Description

The present invention relates to a method for manufacturing a thermoplastic resin glove, and more particularly to a method for manufacturing a thermoplastic resin glove that uses simple equipment and is environmentally friendly, and a thermoplastic resin glove.

Conventionally, gloves made of thermoplastic resin such as polyvinyl chloride or polyurethane have been used at work sites where chemicals such as organic solvents and detergents are handled to protect the skin of the hands from the chemicals. These gloves are generally manufactured by dip molding.

In the dip molding method, a thermoplastic resin liquid containing additives such as plasticizers is prepared as an immersion liquid, a mold corresponding to the three-dimensional shape of the glove is prepared, and the mold is kept constant in the immersion liquid. In this method, gloves are manufactured by immersing the mold for a long period of time and then pulling it up so that the dipping liquid adheres to the surface of the mold.

The immersion liquid adhering to the mold is heated together with the lifted mold to form a film, and the glove is manufactured by removing the mold.

In order to manufacture thermoplastic resin gloves using the dip molding method, the thermoplastic resin must be made into a liquid state by dissolving it in an organic solvent, or emulsifying or dispersing it in water or a plasticizer. Conversely, thermoplastic resins that cannot be liquefied by melting, emulsifying, or dispersing cannot be used to manufacture gloves by dip molding.

Currently, polyvinyl chloride gloves are often used for cleaning work that uses detergents, acids, and alkalis, but most of the polyvinyl chloride gloves contain polyvinyl chloride with a large amount of plasticizer, as in Patent Document 1. After dispersing the liquid sol into a liquid sol, it is manufactured using a dip molding method. Although the plasticizer used is not harmful to the human body, there are problems in that waste liquid is produced during compounding and equipment cleaning, and the entire factory is contaminated with plasticizer.

In recent years, polyurethane gloves, which have been attracting attention because they do not get stuffy even when worn for long periods of time and have excellent chemical resistance, are also manufactured by dip molding. For example, Patent Document 2 discloses a method for manufacturing breathable polyurethane gloves, which is characterized by immersing a glove mold in a solution of polyurethane in dimethylformamide and adding a low boiling point solvent, and then pulling it up and drying it. However, this method uses dimethylformamide and organic solvents that are harmful to the human body, creating a poor working environment and requiring exhaust and wastewater facilities.

As a method to solve these problems, Patent Document 3 describes a process of preparing an immersion liquid containing an aqueous emulsion of polyurethane with a surface tension of 39 N/m or more and 45 N/m or less, and a step of preparing a ceramic hand that corresponds to the three-dimensional shape of the glove. Disclosed is a method for manufacturing a non-support type glove, which includes the steps of: immersing a mold in the immersion liquid and then pulling it up to apply the immersion liquid to the hand mold; and drying and solidifying the applied immersion liquid. There is. Although these methods do not use organic solvents that are harmful to the human body, the equipment is still large and the problem of waste fluid generation remains unsolved. In addition, since a coagulant is required, a step is required to attach the coagulant to the mold before immersing the mold in the immersion liquid, which complicates the process and also causes the emulsifier derived from the water dispersant to be added to the rubber film. This has caused a problem in that the water resistance strength tends to be low because of the residual content.

Furthermore, chemical resistance, which is one of the important properties of work gloves, can be improved by selecting a thermoplastic resin suitable for the chemicals handled at work sites and by increasing the thickness of the glove film. . However, as mentioned above, in the conventional dip molding method, the raw material is limited to thermoplastic resins that can be liquefied, and there are limits to the improvement of chemical resistance. Furthermore, the dip molding method has the drawback that it is difficult to manufacture gloves with a thick film, and it is difficult to improve chemical resistance by changing the film thickness.

Examples include methods of pulverizing it by freezing and pulverizing it or mechanically pulverizing it.

The volume average particle size of the powder can be within the range of particle sizes used in conventional powder compacting, for example, particle sizes of 100 to 500 μm can be used. Conventional powdered thermoplastic resins are used for shallow moldings such as automobile interior materials, but the molds for these applications are shallow and have large open areas, so powdered thermoplastic resins are It flows easily throughout the mold. On the other hand, gloves are deep molded products, and the mold has a narrow opening and is vertically long, making it difficult to spread the powdered thermoplastic resin all at once from the cuffs to the tips of the fingers. Therefore, it is important for the powdered thermoplastic resin used in the present invention to have high fluidity, and the volume average particle size is preferably 100 to 300 μm, more preferably 100 to 200 μm. Volume average particle size If the particle size is smaller than 100μm, the fluidity within the mold will be poor, and the powder may not reach the fingertips of the mold, or when the mold opening is returned downward after film formation. , excess powdered thermoplastic resin becomes difficult to remove. Moreover, when the volume average particle diameter is larger than 200 μm, it becomes difficult to manufacture gloves with a uniform thickness.

In the manufacturing method of the present invention, the method of contacting a heated glove mold with a powdered thermoplastic resin to form a resin film on the surface of the mold is not particularly limited. Examples include the so-called powder slush method, in which a thermoplastic resin is sprayed while powdering, and the so-called fluidized dipping method, in which a heated glove mold is immersed in a fluidized bed of powdered thermoplastic resin.

