BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. First, the manufacturing method of the present invention will be described with reference to the drawings. FIG. 1 shows a simplified flow sheet of the manufacturing method of the present invention. First, in the first step, the washed and washed glove mold is immersed in the coagulant tank 1 in a coagulating liquid composition containing a rubber vulcanizing agent and a rubber coagulating agent. Thereafter, the glove mold is pulled up and dried, and a rubber vulcanizing agent and a rubber coagulant are attached to the glove mold surface. The glove mold is introduced into the latex tank 2 in the next step, and is immersed in the rubber compounded latex. After the glove mold is pulled up and dried, a leaching treatment is performed in the hot water washing tank 3 to extract and remove water-soluble components and a coagulant. The gelled rubber layer formed on the surface of the glove mold to which the rubber vulcanizing agent and the rubber coagulant have adhered is heated and vulcanized by passing through the hot air tank 4 in the next step. The vulcanized rubber layer is inverted and removed from the glove mold in the last step.

In the method for producing a rubber glove according to the present invention, first, as a first step, a glove mold is immersed in a liquid composition for coagulation. After washing with, it is washed with water. Then, while being heated to 40 to 70 ° C, it is immersed in a coagulating liquid composition containing a rubber vulcanizing agent and a rubber coagulant. In the present invention, the glove type has a shape corresponding to the contour of a human hand, for example, from the wrist to the fingertip, from the elbow to the fingertip, and various shapes according to the purpose. And a porcelain mold, an aluminum mold, a plastic mold and the like are preferably used.

In the present invention, it is necessary that the liquid composition for coagulation in which the glove mold is dipped contains a rubber vulcanizing agent together with a rubber coagulant. Any rubber vulcanizing agent can be used as long as it is generally used for vulcanizing rubber, but a vulcanization accelerator having a vulcanizing action may be used. Specific examples include sulfur, zinc oxide, magnesium oxide, dithiocarbamate, and thiuram polysulfide. These rubber vulcanizing agents have a concentration of 0.5 to 10% by weight in the coagulating liquid composition.
May be contained, preferably in the range of 1 to 5% by weight.

As the rubber coagulant, metal salts such as calcium salts and zinc salts are used, and calcium nitrate is particularly preferable. In addition, calcium chloride, cyclohexylamine acetate, zinc chloride and the like can be used. Can be used. In addition, these rubber coagulants
It is used in a form dissolved in a solvent.
Alcohols such as methyl alcohol and ethyl alcohol or a mixture of water and alcohols are used. The concentration of the rubber coagulant in the liquid composition for coagulation is set in the range of 10 to 40% by weight, preferably 15 to 30% by weight.

The liquid composition for coagulation may contain 0.1 to 20% by weight of at least one selected from emulsion type silicone resin, synthetic resin fine powder and inorganic oxide fine powder. As the silicone resin, dimethylpolysiloxane, diethylpolysiloxane, methylphenylsilicone, or the like can be used.As the synthetic resin, a coagulate or agglomerate is not generated even when contacted with the above coagulant, and an acrylic resin, Examples thereof include urethane resins, polyamide resins, olefin resins, formaldehyde resins, vinyl chloride resins, vinylidene chloride resins, starches, and crosslinked products thereof. Also,
As the inorganic oxide, silica, alumina and the like can be used. These fine powders are preferably used as particles having a particle diameter in the range of 1 to 50 μm. After dipping in the liquid composition for coagulation, the glove mold is removed and dried, so that the rubber vulcanizing agent and the rubber coagulant adhere to the surface of the glove mold.

In the next step, the glove mold to which the rubber vulcanizing agent and the rubber coagulant have adhered is immersed in a rubber compounded latex to deposit gelled rubber on the glove mold surface. In the present invention, conventionally known rubber latex can be used as the rubber compounded latex, and for example, synthetic rubber latex such as natural rubber latex and NBR can be preferably used. To these rubber compounded latexes, together with a small amount of a vulcanizing agent, a vulcanization accelerator, an antioxidant, a thickener, a wetting agent, an antifoaming agent, and the like, which are usually added to the rubber latex, may be appropriately added. Good. The concentration of the rubber compounded latex is usually preferably in the range of 30 to 50% by weight. In the present invention, the thickness of the rubber layer is usually 50
It is preferable to set the thickness in the range of -300 µm.

