Description

The present invention relates to a film-forming agent composition for cleaning, a method for cleaning the floor surface on which sanitary equipment is installed, a method for preventing contamination of the floor surface on which sanitary equipment is installed, and a method for deodorizing the environment where sanitary equipment is installed.

Sanitary equipment such as washbasins, toilet bowls, bathtubs, kitchen sinks, etc., which are sanitary appliances for washbasins, toilets, or bathrooms, are partially or wholly located on the floor. Usually, a part of the sanitary equipment or a pipe connected to the sanitary equipment is located in the through hole of the floor or wall.
Cleaning of the sanitary equipment main body is easy, but dust, dirt, water, etc. tend to collect on the floor surface at the peripheral edge of the sanitary equipment main body, which tends to be unsanitary. For example, when a toilet bowl such as a Western-style toilet bowl or a Japanese-style toilet bowl is placed on the floor of a toilet, a gap is generated at the boundary between the floor plate and the toilet bowl. Urine and water scattered on the outer surface of the toilet bowl and the floor surface when using the toilet bowl enter the gaps and cause stains and foul odors on the floor surface.
In addition, to clean the dirt accumulated in the gap, a method of scraping it out by combining a tool such as a brush or a rag with water is adopted, but there is a problem that the tool does not go all the way into the gap and the dirt cannot be completely removed. .. In addition, new cleaning products and cleaning methods are required from the viewpoint of physical burden during cleaning.

To solve these problems, a moisture-curable resin composition containing two specific polymers in a specific ratio has been proposed (Patent Document 1). According to the invention of Patent Document 1, it is possible to clean the surroundings of the sanitary equipment by preventing the surroundings of the sanitary equipment from becoming dirty and peeling the cured resin from the adhered portion after the stain is made.
Further, as a composition for purifying by forming a film and removing the formed film, a film-forming agent composition for cleaning containing a specific polymer, water, and a specific organic solvent in a specific mass ratio. A product has been proposed (Patent Document 2). According to the invention of Patent Document 2, the sash rail and the like can be easily and easily cleaned.

International Publication No. 2016/060112 Japanese Unexamined Patent Publication No. 2018-2828

However, in the invention of Patent Document 1, (a) the composition does not spread to the depth of the gap, (b) it is necessary to clean the surroundings of the sanitary equipment before using the composition, and the work is complicated. C) The composition has a problem that it cannot be used after a lapse of time after opening because it starts to cure once it comes into contact with air. The invention of Patent Document 2 has a problem that when it is applied to a gap between a sanitary equipment and a floor, the composition falls without staying on the opening surface of the gap, and the gap cannot be covered with a film. In particular, when the coating is applied to a gap opened in the horizontal direction, the composition does not penetrate into the gap and falls downward. Therefore, it is insufficient to close the gap and remove the dirt in the gap.
Therefore, an object of the present invention is a film-forming agent composition for cleaning, which can easily clean the inside of gaps between articles and prevent contamination of the gaps between articles and their surroundings.

(how to use)
A cleaning method, an antifouling method, and a deodorizing method using the film-forming agent of the present invention will be described.
<Cleaning method>
In the cleaning method of the present invention, a film-forming agent is applied to a cleaning target, the film-forming agent is dried to form a film (film forming step), and then the film is peeled off from the cleaning target (a film forming step). Peeling process).
Here, "cleaning" refers to a process of removing dirt existing in the object to be cleaned. Dirt may broadly refer to substances other than those to be cleaned, but the main stains are dust, dirt, etc., and those that have lost moisture after they have adhered with moisture. The cleaning treatment capacity broadly refers to the ability to remove stains, but mainly efficiency (amount that can reduce the substances of stains on the surface per hour), especially one cleaning treatment operation (in the present invention, one coating). It refers to how much dirt can be removed from the surface to be cleaned by the operation of forming and removing.

The object to be cleaned includes all places in the sanitary equipment installation environment such as a washroom, a toilet, a bathroom or a kitchen. In particular, the film-forming agent of the present invention can be suitably applied to the gap between the sanitary equipment and the floor. The material of the sanitary equipment is not particularly limited, and examples thereof include ceramics, metal, plastic, and glass. The material of the floor is not particularly limited, and examples thereof include ceramics, metal, plastic, glass, concrete, and wood.

Hereinafter, a method of cleaning the floor surface on which sanitary equipment is installed will be described as an example.
In the film forming step, a film forming agent is applied to the object to be cleaned. The object to be cleaned in this example is the floor surface on which sanitary equipment is installed (hereinafter, may be simply referred to as "floor surface"). The object to be cleaned may be any of the floor surfaces, but an area including a gap between the sanitary equipment and the floor on which the sanitary equipment is installed is preferable.
The width of the gap to be coated is, for example, preferably 0.01 to 5 mm, more preferably 0.1 to 3.0 mm. When the width of the gap is at least the above lower limit value, the film forming agent can penetrate into the gap and the dirt in the gap can be removed more satisfactorily. When the width of the gap is not more than the above upper limit value, the film formed by the film forming agent can more reliably cover the opening of the gap.
A film-forming agent is applied to the area including the gap between the sanitary equipment and the floor (gap-containing area). At this time, since the film-forming agent of the present invention has appropriate fluidity and retention, the film-forming agent penetrates into the gap and the opening of the gap is covered with the film-forming agent.
The method for applying the film-forming agent is not particularly limited, and examples thereof include a method of applying while pouring from a nozzle of a container, a method of applying with a coating tool such as a brush or a brush, and a method of applying by spraying with an aerosol spray or the like.
The amount of the film-forming agent applied is not particularly limited, and is, for example, 30 to 300 mg / cm ² . The amount of the film forming agent applied is preferably 0.1 to 0.3 g / cm with respect to the length of the boundary between the sanitary equipment and the floor.
A film is formed by the film-forming agent in a state where the film-forming agent is applied to the gap-containing region. The film is a film having a thickness of about 0.05 to 10 mm as a guide in the formed state (described later, in a state where the fluidity is lost). The film is formed by making the film-forming agent a solid (a state having no fluidity). In the present invention, the film is formed by drying the film-forming agent. Here, drying is to remove a part or all of a solvent such as water.
As a guideline, the degree of drying, that is, the degree of decrease in the water content of the film-forming agent may be a condition in which the film-forming agent becomes a solid.
When drying, natural drying, that is, a film-forming agent may be left to evaporate water naturally from the surface until a film is formed. Further, a means for applying wind to the film forming agent with a dryer, a fan, a ventilation fan or the like may be used in combination. After applying the film-forming agent, water-absorbing powder may be sprinkled on the applied surface to remove water from the film-forming agent.

