Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Technical Field) The present invention relates to soft vinyl chloride resin gloves used for medical, household, etc. purposes, and in particular, the gloves are relatively easy to put on and take off. This invention relates to soft vinyl chloride resin gloves that can be used for various purposes.

(Prior art) Conventionally, direct contact between the magic trick and the object to be touched is avoided, prevention of adhesion of the object to be touched by the magic trick, and contamination due to transfer of bacteria etc. from the magic trick to the object to be touched or from the object to be touched to the magic trick. Gloves made of flexible synthetic resins and natural and synthetic rubber are commonly used for purposes such as preventing injuries. Among these, soft vinyl chloride resin gloves are particularly useful because they are easily manufactured by dipping vinyl chloride paste, have constant quality, and are inexpensive.

However, such soft vinyl chloride resin gloves have problems such as blocking between their inner surfaces and a sticky feeling on the inner surface, making it extremely difficult to insert and remove the gloves from magic tricks. It involved sex. In order to make it easier to put on and take off such gloves, treatments such as scattering fine particles on the inner surface of the glove or embossing the inner surface have conventionally been used.
None of them gave satisfactory results.

In other words, in the method of spraying fine particulate powder such as talc or mica on the inner surface of the glove, the fine particulate powder will come off the inner surface after long-term use, making it virtually useless, and it is difficult to use magic tricks. When wearing these gloves, there are problems such as the fine powder adhering to magic tricks, making it necessary to wash the hands afterward.On the other hand, in order to embossing the inner surface, it is usually necessary to mold the gloves. This is sometimes done by copying the embossing on the mold surface, but the embossing on the inner surface of the glove formed by this method is insufficient, and the effect of making it easier to put on and take off the glove is not substantial. I couldn't hope for it.

(Problems to be Solved by the Invention) Therefore, the present invention aims to solve the difficulty in putting on and taking off the glove made of soft vinyl chloride resin.

That is, an object of the present invention is to provide a novel soft vinyl chloride resin glove. The present invention also provides a glove made of soft vinyl chloride resin, in which: - Mutual blocking of the inner surfaces and stickiness of the inner surfaces are substantially eliminated;
It is an object of the present invention to provide a soft vinyl chloride resin glove that is easy to put on and take off.

Structure of the Invention (Means for Solving the Problems) As a result of intensive research to achieve the above-mentioned objects, the inventor of the present invention has developed a method by blending a cross-linked vinyl chloride resin into a vinyl chloride paste and applying a dipping process to the vinyl chloride paste. It has been found that when the glove is molded, fine irregularities are formed on the surface of the glove by the crosslinked vinyl chloride resin particles, and these irregularities solve the problems of blocking and sticky feeling.

The present invention is characterized in that a soft vinyl chloride resin glove has minute irregularities formed by particles of crosslinked vinyl chloride resin blended in a soft vinyl chloride resin composition on at least its inner surface. These are soft vinyl chloride resin gloves.

(Specific explanation of configuration) Hereinafter, the present invention will be explained in more detail based on the drawings.

The soft vinyl chloride resin glove 1 of the present invention has minute irregularities at least on its inner surface 2, as shown in FIG. Therefore, these minute irregularities are formed by the particles 3 of the crosslinked vinyl chloride resin contained in the soft vinyl chloride resin composition constituting the soft vinyl chloride resin glove 1, which are present on the surface of the glove 1. It is something that In addition, the average height from the bottom of the concave part to the top of the convex part of this minute unevenness is 5 to 150 μm, preferably 10 to 10 μm.

It is mm2.

The soft vinyl chloride resin composition constituting the soft vinyl chloride resin glove 1 of the present invention contains crosslinked vinyl chloride resin as described above, and preferably contains 5 to 1/2 of the total amount of resin components in the soft vinyl chloride resin composition. It contains % DO by weight, preferably Ω o -go % by weight crosslinked vinyl chloride resin.

As is well known, this crosslinked vinyl chloride resin is composed of a vinyl chloride monomer or a vinyl chloride comonomer and a comonomer copolymerizable with it, and a polyfunctional compound having two ethylenic double bonds in the molecule. It is substantially insoluble in Examples of comonomers copolymerizable with vinyl chloride comonomers include vinylidene chloride, ethylene, propylene, vinyl acetate,

Examples of polyfunctional compounds include diallyl compounds such as diallyl maleate and diallyl phthalate, diacrylate compounds such as ethylene glycol diacrylate, polyethylene glycol diacrylate, and bisphenol A-modified diacrylate, ethylene glycol dimethacrylate, and polyethylene glycol dimethacrylate. dimethacrylate compound and terminal hydroxyl group 1,
Examples include 1,2-polybutadiene compounds such as 2-polybutadiene and epoxidized 1,2-polybutadiene.

In addition, other components of the soft vinyl chloride resin composition include uncrosslinked xenyl chloride resin and a plasticizer. Agents, etc. are added.

