Description

  The present invention relates to a resin-coated transparent body in which an intermediate material and a thermoplastic resin are laminated on the surface of a transparent body.

  In general, in order to improve the decorativeness of a transparent body such as a glass material, a method of sandwiching a resin sheet having various patterns between glass plates is often used. For example, a decorative laminated glass in which a resin sheet or the like is disposed between two glass plates and the two glass plates are partially bonded is known (see Patent Document 1). Moreover, in such a case, since resin etc. hold | maintained inside act as a protective film, it is utilized also for housing construction materials besides improving a decorative property. In particular, there is also a resin-inserted laminated glass to which crime prevention performance is added by strengthening against impact and penetration in windows and doors (see Patent Document 2).

  In any case, in a configuration in which a resin is combined with a transparent body such as a glass material, a resin sheet or the like is enclosed in a flat glass plate, so that it has been used only as a building material such as a glass window or a glass door.

  On the other hand, the demand for improving the decorativeness of transparent materials such as glass materials by taking advantage of the ease of processing of resin materials is also required for tableware products such as tableware in addition to conventional uses as building materials. It has become like this. However, when it is going to improve the decorativeness of tableware articles, such as tableware, the transparent body (glass material, transparent plastic material) used as the object is not necessarily a flat plate like a building material.

  Therefore, if the resin sheet is simply adhered to the transparent body according to a known production method, the aesthetic appearance may be impaired due to wrinkles. In particular, in tableware articles, aesthetics are emphasized, and the occurrence of wrinkles is fatal.

  Here, in tableware articles such as tableware, products using resin materials partially are already known. For example, there is a glass container suitable for recycling by applying a silane coupling agent, a thermoplastic resin, or the like (see Patent Document 3). Furthermore, a tableware in which a gasket made of silicone resin or the like is arranged on the bottom surface of the container and a resin sucker is arranged on the bottom surface of the container has been reported (see Patent Document 4). In the case of this patent document 4, the friction with a dining table etc. increases and it makes it hard to slide by arranging the resin member on tableware. These tablewares were mainly designed and used as nursing care products, with the primary focus being only on improving adhesion and frictional resistance with dining tables and the like. Therefore, in the above tableware, at present, sufficient decoration according to the user's preference is not achieved.

According to tableware articles such as tableware made of a conventional transparent body (glass material, transparent plastic material), three kinds of methods are mainly used for decoration. 1) a method of directly applying a pattern or coloring to the surface of the transparent body, 2) a method of directly applying a pattern or coloring to the surface of the transparent body, 3) a method of using a colored glass material or plastic material for the transparent body itself. In such a case, the production quantity per lot must be increased from the viewpoint of production efficiency. Therefore, it is difficult to form decoration individually according to each consumer's preference.

  The present invention will be described below with reference to the accompanying drawings. 1 is an overall perspective view of a resin-coated transparent body according to an embodiment of the present invention, FIG. 2 is a schematic cross-sectional view of the resin-coated transparent body of FIG. 1, and FIG. 3 is a resin-coated transparent body according to a second embodiment. FIG. 4 is a schematic diagram of a measuring device for the coefficient of static friction, FIG. 5 is a first schematic process diagram relating to the production of a resin-coated transparent body, and FIG. 6 is a second diagram relating to the production of a resin-coated transparent body. FIG. 7 is a schematic process diagram, and FIG. 7 is a schematic diagram showing peel strength measurement.

  The resin-coated transparent body of the present invention will be described with reference to FIGS. The example shown in the figure is a resin-coated transparent body 10 made by using a “table dish” as the transparent body 11. That is, as defined in the invention of claim 1, the resin-coated transparent body 10 has a structure in which the intermediate material 20 and the thermoplastic resin 30 are laminated on a part or the whole of the surface 12 of the transparent body 11. In particular, the resin-coated transparent body 10 exemplified here is laminated on an outer bottom surface 13 and an outer surface 14 which are part of the surface 12 thereof. The thermoplastic resin is not laminated on the inner bottom surface 15 and the inner side surface 16 other than the outer bottom surface 13 and the outer surface 14, and the transparent body 11 appears directly.