At the stage of applying the film forming agent to the object to be cleaned, the dirt existing in the object to be cleaned is taken in from the object to be cleaned to the side of the film forming agent, so that the dirt is removed from the object to be cleaned. Further, even in the process of forming a film, for example, the process of leaving the film-forming agent to dry, dirt is removed from the object to be cleaned (the above is the film-forming step).

In the peeling step, the film formed on the object to be cleaned is peeled off and removed. When peeling off the film, the film of the present invention can be peeled off very easily by pinching the end with a finger. Further, for example, an operation of peeling the film from the object to be cleaned may be used in combination with a tool having a sharp tip such as a spatula or a bamboo skewer. Alternatively, when a paper or plastic plate to be a handle is installed to form a film, the handle may be integrated with the film to pinch the handle and peel off the film. If the film is hard and difficult to peel off, it may be peeled off using a tool. When the film is removed from the object to be cleaned in this way, the dirt existing in the object to be cleaned is removed together with the film (the above is the peeling step). The period from the application of the film forming agent to the peeling of the film is preferably, for example, 12 hours or more, more preferably 24 hours or more in an environment of 25 ° C. and a humidity of 50% RH. The upper limit of the period from the application of the film forming agent to the peeling of the film is not particularly limited, and may be peeled off after one month or one year, for example.

According to the above-mentioned method for cleaning the floor surface on which sanitary equipment is installed, the film-forming agent enters the gap and forms a film that covers the opening of the gap. Therefore, dirt from the outside does not adhere to the portion covered by the formed film (for example, a gap), and the dirt inside the gap can be easily removed by easily removing the film.

<Anti-fouling method>
The antifouling method (contamination prevention method) of the present invention includes applying a film-forming agent to an antifouling object and drying the film-forming agent to form a film (film forming step). In the antifouling method of the present invention, the film may be peeled from the antifouling target after the film forming step (peeling step).

Here, "antifouling" is a process for preventing dirt from adhering to the antifouling object.
The antifouling target is the same as the above-mentioned cleaning target.

Hereinafter, an antifouling method for the floor surface on which sanitary equipment is installed will be described as an example.
In the film forming step, a film forming agent is applied to the antifouling object. The film forming step in the antifouling method is the same as the film forming step in the cleaning method.
When a film is formed in the film forming step, dirt does not adhere to the portion covered by the film from the outside, and dirt adheres to the film. In this example, since the opening of the gap is covered with a film, it is possible to prevent dirt from entering the gap.

After forming a film and after an arbitrary period has elapsed, the film can be peeled off and removed (removal step) to remove stains adhering to the film. After that, by repeating the film forming step and the peeling step in this order, contamination of the antifouling target can be prevented.

<Deodorization method>
The deodorizing method of the present invention includes applying a film forming agent to a construction target and drying the film forming agent to form a film (film forming step). In the deodorizing method of the present invention, the film may be peeled from the construction target after the film forming step (peeling step).

Here, "deodorant" refers to a process of preventing the accumulation of dirt on the construction target or the deterioration of the dirt existing on the construction target to give off an offensive odor.
The construction target is the same as the above-mentioned cleaning target.
The space to be deodorized is the environment where sanitary equipment is installed. That is, the object to be deodorized is a washroom, a toilet, a bath, a kitchen, or the like.

Hereinafter, a deodorizing method for the sanitary equipment installation environment will be described as an example.
In the film forming step, a film forming agent is applied to the construction target. The film forming step in the deodorizing method is the same as the film forming step in the cleaning method.
When a film is formed in the film forming step, dirt does not adhere to the portion covered by the film from the outside, and dirt adheres to the film. In this example, since the opening of the gap is covered with a film, it is possible to prevent dirt from entering the gap. Therefore, the dirt does not remain in the gap for a long period of time, and the generation of odor due to the dirt can be prevented.

After forming a film and after an arbitrary period has elapsed, the film can be peeled off and removed (removal step) to remove stains adhering to the film. After that, by repeating the film forming step and the peeling step in this order, it is possible to prevent the generation of an offensive odor in the sanitary equipment installation environment.
The film-forming agent used in the deodorizing method preferably contains at least one of a deodorant, a disinfectant, and an antibacterial agent. When the film forming agent contains a deodorant, a sterilizing agent or an antibacterial agent, the deodorizing effect can be further improved.

Hereinafter, the present invention will be described in detail with reference to examples, but the present invention is not limited to the following description.
