Abstract
The invention discloses a method for preparing neoprene condoms. Neoprene is used as a substrate for the neoprene condoms, and the neoprene, zinc oxide, sulfur, N, N'-diphenylthiourea, 1, 3-biphenyl guanidine and antioxidants are synthesized to obtain the neoprene condoms. The method for preparing condom products by the aid of the neoprene instead of original natural rubber latex processes has the advantages that the condom products are good in oil resistance and wide in service range, and influence on the performance of the products due to different types of lubricating fluid for human bodies can be prevented while natural rubber latex is intolerant to petroleum-based lubricating fluid; the products are good in stability, and deterioration of the performance of the products can be prevented even after the products are stored for five years; the products are good in compactness and virus penetration resistance; the neoprene condoms do not contain toxic and harmful cancerogen such as nitrosamines; the ultrathin condoms can be made of raw materials with good performance; the neoprene does not contain water-soluble proteins, and accordingly allergic reaction of the human bodies can be prevented.
Description
Technical field
The present invention relates to family planning apparatus production technical field, replace, particularly to a kind of neoprene, the method that Heveatex prepares condom.
Background technology
Condom has a lot of primary raw material to be Heveatex, it is mainly disadvantageous in that: raw-material storage stability difference and tolerance to cold are poor, make owing to the prices of raw materials are expensive product cost and use cost all higher and natural latex products exists following defect: the compactness of product is poor, and anti-virus penetration capacity is below 90%; Loss of properties on aging, product hydraulic performance decline in storing process is obvious, there is product and causes the risk of product failure due to storage problem, hydraulic performance decline more than 50% when storing 5 years; React simultaneously because product contains water miscible protein easily caused by human allergy's property; The body lotion of oil base class can not be used, otherwise can cause the chain rupture of product macromolecular chain, lose efficacy even at product breakage in 10 minutes.
Summary of the invention
The invention aims to the shortcoming overcoming above-mentioned background technology, a kind of method that neoprene replaces Heveatex to prepare condom is provided, purpose is to replace Heveatex with neoprene, meet people to healthy demand, the comfort of product is the same with Heveatex, but product is without the carcinogen such as anaphylactogen and nitrosamine, fully demonstrate safety and the effectiveness of medical apparatus and instruments, reduce society's expenditure to medical expense.
The preparation method that the technical scheme is that a kind of neoprene condom, with neoprene for substrate, each raw material components quality proportioning:

Sulphur concentration 50% dispersion 1.5 parts
N,N' diphenyl thiourea concentration 50% dispersion 1.5 parts
1,3-xenyl guanidine concentration 50% dispersion 1.5 parts
Antioxidant concentration 50% dispersion 1.2 parts
Described antioxidant is LOWINOXCPL;
1) sulfur adjustment type polychloroprene latex and non-sulfur adjustment type polychloroprene latex are mixed in the ratio of 8:2, after stirring 15 minutes, make neoprene;
2) in the neoprene prepared, add zinc oxide, sulfur, N, N'-rhenocure CA, 1,3-xenyl guanidine 1.5 parts, antioxidant, continue stirring 30 minutes;The dipping neoprene latex raw material made, display 48 hours stand-by;
3) mold clean preheating;
4) dipping neoprene latex: first time impregnation, neoprene latex total solids content 30 �� 5%, temperature 30 �� 5 DEG C, impregnation after cure, curing temperature 130 �� 10 DEG C, 5 minutes time; Second time impregnation, again impregnates, neoprene latex total solids content 40 �� 5%, glue temperature 30 �� 5 DEG C on first time dipping basis, and impregnation thickness vulcanizes, curing temperature 130 �� 10 DEG C, 5 minutes time; Carrying out third time impregnation on the basis of second time impregnation and make just finished product, condition is identical with second time impregnation;
5) crimping sulfuration: first finished product is carried out crimping after cure, curing temperature 130 �� 5 DEG C, 10 minutes time;
6) electric-examination, detection voltage is 500V;
7) leaching interleaving agent and drying: leaching interleaving agent post-drying, interleaving agent mass concentration is 15%;
8) batch and the demoulding.
Above-mentioned neoprene latex total solids content is regulated by pure water or vulcanized rubber.
Described interleaving agent is white carbon. Dipping interleaving agent post-baking temperature is 80 �� 5 DEG C, 5 minutes time.
The invention has the beneficial effects as follows: use neoprene to replace former Heveatex technique to prepare condom goods and have the following advantages: product oil resistivity is good, use various body lotion all without the performance generation impact on product, use scope is wide, and Heveatex is just weak to oil base class lubricating fluid; The good stability of product, after storing 5 years, the performance of product does not decline; The good anti-virus penetration capacity of the compactness of product is good; Without poisonous and hazardous Carcinogenic Nitrosamines etc.; Material property can make well ultra-thin condom; Neoprene will not cause human allergy's property to react without water soluble protein.
Detailed description of the invention
The present embodiment is the preparation method of a kind of neoprene condom, and it is with neoprene for substrate, makes raw material by following quality proportioning:
Neoprene weight by dry rubber amount 100 parts
Zinc oxide concentration 50% dispersion 5 parts
Sulphur concentration 50% dispersion 1.5 parts
N,N' diphenyl thiourea concentration 50% dispersion 1.5 parts
1,3-xenyl guanidine concentration 50% dispersion 1.5 parts
Antioxidant concentration 50% dispersion 1.2 parts
Antioxidant is LOWINOXCPL, chemistry polymer grade (space) hindered phenol by name. Above dispersion is all outsourcing, and manufacturing enterprise is Bangbu Rui Jie Science and Technology Ltd..
Concrete preparation method is as follows:
1) sulfur adjustment type polychloroprene latex and non-sulfur adjustment type polychloroprene latex are mixed in the ratio of 8:2, after stirring 15 minutes, make neoprene.
2) neoprene 100 parts prepared is taken, add the zinc oxide 5 parts of concentration 50% dispersion wherein, the sulfur of concentration 50% dispersion 1.5 parts, the N of concentration 50% dispersion, N'-rhenocure CA 1.5 parts, 1, the 3-xenyl guanidine 1.5 parts of concentration 50% dispersion, 1.2 parts of the antioxidant of concentration 50% dispersion, continues stirring 30 minutes; Good neoprene latex raw material made above enters condom manufacture line after displaying 48 hours and carries out dip forming processing.
