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. ON, 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

Abstract

The invention discloses an allergy-free rubber glove which comprises a rubber latex and an allergy-free active component. The rubber glove is characterized in that the rubber latex is composed of the following components in parts by weight: 100 parts of natural rubber, 6-10 parts of emulsified liquid paraffin, 0.4-1.2 parts of colloid sulfur, 0.4-1.0 part of zinc oxide, 0.3-0.5 part of accelerator ZDBC, 0.3-0.5 part of accelerator ZMBT and 0.7-1.5 parts of allergy-free active component. The allergy-free active component is composed of a tropaeolum extract and a centella extract in a weight ratio of (1-3):(2-4). The allergy-free active component added into the matrix of the operating glove can avoid the symptom of allergy and enhance the safety performance of the operating glove.

Description

technical field [0001] The invention relates to surgical gloves, in particular to a hypoallergenic surgical glove. 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. [0003] At present, nitrile gloves made of nitrile rubber latex have better physical properties than PVC gloves. Therefore, in recent years, they have a tendency to replace natural rubber gloves in many fields. However, among the disposable surgical gloves currently used in hospitals, the vast majority are still natural rubber gloves. There are two main reasons for this: 1. The tensile properties and elasticity of nitrile rubber gloves are wo...
