Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing interior products, particularly interior products in which a lacquer coating layer is formed on the surface of a glass substrate.

[0002]

2. Description of the Related Art Conventionally, for interior products such as panels coated with this kind of lacquer, wooden products made of natural wood are generally used, and after the surface is pretreated, lacquer is painted on it. It is manufactured by And in the lacquered panel as a high-grade material, in order to prevent uneven quality, expansion and contraction, etc. of the raw wood, so-called laminated plywood, which is made by cutting the raw wood into thin plates and adhering them together. Manufactured by using the wood of, which is pretreated and then lacquered.

Thus, as shown in FIG. 3, in the conventional lacquer coating process for wood products, as shown in FIG. And scratches on the surface of the wood
Six processing operations such as cloth stopping, polishing, and ground treatment are performed respectively, and in the next ground processing 2, three undercoats for spraying polyester surf acer, five treatments such as laying to dry the undercoat, and water polishing with paper. Do the work. Then, in the next intermediate coating step 3, nine processing operations such as repeated operations such as intermediate coating, polishing, and intermediate coating and laying down are performed to finish the product. Table 1 shows an example of work in the conventional cloth tensioning step 1 and the grounding step 2 and an example of the required number of days.

[Problems to be Solved by the Invention] However, conventional wooden panel products coated with lacquer require the above-mentioned various processes for the material wood, and most of the processes are handmade. Therefore, it is not suitable for mass production,
In lacquer painting, it is a pretreatment until the lacquer is painted,
36 complicated processes such as upholstery process and ground process, which require skillful process, lengthened the number of manufacturing days,
There is a problem that the cost becomes high. Although there is a colored glass from the past, as a manufacturing method thereof, by mixing several kinds of metal oxides in the glass material,
There are methods to make several different colored glasses and methods to apply epoxy resin paint on the glass substrate. In each method, the weather resistance and smoothness of the glass are maintained and the adhesion is solved. There was no better way.

[0006]

The present invention has been made to solve the above-mentioned conventional problems, and uses a glass material that can be mass-produced as its base, and its surface is The purpose is to provide a lacquer coating that has been considered impossible in the past, the gist of which is the process of applying a coating mixture of lacquer and silicone acrylic resin on the surface of the glass substrate. The method for manufacturing a glass interior product is characterized by sequentially performing a step of naturally drying it and a step of heating it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in FIGS. 1 is an enlarged sectional partial view of a panel which is an example of a glass interior product obtained by the method of the present invention, and FIG. 2 is a block diagram showing a coating process by the method of the present invention.

In the figure, reference numeral 1 is a glass lacquered panel manufactured by the method of the present invention. On the surface of a glass substrate 2, a base layer 3 of silicone acrylic resin and a lacquered layer 4 on its surface are provided. And are formed respectively. Here, since the glass substrate 2 is an inorganic substance, there is a problem that it causes an adhesion failure or a curing failure with the lacquer coating material that is an organic material. However, in the present invention, the lacquer coating layer 4 is used.
By interposing a layer of silicone-acrylic resin between and, the bond between the inorganic glass and the organic lacquer coating layer is further strengthened, and the above-mentioned adhesion failure and curing failure are eliminated. .

Here, the method of forming the base layer 3 of silicone acrylic resin and the layer 4 of lacquer coating on the surface of the glass base 2 will be explained. As shown in FIG. 2, in the degreasing treatment step E1, the glass base 2 is formed. Wipe off the surface of 2 with alcohol (methyl alcohol) etc. to remove oil, rust, dust, etc. adhering to the surface, and eliminate secondary adhesion, smoothness of the coating surface, and uneven coating. .

Next, in the top coating step E2, the top coating material is applied to the surface of the glass substrate 2 pretreated in the degreasing processing step E1. The composition examples shown in Table 2 are used. That is, for example, bright light (trade name) manufactured by Cashew Polymer Co., Ltd. is used as a lacquer base, and a curing accelerator containing an aromatic polyisocyanate as a main component is mixed therein at a ratio of about 2: 1. And in this paint liquid,
When a silicone acrylic resin is blended at a ratio of about 0.06%, a thinning solution 105 (trade name) manufactured by Cashew Polymer Co., Ltd. is added to this for the purpose of viscosity adjustment. Incidentally, the thinning solution, the shape and size of the coated body,
Also, change the amount of dilution depending on the temperature difference before use.

[0011]

[Table 2]

Then, the top coat paint having the above composition is applied to the upper surface of the glass base 2. Then, this is naturally dried at room temperature and then further heated at about 60 ° C. for 30 minutes to be cured. Then, as shown in FIG. 1, a base layer 3 of silicone acrylic resin is formed on the surface of the glass substrate 2, and a lacquer-coated layer 4 is formed on the base layer 3. This is because the specific gravity of silicone acrylic resin is heavier than that of lacquer,
It is considered that the lacquer-coated layer 4 and the silicone acrylic resin base layer 3 are formed above and below, respectively.

Here, in the drying step, the silicone-acrylic resin is a reactive group (methoxy group, ethoxy group, sersolup group) that chemically bonds with an inorganic substance in the molecule.
And the two different reactive groups chemically reacting with organic substances (vinyl group, epoxy group, methacryl group, etc.), the base layer 3 is an adhesive agent for the glass base 2 and the lacquer layer 4 To work. Therefore, the lacquer-coated layer 4 is fixed on the upper surface of the glass base 2, and a strong lacquer-coated surface free from hardening troubles and adhesion troubles can be obtained.

[0014]

As described above, the method of manufacturing a glass interior product according to the present invention includes a step of applying a coating material in which a silicone acrylic resin is mixed with lacquer to the surface of a glass substrate, and naturally drying the coating material. Since the process and the heating step are sequentially performed, the layer of lacquer coating can be reliably fixed to the glass substrate, and peeling and curing failures that could not appear in conventional glass products It is possible to obtain a glass interior product that does not have a deep, moist beauty and does not impair the transparency of glass. Further, since the coating process is simple, it is possible to enhance the productivity, and there are various effects that a uniform quality can be manufactured at low cost.
