Problems solved by technology

However, gloves made of polyethylene are difficult to adapt to the hand, so workability is poor, gloves made of polyvinyl alcohol lack water resistance, and gloves made of butyl rubber are complicated in the manufacturing process and do not have sufficient resistance to non-polar solvents.

Embodiment

[0063] Hereinafter, examples related to the present invention will be described, but the present invention is not intended to be limited to the contents shown in the examples.

[0064] [Example and Comparative Example]

[0065] A mixed liquid containing the components shown in Table 1 was prepared using acrylonitrile-butadiene latex (“KNL870” manufactured by Kumho Corporation). An impregnating liquid A for inner layer formation was prepared by aging the mixed liquid for two days.

[0066] [Table 1]

[0067]

[0068] *Abbreviations in the table are as described below.

[0069] NBR: Acrylonitrile Butadiene Rubber

[0070] BZ: Zinc dibutyldithiocarbamate

[0071] On the other hand, using acrylonitrile-butadiene latex "manufactured by KUMHO: KNL870", chloroprene latex "Neoprene 671A", and chloroprene latex "Neoprene 572", prepared A liquid mixture of the components shown in Tables 2 to 4. Impregnation solution B for outer layer formation was prepared by aging the mixed so...

Abstract

The present invention provides a rubber glove having a multilayer structure, which has high adhesion between layers, excellent resistance to ketones, and excellent dexterity. The rubber glove of the present invention includes an inner layer composed of a crosslinked product of a rubber composition (1) containing acrylonitrile-butadiene rubber; and an outer layer composed of a crosslinked product of a rubber composition (2) containing acrylonitrile-butadiene rubber and chloroprene rubber, wherein the inner layer and the outer layer are adjacent to each other, and two or more types of chloroprene rubber having different crystallization rates are used as the chloroprene rubber.

Description

technical field [0001] The invention relates to a rubber glove. Background technique [0002] Rubber gloves made of a rubber film are widely used in various fields such as general household, industrial production, research, medical treatment, and sports because of their ease of use and low price. Among them, rubber gloves for industrial use are required to have excellent chemical resistance in order to protect hands from chemicals. [0003] A wide range of polar chemicals are used in the field where rubber gloves for industrial use are used. As rubber gloves resistant to non-polar solvents such as hexane and heptane, gloves made of acrylonitrile-butadiene rubber are generally used. However, gloves made of acrylonitrile-butadiene rubber do not have sufficient resistance to polar solvents such as acetone and alcohol. On the other hand, gloves made of polyethylene, polyvinyl alcohol, and butyl rubber are being developed as rubber gloves having excellent resistance to polar s...
