example 1

[0016] A preparation method of medical gloves blended with natural rubber and nitrile rubber, the preparation method is as follows: firstly prepare rubber latex for dipping. Take 70 parts of natural rubber latex, 30 parts of nitrile rubber latex, 1.0 part of dispersant N, 0.6 part of stabilizer sodium polyacrylate, and mix well; add 1.0 part of sulfur, 1.0 part of zinc oxide, and 0.7 part of accelerator ZDEC, 1.9 parts of titanium dioxide, 0.6 parts of potassium hydroxide, and adjust the solid content to 28%. After the ceramic mold is cleaned and dried, it is first dipped in a calcium nitrate solution with a concentration of 10% by weight, taken out, dried, and dipped in the latex; then crimped, then immersed in warm water at 45 degrees Celsius for 2 minutes, taken out, and after 30 minutes at 125 degrees Celsius Drying, cooling, and demoulding to obtain the finished product.

Embodiment 1

[0017] The performance data of a kind of nitrile rubber surgical glove prepared in embodiment 1 is as follows, and is detected by the standard of GB10213-2006.

[0018] The performance data of a kind of acrylonitrile-butadiene rubber surgical gloves prepared by the present invention

example 2

[0021] A preparation method of medical gloves blended with natural rubber and nitrile rubber, the preparation method is as follows: firstly prepare rubber latex for dipping. Take 65 parts of natural rubber latex, 35 parts of nitrile rubber latex, 0.8 parts of dispersant N, 0.8 parts of stabilizer sodium polyacrylate, and mix well; add 0.6 parts of sulfur, 1.2 parts of zinc oxide, 0.5 parts of accelerator ZDEC, titanium dioxide 1.5 parts, 0.8 parts of potassium hydroxide, and adjust the solid content to 25%. After the ceramic mold is cleaned and dried, it is first dipped in a calcium chloride solution with a concentration of 8% by weight, taken out, dried, and dipped in the latex; then crimped, then immersed in warm water at 50 degrees Celsius for 2 minutes, taken out, and passed through 120 degrees Celsius for 35 minutes Drying, cooling, demoulding, and finished products.

Abstract

The invention discloses a natural rubber and nitrile rubber blended medical glove and a preparation method thereof. The good tensile property and the soft hand feeling of a latex glove are possessed by the natural rubber and nitrile rubber blended medical glove. The rubber medical glove made by adopting the method has a breaking tenacity exceeding 7.0N and an elongation of above 650%, accords with requirements of GB 10213-2006 Disposable Medical Rubber Examination Gloves, and has the characteristics of soft hand feeling, use convenience, comfortableness, and very good oil and solvent resistances.

Description

technical field [0001] The invention relates to a medical glove, in particular to a medical glove blended with natural rubber and nitrile rubber and a preparation method thereof, belonging to the technical field of rubber gloves. Background technique [0002] Disposable gloves have been widely used in modern production and life. According to the different materials used in manufacturing, they can be divided into natural rubber gloves, nitrile gloves, PVC gloves and so on. These gloves can well protect users from foreign pathogenic microorganisms or toxic and corrosive chemicals. Among them, although PVC gloves are cheap, their overall performance is poor, which limits their application to a certain extent. For better protection, people prefer natural rubber gloves and nitrile rubber gloves. Among them, natural rubber gloves have the advantages of soft hand feeling and good tensile properties, but their chemical resistance and solvent resistance are poor; nitrile gloves hav...
