Fillers such as calcium carbonate, glass powder, and silica powder are blended with acrylic resin such as No. 111 resin, dispersed and put into a mold, and cured under the action of heat and/or a catalyst to form a molded product. Obtaining is a well known technique. This technique yields molded products with smooth surfaces and is used in the production of molded products such as wash basins, bathtubs, and table tops. In addition, in recent years there has been an increasing demand for molded products with beautiful surface finishes, and after spraying a mist of paint onto the mold surface using a spray gun to create a kiln-like pattern or satin-like pattern, the compounded resin is applied inside the mold. Molded products having a smooth and beautiful surface pattern are now being provided by putting them into water and curing them under the action of heat and/or catalysts (see Fig. 5).

浴槽が製造した。On the other hand, there is a strong demand for patterns with large grains, such as those found on colored stone sea bream, but this has not been possible with conventional techniques. The reason is that washbasins and bathtubs are three-dimensional objects, with vertical and sloping parts, and when droplets adhere to these parts, they move in the direction of gravity, causing so-called drips, resulting in unnatural patterns. It's for a reason. The present invention has been made in view of the above circumstances, and its purpose is to manufacture a molded product having a pattern of large diameter particles such as a colored stone sea bream. [Means for Solving Problem i1] The method of molding a molded article having a pattern on its surface according to the present invention involves forming a pattern by attaching droplet-shaped particles 2 to the surface of a mold 1, and then applying a curable composition. This is a molding method in which a material is put into a mold 1 and hardened to form a pattern on the surface of the molded product. [Effect 1] Since the droplet-like particles 2 are attached to the surface of the mold 1 to form a pattern, this pattern is formed on the molded product. It is possible to embody the pattern of colored stone sea bream which is integrally transferred and consists of particles 2 with large diameters.The present invention will be described in detail below.The mold 1 is for molding a bathtub, As shown in the figure, it consists of a lower mold 1a and an upper mold 1b, and a piping 3 for a liquid medium for heating is buried near the surfaces of the lower mold 1a and upper mold 1b. Droplet-like particles 2 are attached.This is done by diluting spray paint, which is a mixture of thermosetting resin with fillers, pigments, etc., with a solvent and spraying it with a spray gun 4, as shown in Figure 2. Droplet-shaped particles 2 are attached to 1a. Examples of thermosetting resins include unsaturated polyester resins, acrylic resins such as methyl methacrylate resins, phenolic resins, and area resins.For bathtubs, hot water-resistant An excellent methyl methacrylate resin is preferable. Examples of the filler include silica powder, thin powder, calcium carbonate, etc. Among them, silica powder with high strength is preferable.Also, as a pigment, organic pigments such as acrylic pigments, Inorganic pigments such as titanium oxide, iron oxide, or a mixture of these are used.For example, spray paint is prepared by blending 30 parts by weight of methyl methacrylate resin, 70 parts by weight of silica powder, and 5 parts by weight of pigment. , a suspension diluted with xylene (viscosity 10 cp) was sprayed at a pressure of 0 using a spray gun 4 with a diameter of 2.5 m.
Lower mold 1a heated to 70℃ or higher at 2 kg/cm2
to deposit droplet-shaped particles 2. in this case,
The droplet-shaped particles 2 were formed into a thin layer of spray paint because the diluent immediately volatilized. When we measured their diameters, we found that a considerable number of them had diameters of 2 ms+ or more. In this way, spray paint is sprayed by controlling the density, changing the pigment, and sequentially spraying spray paints with different brightness, tone, and hue onto the surface of the lower mold 1a, and spraying multiple types of spray paint with different tones and particle sizes. Droplet-shaped particles 2 were deposited. For example, the first spray paint sprayed is one shade lighter than the third (L*=34.89, a zero=-0,
02, bning = -0°16), the second spray paint is the second lightest gray (L = 47.61.at =
0.71, b = 1.48), the third spray paint is the lightest gray and seasoned (L car = 5
2.55, a* = 2.06, b book = 3.07), the fourth spray paint is the darkest gray (L car = 27.
36, car a=-0,60S b*=-1,05). After that, the upper mold 1b and the lower mold 1a were combined and a casting resin was poured into them. As the casting resin, it is possible to use a thermosetting resin such as an unsaturated polyester resin, an acrylic resin such as methyl methacrylate resin, a phenol resin, or an area resin, mixed with a filler and, if desired, a pigment. in this case,
It is preferable to use the same resin as that of am particle 2.
Next, it is heated at 60 to 90°C for about 30 minutes to harden under the action of a catalyst (peroxide), and is demolded to form a colored stone-like m-ridge as shown in Figures 3 and 4. This creates a bathtub with a smooth and beautiful surface.
本発明にあっては、金型表面に液滴状の粒子を付着させ
て模様を形成するので、この模様が成形品に一体的に転
写され、径の大きい粒子からなる有彩石調の模様を具現
できるものであり、しかも色調及び粒径が異なる少なく
とも二種の液滴状の粒子２を付着させるので、色調及び
形状が異なる多様な有彩石調の模様を現出させることが
できるものである。In the present invention, since the pattern is formed by attaching droplet-like particles to the mold surface, this pattern is integrally transferred to the molded product, resulting in a colored stone-like pattern made of large-diameter particles. Moreover, since at least two types of droplet-shaped particles 2 with different tones and particle sizes are attached, it is possible to create various chromatic stone-like patterns with different tones and shapes. It is.