The glove mold immersed in the rubber-containing latex is pulled up and passed through, for example, a hot air bath at 60 ° C. to 100 ° C. for 10 to 90 seconds to form a gelled rubber layer. In order to remove water-soluble substances such as proteins and coagulants therein, extraction (leaching) is performed in warm water at 30 to 90 ° C. for 20 seconds to 10 minutes. Then, it heat-drys at 70-100 degreeC for 30 second-2 minutes.
As a result, an extracted gelled rubber layer is formed on the glove mold. The surface of the gelled rubber layer is preferably subjected to an anti-tackiness treatment, if desired. For example, a fine powder such as starch or talc may be attached, or a silicone resin emulsion may be applied. Thereby, the adhesion of the inner surface of the obtained glove can be prevented. Also,
For example, a polymer emulsion containing organic resin fine particles can be applied to prevent sticking and improve lubricity.

The gelled rubber layer subjected to the extraction treatment is heated and vulcanized in the next step. That is, 90
It is dried by heating at １３０130 ° C. for 10 to 30 minutes to cure and cure the rubber of the gelled rubber layer.

The gelled rubber layer treated as described above is finally inverted and removed from the glove mold. This gives a tack-free rubber glove with improved surface slipperiness.

In another embodiment of the present invention, the glove mold having the gelled rubber layer extracted as described above is immersed in an aqueous dispersion containing a synthetic rubber latex and organic fine particles. This aqueous dispersion has a nonvolatile content of 0.5 to 10% by weight and a viscosity of 1 to 10% by weight.
Those having a range of 300 mPa · s are used. In particular,
In order to obtain a slippery resin layer having excellent detachability, the concentration is suitably in the range of 2 to 5% by weight, and the viscosity is suitably in the range of 3 to 50 mPa · s. By immersing in this aqueous dispersion, a fine particle-containing synthetic rubber latex layer (second layer) having irregularities in which organic fine particles are dispersed in synthetic rubber is formed on the gelled rubber layer (first layer). You. This is 70-1
After heating and drying at 00 ° C. for 30 seconds to 2 minutes, beading (edge cuffing) is performed by a beading device as necessary.

Then, as described above, 90-130 ° C.
For 10 to 30 minutes to cure and cure the first gelled rubber layer and the second fine particle-containing synthetic rubber latex layer. Thereby, a laminate including the vulcanized rubber layer and the lubricating resin layer is formed. The vulcanized laminate is inverted from the glove mold and demolded to obtain the rubber glove of the present invention in which the rubber layer is on the outer surface side and the slippery resin layer is on the inner surface side.

In the present invention, the synthetic rubber latex used in the aqueous dispersion is one which does not generate a coagulated product or a coagulated product even when it comes into contact with the above coagulant, and specifically, a styrene-butadiene system Latex, methyl methacrylate-butadiene-based latex, acrylonitrile-butadiene-based latex, butadiene rubber latex, isoprene rubber latex and the like are used, and these are used alone or in combination of two or more. These synthetic rubber latexes are preferably obtained by post-adding a polymer protective colloid represented by a nonionic surfactant or polyvinyl alcohol to a latex stabilized using an anionic surfactant or the like. However, a commercially available synthetic rubber latex may be mixed with a nonionic surfactant. Further, a synthetic rubber latex having a carboxyl group can also be used. The choice of synthetic rubber latex is not particularly limited, but it is desirable that the unstretched film has an elongation of 300% or more and a tensile strength of 3 Mpa or more.

