Problems solved by technology

However, the introduction of collagen, protein, etc. will increase the threat of allergic reactions, which violates the original intention of using nitrile gloves. The reason why people widely use nitrile gloves is that they do not contain latex protein and will not cause allergic reactions.
Moreover, the use of natural degradable materials such as cellulose and starch is carefully blended, and the chemical corrosion resistance and physical properties of the gloves drop sharply, which does not meet the performance level of ordinary non-degradable gloves. Low
Chinese patent CN2018106797858 discloses degradable gloves and its preparation method, which are not easy to tear, and have excellent degradable properties, suitable for use in various environments, and the scope of application in various environments is greatly limited
At present, there are few corresponding products and technologies for degradable nitrile rubber gloves in the market

Abstract

The invention belongs to the field of high polymer materials. The invention relates to gloves, in particular to degradable nitrile rubber gloves forming preparation method. The invention discloses a forming preparation method of degradable nitrile rubber gloves. The preparation method is simple, convenient and easy to implement, and the prepared gloves have the characteristics of acid and alkali resistance, oil stain resistance, permeation resistance, bacteria resistance, no latex allergy and convenience in use, are lighter, thinner and softer in touch feeling, excellent in elasticity, excellent in physical property and chemical property, free of any natural latex component, free of allergy risk, good in degradability and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a molding preparation method of degradable nitrile rubber gloves. Background technique [0002] Nitrile gloves refer to gloves made or painted, with oil-proof effect, mainly used in factories, oil fields, repair shops, etc. Nitrile gloves do not contain latex protein, so they will not cause allergic reactions. At the same time, they are antistatic, resistant Aging and oil resistance, the shape of the glove is designed according to the shape of the human hand, with great sensitivity, excellent tensile properties and puncture resistance, high tensile strength and excellent wear resistance. However, nitrile latex has the characteristics of low wet gel strength, large shrinkage, poor film-forming performance, and low vulcanized film strength, so it is difficult to make dipped products. Especially for the production of thin gloves, it has been a difficult problem for glove ...