  More specifically, as can be understood from the schematic cross-sectional view of FIG. 2, in the resin-coated transparent body 10, the first thermoplastic resin 31, the intermediate material 20, and the second heat are formed on the surface 12 of the transparent body 11. The plastic resin 32 is laminated in order. In manufacturing this resin-coated transparent body, the thermoplastic resin 30 (the first thermoplastic resin 31 and the second thermoplastic resin 32) is impregnated into the intermediate material 20 to impregnate the thermoplastic resin 30. Is formed on the surface of the transparent body 11 including the intermediate material 20 to form the adhered resin layer 40. The first thermoplastic resin 31 and the second thermoplastic resin 32 penetrate into the intermediate material 20 by plasticization due to heating, and the respective resins are integrated to form an adherent resin layer 40 made of the thermoplastic resin 30. . In the figure, the symbol Lt indicates the thickness of the deposited resin layer.

In particular, the illustrated transparent body 11 is a glass material as defined in the invention of claim 2. As the composition of the glass material, in addition to widely used soda lime glass, an appropriate colorless and transparent glass material such as lead glass (crystal glass) or borosilicate glass is used. These glass materials also include tempered glass whose strength is increased by glass strengthening. Examples of glass strengthening include air-cooling strengthening in which air is blown and chemical strengthening in which ion exchange is mainly performed between Li ⁺ , Na ⁺ and K ⁺ . The glass strengthening method is appropriately selected in consideration of the shape, application, etc. of the target glass material.

  In addition to the tableware and ashtray of the examples to be described later, the shape of the glass material is expanded to building materials such as door glass, crime prevention glass and partition glass, and furniture such as glass top table, glass board and mirror by glass strengthening. be able to.

  Since the resin is laminated on the surface of the glass material, even if the transparent glass material is damaged, the adherent resin layer (thermoplastic resin) keeps the glass material fragments together, and the glass material fragments. Can be suppressed. In addition, when the glass material which is a transparent body and, for example, a table or the like come into contact with each other, an impact is absorbed by the coated resin layer, and generation of impact sound can be suppressed. Moreover, since the adherend resin layer acts as a buffer material, the effect of absorbing vibration is also exhibited. These functions and effects are also exhibited and advantageous even when used for building materials and furniture.

  The transparent body may be a transparent plastic material as defined in the invention of claim 3. This transparent plastic material is appropriate as long as it maintains colorless and transparent properties. For example, polycarbonate resin, polymethyl methacrylate, methyl methacrylate / styrene monomer copolymer, transparent polypropylene resin, transparent ABS resin, transparent polystyrene, transparent epoxy resin, polyarylate, polysulfone, polyethersulfone, transparent nylon resin, transparent polyethylene terephthalate , Transparent polybutylene terephthalate, transparent fluororesin, poly-4-methylpentene, transparent phenoxy resin, transparent polyimide resin, transparent phenol resin, fluorinated polyimide, ZEONEX (registered trademark), ZEONOR (registered trademark), ARTON (registered trademark) Etc. are listed.

  By making the transparent body a transparent plastic material as described above, the weight of the resin-coated transparent body itself can be reduced. Furthermore, processing can be performed freely as compared with glass materials. Of course, even when the transparent body is a transparent plastic material, it exhibits effects such as scattering prevention at the time of breakage, suppression of impact sound, absorption of vibration and the like, similar to the glass material.