The organic fine particles used in the aqueous dispersion include acrylic resin, urethane resin, polyamide resin, olefin resin, formaldehyde resin, vinyl chloride resin, vinylidene chloride resin, starch resin and cross-linked thereof. Organic fine powders such as organic substances, and these may be used alone or in combination of two or more. The organic fine particles have an average particle size in the range of 1 to 50 μm, and preferably 2 to 30 μm, in order to obtain good lubricity.
If the average particle size is less than 1 μm, the lubricity due to unevenness is poor, while if it exceeds 50 μm, there is a feeling of roughness and poor feeling in use. Further, the amount of addition is 10 to 100 parts by weight with respect to 100 parts by weight of the nonvolatile content of the synthetic rubber latex,
Preferably it is 30 to 70 parts by weight. If the amount is less than 10 parts by weight, a sticky feeling is felt and lubricity is poor. On the other hand,
If the amount exceeds 100 parts by weight, the elongation of the coating film of the lubricating resin layer is too short to follow the elongation of the rubber glove body, and the adhesiveness becomes insufficient, which is not suitable. The shape of the organic fine particles is not particularly limited, but a spherical shape is preferable in terms of lubricity.

In the present invention, in addition to the synthetic rubber latex and the organic fine particles, the aqueous dispersion contains, in order to improve the adhesion, strength and water resistance of the lubricating resin layer to the rubber glove body, As a curing agent, an aqueous solution or aqueous dispersion of an amino resin, a blocked isocyanate or an epoxy resin can be added. As the amino resin, a water-soluble methylated melamine resin, a methylated urea resin, or the like is used. As the blocked isocyanate, a nonionic aqueous dispersion of an isocyanate compound blocked with a known blocking agent such as phenol, lactam and oxime is used. Also, as epoxy resin,
Water-soluble sorbitol polyglycidyl ether, sorbitan polyglycidyl ether, polyglycerol polyglycidyl ether, diglycerol polyglycidyl ether, glycerol polyglycidyl ether, polyethylene glycol diglycidyl ether and the like are used.
The amount of these hardeners to be added is in the range of 1 to 50 parts by weight, preferably 5 to 30 parts by weight, per 100 parts by weight of the nonvolatile content of the synthetic rubber latex. In order to accelerate the curing, a known catalyst may be added as long as the stability of the aqueous dispersion is not impaired.

The above aqueous dispersion may contain a thickener, a wetting agent, an antifoaming agent,
Conditioners, antioxidants, ultraviolet absorbers, preservatives, antibacterials,
An antistatic agent, a coloring agent, and the like can be appropriately added. Further, a silicone emulsion may be added for the purpose of improving lubricity. As the thickener to be used, methyl cellulose, polyvinyl alcohol, ammonium acrylate and the like are preferable, and as the wetting agent and the defoaming agent, a nonionic fluorine-based surfactant, a silicone emulsion and the like are preferable.

In the present invention, a smooth resin layer having a uniform appearance is formed by using the above aqueous dispersion. Furthermore, since this slippery resin layer is formed using a synthetic rubber latex, it has good adhesion to the first rubber layer and can follow the elongation of the glove body. In addition, since organic fine particles are blended, unevenness is formed on the surface and the surface has lubricity, so that the organic fine particles do not fall off. Therefore, a rubber glove which is hygienic and has excellent detachability is obtained.

According to the manufacturing method of the present invention, since it has the above-described structure, it is possible to form the non-sticky glove outer surface in the on-line process until the rubber glove formed from the glove mold is released. . Therefore, there is no need for a treatment step for imparting non-tackiness such as a chlorination treatment after demolding, so that there is an advantage that the production process is significantly simplified. According to the present invention, since a high-concentration vulcanizing agent is attached to the surface of the glove mold, the surface of the rubber layer formed thereon, that is, the surface that becomes the outer surface of the glove,
Vulcanization results in a high degree of crosslinking and loss of tack.
Therefore, the formed rubber glove has excellent gripping properties when dry or wet, and also has excellent blocking resistance, so that the gloves do not adhere to each other even when they are stacked. Further, since the outer surface of the glove is not subjected to the chlorination treatment, there is no problem such as deterioration of durability due to discoloration or deterioration of physical properties of rubber and occurrence of environmental problems.
