Problems solved by technology

There are two main reasons for this: 1. The tensile properties and elasticity of nitrile rubber gloves are worse than those of natural rubber latex; the national standard GB7543-2006 "Disposable Sterilized Rubber Surgical Gloves" also stipulates the stretching properties of gloves. Performance requirements, among which the requirements for category 1 gloves, that is, natural rubber gloves are: the minimum tearing force is 12.5N, and the elongation is 700%; the requirement for category 2 gloves, including nitrile rubber gloves, is the minimum tearing force of 9.0N , the elongation rate is 600%; 2. The fatigue resistance of nitrile rubber gloves is weaker than that of natural rubber gloves, and the continuous use time is longer, and the film of nitrile rubber gloves is prone to cracking and damage

example 1

[0019] A kind of preparation method of acrylonitrile-butadiene rubber surgical gloves, its preparation method is as follows: first prepare the acrylonitrile-butadiene rubber latex that impregnation is used, formula is in dry part, by mass part: 100 parts of acrylonitrile-butadiene rubber, 0.8 part of colloidal sulfur, oxidized 0.8 parts of zinc, 0.4 parts of accelerator ZDBC, 0.4 parts of accelerator ZMBT, 8 parts of emulsified liquid paraffin, and finally adjust the solid content to 32%. After the ceramic mold is cleaned and dried, it is first dipped in 13% calcium nitrate solution, taken out, dried, and dipped in the nitrile rubber latex; then crimped, then immersed in warm water at 45 degrees Celsius for 2 minutes, taken out, and after 130 degrees Celsius for 30 minutes Drying, cooling, and demoulding to obtain the finished product.

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 [0001] The invention relates to a surgical glove, in particular to a nitrile rubber surgical glove, which belongs to the technical field of rubber. Background technique [0002] Gloves have been widely used in people's production and life because of their barrier protection and can well protect the safety of users. According to its different uses, it can be divided into medical gloves, industrial gloves and household gloves; according to the different materials used in manufacturing, it can be divided into natural rubber gloves, nitrile gloves, PVC gloves and so on. Among them, nitrile gloves made of nitrile rubber latex have better physical properties than PVC gloves, and have oil and solvent resistance that natural rubber gloves do not have. They do not contain proteins in natural rubber that are prone to skin allergies, and are convenient and comfortable to wear. Therefore, in recent years, there is a tendency to replace natural rubber gloves in applicati...