  The above-mentioned intermediate material is required to be a material having high air permeability since the permeation of the thermoplastic resin plasticized by heating is taken into consideration. Therefore, as to the degree of impregnation of the thermoplastic resin, the air permeability can be defined as one index, as defined in the invention of claim 4. In the said air permeability, in the measurement based on the air permeability test prescribed | regulated to JIS-S-3102 (1992) using the Gurley test machine B type of JIS-P-8117 (1998), the passage time of air is 160 sec. The following is desirable. Here, JIS-S-3102 (1992) is a standard that defines a material having higher air permeability than ordinary paper such as shoji paper. In addition, since this intermediate material is exposed to the plasticized thermoplastic resin, it is necessary to consider that the material constituting the intermediate material does not cause problems such as heat denaturation.

  Therefore, as materials used for the intermediate material, in addition to various Japanese paper such as paper, especially shoji paper, cloud dragon paper, falling water paper, Echizen Japanese paper, Mino Japanese paper, textiles made of natural fibers such as silk, cotton, hemp, wool, polyester Textile fibers such as fibers and rayon are used. Examples of the woven fabric include Nishijin weave, Kaga Yuzen, Arimatsu squeeze, red pattern, cocoon, goblet weave, and lace. Further, a material such as a non-woven fabric, a glass fiber sheet, a carbon fiber sheet, a ceramic fiber sheet, a wire mesh, etc., that can sufficiently ensure air permeability and heat resistance is preferable.

  As described above, the intermediate material can be a material that makes use of a unique texture and taste. In addition, it can be newly processed into an intermediate material. For example, in addition to using self-made embroidery, patchwork can be made by bonding fabrics together. In addition, pressed flowers, vegetation, etc. can be sown into Japanese paper. Furthermore, a pattern can be formed on the above-mentioned Japanese paper or cloth (in addition to writing characters, pictures, etc., printing using an ink jet printer). Of course, these are only examples and are free for the purpose of improving the design of the intermediate material.

  The thermoplastic resin used in the present invention is transparent so as not to impair the appearance of the transparent body after molding, heat received during washing of the resin-coated transparent body, durability to chemicals (detergents, etc.), oxidation resistance In consideration of the tear strength and the like. Therefore, as specified in the invention of claim 5, urethane-based thermoplastic elastomers and ethylene-vinyl acetate-based thermoplastic elastomers are preferably used as the thermoplastic resin. In addition, ethylene-vinyl acetate rubber, polyolefin-based thermoplastic elastomer, ethylene-methyl methacrylate copolymer, and the like are also included.

  In particular, in the present invention, as defined in the invention of claim 6, it is desirable that the thickness of the adherend resin layer Lt (see FIG. 2) be 0.2 mm or more. The thickness of the adherend resin layer is appropriately set depending on the type of resin to be formed, the thickness of the intermediate material, the shape of the transparent body, the intended use, and the like. However, as described above, it exhibits sufficient effects in preventing scattering when the transparent body (glass material, transparent plastic material) is damaged, suppressing impact sound, absorbing vibration, etc., and considering the durability of the resin itself. For this reason, it is considered necessary that the thickness of the deposited resin layer be 0.2 mm or more. Moreover, although the upper limit of the thickness of the adherend resin layer is appropriate, it is approximately 2 mm or less. When the thickness of the adherend resin layer exceeds 2 mm, there is a concern that the adherence (adhesion) strength with the transparent body (glass material, transparent plastic material) may be reduced. Furthermore, it is pointed out that the thickness of the transparent body and the resin-deposited resin layer becomes poor, and the aesthetic appearance of the resin-coated transparent body may be impaired.

  In addition, as specified in the invention of claim 7, a thermosetting urethane-based resin is applied to the surface of the adherend resin layer, and a protective resin layer is formed by the thermosetting urethane resin. Therefore, in the resin-coated transparent body shown in FIG. 3, the coated resin layer 40B is formed of the first thermoplastic resin 31, the intermediate material 20, and the second thermoplastic resin 32, and further, (2) A thermosetting urethane resin 33 cured on the outside of the thermoplastic resin 32 is laminated as a protective resin layer 38. In the figure, reference symbol Lt ′ indicates the thickness of the combined resin layer and protective resin layer, and the thickness is 0.2 mm or more. Also, in FIG. 3, portions common to FIG.

