Abstract

PURPOSE:To provide a mildewcide for the interior material constituting the wall of a building, by using 4-chloro-3,5-xylenol as an active agent for preventing the deterioration. CONSTITUTION:The objective mildewcidal agent contains 4-chloro-3,5-xylenol which is effective against the deteriorating fungi such as those belonging to Penicillium genus, Alternaria genus, Pullularia genus, etc. The agent is applied without dilution or in the form of emulsifiable concentrate, wettable powder, etc., by mixing in or adsorbing to the interior material or the adhesive of the wall. The growing of mold is suppressed and the deterioration of the wall material, etc. can be prevented by the addition of the compound.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides 4-chloro1-
45-Relating to a fungicide for interior materials constituting the walls of buildings, which contains silenol as an active ingredient.

Construction of the building has recently been completed and Ryogo Kawanouchi JIK
Occurrence of moldy steel was observed, and there was an increase in the number of mid-point straight lines on the inner ring. 41K The occurrence of mold is caused by wallpaper and glue.
EIX pieces are often pasted on wall walls, which are finished to look like workers. This structure is rarely observed in the mortar construction method, but in the gypsum direct bond construction method, which is commonly called the σ-method or the Petane construction method among construction professionals, it is possible to replace plasterboard with PC board, concrete, or plastic. Adhesive (for example, product name GL Bond, Snow Bond) is added to the base wall such as concrete boards or MLC boards, mixed with K water, and then applied to the base wall, and then plasterboard etc. are applied on top of it. Directly linked construction method O is particularly frequently recognized after construction is completed. This construction method is very easy to use, the construction can be completed in a short period of time, and the installation method creates a layer of air between the plasterboard and the base wall. Since the layer has the advantage of creating very favorable conditions for heat insulation and electrical protection, the ζO construction method is widely used in constructions such as indoor buildings. . However, since no measures have been taken to prevent the growth of mold in buildings built using these construction methods, mold is likely to grow, and when exposed to high temperature and high temperature conditions such as those in the Sake Revolution, it is difficult to finish the construction with great care. *
Vao*wm has mold and honey.

There are many cases where it is necessary to repair the product until it becomes discolored. There is a strong need for measures to prevent the re-sharpening of the Marunouchi ring construction, and to prevent rounding and molding, which cause great damage in both labor and economic terms.

Honjitsu et al. studied the zero mold generation mechanism in this field and came to the following conclusion! Reach 1111.

That is, base 11KII adhesive Cf4jLd, mEOc
Apply kX, GND (largely Snokubond) with a fist of a dumpling, and apply a layer of gypsum on top of it to prevent moisture o'* and volatilization, which are present in large amounts in the adhesive. The starch Stt9, which is present in the adhesive when spinning, causes mold to form on natural materials such as funori. This is a concrete phenomenon that occurs inside 11 and cannot occur in llI*, so it has nothing to do with direct **-, and mold growth is not a problem at this point. Next, the moisture that was severely prevented from evaporating and volatilizing by the plasterboard eventually migrates to the wax plasterboard.
Since cloth, vinyl, etc. are pasted on, the evaporation and volatilization of moisture is also hindered, resulting in moisture remaining between the gypsum board and the wallpaper. Furthermore, adhesives containing natural substances as described above exist between the plasterboard and the wallpaper to hold the wallpaper in place, and as this migrates and stagnates, it can absorb moisture and cause mold and mildew. It is a good source of nutrients during the outbreak. In this way, when the conditions for mold generation are satisfied, mold will rapidly grow and grow, causing the surface of the wallpaper to grow.
It comes to appear in t. In this way, internal iimo deterioration occurs J)I! As a result, I ended up having to make some minor corrections.

The present inventors isolated and fixed nine molds that occurred in this area, and found that typical deteriorating molds include Peninrium spp.
Please note that they are Alternaria genus and Pluralia genus Son. Based on this knowledge, the present inventors believe that if the agent is effective against these deteriorated soaps and is adsorbed at a predetermined concentration before mixing with the interior materials and adhesives of the former wall, JIIK will prevent mold.
We believe that O generation can be suppressed and deterioration can be prevented, and various studies have been carried out. As a result, it was discovered that 4-chloro-45-xylenol is extremely effective as a deterioration inhibitor, leading to the completion of the present invention. These compounds can be used in the form of pharmaceutical preparations, such as a raw material or an emulsion.

Some examples of excipients are listed below.

Formulation Example 1 (Emulsion) 4-Cool-3,5-xylenol 5s (parts by weight are shown, the same applies hereinafter), 85 parts of Shito in dimethylsulfonate, and 11 parts of Tsurupo 5-2959C, Kagaku Kogyo Co., Ltd. Emulsifier o
ii & 4) Mix and dissolve to make an emulsion.

This product can be used as is or diluted with water.

Formulation Example 2 (Irrigation agent) 40 parts of 4-cool-45-xylenol, 8 parts of lauryl sulfate, and 42 parts of clay were uniformly mixed and pulverized to prepare an irrigation agent. This product is used after being diluted with water.

Nine test examples using the fungicide according to the present invention are shown below.

Test Example 1 GL Bond (trade name of adhesive manufactured by Yoshino Gypsum Co., Ltd.) 25
Add 14 parts of a medicinal solution containing α5-4-chloro4-'5,5-xylenol (diluted solution of water conservancy of Formulation Example 2) to the mixture and mix well. This crosstalk makes nine ()L pounds approximately 60,021)

"Kllgt-16111 vinyl/polyvinyl alcohol co-pasted with Jigura's adhesive and finished. After that 6
In the 0-day test, no mold O was observed, but in the no-chemical additive test, 1 mold appeared and deteriorated after 14 days.

This test example was conducted during the rainy season, when molds are most prevalent.

Test Example 2 Sunoku〆nd (trade name of adhesive manufactured by Nitto Gypsum Co., Ltd.)
251B, add 14 parts of the system i1 (diluted solution of emulsion of Example 10) of 4-chloro to 5-xylene-enzyme 0.6-, mix well, and apply this to the concrete of the base wall. roar 1
Apply blood in the form of dumplings at a ratio of 4 pieces, and immediately place 4 pieces on the plasterboard.
Starch containing 0.3 d of xylenol
I finished it by pasting 11 pieces of paper.

After that, no outbreak of mold was observed for more than 90 days, but after 7 days of pasting wallpaper in the drug-free area, mold and mildew actually occurred at the application site. ,1
After 4 days, the entire wallpaper was covered with mold and deteriorated.

This test example was conducted during the rainy season when mold growth is most active.
*It is a thing.

Test Example 3: Add 14 parts to 25 parts of this commercially available gypsum board adhesive, carefully mark it with ink, stick round pieces on a concrete wall in the form of 1-14 pieces, and paste the gypsum board on top of it for 4 hours. I left it alone to adhere. Two days later, 4-Cool-3,
Acrylic transparent wood jI containing 5-Kijileno Lumi and SS
I applied IIk and left it for 2 days.

On top of this, wallpaper was pasted with a vinyl acetate/polyvinyl alcohol copolymer adhesive, and no mold growth was observed after 60 days on the ridge, but no chemical-added area was found to have mold after 14 days. Mold was observed on the entire surface of the wallpaper.

This test example was carried out during the rainy season when mold grows.゛Patent sponsor: Hokuko Chemical Industry Co., Ltd.
