Abstract
The invention discloses a nitrile-butadiene rubber surgical glove and a preparation method of the nitrile-butadiene rubber surgical glove. The preparation method is simple in operation. By adopting the improved formula and process, the produced nitrile-butadiene rubber surgical glove has good tensile and elastic properties, and has breaking tenacity reaching up to more than 12.5N and tensile stretch more than 700%; furthermore the glove has good fatigue resistance, can be continuously used for more than 4 hours and cannot be worn out, thereby achieving the effect higher than that of the natural rubber glove.
Description
Technical field
The present invention relates to a kind of surgical glove, particularly a kind of acrylonitrile-butadiene rubber surgical glove, belong to the rubber technology field.
Background technology
Glove, owing to having the barrier protection effect, can be good at protecting the safety of user, have been widely used in people's productive life.The difference of purposes according to it, can be divided into medical gloves, industrial gloves and domestic purpose gloves; Difference according to manufacturing material used, can be divided into natural rubber gloves, butyronitrile gloves, PVC glove etc.Wherein, the butyronitrile gloves made from acrylonitrile-butadiene rubber latex, physical property is better than the PVC glove, and the oil resistant solvent resistance that has natural rubber gloves not possess, do not contain the protein that easily causes skin allergy in natural rubber, dress simultaneously Energy and comfort, therefore, in the application in a lot of fields in recent years, the trend that replaces natural rubber gloves is all arranged greatly.
But in the disposable surgical glove that Hospitals at Present is used, the overwhelming majority remains natural rubber gloves.Its main cause has two aspects: 1. the tensile property of acrylonitrile butadiene glove, elasticity are all poor than natural rubber latex; In standard GB/T 7543-2006 " disposable use antiseptic rubber surgical glove ", the tensile property requirement of also having stipulated glove, wherein to classification 1 glove, the namely requirement of natural rubber gloves is: the minimum 12.5N of breaking tenacity, percentage elongation 700%; To classification 2 glove, the requirement that comprises acrylonitrile butadiene glove is the minimum 9.0N of breaking tenacity, percentage elongation 600%; 2. the fatigue performance of acrylonitrile butadiene glove is weaker than natural rubber gloves, and lasting service time is longer, and the acrylonitrile butadiene glove glued membrane easily chaps, destroys.These are all the weak points that has at present butyronitrile gloves now.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of acrylonitrile-butadiene rubber surgical glove for above drawback, and the preparation method of this acrylonitrile-butadiene rubber surgical glove is provided, and this preparation method is easy to operate.Glove of the present invention, adopted improved composition and engineering, makes the acrylonitrile butadiene glove of producing by the method, and tensile property, elasticity all improve greatly, and more than the breaking tenacity of glove can reach 12.5N, percentage elongation was greater than 700%; And the unusual endurance of glove, put on one's gloves rear lasting use more than 4 hours glove can not destroy; Reached the effect no less than natural rubber gloves.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of preparation method of acrylonitrile-butadiene rubber surgical glove, its preparation method is as follows:
A. the acrylonitrile-butadiene rubber latex of use is flooded in preparation, by acrylonitrile-butadiene rubber, and colloid sulfur, zinc oxide, promoter ZDBC, promoter ZMBT, the abundant mix homogeneously of emulsifying liquid paraffin, the adjusting solid content is 25%-35%.
B. after mould is dried, first flood coagulant, coagulant be weight percentage lime nitrate or the calcium chloride solution of 8%-15%; Dry afterwards mould; Then mould floods the above-mentioned acrylonitrile-butadiene rubber latex prepared; Pass through again the high temperature drying of 120-140 degree centigrade, 20-40 minute; Finally cooling, handle sleeve is taken off from mould, just obtains finished product.
Above-mentioned a kind of acrylonitrile-butadiene rubber surgical glove, wherein, described acrylonitrile-butadiene rubber latex consists of the following composition, by mass fraction:
Above-mentioned a kind of acrylonitrile-butadiene rubber surgical glove, wherein, described acrylonitrile-butadiene rubber latex, preferably form, as follows according to the mass fraction:
Beneficial effect of the present invention is: the tensile property of a kind of acrylonitrile-butadiene rubber surgical glove of the present invention, elasticity all improve greatly, and breaking tenacity surpasses 12.5N, and percentage elongation is greater than 700%, reaches the requirement of classification 1 glove in GB GB7543-2006; The glove durability is good, put on rear lasting use more than 4 hours glove do not break, reached the effect no less than natural rubber gloves.
The specific embodiment
Below by specific embodiment, the specific embodiment of the present invention is described in further detail.
Colloid sulfur of the present invention is comprised of Cosan, barium stearate, Tissuemat E and water, Cosan: barium stearate: Tissuemat E: water is 3:2:2:4, by weight, during preparation, first by Cosan, barium stearate, Tissuemat E and water with 120R/min speed, stirred 10 minutes, and stirred and get final product.The Cosan granule is 180 orders.