  As shown in FIG. 3, since a protective resin layer made of a thermosetting urethane resin is provided separately, for example, in addition to physical obstacles such as impact, it is sufficient for strong alkali conditions using a cleaning liquid as in Examples described later. This can further protect and strengthen the deposited resin layer. Moreover, it is effective also in protecting the exposed part of the edge part which excised and grind | polished the surplus adherence resin layer and intermediate material (refer to the manufacturing method mentioned later). Incidentally, examples of the thermosetting urethane resin include an aqueous urethane-based thermosetting resin manufactured by Tsukisei Kasei Co., Ltd. and an aqueous block isocyanate type urethane resin manufactured by Mitsui Takeda Chemical Co., Ltd.

  Here, as specified in the inventions of claims 8 and 9, it is possible to evaluate the difficulty of slipping of the resin-coated transparent body itself using the static friction coefficient (static friction coefficient). Therefore, as will be apparent from the examples to be described later, in the resin-coated transparent body, the static friction generated between the coated resin layer or the protective resin layer and the wood, the glass plate, and the vinyl chloride resin in the dry state. Is preferably 0.4 or more.

In measuring the static friction coefficient (static friction coefficient), a friction coefficient measuring machine 100 shown in FIG. 4 was created and used. The friction coefficient measuring machine 100 combines a fixed base 101 and a wooden movable plate 102 with a hinge 106. When measuring the static friction coefficient between the resin-coated transparent body (coated resin layer or protective resin layer) and wood, the resin-coated transparent body W is placed directly on the wooden movable plate 102, and the movable plate 102 is gradually tilted. The inclination angle θ when the resin-coated transparent body W starts to move is measured. When tan θ (tangent of θ) is obtained from the inclination angle θ, this becomes the static friction coefficient μ _S between the resin adherend layer (or protective resin layer) and the wood.

  When the coefficient of static friction between the resin coating layer or the protective resin layer and the glass plate is obtained, the glass plate 103 is placed on the movable plate 102 and fixed by the support block 105, and then the resin is directly applied to the glass plate 103. The adherent transparent body W is placed, the inclination angle is measured, and the tangent is obtained. Similarly, when obtaining the static friction coefficient between the resin coating layer or the protective resin layer and the vinyl chloride resin plate, the vinyl chloride resin plate 104 is placed on the glass plate 103 and fixed by the support block 105, and then the vinyl chloride is obtained. The resin-coated transparent body W is directly placed on the resin plate 104, the inclination angle is measured, and the tangent is obtained.

  In the resin-coated transparent body having the above-described configuration, it becomes difficult to slip because the deposited resin layer or the protective resin layer is formed. In other words, this is an advantage that the frictional resistance is increased. Assuming that it is mainly used for tableware such as tableware, the resin-coated transparent body is not easily moved due to friction with the table. For example, when used as a tableware for nursing care, when a meal is held with a spoon with one hand, the table does not move carelessly. Therefore, it is not necessary to increase the weight of the tableware itself as in conventional care tableware, and the convenience of handling is improved. Moreover, in the case of tableware used in railway vehicles, ships, airplanes, etc., vibration can be absorbed by the deposited resin layer, and it can be prevented from moving carelessly when tilting. Of course, it goes without saying that there is a visual effect by providing a beautiful decoration as an intermediate material to the tableware for nursing care, the tableware used in the above-mentioned railway and the like.

  Based on the structure of the resin-coated transparent body of the present invention that has already been described, an example of a method for producing the resin-coated transparent body will be briefly described with reference to FIGS. In the figure, a glass table dish is used for the transparent body 11, and an adherent resin layer is formed on a part of the surface of the transparent body. In addition, parts common to those in FIGS. 1 and 2 are denoted by the same reference numerals. Of course, in the case of a shape other than the dish for a table, there is a possibility that the adherent resin layer is formed on the entire surface of the transparent body.