After forming a resin film on the mold surface as described above, remove excess powdered thermoplastic resin by air blowing, etc., cool it, etc., and if the powdered thermoplastic resin is not sufficiently melted. If there are any areas, reheat with a burner or the like to adjust the film formation condition, and then peel the resin film from the mold. In this way, thermoplastic resin gloves can be manufactured. On the inside of the glove of the present invention, for example, an anti-adhesive layer may be provided or pile may be electrostatically flocked in order to facilitate putting on and taking off the glove.

The reservoir tank is preferably provided with a stirring chamber 5 below the tank, as shown in FIG. 1(b). By providing a stirring chamber 5 and introducing air into it, the powdered thermoplastic resin 7 housed inside the reservoir tank 4 becomes fluid, and when the reservoir tank 4 connected to the mold 1 is rotated, Since the resin film 8 having a uniform thickness is formed on the inner surface A of the mold 1, gloves having a uniform thickness can be manufactured.

In addition, when the stirring chamber 5 is provided, the upper part of the stirring chamber 5 may be made of a perforated member, for example, a mesh member, and the powdered thermoplastic resin 7 may be rolled up by the introduced air. preferable. By doing so, it is possible to improve the dispersibility of the powdered thermoplastic resin when the mold 1 is rotated.

As another preferable embodiment of the production method of the present invention, a method using a fluidized immersion method (the mold is a male mold) will be explained with reference to the drawings.

A thermoplastic resin glove is obtained by dropping it into a tank 14, cooling the mold 11, and after cooling, inverting and peeling it off from the male mold.

Specifically, first, as shown in FIG. 3(a), the mold 11 including the frame member is heated to a predetermined temperature using hot air 12 by a heating means. Next, as shown in FIG. 3(b), the powdered thermoplastic resin 15 is placed in a fluidized tank 14 equipped with a porous partition wall 13, and a gas such as air is introduced from the lower part of the fluidized tank 14 through the partition wall 13. The powdered thermoplastic resin 15 is made to flow, and the mold 11 is immersed in it. During this immersion, immersion may be performed if necessary. As a result, the powdered thermoplastic resin 15 is melted on the outer surface C of the mold 11 to form a resin film 17. Next, as shown in FIG. 3(c), the mold 11 is pulled up from the fluidized tank 14, and the excess powdered thermoplastic resin 15 is dropped into the fluidized tank 14 by a cooling means 16 such as air blow and cooled. Next, as shown in FIG. 3(d), after cooling, the resin film 17 is reversely peeled off to obtain a thermoplastic resin glove.

After the mold 11 is lifted from the fluidized tank 14, it is immersed in an adhesive solution and then electrostatically flocked to create a pile to improve the texture, or immersed in a surface modifier solution to provide an anti-adhesive layer. It may also be possible to make it easier to attach and detach.

The thermoplastic resin gloves obtained in this way can be made thicker evenly than ordinary dip-molded products, so the film thickness can be made uniformly thicker, and the resulting thermoplastic resin gloves have high tensile strength and elongation at break, and are solvent resistant.

Test example 1
Evaluation of physical properties of gloves:
The gloves of Examples 1 and 2 and Comparative Example 1 were evaluated for thickness variation measurement, tensile test, sensory test for resistance to stuffiness, and solvent resistance using the methods shown below, and the results are summarized in Table 1. .

(Thickness variation measurement)
Measure the thickness of the middle finger tip, palm part, and cuff part of the obtained glove using a thickness meter "Digimatic Thickness Gauge 547-321" (manufactured by Mitutoyo Co., Ltd.), and calculate the difference between the maximum and minimum thickness values. It was uneven.

(Tensile test)
Using a lever-type press cutter (manufactured by Toyo Seiki Seisakusho Co., Ltd.), a test piece was punched out from the palm of the glove into a dumbbell shape No. 6 specified in JIS K-6251. This test piece was installed in a tensile tester Autograph AG-Xplus (manufactured by Shimadzu Corporation), and with the lower part of the test piece fixed, it was stretched vertically at a tensile speed of 500 mm/min until the center of the test piece broke. Towed. The tensile strength at break and elongation at break were measured.

(Moisture permeability test)
The top of a beaker containing 80°C water was completely covered with a film cut from the palm of a glove, and a glass petri dish was placed on top of the film with the bottom facing up. When the water vapor generated from inside the beaker passes through the membrane and condenses on the inside of the Petri dish, the bottom of the Petri dish becomes cloudy. Permeability was evaluated as the moisture permeation time, which was the time from when the Petri dish was placed until the inside of the Petri dish turned white and cloudy.

(Difficulty getting stuffy sensory test)
Ten subjects were asked to wear the gloves, and 30 minutes after wearing them, they were asked to rate the presence or absence of stuffiness on a five-point scale from A to E below. The stage with the largest number of participants was evaluated as the glove's resistance to stuffiness.

<Evaluation><Contents>
A: I didn't get stuffy at all.
B: There was hardly any steam.
C: Slightly stuffy.
D: It felt stuffy.
E: It was very stuffy.

(Solvent resistance (toluene))
The solvent resistance of the palm part of the obtained glove was tested by cutting a circular test piece with a diameter of 80 mm from the palm part and using toluene in accordance with European standard EN374-3. The breakthrough time was evaluated as Level 0 if it was 0 minutes or more and less than 10 minutes, Level 1 if it was 10 minutes or more and less than 30 minutes, Level 2 if it was 30 minutes or more and less than 60 minutes, and Level 3 if it was 60 minutes or more.
