Description
Technical field
The present invention relates to a kind of preparation method of condom, relate to a kind of method adopting silk fibroin and Graphene to be mixed with condom.
Background technology
The condom overwhelming majority of selling on the market is at present all made with natural emulsion.The condom prepared due to caoutchouc latex can cause a lot of health problem.Anaphylaxis is had containing materials such as rubber producting plant protein to human body in natural emulsion, so the substitute products finding high-quality natural emulsion have been compeled in the whole world as pressing as a fire singeing one's eyebrows, such as: in recent years upgrade equivalent material polyisoprene, urethane has also been used as the substitute of natural emulsion, be used to the production of condom, but polyisoprene, the stretching thinness of polyurethanes or tough susceptibility do not improve, in use cis-1, 4-polyisoprene (natural emulsion composition), polyurethaness etc. are prepared in the process of condom at current general elastomer latex, many problems are it is found that, particularly condom, tensile strength is not high, human allergy, also have the condition of prevulcanized harsher.Natural silk fibroin has susceptibility and the good feature of pro-skin texture, and fibroin graphite mixture condom uniquely to reach " not there is not sense " high quality condom.
C08L9/00 (2006.01) I discloses the preparation method that a kind of rubber and plastic synthesizes ultra-thin condom.That embody is the preparation method that a kind of rubber and plastic synthesizes ultra-thin condom, it take synthetic polyisoprenes as matrix, by adding aqueous polyurethane, a small amount of natural rubber latex, synthesize a kind of composite high-molecular material and prepare condom, the ultra-thin synthesis condom of this development & production, there is ultra-thin feature, increase the comfortableness used, physiologically acceptable safety, physical strength is high, but also there are some defects, is mainly manifested in: flexibility and the extendability of product are poorer than natural gum, product cost and use cost are all higher, only single solution thinness problem.
C08L7/02 (2006.01) I discloses a kind of preparation method of soft condom.Pure isoprene rubber latex and natural rubber latex mixing is utilized to improve the quality of condom products, will greatly improving of explosion volume ratio pure natural latex condom before mixing latex condom is aging, thus the softness of goods improves, and burstpressures significantly improves than the simple polyisoprene latex condom that uses, aging rear product performance can keep higher level again, thus make product meet the requirement of international standard and the comfort of human consumer, also only single solution soft comfortable.
The current research at international and domestic all condoms and invention are only confined to natural emulsion or synthetic polyisoprene, polyurethane material in sum, and essence equivalent material does not invent the raw material of pure natural, could not revolutionaryly break through.Technology of preparing or application are also single solution thinness or single soft comfortable degree problem
Summary of the invention
The present invention seeks to revolutionary character and overturn existing vegetable rubber latex of international and domestic centuries and synthetic materials polyisoprene, under the old material prepared technology such as urethane and applicable cases, adopt natural mulberry silk extraction silk fibroin natural biologic material and Graphene Two-dimensional Carbon atom mixture technology of preparing, a kind of method adopting fibroin graphite latex to prepare condom is provided, the method can implement suitability for industrialized production easily, the fibroin graphite latex condom skinfeel adopting the inventive method to prepare is extremely soft, tough, use brings super to cause " not there is not sense " comfortable sensation.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Adopt silk fibroin and Graphene to be mixed with a method for condom, comprise the following steps:
A1: under 20-28 DEG C of condition, silk fibroin latex and Graphene stirring at low speed under 20-28 DEG C of condition is made to carry out mixture in 12 hours, the rotating speed of described stirring at low speed is 40-50rpm, control in mixture process total solids level 60%, pH value is at 3.8-7.0, obtain mixture latex, maturation parked by mixture latex; Promotor in described compounding ingredients uses environment-friendly type sulfuration bag promotor, and described environment-friendly type sulfuration bag promotor is that sulphur and zinc oxide, thiuram, oxidation inhibitor combine.
A2: flood in the mixture latex of the condom mould of suitable shape in steps A 1 after slaking, takes out described condom mould after dipping and dries under 85-90 DEG C of condition, to form glued membrane on described condom mould
A3: the glued membrane that condom mould described in steps A 2 is formed is carried out in conventional crimping, oven dry, swelling, off-type, foam washing after powder, processed, drier sulfuration under 100-120 DEG C of condition, to form condom,
Further, in steps A 1, maturation 5-7 days parked by mixture latex.
Further, in steps A 2, steeping process carries out under 20-28 DEG C of condition.
Further, be no less than and carry out twice dipping.
Further, in steps A 2, after each dipping, all at 85-90 DEG C, dry 5--10 minute, until the glued membrane on described condom mould is transparent.
Further, in steps A 3, the time of the dry sulfuration of described glued membrane is 45 minutes.
Understand as this area, the silk fibroin emulsion of extraction must and the compounded materials mixture of appropriate graphite alkene, to make the mixture latex obtained fully solidify, thus obtain glued membrane, a kind of widespread use, typical mixture latex formulations is as follows:
| Batching function | Solid-state material proportioning (weight part) |
| Silk fibroin latex | 0.75-0.85 |
| Graphene | 0.15-0.25 |
| Stablizer | 0-1.5 |
| Vulcanizing agent | 0.5-1.6 |
| Sulphur | 0.5-1.0 |
| Zinc oxide | 0.1-0.5 |
| Promotor | 0.1-1.5 |
| Anti-aging agent | 0.1-1.0 |
| Oxidation inhibitor | 0.5-1.0 |
| Ph conditioning agent | 0-0.5 |
| Deionized water | (determined by total solids level) in right amount |
In upper table, liquid proportioning refers to the solid-state mixing when material carried out under liquefied of batching.
In above-mentioned formula, multiple compound can be comprised.Above-mentioned formula is the exemplary of essential substance, is suitable for silk fibroin latex and Graphene mixture usage.
The combination of any suitable promotor or linking agent can be used in formula.Preferred use environment-friendly type vulcanization accelerator, this promotor can significantly improve the stretching toughness of glued membrane and ultra-thin rate, and wherein environment-friendly type vulcanization accelerator can select the combination of sulphur, zinc oxide, sulfuration bag and thiuram.
The inventive method can produce tough, ultra-thin high-quality condom, makes it have excellent physical properties, and following table is performance perameter table of the present invention:
As can be seen from the above table, the fibroin graphite condom adopting the inventive method to prepare has good performance in burstpressures, explosion volume, in addition ageing-resistant performance compared with natural emulsion condom, polyisoprene condoms etc., this fibroin graphite latex condom feel extremely softness, pro-skin, brings the sensation of ultimate attainment comfortable " not there is not sense " to user simultaneously.
Beneficial effect of the present invention is for can implement suitability for industrialized production easily, and the fibroin graphite latex condom skinfeel adopting the inventive method to prepare is extremely soft, tough, uses and brings super to cause " not there is not sense " comfortable sensation.The inventive method need not carry out the mixture of fibroin graphite latex and the dipping of condom mould at low temperatures, and the condom prepared also can reach required stretching toughness and ultra-thin degree.