  As shown in FIG. 5 (a), the powdery thermoplastic resin 30 is applied to the surface of the transparent body 11 on which the surface 12 has been previously washed and dried by the appropriate resin spraying device 200. Sprayed or sprayed. In this example, the first thermoplastic resin 31 is sprayed (sprayed) to the outer bottom surface 13 and the outer surface 14 of the transparent body 11 that is a glass dish so as to have a uniform thickness. After spraying, the first thermoplastic resin 31 is heated to a temperature for plasticizing. Although the heating temperature varies depending on the type of resin, it is generally maintained at 90 to 110 ° C. for 5 to 20 minutes, and the resin is plasticized.

  Subsequently, as shown in FIG. 5B, the intermediate material 20 including the pattern 21 is arranged so as to be aligned on the first thermoplastic resin plasticized with heating. As shown, the pattern 21 is located on the outer bottom surface 13. In this case, the intermediate material including the pattern is Japanese paper. That is, the first thermoplastic resin plasticized (softened) into the inside of the intermediate material 20 penetrates, and the intermediate material just sticks to the first thermoplastic resin.

  Furthermore, as shown in FIG.5 (c), the powdery thermoplastic resin 30 (2nd thermoplastic resin 32) is sprayed (spread) by the said resin dispersion | spreading apparatus 200 again from the intermediate material 20. FIG.

  As shown in FIG. 6A, the integrated body of the transparent body 11, the intermediate material 20, and the first and second thermoplastic resins 31 and 32 is accommodated in a vacuum chamber 250 made of heat-resistant rubber. Each is heated at 90-110 ° C. for 5-20 minutes. Thus, the second thermoplastic resin 32 is plasticized, so that the first and second thermoplastic resins are plasticized (softened). Reference numeral 251 denotes an exhaust port of the vacuum chamber.

  Subsequently, as shown in FIG. 6B, the air inside the vacuum chamber 250 is exhausted from the exhaust port 251. The vacuum chamber 250 contracts while being bent and covers the transparent body 11 and the intermediate material 20. At this time, defoaming from the intermediate material and the thermoplastic resin proceeds, and at the same time, an equal pressure is applied to any surface according to the shape of the transparent body 11. Therefore, the intermediate material 20 is uniformly applied to the first thermoplastic resin on the surface of the transparent body 11, and at the same time, the second thermoplastic resin is equally impregnated in the intermediate material 20.

  As a result, the first and second thermoplastic resins are fused to each other by penetrating into the intermediate material 20 to form an adherent resin layer containing the intermediate material and adhere to the surface of the transparent body 11. In this case, the first thermoplastic resin and the second thermoplastic resin are the same resin.

  After cooling the resin, as shown in FIG. 6C, the excess intermediate material and resin at the edge of the transparent body 11 are cut off, and the resin-coated transparent body 10 is completed. In this case, the cut surface can be treated beautifully by performing buffing or the like on the cut surface of the edge of the transparent body.

  As described above, it goes without saying that a transparent plastic material can be used for the transparent body in addition to the examples shown and described. According to the exemplified manufacturing method, the resin to be deposited is in a powder form, but a resin sheet (not shown) can be used in the case of a relatively flat shape due to the curvature of the transparent body. In addition to processing the internal surface shape of the vacuum chamber made of the above heat-resistant rubber, by using a pressing die coated with a release agent, etc., the surface of the adherend resin layer to be formed is embossed, slitted, A stamp pattern or the like can also be formed.

  In addition, the transparent body is not limited to the illustrated dish, and may be an appropriate article such as a glass such as a cup or stemware, a seasoning container, a soy sauce container, a figurine, a vase, or an ashtray. In particular, by forming an adherent resin layer on the bottom surface of these articles, decorativeness, vibration and impact resistance, and sound absorption performance are imparted. Furthermore, for example, by forming an adherent resin layer on a part or the whole of a transparent body such as a paperweight or a doorknob, it is possible to have a new decoration and improve the grip feeling. In addition, it can be expanded to building materials such as door glass using tempered glass, crime prevention glass and partition glass, and furniture such as glass top table, glass board and mirror.

