Description

[Detailed explanation of the idea] The present invention relates to improvements in plastic bathtubs.

When manufacturing FRP (fiber-reinforced plastic) bathtubs, which are typical plastic bathtubs, using the hand lay-up method, spray-up method, or pine die method, patterned paper is embedded directly under the transparent gel coat layer to decorate the inner surface of the bathtub. There is.

Conventionally, various proposals have been made in order to give a three-dimensional effect to the pattern of the patterned paper, but this inevitably complicates the laminated structure of FRP, making it difficult to manufacture the bathtub.

By the way, when a pattern is attached to a glass fiber woven fabric or non-woven fabric, and this woven fabric or non-woven fabric is impregnated with a transparent polyester resin and cured, the light color of the pattern indicates the cooperation between the optical properties of the glass fiber and the polyester resin. As a result, it becomes transparent or translucent.

The present invention attempts to utilize the above characteristics of patterned paper for the interior decoration of FRP bathtubs.

That is, in the plastic bathtub according to the present invention, a pattern layer made of a patterned glass fiber woven fabric or non-woven fabric impregnated with polyester resin is provided on the inner surface of a colored FRP bathtub base, and a polyester resin coating layer is provided on the pattern layer. This configuration is characterized by the provision of.

The present invention will be explained below with reference to the drawings.

In the figure, 1 is a colored FRP bathtub base,
Molded from laminated glass mat impregnated with colored polyester resin.

Titanium oxide, cobalt oxide, etc. can be used as a coloring agent for the polyester resin.

2 is a pattern layer formed by impregnating a glass fiber woven fabric or non-woven fabric with a pattern by a gravure method, a transfer method, etc. with a transparent polyester resin.

3 is a coating layer made of transparent polyester resin.

In the pattern layer 2, the light-colored part of the pattern is transparent or semi-transparent due to impregnation with the transparent polyester resin, and light does not pass through this part to the bathtub base 1. As a result of this light being reflected, the pattern becomes rich in three-dimensionality.

The appearance of the inside of the bathtub is made by combining the pattern of the pattern paper 2 and the color of the bathtub base 1, and the image of its appearance is based on FR.
It can be changed depending on the type of coloring agent mixed into the polyester resin of the P bathtub base 1.

As mentioned above, the plastic bathtub according to the present invention focuses on the fact that if a patterned glass fiber woven fabric or non-woven fabric is impregnated with polyester resin, the lighter colored part of the pattern becomes translucent or transparent. was used to decorate the inside of a plastic bathtub to create a three-dimensional decorative pattern.

Therefore, to make the pattern three-dimensional, it is only necessary to color the bathtub base, the laminated structure is simple, and the bathtub can be easily formed.

[Brief explanation of the drawing]

The drawing is an explanatory diagram showing a plastic bathtub according to the present invention. In the figure, 1 is a bathtub base, 2 is a pattern layer, and 3 is a coat layer.
