BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material whose surface layer is made of water glass.

0002

2. Description of the Related Art Generally, veneer plywood has been used in many cases as a decorative material to give a beautiful finish to the interior of building frames and the surfaces of fixtures. The veneer plywood is preferably coated with a hard resin layer in order to prevent scratches, stains, and material deterioration on the outermost layer. The hard resin layer was colorless and transparent, and was also useful for imparting depth, gloss, or specularity to its surface.

0003

[Problem to be solved by the invention] The hard resin layer formed on the surface of veneer plywood is still resin, no matter how hard it is made, and is resistant to impact and abrasion with high surface pressure. It was not possible to completely prevent the occurrence of scratches. At the same time, since it is made of resin, it lacks nonflammability and heat resistance, or if it does have it, its performance is poor, and in this respect its function as a building material is not fully satisfactory.

The present invention has been made in view of the above circumstances, and has significantly improved performance in preventing scratches, stains, material deterioration, etc., and is also highly expressive in surface texture, and can be used as needed. The purpose of the present invention is to provide a new decorative material (hereinafter referred to as the present decorative material) with a surface layer made of water glass, which can also be made nonflammable and heat resistant.

[0005]

[Means for Solving the Problems] The gist of the present decorative material is that a surface layer made of water glass is provided on a substrate made of wood, paper, plaster, resin, or the like.

[0006]

[Operation] Water glass hardens when the water contained in it is removed by evaporation or absorption. The hardness in this cured state is incomparably higher than the hard resin layer of conventional decorative materials, and even slight impact or abrasion will not cause scratches. Furthermore, water glass is highly transparent and glossy, and can be easily colored as desired, and furthermore, various surface textures can be expressed by adjusting the viscosity. On the other hand, if a noncombustible material such as gypsum is used as the substrate, the decorative material as a whole will have a noncombustible function.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to drawings showing embodiments thereof. FIG. 1 is a perspective view showing the manufacturing situation of the present decorative material. The present decorative material can be manufactured by applying water glass 2 to a substrate 1. In this example, gypsum board was used as the substrate 1. Therefore, the surface of the substrate 1 to which the water glass 2 is applied is preferably flattened in advance by polishing or the like, and also coated with a sealer (undercoating material for sealing) to improve smoothness. Furthermore, as the pattern layer 3, printing paper,
It is also possible to give the substrate 1 an expression by laminating colored paper, veneer, woven fabric, non-woven fabric, resin sheet, metal foil, etc., or by applying paint.

On the other hand, the water glass 2 contains 1 mol of Na2O
2 to 4 mol of SiO2 is contained therein. The thickness of the water glass 2 applied to the substrate 1 can be changed as desired, but in order to make it thinner, the viscosity of the water glass 2 must be lowered to increase the spreadability during application. On the other hand, to make it thicker, increase the viscosity of the water glass 2 so that it can be applied thickly. water glass 2
The viscosity of the water glass 2 can be easily adjusted by changing the amount of water mixed. By gradually adding water and stirring, the water glass 2 can be adjusted to an appropriate state as it changes from candy-like to liquid-like. All you have to do is find it. Note that the water glass 2 can be colored from transparent to opaque by mixing a coloring agent (such as a pigment).

[0009] When applying the water glass 2 to the substrate 1, it is preferable to heat the substrate 1 prior to the application operation. This is because by heating, the water content is easily removed from the water glass 2 after application, and its curing is performed quickly. The heating temperature varies depending on the material and structure of the substrate 1, the presence or absence of the pattern layer 3 (such as the above-mentioned printed paper or veneer), and the material of the pattern layer 3 applied to the surface of the substrate 1. temperature is 50-50
Select within the range of 0°C. However, water glass 2 is about 10
When heated above 00℃, it becomes vitrified, but since vitrified materials tend to become too hard to be used as building materials, it is necessary to avoid this situation. be. The heating method may be any suitable one, such as transporting the substrate 1 into a heating furnace using gas or other combustible materials, electricity, electromagnetic waves, ultrasonic waves, optical beams, etc.
Steam may be jetted onto the surface of the substrate 1, or the substrate 1 may be immersed in hot water. Note that when a heating method using steam or hot water is used, moisture is supplied to the substrate 1, so it is preferable to adjust the amount of moisture added to the water glass 2 to a small amount.

[0010] To apply the water glass 2 to the heated substrate 1, it is most reliable to use a flow coater (curtaining device), a sprayer (spraying device), or a roll coater (transfer device). There is also the advantage of uniform quality. It goes without saying that in addition to this, manual methods using a squeegee or brush painting can be employed.

[0011] By the way, the substrate 1 is not limited to gypsum board, but may also be made of wood such as veneer plywood, solid wood board, flash material (plywood bonded to a wooden frame), particle board, etc. It can be replaced with a single or composite lamination of sheet materials made of paper, woven fabric, non-woven fabric, or resin. In this way, the configuration and shape of the present decorative material can be changed as appropriate depending on the mode of implementation.

0012

[Effects of the Invention] As is clear from the above explanation, the decorative material having a surface layer made of water glass according to the present invention has a hardness in a state where the water glass is hardened, which conventional decorative materials do not have. Since the height is incomparably higher than that of a hard resin layer, even a slight impact or abrasion will not cause scratches. Of course, the ability to prevent dirt and material deterioration is also greatly improved. Water glass is also highly transparent and glossy,
If desired, it can be easily colored, and furthermore, various surface properties can be expressed by adjusting the viscosity. Furthermore, if a noncombustible material such as gypsum is used as the substrate, the decorative material as a whole can have a noncombustible function. Furthermore, since water glass is extremely inexpensive compared to hard resin materials and the like, it has many excellent advantages, such as making it possible to significantly reduce the manufacturing cost of the decorative material as a whole.
