BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to work gloves made of NR (natural rubber).

[0002]

2. Description of the Related Art Conventional NR work gloves are constructed by providing an NR layer on the outer surface of a glove base made of knitted fabric.

[0003]

However, since the conventional NR work gloves have poor oil resistance, they are not suitable for work with oil such as kerosene and gasoline. Therefore, there is a work glove made of NBR (acrylonitrile butadiene rubber) that has excellent oil resistance, but since NBR is expensive, it is a very expensive work glove that is a consumable item. .

Then, as a result of earnest studies, the inventor of the present application paid attention to providing NBR as a film on the outer surface of the glove body made of the NR layer, and succeeded in bonding those having different polarities.

The present invention has been made in view of the above problems of the prior art, and its purpose is to provide an NBR coating on the outer surface of the glove body composed of the NR layer. It is to provide gloves.

[0006]

In order to achieve the above object, the technical means of the present invention is to provide a glove body by forming an NR layer on the outer surface of a glove base body made of knitted fabric. A modified urethane layer or modified NR on the outer surface of the glove body
That is, the NBR film is provided via the layers.

Further, the above NBR film is formed on the surface of the NBR film.
The rubber powder may be projected to form a non-slip coating.

[0008]

By the above technical means, the modified urethane layer or the modified NR layer functions as a binder between the NR layer and the NBR layer on the surface of the glove body to promote the adhesion between them. That is,
Since the modified urethane layer (polarity 8.2 to 10) or the modified NR layer (polarity 8 to 9) is an intermediate polarity between the polarities (8) (9 to 10) of the NR layer and the NBR layer, respectively. And the like.

If NBR rubber powder is projected on the surface of the NBR layer, the NBR rubber powder will prevent slippage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of working gloves of the present invention will be described below with reference to the drawings.

A working glove A of the present invention comprises a glove body a formed by providing an NR (natural rubber) layer 2 on an outer surface 1a of a glove base body 1, and a modified urethane layer on an outer surface a'of the glove body a. 3 and an NBR (acrylonitrile butadiene rubber) layer 4 provided therebetween. The glove substrate 1 is formed into a desired glove shape by knitting cloth such as knitted fabric and ****. The shape of the glove base 1 is arbitrary and is not limited in any way.

The NR layer 2 has a polarity of 8 and is made of the following composition, for example, and is provided on the entire outer surface 1a of the glove substrate 1 to a desired thickness. [Blending] NR latex (Dry) 100 parts by weight S 1〃 Zno 1〃 Dithiocarbamate vulcanization accelerator 0.8〃 Antiaging agent 1〃 Stabilizer Appropriate amount of thickener〃 Pigment / antibacterial agent〃, concentration 50 ~ 55%, viscosity 300 ~ 600CP
Adjusted to S.

The modified urethane layer 3 has a polarity of 8.2 to 10 and is an intermediate polarity between the NR layer 2 and the NBR layer 4 described later,
It is used as a binder for adhering the NR layer 2 and the NBR layer 4, and is provided in a desired thickness on the outer surface 2a of the NR layer 2. The modified urethane layer 3 is the NBR layer 4
In the case where the NBR layer 4 is provided only on the palm surface 5 and the finger pad surface 6 as in this embodiment, only that portion is required. When the NBR layer 4 is provided on the entire outer surface of the glove, it may be provided appropriately on the entire surface. An example of the formulation is shown below. [Blending] Polybutadiene-based urethane emulsion 100 parts by weight Water 300 〃 Epoxy crosslinking agent 4 〃, adjusted to a concentration of 1 to 10%.

Even when the modified NR layer 3 (polarity 8 to 9) is used in place of the modified urethane layer 3, the NR layers 2 and N are similarly formed.
There is a binder effect with the BR layer 4, and for example, NR-MMA graft copolymer emulsion adjusted to a concentration of 1 to 10%, specifically Retex NB417 (manufactured by Retex Corp.) is used.

The NBR layer 4 has a polarity of 9 to 10 and is provided on the surface 3a of the NR layer 2 through the modified urethane layer 3 provided on the surface 2a to a desired thickness. In this embodiment, the NBR layer 4 is formed. Of rubber powder 4a ...
When provided on the palm surface 5, the finger pad surface 6, etc., the rubber powder 4a.
A large number of protrusions form the surface of the NBR layer 4 in a concavo-convex shape to provide a non-slip effect. Hereinafter, an example of the composition will be shown, but the invention is not limited thereto. [Blending] NBR-MMA graft copolymer 65 parts by weight Water 20 〃 NBR rubber powder (60 mesh pass) 15 〃 Stabilizer A suitable amount, adjusted to a concentration of 30% and a viscosity of 100 CPS.

That is, the modified urethane layer 3 (polarity 8.2-1)
0) or the modified NR layer 3 (polarity 8 to 9) is the above NR.
Polarity (8), (9-10) of layer 2 and NBR layer 4, respectively
Since they are of intermediate polarity, they are bonded to each other through the modified urethane layer 3 and the like. {NR (8) <NR-MMA (8-9), Polyurethane urethane (8.2-10) <NBR-MMA (9-10)}

An example of the manufacturing process is as follows: (1) Type (aluminum or ceramic) 50 ° C. → (2) Glove substrate (raw hand) cover → (3) Coagulant immersion (6% calcium nitrate methanol solution) → (4) Dry (normal temperature × 2min) → (5) NR
Immersion (600CPS) → (6) Drying (50 ℃ × 8min) →
(7) Modified emulsion (urethane or modified NR) immersion (20 CPS) → (8) Drying (70 ° C × 5 min) → (9)
NBR non-slip dipping (100 CPS) → (10) Dry vulcanization (120 ° C × 1H) → (11) Peeling → (12) Water extraction (60 ° C ×
4H) → (13) Drying (100 ° C. × 1H). The above manufacturing process is merely an example, and the manufacturing process is not limited thereto.

The NR work gloves of this embodiment are compared with the conventional NR work gloves in terms of physical properties, and are summarized in Table 1.

[0019]

[Table 1] * 1 ... JIS-S-2042 * 2 ... Single-sided immersion 20 ° C x 48H

Therefore, the strength and flexibility are not changed, the oil resistance is improved, and the adhesive strength and wear resistance are also good.

[0021]

According to the present invention, the glove body is formed by providing the NR layer on the outer surface of the glove base body made of the knitted fabric as described above, and the modified urethane layer or the modified NR layer is formed on the outer surface of the glove body. In order to provide the NBR film via the NR and NBR, which have greatly different polarities, since modified urethane or the like having an intermediate polarity is used as a binder, a new NBR film is provided on the outer surface of the glove body composed of the NR layer. N
R work gloves can be provided. Therefore, compared with the conventional NR work gloves, oil resistance can be improved while maintaining strength and flexibility. It also has the effect of being extremely cheap (1/3) compared to NBR work gloves that have excellent oil resistance.

When a large number of NBR rubber powders are projected on the surface of the NBR layer to make the surface uneven, the rubber powders have a non-slip effect and are very easy to use together with the above effects.
