Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat sheet, a toilet seat bottom plate, a toilet lid, and a body case, which are provided with a resin layer on the surface of a resin molded product having not only good anti-fouling properties such as water repellency but also antibacterial properties. By providing on the surface of at least one member of the constituent material of the exposed component of the toilet seat for local cleaning such as a cleaning nozzle,
The present invention relates to a toilet seat on which a low surface free energy layer lower than a base resin surface of a member is formed.

[0002]

2. Description of the Related Art Many exposed components of a toilet seat, such as a toilet seat sheet, a toilet seat bottom plate, a toilet lid, and a main body case, are in direct contact with the skin, and their hygiene is taken into consideration, and many devices have been put into practical use. Was. For example, when the heating toilet seat member has both antifouling property and antibacterial property, as described in JP-A-9-56642, the toilet seat and the like are made of a resin body in which a silicone resin is dispersed to lower the surface energy and to provide water repellency. The antifouling performance is improved, and antibacterial properties are imparted by dispersing an antibacterial agent.

[0003]

In order to impart anti-fouling properties such as water repellency to exposed components of a toilet seat such as a toilet seat sheet, a toilet seat bottom plate, a toilet lid, and a main body case, even if a silicone resin is added to a resin material. Since the silicone resin is dispersed on the surface of the resin component that requires anti-fouling properties such as water repellency, it is necessary to add a corresponding amount of silicone to obtain sufficient water repellency. If the amount of the silicone resin is excessively increased, physical properties such as mechanical strength and moldability deteriorate.

In addition, when an exposed component of a toilet seat such as a toilet seat sheet, a toilet seat bottom plate, a toilet lid, and a main body case is provided with antibacterial properties, even if an antibacterial agent is added to the resin material, the surface of the resin component is not required to have an antibacterial effect. Since the antimicrobial agent is also dispersed, it is necessary to add a corresponding amount of the antimicrobial agent to obtain sufficient antimicrobial performance. If the amount of the antibacterial agent is excessively increased, heat resistance and the like deteriorate.

[0005] Further, when a pattern or the like is applied to an exposed component of a toilet seat such as a toilet seat sheet, a toilet seat bottom plate, a toilet lid, and a main body case,
Covering the surface of the resin component with the design material is a factor that hinders the antifouling and antibacterial properties of the resin component.

The present invention solves the above-mentioned drawbacks and provides a film-shaped or sheet-shaped resin layer having not only antifouling properties such as water repellency but also antibacterial properties on the surface of a resin molded product.
It is possible to have good antifouling properties and antibacterial properties without lowering the mechanical strength etc. of the resin molded product, and furthermore, the outermost surface of the resin layer is a transparent clear layer that can be colored and a pattern ink layer on the underlayer It is an object of the present invention to provide an exposed component of a toilet seat such as a toilet seat sheet, a toilet seat bottom plate, a toilet lid, and a main body case, which has antifouling properties, antibacterial properties, and a picture pattern.

[0007]

In order to achieve the above-mentioned object, a toilet seat sheet according to claim 1 is provided.
A film- or sheet-like resin layer is provided on the surface of the exposed component of the toilet seat for local cleaning such as a toilet seat bottom plate, a toilet lid, a main body case, and a cleaning nozzle, and a low surface free energy layer lower than the base resin surface of the member. And

[0008] The method for producing the resin layer of the present invention on the surface of an exposed component of a local cleaning toilet seat such as a toilet seat sheet, a toilet seat bottom plate, a toilet lid, a main body case, and a cleaning nozzle includes the following steps. After being placed in the mold and closing the mold, the molten resin is injected into the mold, and the resin is solidified to bond the resin layer to the resin molded product.

In this manner, the toilet seat of the present invention can be provided with an antifouling property having a low surface free energy on the surface of the molded article, a high surface hardness and a low scratch resistance.

A three-layered film-like or sheet-like resin layer has a structure in which a transparent transparent layer which can be colored and a pattern ink layer and an adhesive layer are sequentially formed on the transparent layer.

[0011] Alternatively, the film-shaped or sheet-shaped resin layer is formed into two layers, and a transparent clear layer which can be colored and a pattern ink layer are sequentially formed on the transparent layer.

[0012] Alternatively, the film-shaped or sheet-shaped resin layer is made into a single layer, and is formed of only a transparent transparent layer which can be colored.

Further, the clear layer contains a silicone resin.

The clear layer contains an antibacterial agent.

According to another aspect of the present invention, the low surface free energy layer is formed in the form of a film or sheet on at least one member of a toilet member such as a toilet seat sheet, a toilet seat bottom plate, a toilet lid, and a main body case. A resin-based polyolefin molded article as a base resin, wherein the film-shaped or sheet-shaped resin layer is a polypropylene-based thermoplastic resin film having a silicone resin layer formed on one side, and the silicone resin layer is an outermost layer. By laminating the surface by heat fusion, a low surface free energy layer is formed on the base resin surface, and a surface layer having antifouling properties is obtained, and the layer having antifouling properties with strong adhesion is peeled off. There is no.

In order to realize the above-mentioned strong adhesion, in claim 9, the polyolefin molded article as the base resin is made of a polypropylene resin. Thereby, strong adhesion is obtained because the material is the same as that of the film.

Further, in order to easily fuse the film to the polyolefin molded article as the base resin at the time of molding, the low-melting point is provided on the other side of the thermoplastic resin film having the silicone resin layer formed on one side. A resin layer was laminated.
This silicone resin layer was attached to a mold so as to be in contact with the mold surface, and polyolefin was supplied to perform film in-mold molding. As a result, a film having antifouling properties is laminated simultaneously with molding.

[0018] In this configuration, since the low surface free energy layer is formed on the surface, it is possible to provide an antifouling local cleaning toilet seat having a surface with a small adhesion of dried and solidified dirt.
