Abstract

PURPOSE:To provide the title grove stable in physical properties with its inner surface sustainable in non-tackiness. CONSTITUTION:The objective grove can be obtained by providing a film 2 of e.g. urethane resin containing a desired organic lubricant on the inner surface of the grove body 1 produced by forming a desired polyvinyl chloride resin solution into a film.

Description

[Detailed description of the invention]

0001

FIELD OF THE INVENTION This invention relates to non-stick vinyl chloride gloves.

0002

[Prior Art] Conventionally, this type of vinyl chloride gloves have been coated with powder or vinyl chloride blend resin (
JP-A-61-249716, JP-A-61-249
No. 717) and has non-adhesive properties.

0003

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, the powder coating peels off during use, and the vinyl chloride blend resin coating changes the physical properties and becomes rough on the hands. It had a defect.

[0004] The present invention has been devised in view of the problems of the prior art, and its purpose is to provide vinyl chloride gloves that do not impair their non-adhesive properties and do not change their physical properties. That's true.

[0005]

[Means for Solving the Problems] The technical means of the present invention to achieve the above object is to provide a film containing an organic lubricant on the inner surface of the glove body.

[0006]

[Function] By means of the technical means described above, the film containing the organic lubricant has excellent adhesion to the inner surface of the vinyl chloride glove body, and provides lubricity to the surface that comes into contact with the hand.

[0007]

[Example] An embodiment of the present invention will be described below with reference to the drawings. The glove of the present invention is manufactured by using a manufacturing mold made of ceramic or metal, etc., which has a form and structure well known in this technical field. After adjusting the manufacturing mold to a predetermined temperature, the mold is dipped once or twice in a vinyl chloride resin solution to deposit the vinyl chloride paste that will become the glove body, then pulled out, semi-cured, and cooled. Then, one or two layers, or several layers if necessary, of the glove body 1 are formed on the mold surface, and then the glove body 1 is again dipped in the surface treatment agent.

[0008] Vinyl chloride resin solution is a well-known vinyl chloride paste made by blending various commonly used additives such as plasticizers, stabilizers, gelling agents, and pigments with vinyl chloride paste resin. Viscosity 4000-10,0
A vinyl chloride paste of 00 cps is attached to a glove manufacturing mold, semi-cured, and cooled to form a film consisting of one or two layers that will become the thin film-like glove body 1, and a surface treatment agent is applied to the surface of this film. A applied film 2 is formed.

The surface treatment agent is an emulsion type containing a desired organic lubricant in urethane resin, acrylic resin, vinyl chloride resin, etc. and has a viscosity of 10 to 200 cps. The glove manufacturing mold having the film layer is immersed again to perform surface treatment, and then pulled up, pre-dried, cured, and cooled in order to form the film 2.

Therefore, by inverting and releasing the film 2 on the surface of the main body 1 provided on the production mold as described above, a glove with the film 2 provided on the inner surface of the glove main body 1 is formed. .

Next, a specific embodiment will be described. A glove manufacturing mold whose mold temperature is adjusted to 50°C is immersed in a vinyl chloride paste having the following formulation (a) at a liquid temperature of 35°C, and after being pulled out, the mold is heated to 170°C. Semi-cure for 4 minutes and cool to mold temperature.

[0013]Although the above formulation example includes a vinyl chloride dry blend resin, it is optional, and can provide unevenness on the surface.

[0014] To explain one method for producing the above-mentioned PVC dry blend resin, for example, PVC straight resin
100 plasticizer (DOP)
30 into a desired mixer, stirred at high speed until the temperature reached 70-80°C, then stirred at low speed, and cooled with cold water to room temperature in a jacket to complete.

Next, it was immersed in an emulsion type surface treatment agent (liquid temperature 25°C) of the following formulation (b) at 60cm/min and pulled up at 30cm/min, then pre-dried for 2 minutes at 60-140°C, and then pre-dried at 220°C for 8 minutes. After curing and cooling to a mold temperature of 70° C., the mold was inverted and released to obtain vinyl chloride gloves. These gloves are non-adhesive, have a soft and supple texture (low modulus and high elongation) with no deterioration in physical properties, have good oil resistance, have no foreign body sensation, are comfortable to use, and are easy to release from the mold and put on and take off the hands. It was easy.

[0016]

Examples of the above organic lubricants are shown in Table 1, and any or all of them may be added.

[Table 1] In addition, Table 2 shows the physical properties and lubricity of the products of the present invention, products without surface treatment, and products without organic lubricant.

[Table 2]

[0018] The physical properties are based on JIS S2045, and for slipperiness, place vinyl on a stand whose angle can be freely changed (treated side up), gently place 2g of funda, and adjust the angle of the stand. I changed the angle and compared the angle at which the fundo begins to slide.

[0019]

Effects of the Invention The present invention provides a film containing an organic lubricant on the inner surface of the vinyl chloride glove body, so the film has excellent adhesion to the vinyl chloride glove body and does not peel off. It also provides lubricity on the surface that comes in contact with the hand,
It maintains its non-adhesive properties for a long period of time, and there is no change in physical properties, making it very useful and easy to use.