Examples of uncrosslinked vinyl chloride resins include, in addition to vinyl chloride homopolymers, vinylidene chloride homopolymers and vinyl chloride-based materials such as vinylidene chloride, ethylene, propylene, vinyl acetate, vinyl fluoride,
There are copolymers with styrene, vinyltoluene, vinylpyridine, alkyl acrylate, alkyl methacrylate, etc., and their average degree of polymerization is 500-3000. Preferably it is 800-2500.

In addition, as a plasticizer, dibutyl phthalate (DBP>

Examples include citric acid esters such as tributylacetyl citrate, trioctyl acetyl citrate, and dobutyl citrate, and butylphthalyl glycolate (BPBG), with di-2-ethylhexyl phthalate being preferred.

These plasticizers are blended in an amount of 20 to 150 parts by weight, preferably 40 to 120 parts by weight, per 100 parts by weight of the resin component of the soft vinyl chloride resin composition.

The soft vinyl chloride resin glove of the present invention having the above configuration has the same features as conventional soft vinyl chloride resin gloves.
It can be easily manufactured by dipping a vinyl chloride paste.

That is, first, a plastisol is prepared by mixing and dispersing a crosslinked vinyl chloride resin as described above and an uncrosslinked vinyl chloride resin in a plasticizer as described above at room temperature. The particles of crosslinked vinyl chloride resin used at this time have an average particle size of 10
~150 μm, preferably 30 to 120 μm, while the average particle size of uncrosslinked vinyl chloride resin particles is 4.
The thickness is 0 to 200 μm, preferably 80 to 150 μm.

That is, if the particle size of the crosslinked vinyl chloride resin is less than 10 μm, there is a risk that the uneven shape on the inner surface of the molded product will not be sufficiently formed, and if it exceeds 150 μm, there is a risk that it will not be uniformly dispersed in plastisol. This is because there is a risk of causing poor appearance such as fish eyes in the molded product, and if the particle size of -5 uncrosslinked vinyl chloride resin is less than 40 μm, there is a risk of swelling with the plasticizer at room temperature. Moreover, if it exceeds 200 μm, there is a risk that it will not be uniformly dispersed in the plastisol and that it will not be completely melted during high-temperature melting.

Place the plastisol prepared in this way and hold at 20°C.
A flat mold 5 is immersed as shown in FIG. 2b in a vinyl chloride paste bath 4 as shown in FIG. After uniformly applying the plastisol to the surface of the flat mold 5, as shown in FIG. 2C, the plastisol is pulled up at a constant pulling speed,
After cutting the sauce, as shown in FIG. 2d, using a heating device 6 such as an infrared lamp or hot air dryer,
maximum of 170-230°C, preferably 190-21
The uncrosslinked vinyl chloride resin component is heated to 0°C to swell the plasticizer, gelatinize, and melt to obtain a product. At this time, the crosslinked vinyl chloride resin particles remain in the product as molten dust particles and form fine irregularities on the surface of the product. Incidentally, as shown in FIG. 3, the surface irregularities formed at this time are more fully formed on the free surface side 8 than on the mold side 7, so remove the vinyl chloride resin glove 1 from the handprint 5. After that, it is preferable to arrange the binding so that the free surface side 8 becomes the inner surface of the manual binding.

The method for manufacturing the vinyl chloride resin glove 1 of the present invention is not limited to the above method, and plastigel, organosol, or organogel may be used instead of plastisol, or other methods may be used instead of rough paste processing. It is also possible to use molding methods.

(Example) Hereinafter, the present invention will be explained in more detail based on examples.

Example 1 Vinyl chloride resin with an average particle size of 100 μm (P=1700>
A plastisol was prepared by mixing and dispersing 100 parts by weight of particles and 50 parts by weight of crosslinked vinyl chloride resin particles having an average particle size of 50 μm in 100 parts by weight of DOP. Using this plastisol, soft vinyl chloride resin gloves were obtained as shown in Figures 2a to 2d. At this time, the temperature of vinyl chloride paste bath 4 was 30°C, the immersion time was 8 seconds, and the pulling speed was 3.
0Cm/min, heating temperature increase condition 10℃/min, maximum heating temperature 2
The conditions were 10°C.

When we investigated the microstructure of the obtained soft vinyl chloride resin gloves, we found that minute irregularities were formed on the inner surface (free surface side), and the height from the bottom of the concave part to the top of the convex part of these irregularities was The average is 35 μm, and the number of protrusions per unit area is 7.
It was 0 pieces/mm2.

When this glove was actually used, there was no blocking between the inner surfaces and no sticky feeling on the inner surface, and the gloves could be put on and taken off smoothly even after long-term use.

Effects of the Invention As described above, the present invention provides soft vinyl chloride resin gloves with minute irregularities formed by particles of crosslinked vinyl chloride resin blended in a soft vinyl chloride resin composition on at least the inner surface thereof. Because of this, there is no blocking between the inner surfaces and no sticky feeling on the inner surfaces, allowing for smooth attachment and detachment even after long-term use, and a good wearing feeling. Like the soft vinyl chloride resin gloves, these gloves can be manufactured by paste processing, and are extremely excellent for medical, household, and other uses.
