Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an NBR glove, and more particularly, when used as a household or work glove, the surface is not slippery, although easy to wear,
The present invention relates to a NBR glove that is easy to use.

[0002]

2. Description of the Related Art At present, so-called non-support type gloves based on polymers or rubber are provided as household or working gloves. Vinyl chloride is often used as the base material of this non-support type glove, but when working with petroleum, the plasticizer will elute from the vinyl chloride glove, There is a problem that it cannot withstand long-term use because it hardens. In addition, weakness in terms of mechanical strength has been a problem such that holes are likely to be formed when pierced by a pointed object and further easily worn.

Nitrile-butadiene rubber (N
Although gloves made of BR) are provided, the NBR gloves have a stickiness peculiar to rubber, which has been a serious problem during use and production.

That is, due to the stickiness of the NBR, there are problems that it is intimately attached to the hand when it is worn, and that it is inconvenient to attach and detach. And as a method of solving such a problem at the time of use, chlorine treatment of the entire NBR glove is performed, and this method improves slippage on the inner surface, but at the same time makes the outer surface too slippery, It had the drawback of discoloring.

In order to prevent the above-mentioned drawbacks, some kind of pulverized body is used as a release aid after film formation, but in the glove thus obtained, powder remains on the back surface. Therefore, it has a drawback that it cannot be used in electronic parts and precision industries.

The non-support type glove is a product in which the hand type is dipped in the polymer latex constituting the glove, and the attached polymer latex is heated to gel, film-form, and then inverted. Therefore, NB as a polymer latex
When R latex is used, the coatings stick to each other at the time of release after film formation, which is a problem in production. Further, when the above-mentioned chlorine treatment is performed, chlorine gas, which is extremely toxic, is used, so there is a problem that further careful handling is required in terms of safety and equipment.

[0007]

Therefore, the stickiness peculiar to NBR gloves, which is a problem during use and manufacturing, is
There was a demand for the development of a method to prevent chlorination and the use of release powder.

[0008]

In view of the above situation, the inventors of the present invention have made earnest studies on prevention of stickiness of NBR gloves, and as a result, by providing an acrylic resin layer only on the inner surface of the gloves, The present invention has been completed by finding that the drawbacks of NBR during use can be eliminated.

That is, the present invention provides an NBR glove characterized in that an acrylic resin layer is provided on a part or all of the inner surface of a glove base made of NBR resin, and a method for producing the same.

The NBR glove of the present invention is N
It is manufactured by forming a substrate with BR latex and forming it, and then forming an acrylic resin layer with an acrylic resin paste.

Specifically, first, the hand mold is immersed in an NBR latex compound consisting of NBR latex, a vulcanizing agent, a stabilizer, an activator, etc., and this is pulled up and heated to gel the NBR on the surface of the hand mold. Turn into. The immersion time in the NBR latex compound of hand type is about 10 to 120 seconds, and the heating after the immersion is at a temperature of about 50 to 150 ° C.
It may be performed for about 30 to 120 minutes.

Next, this is dipped in an acrylic resin emulsion consisting of acrylic resin, organic or inorganic fine powder, dispersant, etc., pulled up and heated to form a film. The acrylic resin used here is one containing an acrylic resin as at least a part of the constituent components, and besides the original acrylic resin, a mixture of acrylic resin and urethane resin,
It also includes a mixture of acrylic and styrene resins. The immersion time of this acrylic resin emulsion is 0.5 to 1.5.
It may be about minutes, and the drying after pulling is 80 to 15
It may be performed at a temperature of about 0 ° C. for about 20 to 60 minutes.

It should be noted that inorganic fine particles such as calcium carbonate and silica, and organic fine particles such as vinyl chloride resin can be added to the acrylic resin emulsion in order to provide a proper sliding effect. The amount of the fine particles to be blended is generally about 30 to 150% by weight with respect to the emulsion, and if the amount is too large, the film strength of the acrylic resin layer may be significantly reduced.

The acrylic resin paste also contains
Antibacterial and antifungal agents can be added to suppress the growth of mold and bacteria in gloves. Examples of the antibacterial agent and antifungal agent include Neocintol (Shinto Paint Co., Ltd.) and Preventol BCM (Bayer Co., Ltd.).

Finally, the NBR glove of the present invention is obtained by reversing the film-formed gloves from the hand mold.

The present invention utilizes the property that the NBR and the acrylic resin are well compatible and form an integrated film. The NBR glove of the present invention obtained as described above has no influence on the outer NBR portion,
Since only the inner surface is provided with the acrylic resin layer for proper slipperiness, there is no inconvenience during manufacturing and use due to stickiness as in conventional NBR gloves. In addition, since it is possible to mix fine particles that have a sliding effect, an antibacterial agent and an antifungal agent in the acrylic resin layer, it is possible to provide an appropriate anti-stickiness effect on the inner side and prevent generation of odors and the like. It is possible to make gloves that are comfortable to use.

[0016]

INDUSTRIAL APPLICABILITY The NBR glove of the present invention does not have the drawbacks of the conventional gloves of the same kind, that is, the fact that it is sticky and it is difficult to put hands inside, and the chlorine treatment makes the surface slippery. Both the outer surface and the outer surface can be appropriately used. Since NBR does not have the drawback of being weak in oil resistance and mechanical strength like vinyl chloride gloves, the NBR gloves of the present invention can be widely used as household and industrial gloves instead of vinyl chloride gloves. I have.

EXAMPLES Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.

Example 1 A palm portion of a ceramic hand was immersed in NBR latex having the composition shown in Table 1 for 2 minutes and pulled up. Next, this hand mold was heat-treated in a heating kiln (110 ° C.) for 5 minutes to gel the sol on the surface of the hand mold to form an NBR substrate coating.

The hand mold on which this base film was formed was dipped in an acrylic resin paste having the composition shown in Table 2 for 60 seconds to adhere the acrylic resin sol. Next, this hand mold was heat-treated in a heating kiln (110 ° C.) for about 70 minutes to form a film on the whole, and then the hand mold was reversed and released to obtain an NBR glove (invention product 1).

[0020]

[0021]

Example 2 NBR gloves (invention product 2) were obtained in the same manner as in Example 1 except that the acrylic resin emulsion having the composition shown in Table 3 was used.

[0023]

Trial Example 1 About the NBR gloves obtained in Examples 1 and 2, 16
The panel of the name was used to examine the slipperiness during wearing and use. As a control, a glove formed with only NBR (Comparative product 1) and a glove obtained by chlorinating Comparative product 1 (Comparative product 2) were used. Table 4 shows the results.