  As shown in this manufacturing method, an appropriate material and pattern can be appropriately selected and used for the intermediate material. Therefore, not only a single product is mass-produced as a resin-coated transparent body, but also a small amount of various types can be produced by suitably changing the intermediate material. For example, it is possible to meet the demand for souvenir plates such as gifts, glass with logotypes, glass plates for partitioning, and the like.

  If further added, it is also possible to carry a metal foil or glass fine powder on the above-mentioned intermediate material. That is, when a desired metal foil or glass fine powder is poured into Japanese paper, it is necessary to disperse it excessively in a Japanese paper raw material suspension. Or it will also be uniformly dispersed in the resin layer to be deposited, and the amount used will increase dramatically. However, according to the resin-coated transparent body of the present invention (the above-described production method), metal foil and glass fine powder may be appropriately dispersed between the first and second thermoplastic resins or in the intermediate material. The amount can be reduced. As such a material, Nippon Sheet Glass Co., Ltd. metal-coated glass flake: Metashine (registered trademark) can be used, and in a resin-coated transparent body containing the material, the color changes depending on the viewing angle. In addition, in a resin-coated transparent body containing strontium aluminate-based phosphorescent agent: N-Luminous Lumiclean (registered trademark) manufactured by Nemoto Special Chemical Co., Ltd., it will continue to shine after being extinguished.

[Measurement of air permeability of intermediate material]
About the paper which can be obtained from the city, the air permeability was measured based on the method using the Gurley tester B type of JIS-P-8117 (1998). The sample paper was allowed to stand for 4 hours or more under the conditions of 23 ± 1 ° C. and 50 ± 2% (RH) according to the pretreatment conditions of JIS-P-8111.

  Table 1 shows the air permeability measurement results of Yunlong paper, PPC paper, and recycled PPC paper. In the measurement, the air permeation opening diameter was φ28.6 mm, the passing air amount was 100 mL, and one sheet was stacked.

  As is clear from this result, the air permeability (air passage time) is extremely small in the Japanese paper (unryu paper) sample. Therefore, the inventors made the measurement according to the air permeability test prescribed in JIS-S-3102 (1992), and made the air opening diameter: φ10.0 mm, the passing air amount 200 mL, and two layers. In addition, the air permeability of Echizen Japanese paper cloud dragon paper, calligraphy half paper, Mino Japanese paper, and yellow cardboard was also measured, and the results are shown in Table 2. Furthermore, the air permeability of polyester fabric (printed product, dark blue, and light blue) was also measured and shown in Table 3. In Tables 1 and 2, the cloud dragon paper is common.

(Measurement of peel strength)
The above-mentioned intermediate material (the above-mentioned various Japanese papers) and a thermoplastic resin were laminated on the surface of two plate-like glasses to form an adherent resin layer. In addition, ethylene-vinyl acetate type | system | group thermoplastic elastomer (modified | denatured ethylene-vinyl acetate copolymer): Takemelt powder PW-900 (softening point: 50 degreeC) by Mitsui Takeda Chemical Co., Ltd. was used for the thermoplastic resin. The thickness of the plate glass was 5 mm and the width was 20 mm. In forming the adherend resin layer, the glass dish was changed to plate-like glass in accordance with the method for producing a resin-coated transparent body shown in FIGS. The heating conditions were 100 ° C. maintained for 10 minutes and 106 ° C. maintained for 10 minutes. Further, air was sucked until the degree of vacuum in the heat-resistant rubber vacuum chamber was -0.095 to -0.1 MPa.

  About the sample piece which formed the adherence resin layer on the surface of two sheet glass, as shown in FIG. 7, two sheet glass was arrange | positioned at right angle so that a line contact might be carried out by the adherence resin layer. And while fixing the sheet glass containing one adherence resin layer, the sheet glass containing the other adherence resin layer is pulled, and the adherence resin layer formed in the sheet glass surface is from plate glass. The tensile force (kg) at the time of starting to peel was measured.

