Abstract

(57) [Summary] (Corrected) [PROBLEMS] To provide a base material having a wood grain or stone pattern surface even if the surface of the base material has a complicated shape. SOLUTION: By using a double-headed gun 2 which can spray two paints 3 and 4, respectively, a wood-like or stone-like mottled pattern 5 is formed on the surface of a base material 1 with a mixture of dark and light paints. It is formed by coating.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a base material having a mottled surface, and in particular, no matter what kind of complicated shape the wood surface or stone-shaped striped pattern on the base material surface and the mottled surface by painting with a soft touch With respect to the base material.

[0002]

[Prior art]

 Conventionally, the curl fitting method is generally known for surface processing that reproduces wood grain patterns and stone patterns.In this method, a water-soluble printing film film is processed into a molded product by water transfer. This is a process obtained by applying a top coat. There are also other in-mold construction methods.

On the other hand, a method of simple monochromatic coating is generally known for soft surface treatment of a base material that directly touches human skin.

[0004]

[Problems to be solved by the device]

 However, the curl-fit manufacturing method is a processing method in which the printing film film is transferred to a molded product, and there are molded products that cannot be transferred due to the shape of the molded product, so the application field is narrow. In addition, this has the drawback that the cost will be extremely high.

Further, the products manufactured by the in-mold method or a similar method have a defect that a pattern is extended and a color tone is thinned in a deep drawn portion, or a pattern of a pattern is extended and extended.

On the other hand, the method of coating with a single color has the drawbacks that the color tone is simple, the degree of freedom in design is low, the field of use is narrow, and the cost is high.

[0007]

[Means for Solving the Problems]

 An object of the present invention is to provide a base material on which even a surface of a base material having a complicated shape has a wood-grain pattern surface or a stone-grain pattern surface and a soft composite color is reliably formed. As a solution, the base material has a spotted pattern applied by spraying a paint on the surface using a double-headed gun.

That is, the first aspect of the present invention is to use a double-headed gun capable of spraying two paints separately, and to apply a woody or stone-like mottled pattern on the surface of the base material with a mixture of the light and light paints. According to the present invention, a two-headed gun capable of spraying two paints separately is used, and the base material surface is partially mixed with a light and shade paint containing resin beads. It is characterized in that it is applied and formed in a composite color.

[0009]

[Embodiment of device]

 Hereinafter, the present invention will be described with reference to the embodiments shown in FIGS.

FIG. 1 shows the spraying position of the double-headed gun on the base material, FIG. 2 shows the mottled pattern obtained by FIG. 1, and FIG. 3 shows an example of a non-planar coated surface.

As a method of coating the base material 1, first, for example, a double-headed gun 2 as shown in FIG. Dark paint 3 is poured into 2a while light paint 4 is poured into 2b. In this case, the dark paint 3 has a light brown color, and the light paint 4 has a dark brown color in order to obtain a wood grain color.

Next, the paints 3 and 4 are simultaneously ejected from the double-headed guns 2a and 2b, respectively, while the paints 3 and 4 are moved at right angles to the paper surface and sprayed on the base material 1. For spraying at this time, the air pressure of the double-headed gun 2 is lowered to make the paint into a droplet state, and the viscosity is extremely lowered to obtain a larger pattern. After application, the pattern changes more fluidly, giving a natural wood grain pattern or stone tone.

To add a more specific explanation, the positional relationship between the double-headed gun 2 and the base material 1 at this time is to maintain the height of about 20 cm for spraying. If it is within the range, the appearance of the pattern does not affect much.

Further, when the double-headed gun 2 is used under normal spraying conditions, the particle size of the paint sprayed from the tip of the gun becomes fine, so that a mottled pattern cannot be obtained in this state.

Therefore, in the present invention, the spraying pressure is drastically reduced from the normally used range to increase the particle size of the coating material for spraying, and the coating material has an extremely low viscosity. Natural woodgrain and stonegrain patterns 5 are formed.

The wood-grain pattern produced in this way is, for example, brown and black dots, and the stone pattern is, for example, white and black dots (marble).

As described above, by performing clear coating on the entire surface as the top coat, a deep wood grain pattern or a stone grain pattern can be obtained. That is, as a specific example, as shown in FIG. 2, the base material 1 having the light and dark woodgrain and stonegrain patterns 5 in which the paints 3 and 4 are mixed is formed on the entire surface.

In the case shown in FIG. 1, however, the case where the surface of the base material 1 is a flat surface has been described. For example, in the case of a curved surface base material 6a having a complicated curve forming the three-dimensional object 6 as shown in FIG. Also in the same manner as in FIG. 1, the base material has a wood-like or stone-like spot pattern 5 on the surface.

Further, the case where the two types of paints forming the mottled surface have the same shades of color has been described, but the shades are not limited to the same shade of shades, and the same shades of different shades are also required. It becomes the base material of the simulated surface.

The base material having five wood-like or stone-like mottled patterns is a decorative board for audio (escussion), a mat type (soft feeling when touched) automobile interior parts, or a clear type. It can be widely applied to automobile interior and exterior parts (having a glossy surface). The above is the description of claim 1, but also in claim 2, in the case of soft-tone coating, for example, a coated surface having a spot pattern of red in gray color or a spot pattern of gray in white is used. However, it is not possible to submit a color photograph as a drawing for application, so there is no difference from the case of FIG. Therefore, this kind of illustration is not made.

However, the double-headed gun 2 at this time has, for example, one white acrylic / urethane coating containing resin beads (particle size 2 to 5 μm) and the other gray acrylic / urethane coating containing resin beads (particles). The diameter is 2 to 5 μ). The texture obtained by this coating becomes soft depending on the material of the beads.

The application of these soft-tone coatings is performed, for example, on the toilet bowl 7, the toilet seat 8 and the lid 9 of which the plan view is shown in FIG. 4A and the side view is shown in FIG. Polycarbonate, ABS or acrylic is used as the base material.

[0023] Thus, the conventional toilet bowl has a soft touch with only the color of the material and therefore has a cold feel, while the application of the present invention has the appearance of warmth and softness at the same time. Especially in the case of the toilet seat 8, the skin feels soft and warm. In addition, soft paint can also be applied to tiles that are flat rather than curved.

[0024]

[Effect of device]

 As described above, according to the present invention, it is possible to obtain a mottled surface even on a base material having a curved surface such as a toilet bowl, even if the surface of the molded article has any complicated shape. . In addition, the mottled surface can be applied easily by using a double-headed gun, so that the construction is easy and the cost can be reduced.
