On the biocide and first latex layer, be coated with the liquid latex second layer.
Sixth aspect present invention proposes to contain the latex material manufacture method on biocide barrier layer, and its step comprises:
On model, be coated with the biocide layer that can be used as the liquid latex coagulant, be selected from dextran sulfate, zephiran, betadyne, gentian violet, acriflavine and acridine dye, mercurochrome, silver salt and bluish-green algae extract, this biocide is concentration and is essentially the 0.10-5wt% liquid state; With
Be coated with liquid latex layer on the biocide layer that is applied on this model, coating result reaches the weight ratio of killing thing kill agent liquid coating and latex layer and is essentially 0.05-0.3.
Biocide can be used as the liquid latex coagulant among the present invention, can be in a liquid state to be applied on the latex, and the weight ratio that concentration is essentially 0.10-5wt% and biocide liquid coating and latex coating is essentially 0.05-3.
The used biocide of the present invention is selected from dextran sulfate, zephiran, betadyne, gentian violet, acriflavine and acridine dye, mercurochrome, silver salt and bluish-green algae extract.
Among the present invention biocide can spray or dip-coating and can be when the latex proofing layer be wet gel state coating.Available water leaching latex proofing layer and before being coated with second latex layer, be applied to biocide liquid bone dry basically on the latex proofing layer also before being coated with liquid state.Film of the present invention can be one deck latex, one deck biocide, and biocide can be coated on the model or is coated on the latex layer that is applied on the model.The biocide layer also can be between the two-layer latex.
More particularly, the present invention relates to form chemical barrier layer to stop diseases induced microorganism and other hazardous agents by latex or other material, as natural cortex, natural rubber, solvent injects film, the method for the film that elastomer and polymer form through liquid curing.For simplicity, preferred embodiment is the example explanation with the latex material.Latex material can be made into gloves, sheath, barrier film, slippers, overshoes, sterilization band, conduit, latex or plastic tube, diaphragm, valance, internal organ hole, mouth mask, baby's nipple, stomach nasal tube, the nose stomach tube, kidney shunt, tooth dam, tooth rubber wooden handcuff tool, subclavian vein and artery wooden handcuff tool, colonic diversion bag or any other products.These products generally are used for the involutory of human or animal's skin.
This paper " biocide " guide disease characteristic or harmful characteristic become essentially no any effectiveness immediately behind contact or microorganism or hazardous agents contact Biocidal agent material.Several biocides that can exemplify are dextran sulfate, nonoxynol-9, zephiran, betadyne, gentian violet, acriflavine and acridine dye, mercurochrome, silver salt and bluish-green algae extract.In addition, the table of a series of suitable biocides and the application submit to and simultaneously as the application's a part.
Latex products, as gloves and sheath, Chang Jing once or secondary dipping process make.Require the model of latex products shape to cover coagulant earlier, sedimentary facies is worked as thick continuously even latex layer on model again.Coagulant is soaking model suitably for a long time after the drying on the model in the liquid latex urn, thereby can form latex film on model surface, allows latex become wet gelling or viscosity attitude, and leaching in gel state is placed on the hot water washing lotion or bathes.Any residual ammonia or potassium hydroxide that washing lotion is removed coagulant and may be existed.In order to increase latex thickness, this method can repeat closely to form second layer latex film on ground floor latex.In general the second layer is thinner than ground floor.
By following test the biocide barrier layer is added in the latex products.After model immerses in the liquid latex for the first time and uses the hot water leaching in the usual way, model (liquid latex is wet gel state) is immersed in the gentian violet liquid concentration 0.33wt% in the water.Allow biocide liquid be coated with liquid latex.Then with biocide liquid coating drying.Afterwards, again model is immersed in the liquid latex urn, but also leaching, the dry then Bulk coat curing that makes on the model.
Usually the thickness that reaches when as if biocide can be used as second coagulant and makes second latex layer than inanimate object kill agent liquid among the present invention is much thick.
1.5wt% gentian violet liquid also is used for this method in the water, and its uniformity is inferior a little with regard to coating layer thickness.But water or water and alcohol are also with also being used for this method up to about 5wt% gentian violet liquid in other cosolvent, and its uniformity is inferior a little with regard to coating layer thickness.But water or water and alcohol also can be used for this method effectively with the concentration up to about 5wt% gentian violet in other cosolvent.
Find that the maximum coating amount of biocide liquid that is reached by the wet gel latex that is applied on the model is about 0.2g/g latex.
Biocide it is believed that in conjunction with and permanent being diffused in the latex surface, thereby filled the hole in the latex basically and remedied other defective.
Except dip-coating, also can or otherwise be coated onto on the wet gel breast among the present invention the spray of biocide liquid.
Although the above-mentioned specific embodiments of the present invention that illustrated should be seen, the those of ordinary skill in the present technique field also can easily be made various improvement and conversion, and these improve and conversion also belongs to design of the present invention and protection domain certainly.Therefore, the scope of the invention is defined as follows, and is not only as mentioned above.