  In FIG. 7, reference numeral 150 is a glass-coated resin-coated transparent body, 151 is a tension-side plate-shaped glass, 152 is a fixed-side plate-shaped glass, 130 is a deposited-side resin layer, 131 is a tension-side deposited resin layer, and 132 is fixed Side-attached resin layer, 300 indicates a fixing member, and F1 indicates a tensile direction.

  Table 2 shows the values at the time of peeling for each sample piece, that is, the tensile force (kg) as the peel strength.

[Evaluation of deterioration test]
Each sample piece used for the measurement of peel strength was left outdoors for 6 months, and the change in appearance was visually evaluated. The results are also shown in Table 2. In the evaluation, “A” indicates that there is no change in appearance, “B” indicates that water slightly permeates from the end, “C” indicates that some peeling occurs, and “D” indicates that the peeling amount is large.

  As is clear from the above results, both Japanese paper and polyester cloth obtained good air permeability. Moreover, the sample piece of Japanese paper in which good air permeability was ensured showed suitable properties in peel strength and deterioration tests. Then, in the measurement based on the air permeability test prescribed | regulated to JIS-S-3102 (1992) using the Gurley test machine B type of JIS-P-8117 (1998), the air permeability of the said intermediate material is 160 sec or less. It can be said that it is desirable.

[Prototype Example 1]
The transparent body is a glass plate manufactured by Ishizuka Glass Co., Ltd .: Plate 180 (a disk shape having a diameter of 18 cm and a weight of 280 g), and the modified ethylene-acetic acid manufactured by Mitsui Takeda Chemical Co. Vinyl copolymer: Bamboo melt powder PW-900 (softening point: 50 ° C.), and the above-mentioned Unryu paper (basis weight: 84.3 g / m ² ) was used as an intermediate material.

  The above-mentioned thermoplastic resin was sprayed on the outer bottom surface and the outer surface of the glass dish, and it was carried into a heating furnace (electric furnace) and maintained at 100 ° C. for 10 minutes to plasticize (soften) the thermoplastic resin. Then, the dragon paper (intermediate material) was put on the resin quickly taken out of the furnace and plasticized, and the thermoplastic resin was sprayed again from the dragon paper. Subsequently, the glass pan, the intermediate material, and the thermoplastic resin are accommodated in a heat-resistant rubber vacuum chamber, and the heat-resistant rubber vacuum chamber is carried into a heating furnace (electric furnace) and maintained at 106 ° C. Heated. During this time, air was sucked until the degree of vacuum in the heat-resistant rubber vacuum chamber was -0.095 to -0.1 MPa. Thus, the heat-resistant rubber vacuum chamber was contracted and bent in accordance with the shape of the glass dish, and the thermoplastic resin and the cloud paper were integrated to form an adherent resin layer. This was about 10 minutes.

  The heat-resistant rubber vacuum chamber was taken out of the heating furnace and allowed to stand until it reached room temperature, and the glass dish on which the adherend resin layer was formed was taken out of the heat-resistant rubber vacuum chamber. Next, an excessive adherence resin layer was cut off and the cut surface was buffed. The weight of the resin-coated transparent body of the glass dish thus completed was 290 g, and the thickness of the deposited resin layer was 0.2 mm.

[Prototype Example 2]
Instead of the glass dish which is the transparent body of Prototype Example 1, a glass ashtray manufactured by Ishizuka Glass Co., Ltd .: Alpha ashtray beans (substantially square having a circular portion on the bottom with a side of 10 cm and a weight of 260 g) was used. The thermoplastic resin and the intermediate material were the same as those in Prototype Example 1.

