Description
Technical field
The invention belongs to contraceptives, and in particular to a kind of latex prophylactic for being added to sodium hyaluronate.
Background technique
Sheath is common family planning articles in people's daily life, sperm and ovum when being mainly used for separating human sexuality
The combination of son, prevents from being pregnant.In the modern life, with the propagation and sprawling of the various venereal diseases such as AIDS, in sexual life, Nan Xingpei
Wearing condom is a kind of most simple and effective means to venereal disease is prevented.
Sodium hyaluronate is one of molecule most hydrophilic in natural, has many benefits to human body, can improve skin-nourishing generation
Thank, make skin it is tender, it is smooth, go wrinkle, increase elasticity, prevent aging, be the promotion of good Transdermal absorption again while moisturizing
Agent is referred to as " natural moisturizer ".Sodium hyaluronate can be found in most cells of human body, but mainly with higher dense
Degree is present in skin histology, and almost 50% sodium hyaluronate is present in skin histology in human body.Sodium hyaluronate can help skin
A large amount of moisture is drawn, skin is made to keep smooth and flexible, while skin is due to keeping young containing a large amount of sodium hyaluronate
Health.But with the influence of the factors such as the growth and nutrition at people's age, sunshine and environment, skin generates the ability of sodium hyaluronate
It is gradually reduced, therefore the content of sodium hyaluronate can gradually decrease in skin, causes skin dehydration, wrinkles and follow the string, make one table
Skin aging.Have in the prior art since the compatibility of sodium hyaluronate is good and is added frequently as lubricating additive.
Natural emulsion (raw rubber, natural rubber) is obtained from the rubber tree of cultivation, has good filming performance, wet
Gel strength is high, and good mechanical properties, mechanical stability is high, and color is pure white, and foam stability is good.Natural emulsion is by processing
Afterwards, there is very excellent comprehensive performance, be current most popular sheath, due to the sheath of caoutchouc latex preparation
Many health problems can be caused.There is allergic reaction to human body containing substances such as rubber plant protein in natural emulsion, so seeking
The substitute products of high-quality natural emulsion are looked for compel in the whole world as pressing as a fire singeing one's eyebrows, such as: alternative materials polyisoprene, poly- ammonia are updated in recent years
Ester is also utilized as the substitute of natural emulsion.
By force, lubricity is good for sheath " natural sense ", effectively repairs vaginal mucosa and is damaged, improve vaginal relaxation, restores vagina
Tight can promote pleasant sensation, make sexual life more harmonious, promote emotion between husband and wife；It is more reduced skin damage simultaneously
Wound reduces the harmful microorganisms such as bacterium, virus to the erosion chance of human body；Effectively reduce the breakage of condom, reduce it is unexpected by
Pregnant probability.
Currently, a kind of chitosan of the existing Patent No. CN201810938414.7 patent name for addition in sheath
The production application process of class water-soluble lubricating liquid is disclosed dissolved with sodium hyaluronate pulvis, and agitated uniform technique makes entire moisturizing
System is moist, thick and heavy, non-greasy, then lubricating fluid is equably applied on sheath glue film, or is added dropwise on sheath, makes
Condom products more lubricate, and have hemostasis, anti-inflammatory, promote wound healing, skin is kept to moisten, smooth, prevent dry and send out
It is dark and other effects, but dissolution of the lubricating fluid of the sheath through pulvis raw material, smear, it is easy that agglomerating, dispersion is uneven, causes
Waste of raw materials increases the disadvantages of cost.
Summary of the invention
The latex prophylactic provided by the invention for being added to sodium hyaluronate, can play the function of lubrication skin care, and sodium hyaluronate is effective
It is attached to vagina skin surface, long-time service can improve vaginal relaxation, restore vagina tight.
The latex prophylactic provided by the invention for being added to sodium hyaluronate includes the common natural rubber of first layer from the inside to the outside
Layer, the second layer are high flexibility layer and the common caoutchouc layer of third layer；The second layer is that high flexibility layer includes flaky silicic acid magnalium
Powder, sodium hyaluronate, sodium lignin sulfonate and natural emulsion.
The latex prophylactic for being added to sodium hyaluronate is prepared by following steps:
Step 1, natural rubber latex is prepared, natural emulsion, dispersing agent, thickener are mixed and stirred in parts by weight
It is even to obtain the final product；
Step 2, high flexibility natural rubber latex is prepared, sodium hyaluronate and sodium lignin sulfonate are stirred in parts by weight mixed
It closes, suitable water is added and carries out emulsion dispersion；200~800nm flaky silicic acid magnalium powder, stirring is added；Then it is added natural
Latex stirs at a certain temperature to obtain the final product；
Step 3, natural rubber latex step 1 obtained is injected separately into first of glue groove and third road glue groove, will
The high flexibility natural rubber latex that step 2 obtains is injected into second glue groove；
Step 4, the condom mould after cleaning-drying is placed on condom manufacture line, condom mould is made to immerse the
One of glue groove impregnation, moving ahead reaches baking zone drying, forms first layer caoutchouc layer；
Step 5, second glue groove impregnation, dry immersion after impregnation are immersed through the condom mould after step 4 gluing
And third road glue groove, dry demoulding again, forms the latex prophylactic for being added to sodium hyaluronate after glue.
Further, the flaky silicic acid magnalium powder is the 2-5wt% of high flexibility natural rubber latex.
Further, the sodium hyaluronate is the 0.1-0.2wt% of high flexibility natural rubber latex.
Further, the sodium lignin sulfonate is the 0.1-0.5wt% of high flexibility natural rubber latex.
Further, the time that the condom mould enters three glue grooves is 6-12s.
Further, temperature described in the step 2 is 60-65 DEG C, improves the compatibility and hydrophily of sodium hyaluronate.
Further, it is 24~28 degrees Celsius that optimum temperature is impregnated in the step 4, and must not impregnate less than 2 times.
The latex prophylactic provided by the invention for being added to sodium hyaluronate is effectively attached to vagina skin surface, is used for a long time
To the function of lubrication skin care, vaginal relaxation can be improved, restore vagina tight；Lubricity is high, reduces skin injury, reduces thin
Erosion chance of the harmful microorganisms such as bacterium, virus to human body；Middle layer is added flaky silicic acid magnalium layer and inserts material, between nanometer layer
Opposite sliding the flexibility of latex can be improved, there is better tear resistance and elasticity, draftability is good.
