【Example】
( Reference example )
Hereinafter, a reference example of the present invention will be described with reference to FIG.
[0017]
FIG. 1 shows a partial cross-sectional view of a bathroom washing place. The base material 1 is a layer obtained by press-molding an SMC material composed of an unsaturated polyester resin, glass fiber, and an inorganic filler, for example, by a known method. Then, after spraying an adhesive (not shown) that firmly adheres the washing surface 2 and the fine spherical particles 3, the fine spherical particles 3 are sprayed on the surface 2 of the washing place, which is coated with the fine spherical particles 3. Get.
[0018]
The above reference example describes an example of spraying an unshown adhesive that firmly attaches the washing surface 2 and the microspherical particles 3 as one of the coating methods, and other methods may be used. It suffices if fine spherical particles are coated.
[0019]
The microspherical particles 3 include polymethacrylic acid true spherical fine particles, polyethyl methacrylate true spherical fine particles, crosslinked polymethyl methacrylate true spherical fine particles, crosslinked polystyrene true spherical fine particles, and crosslinked polyacrylic ester true spherical fine particles. Further, it is possible to use a resin molded body such as a spherical fine particle of crosslinked polybutyl methacrylate or an inorganic spherical fine particle such as a glass bead.
[0020]
In particular, by using the fine spherical particles made of the above-described resin molded body, the wear resistance of the surface of the washing place can be dramatically improved.
[0021]
As the base material 1 for the washing place, a layer obtained by press-molding the SMC material, an FRP shaped body in which the surface of the washing place by the hand lay-up method or the resin injection method becomes a gel coat layer, or a shaped body injecting dicyclopentadiene Layer.
[0022]
By adopting such a configuration, it is possible to impart high surface hardness to the washing place by coating the fine spherical particles, and satisfy the performances such as warm water resistance, abrasion resistance, and chemical resistance as the washing place. You can get a washing place. Furthermore, since the microparticles are spherical, safety is ensured without any damage to the user's skin in the space used by the user naked, such as a bathroom washing place, unlike the sharp particles.
[0023]
Although FIG. 1 shows a partial cross-sectional view of a washing place made of a flat-shaped base material, the same applies even when unevenness is provided for preventing slipping in a timely manner.
[0024]
(Example 1 )
FIG. 2 shows a partial cross-sectional view of the bathroom washing place according to the first embodiment of the present invention. The base material 1 is a layer similar to the reference example . Then, a paint containing microspherical particles 3 is sprayed onto the surface 2 of the washing place with a spray gun or the like, and a coating layer 4 is formed on the surface 2 of the washing place. In the coating layer 4, a bathroom washroom having a configuration in which the fine spherical particles 3 are included as shown in the figure is obtained.
[0025]
As the paint, a paint having good adhesion performance to the material of the base material 1 on the surface of the washing place 2 and having water resistance may be selected, and examples thereof include urethane paint and acrylic urethane paint.
[0026]
The bathroom washing place obtained in this way provides the same effects as the reference example .
[0027]
Further, the use of the paint has an advantage that the fine spherical particles can be fixed to the surface of the washing place by a simple method of spraying the paint onto the surface of the washing place.
[0028]
As the size of the microspherical particles, if the diameter is 2 μm to 100 μm, high surface hardness can be imparted while maintaining the state of the washing field surface. In general, it is preferable to use microspherical particles having an average particle diameter in the range of 5 μm to 50 μm in a timely manner.
[0029]
When the fine spherical particles are added to the paint and the surface of the washing place is coated with the paint using the fine spherical particles by coating the paint, the range in which the fine spherical particles are contained in an amount of 2 to 10% by weight based on the paint. Is suitable. If it is less than 2% by weight, it is difficult to impart a high surface hardness.
[0030]
FIG. 2 shows a state where the microspherical particles are smaller than the coating film thickness and the size of the microspherical particles.
[0031]
On the other hand, as shown in FIG. 3, if the fine spherical particles are larger than the thickness of the coating film and the fine spherical particles, the wear resistance performance of the fine spherical particles can be expressed from the initial use stage. is there. Also, as shown in FIG. 3, when several kinds of micro spherical particles are combined, the performance from the initial stage of use and even if the micro spherical particles drop off, the smaller micro spherical particles are the next wear resistance performance. It has the feature that can be expressed.
[0032]
In particular, when the wear resistance performance was compared between the case where fine spherical fine particles made of a resin molded body were mixed in the paint and the case where the paint was mixed, it was found that the wear resistance of the surface of the washing place was dramatically improved.
[0033]
(Example 2 )
Furthermore, Example 2 is demonstrated using FIG.
[0034]
A step of applying a base coat layer 5 made of a monochromatic acrylic urethane-based paint A to the base material 1 similar to the reference example is provided. For paint A, add 4 parts of the main agent based on acrylic polyol pre-added with a gray pigment, 1 part of a curing agent based on transparent hexamethylene diisocyanate and an appropriate amount of thinner, and adjust the viscosity to about 15 seconds. It was composed by doing.
[0035]
The base coating layer 5 was formed by raising the normal atomization pressure to make the coating material into fine particles and coating the surface of the washing area by about 20 microns. Next, paint B (dark gray, viscosity 10 seconds) and paint C (white, viscosity 10 seconds) of different colors from paint A were prepared. Then, it provided the process of the pattern painting 6 by spraying particulate is low under the atomization pressure, respectively. The pattern coating 6 was adjusted so that the size of the coated particles was about 10 mm or less.
[0036]
In this way, as shown in the pattern diagram of the pattern on the surface of the washing place in FIG. 5, paint B ( 8 ) and paint C are applied sparsely on the surface and the paint and color of paint A ( 7 ) on the base coat layer are applied. It was painted so that both of the color of ( 9 ) can be seen. The material components of the coating material B ( 8 ) and the coating material C ( 9 ) are almost the same components as the coating material A ( 7 ). Therefore, after providing a waiting time of about 10 minutes, the coated bath was left in a drying furnace at 80 ° C. for 60 minutes to evaporate the thinner and harden the acrylic urethane paint.
[0037]
Next, the washing place is taken out from the curing furnace, cooled at room temperature for about 60 minutes, and then fine spherical particles made of crosslinked polymethyl methacrylate true spherical fine particles having an average particle diameter of 20 μm are formed on a transparent acrylic urethane coating. By adding 5% by weight, a step of applying a clear coat layer 10 of about 20 μm was performed by applying a semi-transparent paint while increasing the normal atomization pressure. Then, after providing a waiting time of about 10 minutes, a drying step for curing the acrylic urethane coating was provided by leaving the painted bath in a drying oven at 80 ° C. for 60 minutes. Then, the washing place with a pattern was obtained by cooling.
[0038]
In this way, a plurality of different colors of paint can be granted a new pattern pattern of pebble and Mikage tone to the washing place the surface of the pattern painted on the state it was Barama mottled point-like to the washing area surface, and washing place Can be obtained that satisfy performances such as resistance to warm water and chemical resistance.
[0039]
As described above, acrylic urethane paint is used for pattern coating as described above. By doing in this way, the adhesiveness of the FRP washing place which consists of SMC, and a coating material was securable, and it did not peel or swell in a warm water test etc.
[0040]
