Problems solved by technology

[0003] At present, there are many varieties of nitrile gloves. Nitrile gloves are mainly made by dipping nitrile latex, molding, vulcanization, surface treatment, dust-free cleaning and other processes. They have excellent puncture resistance, chemical resistance, friction resistance and Durable wearing force, chlorine washing is generally required in the demoulding process after nitrile gloves are molded to remove the stickiness of the glove surface and facilitate the wearing of gloves, but this will increase the chlorine content in nitrile gloves, and when the operator wears nitrile gloves When the gloves are used for specific process operations, a small amount of chlorine elements will penetrate into the gloves, which will affect the accuracy of the operation; in addition, dust particles will adhere to the surface of the nitrile gloves during preparation, and the falling of dust particles will also have a great impact on the performance of the produced products. Great impact, so the cleanliness of nitrile gloves also need to be strictly controlled

Abstract

The invention discloses a preparation method of butyronitrile gloves, and belongs to the technical field of butyronitrile gloves. The preparation method comprises following steps: a rubber latex raw material of the butyronitrile gloves is prepared; a hand mould is subjected to acid pickling, a first time of water washing, alkali washing, a second time of water washing, drying, and chlorine washing, is immersed in a coagulating agent solution for immersion, and is subjected to impregnation in the rubber latex raw material; and obtained rubber film is subjected to washing and demoulding. According to the preparation method, only one time of chlorine washing is carried out before hand mould impregnation, so that the surfaces of the butyronitrile gloves obtained via impregnation moulding are smooth, the butyronitrile gloves are convenient to wear, no adhesion is caused, processing process is simplified, and the chlorine content of the butyronitrile gloves is reduced greatly; and in addition, DI water is used for washing so as to remove particles and surface ions on the surfaces of the butyronitrile gloves, and the cleanliness of the butyronitrile gloves is improved.

Description

technical field [0001] The invention relates to the technical field of nitrile gloves, in particular to a preparation method of nitrile gloves. Background technique [0002] With the improvement of precision requirements of high-tech products, more and more products are required to be produced, packaged and tested in a dust-free environment, so operators need to wear special dust-free clothing and accessories to ensure a clean environment. As an important part of dust-free clothing and accessories, gloves are widely used in clean rooms. They can not only protect products and production areas from pollution, but also protect operators from harmful components in the production process. Among them, nitrile gloves have many advantages such as adhesion, good ductility, no protein, and no allergies, etc., and are widely used. [0003] At present, there are many varieties of nitrile gloves. Nitrile gloves are mainly made by dipping nitrile latex, molding, vulcanization, surface tr...
