(57) [Abstract] [Purpose] A unit bath waterproofing that is made of reinforced plastic with a composite artificial stone decorative panel on the floor surface, is lightweight, has excellent flatness, and expresses the deep texture of stone. Aim to get bread. [Structure] Artificial stone decorative panel 1 obtained by casting a resin composition in which crushed stone particles do not settle during molding and is transparent, is placed on the floor surface, and is a reinforced plastic made of glass fiber and unsaturated polyester resin. The layer 2 is integrally molded to form the unit bath waterproof pan 3.

[Industrial applications]

 The present invention relates to a waterproof pan for a unit bath.

[0002]

[Prior art]

 Traditionally, waterproof pans for bathrooms are produced by hot pressing a sheet molding compound (SMC) consisting of glass fiber and unsaturated polyester resin using a mold, or hand lay-up of glass fiber and unsaturated polyester resin. There were waterproof pans made of reinforced plastics that were molded by spraying up, or composite waterproof pans that were made by molding reinforced plastics with artificial stone decorative panels placed on the floor.

[0003]

[Problems to be solved by the device]

 Reinforced plastic waterproof pan made by SMC's thermo-compression molding, hand lay-up, and spray-up molding has excellent strength and waterproofness, but has complicated patterns and the depth of stone material. It was difficult to express the texture, and I could only get a simple appearance.

The waterproof pan integrally formed with the artificial stone decorative panel arranged on the floor surface is liable to warp due to the dimensional change of the artificial stone, making it difficult to maintain the flatness of the floor surface. . Moreover, aluminum hydroxide is often used as a filler in artificial stone decorative panels, making it difficult to express the deep and transparent feeling of natural stone.

The present invention is a unit bath waterproof pan that is made of reinforced plastic with a composite artificial stone decorative panel on the floor surface, is lightweight, has excellent flatness, and expresses the deep texture of stone. Aim to get.

[0006]

Means for Solving the Problems The present invention provides 10 to 50 parts by weight of a thermosetting resin having a viscosity of 0.1 to 3 pa · s at a temperature of 20 ° C. and 5 to 50 stone crushed particles having a particle diameter of 300 μm to 5 mm. An artificial stone decorative panel obtained by cast molding a resin texture composition consisting of 20 to 65 parts by weight of a silica powder filler having a weight part of 1 to 50 μm is a reinforced plastic made of glass fiber and unsaturated polyester resin. It is a unit bath waterproof pan that is characterized by being integrally molded with the floor to form the floor surface.

As the raw material resin for the artificial stone decorative panel of the present invention, a liquid thermosetting resin having a viscosity of 0.1 to 3 pa · s such as unsaturated melamine resin, unsaturated polyester resin, and methylmethacrylic resin is used. As the crushed stone particles, granules having a particle diameter of 300 μm to 5 mm obtained by further crushing small pieces of cold water stone, granite, marble and the like are used. As the filler, a silica powder filler having a particle size of 1 to 50 μm is used in order to impart transparency.

When these materials are mixed in the above mixing ratio, they are hardened while maintaining a uniform dispersion state. That is, since the crushed stone particles and the filler do not settle in the resin liquid, the materials are not biased and the degree of expansion and contraction of the panel does not become unbalanced.

The floor surface of the waterproof pan is formed by the artificial stone decorative panel by arranging the artificial stone decorative panel at a position which becomes the floor surface of a mold made of reinforced plastics that has been subjected to a mold release treatment. Using an unsaturated polyester resin containing a colorant and the like, it is molded by a method such as hand-up or spray-up, and an artificial stone decorative panel and a reinforced plastics layer are combined and integrated.

【Example】

 Example 1 An example of the present invention will be described below with reference to the drawings. 50 parts by weight of a polyester obtained by condensing isophthalic acid, phthalic anhydride, fumaric acid, and propylene glycol was dissolved in 50 parts by weight of styrene monomer to obtain a viscosity of 1 pa · S at a temperature of 20 ° C. 30 parts by weight of saturated polyester resin, particle size of 0. 10 parts by weight of cold water crushed granules of 5 to 1 mm, 20 parts of granulated crushed granules of particle diameter of 1 to 2 mm, and 40 parts of silica powder having an average particle diameter of 6 μm are uniformly mixed, and an artificial petrochemical decorative panel of 4 mm in thickness is formed There is.

This artificial stone decorative panel 1 is arranged in a molding die so as to be the floor surface of a unit bath, and is made of a chopped strand mat of glass fiber, an inorganic pigment, and an isophthalic acid-based unsaturated polyester resin containing titanium oxide on the back surface. The reinforced plastics layer 2 having a thickness of 3 mm is formed to form an integrated composite floor, and the unit bath and the waterproof pan 3 are configured.

[0012]

[Effect of device]

 By making the resin composition of the artificial stone decorative panel the component composition of the present invention, the crushed stone particles do not settle during molding and are cured in a uniformly dispersed state. Therefore, there is no partial difference in material composition within the same panel, and warpage or twisting due to the difference in shrinkage does not occur. Furthermore, the weight reduction can be achieved by the combination with the reinforced plastics.

Even when the reinforced plastics layer is combined, the flatness of the floor surface can be maintained and the drainage property is good. In addition, since silica powder is used as the filler in the artificial stone decorative panel, the transparency is not impaired, the crushed stone particles and the texture of the resin are utilized, and the deep appearance of natural stone is reproduced.
