Description

TECHNICAL FIELD The present invention relates to an FRP molded product used for a bathroom unit or the like.

2. Description of the Related Art As a conventional method for attaching a pattern to an FRP molded product, a structure in which a pattern-printed paper or a non-woven fabric 9 is enclosed immediately below the clear resin 8 as shown in FIG. It was common to take.

Problems to be Solved by the Invention However, such a structure not only increases the material cost because printed paper or non-woven fabric must be used, but also causes wrinkles on the paper or non-woven fabric in the manufacturing process. However, it took a long time to perform positioning, and the configuration was not productive at all.

Means for Solving the Problems And the technical means of the present invention for solving the above problems have a surface having irregularities, and the surface layer is a semitransparent resin layer containing a slight amount of pigment, and a second layer. A colored resin layer is placed on the eyes,
The third and lower layers are formed by impregnating glass fibers with a resin and laminating the layers.

Action The action of this technical means is as follows.

That is, since the surface layer formed on the mold surface having irregularities is formed such that the wall thickness is thin in the convex portions and thick in the concave portions according to the unevenness of the irregularities, when viewed from the surface, the Since the transparency is different, a slight change occurs in the appearance of the color of the second layer, and when viewed as a whole, it looks as if a pattern was attached.

Embodiment One embodiment of the present invention will be described below with reference to FIGS. 1 to 3 of the accompanying drawings. In this example, a wall material for a bathroom unit was used, and a FRP hand layup method was used as a processing method.

In the figure, reference numeral 1 is a bathroom unit, and a wall member 3 is erected around a floor 2. This wall material 3 is an FRP molded product molded by the hand lay-up method. Reference numeral 4 is a surface layer, which has irregularities 5 transferred from the molding die, and a slight amount of pigment is added to the clear resin. Table 1 shows the composition of the surface layer and the curing conditions.

Reference numeral 6 is a second layer, which is a colored layer, and is made of a material obtained by coloring an isophthalic acid-based unsaturated polyester resin. 7 is the third
The layer is formed by impregnating and laminating 900 g / m ² of glass fiber with orthophthalic acid-based unsaturated polyester resin, and curing.

Since the surface layer 4 is formed by being applied to a mold having irregularities, the surface layer 4 flows until it hardens so that it accumulates in the recesses of the mold, resulting in a thick film thickness, and conversely, the convex parts have a thin film thickness. Become. As a result, in the molded product transferred from this, the film thickness of the convex portion becomes thicker and the film thickness of the concave portion becomes thinner.

Under such a structure, since the light transmittance changes depending on the difference in the thickness of the surface layer, the appearance of the color of the second layer 6 is different between the convex portion and the concave portion, and a pattern is formed as a whole. The bathroom unit made of a wall material made of such a molded product has a different appearance on the wall surface, and it can be removed from the dry interior of the conventional unit bath.

EFFECTS OF THE INVENTION As is clear from the description of the above-mentioned examples, the present invention has a surface having irregularities, a semi-transparent resin layer containing a slight amount of pigment in the surface layer, and a colored resin layer in the second layer. Since it is a patterned FRP molded product that is arranged and laminated on the third layer and below by impregnating glass fiber with resin, the change in the film thickness of the surface layer causes
It is possible to bring out the effect that it looks as if a handle is attached, and with this configuration, it is possible to secure stable productivity at low cost.
