Abstract
The invention discloses a pair of latex gloves which is provided with polyurethane emulsion inner coating, the surface has hemp shaped projections, finger portions and palm portions takes on special curved shape, wherein polyurethane emulsion belongs to the cationic system. The gloves can prevent medical allergy and can increase the friction between gloves and held objects in order to prevent appliances from dropping off when the gloves are applied in the process of medical diagnosis and operation.
Description
Technical field
The present invention relates to a kind of polymer undercoat, surface of having and have the latex glove that numb shape projection, finger and palm are the bending design, belong to protective articles technical field in medical diagnosis and treatment and the surgical procedure.
Background technology
The medical operation of natural rubber or tartan and latex examination gloves are by widespread production and use.Owing to directly be worn on hand, this gloves need with inner surface that hand contact on through special lubricated so that wearing.Normally used lubricant comprises powder, such as traditional talcum powder and starch.But because partly the crowd is to pulvis allergy, powder is again the carrier of some microorganisms and malignant bacteria in addition, obviously uses just to be not suitable in the Operation theatre of high purification.So just press for a kind of just wearable gloves of lubricant that do not rely on.Therefore the gloves with smooth surface new technique that generated by polyether polyols with reduced unsaturation and the reaction of natural rubber latex generation glue connection arise at the historic moment.The inner surface of this gloves is smooth, has reduced the frictional coefficient between rubber gloves and the personnel of wearing skin when contacting with staff, therefore clearly improves wearable property.
At present the shape of domestic production medical gloves mostly is the straight hand shape of light face greatly, and because of this hand shape does not meet people's hand physiological characteristic, therefore long-time the wearing is easy to cause hand fatigue, has slick surface little because of friction again, the landing that is easy to produce apparatus.My company is for many years according to Chinese hand characteristics and requirement, designed to meet the pitted skin bending medical gloves that Chinese use.
Summary of the invention
The invention provides a kind of polyaminoester emulsion undercoat, outside surface of having and have the rubber gloves that numb shape projection, finger and palm are special bending design.
Described polyaminoester emulsion is by in emulsion solids branch gross weight, the aliphatic polyisocyante of the polyester of 30～70 weight parts or polyester polyol, 20～50 weight parts, 5-20 weight part dibasic alcohol chainextender, the cationic expansion of 2-10 weight part connect agent and form, add acetone in the reaction and regulate viscosity, after finishing, reaction neutralizes with acid, add emulsifying water, add the back again and expand even agent reaction, remove solvent acetone at last and obtain.
Described polyester or polyester polyol be selected from following one or more: polycaprolactone, poly-hexanodioic acid-1,4 butyleneglycols, poly-adipate glycol-1,4 butanediol ester glycol, poly-hexanodioic acid 1,6 hexylene glycols, polyethylene glycol adipate.
