Description

[Detailed description of the invention] The present invention relates to a method for moisture-proofing, rot-proofing, and insect-proofing a house.

Moisture-proofing, rot-proofing, and insect-proofing treatments are important for buildings, especially wooden houses.

If a building is damaged by termites or the like, it may even be destroyed, and wood-rotting fungi that rot the wood are also harmful to the building.

In particular, when wood-decaying fungi grow in parts that give strength to a building, such as the foundation that makes up the underfloor area, the building is exposed to a very dangerous condition.

Wood-decaying fungi and termites generally prefer humid places,
Under the floor is also a good place for these house pests to live. Water evaporates from the soil surface below the bed.

Conventionally, polyethylene sheets have been laid down as a countermeasure against moisture under floors, and sheets called Alicon sheets have been laid down for the purpose of moisture proofing, rot prevention, and termite control.

However, these methods of laying sheets require complicated work, make it difficult to work in narrow spaces, and require cutting the sheets to fit the irregular shape of the foundation.
Even so, there was a problem that a complete moisture-proofing effect could not be obtained because there was a gap between the button and the foundation.

On the other hand, there is a method of spraying a synthetic resin containing a chemical into the soil beneath the bed, but in this method, the synthetic resin emulsion (chemical solution) permeates into the soil before it forms a dry film on the soil surface, resulting in a moisture-proofing effect. The problem is that it requires a large amount of chemical solution. Historically, soil surfaces have not necessarily been flat, but have been uneven. With this method, if the soil surface is uneven, for example, the chemical solution will spread to the concave areas but not to the white areas, so even if the chemical solution is sprayed, it will not be possible to form a homogeneous film on the soil surface. Therefore, the moisture-proofing and antiseptic effects cannot be fully exhibited.

The present invention provides a moisture-proof, TTX-proof, and insect-proof treatment method aimed at eliminating the drawbacks of the prior art. A moisture-proofing method for a house, characterized in that a treatment liquid containing a chemical agent and a foaming agent is foamed in advance and sprayed, or sprayed while foaming, or foamed after spraying, and then dried to form a dry film. The method of the present invention is an excellent moisture-proofing, rot-preservative, and insect-proofing method as follows. That is, (1) in the present invention, when the treatment liquid is sprayed after being foamed in advance or when it is sprayed after being encapsulated, the foam of the treatment liquid propagates one after another on the subbed soil surface (therefore, If a synthetic resin emulsion is simply used, the liquid permeates into the soil and requires a large amount of chemical solution, but according to the present invention, permeation of the chemical liquid into the soil is prevented, and a small amount is required by increasing the volume by scraping. The foaming process allows the bubbles of the treatment solution to propagate over the soil surface one after another, covering any uneven surfaces on the soil surface and forming a dry film with high moisture-proofing effects1. This makes it easy to work even in areas that are normally difficult to work in, such as on the subfloor soil surface.

Spraying the chemical solution and foaming can be easily done by spraying, etc. even after the base is placed on the foundation. This method is also effective for houses that have already been constructed. Normally, when spraying a chemical solution, the chemical solution scatters around and often exposes the worker to the chemical solution, but according to the present invention, the treatment solution easily travels over the soil surface due to the action of bubbles. Since it can be left alone, the chemical solution will not be scattered around, the workers will hardly be exposed to the chemical solution, and there is no need for people to crawl under the floor.

(11) In the method of foaming the treatment liquid after spraying, the above (+
) Spreading crushed soil in advance or spreading it while foaming is different, but the conditions at the time of spreading are different.
The effect of foaming and forming a film on the sag surface is the same as the effect of the film breaking, and it can be selected as appropriate depending on the situation of the place where it is to be sprayed. That is, according to this method, the chemical solution remains soaked into the soil immediately after being sprayed, but the chemical solution comes out to the soil surface due to foaming, thereby making it possible to sufficiently cover uneven surfaces.