  In Prototype Example 2, the formation of the resin coating layer is the same as in Prototype Example 1. However, the resin deposition layer was formed only on the circular part of the bottom surface of the ashtray. The weight of the resin-coated transparent body of the finished glass ashtray was 270 g, and the thickness of the deposited resin layer was 0.3 mm.

[Prototype Example 3]
A water-based urethane thermosetting resin manufactured by Tsukisei Kasei Co., Ltd. was applied with a brush to the surface of the resin layer of the resin-coated transparent body prepared using the glass dish which is the transparent body of Prototype Example 1. And it carried in in a heating furnace, maintained at 110 degreeC for 10 minute (s), and heated, and formed the protective resin layer (prototype example 3a). As another condition, after applying the resin, heating was performed while maintaining 130 ° C. for 10 minutes to form a protective resin layer (Prototype Example 3b). Furthermore, an aqueous block isocyanate type urethane resin manufactured by Mitsui Takeda Chemical Co., Ltd .: Takenate XWB-76-CA011 is formed on the surface of the resin layer of the resin-coated transparent body prepared using the glass dish which is the transparent body of Prototype Example 1. Was applied with a brush, carried into a heating furnace and heated at 130 ° C. for 10 minutes to form a protective resin layer (Prototype Example 3c).

[Evaluation of chemical resistance of coated resin layer]
The dish washing conditions by the commercial dishwasher were reproduced for the four types of resin-coated transparent bodies of the prototype 1 and the prototype 3 (3a, 3b, 3c). As the cleaning agent, SUMA / L52 (sales: Diversity Bar Co., Ltd.) was used, and diluted to 0.3% to obtain a cleaning solution (pH 12.5). The cleaning liquid was heated to 75 ° C., and the four types of resin-coated transparent bodies were immersed for 18 hours.

  As a result, the coated resin layer consisting only of the modified ethylene-vinyl acetate copolymer of Prototype Example 1 was whitened as a whole, and deterioration of the resin was observed. Some whitening was observed in part of the deposited resin layer on which the protective resin layer of Prototype Example 3a was formed. No change was observed in the deposited resin layer on which the protective resin layers of the prototypes 3b and 3c were formed. Further, in order to examine the influence of temperature, the four types of resin-coated transparent bodies were immersed in warm water at 75 ° C. for 18 hours. In this case, no change was observed in any of the resin-coated transparent bodies.

  According to the evaluation, it is effective to separately apply a thermosetting urethane-based resin (in the examples, water-based urethane-based thermosetting resin, water-based blocked isocyanate type urethane resin), particularly when exposed to strong alkaline conditions. You can say that. However, in the case where it is not exposed to a strong alkaline cleaning liquid as in the presented tableware cleaning conditions, it has a function comparable to that of the deposited resin layer of Prototype Example 1.

[Measurement of static friction coefficient]
As described above, the coefficient of static friction on the three types of contact surfaces of wood, glass plate, and vinyl chloride resin plate in a dry state was measured using the friction coefficient measuring machine shown in FIG. As a measurement object, the glass pan of Prototype Example 1 (plate 180), the glass ashtray (Alpha ashtray beans) of Prototype Example 2, and the glass plate of Prototype Example 3 (two types of heating conditions: 3a, 3b) were used. In addition, the same measurement was performed on a glass plate (plate 180) and a glass ashtray (alpha ashtray beans) before forming the adherent resin layer. Table 3 shows the inclination angle and the static friction coefficient when the six products start moving. The temperature at the time of measurement was 25 ° C., and the humidity was 50% RH. In the table, the inclination angle when starting to move is expressed as θ (degrees), and the coefficient of static friction is expressed as μ _S (that is, μ _S = tan θ).

  As understood from this result, the static friction coefficient is 0.4 or more in any of the wood, the glass plate, and the vinyl chloride resin plate in the article in which the adherend resin layer (including the protective resin layer) is formed. is there. That is, it can be seen that the transparent body (the glass article of the example) used for the measurement is less slippery because the adherent resin layer (including the protective resin layer) is formed on the surface of the transparent body.
