the way of more extensive for technological design
The graphene taken is different from the electrically or optically demand graphene of high-precision production, its quality relative coarseness, at random, and is not individual layer
Structure, but the performance such as required intensity, toughness, heat transfer, the tear-proof of the present invention is entirely capable of being met, and cost is significantly less than high-precision
Spend graphene；The fact is also demonstrated that in the final finished sheath detection being combined into for the graphene with internal layer, is surveyed out
Indices are superior to general latex product, and wherein electrode test does not find electric leakage；Leak experiment maintains 10min and not found
There is drainage, higher than 1min as defined in standard；Airblasting experiment actual measurement filled volume is wanted up to 27L-33L higher than general
The 18L asked；Pressure 4.5-4.8kPa, far above the 2.0kPa that standard provides superpower sheath；Pull-off force average value 182N-
199N, higher than the 100N of standard requirement；There is no pin hole and visual defects.Compared with another patent of application simultaneously, the present invention
Intensity it is higher, wear-resisting, anti-corrosion, shock resistance is more preferable, the life-span is longer, but mouldability is relatively poor, production efficiency is relatively low, soft
Softness is poor, elongation percentage is relatively low.