(II+) The present invention uses a synthetic T-J fat emulsion with high moisture resistance, the treatment liquid spreads over the entire soil surface by foaming, and a thick film is formed by the two bubbles. , At this time, the skin is highly moisture resistant and has a high moisture resistance.
By using a vinyl acetate emulsion that is easy to form, the film formed after spraying (foaming) is thick and uniformly spread over the entire surface, and has a moisture-proofing effect that suppresses moisture evaporation from the soil. There is. Of course, preservatives,
Since it contains an insect repellent, it has a high antiseptic and insect repellent effect.

(1v) The cured film formed by the method of the present invention has a heat-insulating effect due to the inclusion of air bubbles due to foaming and the formation of a sufficient film thickness, and can simultaneously exhibit heat-insulating effects, moisture-proofing, rot-proofing, and insect-proofing effects. So the advantages are significant.

Next, a supplementary explanation will be given regarding the configuration of the present invention.

Synthetic resin emulsion and resin “CI” used in the present invention
Various synthetic resin emulsions such as L-vinyl acetate emulsion, ethylene-vinyl acetate emulsion, and acrylic emulsion can be used alone or in combination of two or more. Among them, vinyl acetate emulsion is preferred. As mentioned above, the film of vinyl acetate emulsion is highly moisture-proof, and the film is
It is also easy to model.

As the wood preservative and insect repellent used in the present invention, various known rot and insect repellents can be used. Examples include chlordane (emulsions, solubilizers, oil agents), mixtures of chlordane and tributyltin compounds, insect repellents such as boron compounds and fluorine compounds, type 1, type 2, and type 3 specified in JIS K 1550. Seed phenols, inorganic compound water preservatives, No. 1 specified in JIS K 1554,
No. 2, chromium, copper, arsenic compound wood preservative, JIS
There are creosote oils specified in K 2439. These drugs can be dissolved in water or the like, or used as they are in the form of liquid preparations.

Examples of the blowing agent used in the present invention include surfactants having foaming properties and isocyanate compounds such as methylene diinocyanate (MDI). It is preferable to use an anionic surfactant as the former surfactant.

Examples of surfactants that can be used include fatty acid esters, alkyl sulfate esters, alkylaryl sulfonic acid groups such as alkyl benzene sulfonates, and alkyl sulfonates.

If desired, an inorganic filler such as titanium oxide, clay, or carbonaceous material may be mixed into the treatment liquid of the present invention. By adding this inorganic filler to h5, a hard dry film (curing degree IW<) can be produced. It is also possible to add waxes such as paraffin wax in the form of an emulsion. Addition of this wax further improves moisture resistance. Furthermore, silicone 471 fat may be added for the purpose of improving moisture resistance, or Poval (PVA) may be added as a thickener. In addition, in the present invention, various additives such as substances that promote curing may be added to the processing liquid. In order to further improve workability, it is desirable to add water.

The amount of each component is determined based on the condition of the subbed soil surface and the amount of cB released.
Although it is difficult to say exactly because it depends on the type of agent, etc., for example, when using a surfactant (foaming agent) as a blowing agent, it is 1 to 5 Mff per 100 parts by weight of vinyl acetate emulsion.
11 parts, preferably 1 to 3 parts, and when using an incyanate compound, 1 to 5 M parts may be blended.

Next, examples of the present invention will be shown.

Example 1 An anticide and a foaming agent were prepared by diluting an emulsion of vinyl acetate (vinyl acetate (non-volatile content: 45%, viscosity: 400,000 cPsO) and chlordane (I): 8% with water to a ratio of 14-R (14-R ratio).
A treatment solution consisting of Emar AD-25, Kao Atlas (trade name) was sprayed onto the subbed soil surface while foaming it using a spray gun, and a solution that had been foamed in advance by stirring with a stirrer was sprayed. After spraying and air drying, a cured film of vinyl acetate having a thickness of 11 was obtained from a 500μ film.
