Abstract
The invention discloses a pair of medical gloves prepared from natural rubber and a production method thereof. The pair of medical gloves has breaking tenacity more than 8.0N and elongation higher than 750%, and the requirements of GB10213-2006 Disposable Medical Latex Examination Gloves can be met; the pair of medical gloves prepared from the natural rubber has soft handfeel and is convenient and comfortable to use; meanwhile, the medical gloves have good oil resistance and solvent resistance.
Description
Technical field
The present invention relates to a kind of medical gloves, particularly a kind of natural rubber medical gloves and preparation method thereof, belongs to rubber gloves technical field.
Background technology
Disposable use gloves have been widely used in modern production life, and the difference according to manufacturing material used, can be divided into natural rubber gloves, butyronitrile gloves, PVC gloves etc.These gloves, can well protect user to avoid external pathogenic microorganism or the poisonous harm that has corrosion chemical.Wherein, although PVC gloves are cheap, yet over-all properties is poor, has limited to a certain extent application; Butyronitrile gloves has good oil resistant, solvent resistance, but the elasticity of gloves is not enough.In order to obtain better protection effect, people tend to natural rubber gloves more, the advantage that natural rubber gloves has is soft, tensile property is good, but the chemicals-resistant of gloves, solvent resistance are poor, therefore,, for the improvement of natural rubber gloves, more and more receive people's concern.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of natural rubber medical gloves for above drawback, and these gloves will have tensile property that emgloves is good and soft feel, possesses again oil resistant, solvent-proof advantage simultaneously.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A medical gloves, comprises the steps:
The latex of A, preparation dipping use: get natural rubber latex, gas-phase silica, dispersion agent N, stablizer sodium polyacrylate, fully mixes; Add again sulphur, zinc oxide, promotor ZDEC, clorafin, potassium hydroxide and calcium hydroxide, adjusting solid content is 18%-35%;
B, mould first flood peptizer after drying, and the peptizer concentration that is weight percentage is nitrocalcite or the calcium chloride solution of 6%-16%; Dry afterwards mould; Then mould floods the above-mentioned latex preparing; Pass through again the high temperature drying of 110-130 degree Celsius, 20-40 minute; Finally cooling, handle sleeve is taken off from mould, just obtains finished product.
Natural rubber medical gloves prepared by aforesaid method, wherein, described dipping latex, its moiety is as follows by dry part massfraction:
Beneficial effect of the present invention is: the rubber medical glove that uses the party's legal system, breaking tenacity surpasses 8.0N, elongation is greater than 750%, reaches the requirement of the disposable use medical grade rubber of GB10213-2006 < < latex examination gloves > >; Gloves are soft, easy to use comfortable; There are good oil resistant, solvent resistance simultaneously.
Embodiment
