ていた。[Prior art and its problems] Phoxim emulsion, which has been used as an anti-termite agent,
Phoxim stock solution is simply emulsified in water using an emulsifier, and this is used for concrete, white cement, joints, etc.
It was used by spraying it on wood, plywood, etc., or by injecting it under pressure.

に（Ｉ）で示す共役二重結合をもつ着色性物質が生成さ
れることによるものと推定されている。Here, the reason why phoxim emulsion turns yellow due to the action of sunlight or alkali is that the ester bond in the phoxim molecule is broken by the action of sunlight or alkali, producing a colored substance with conjugated double bonds. It is thought that this is due to this. For example, the discoloration of phoxim due to sunlight is caused by the cleavage of the ester bond in the phoxim molecule by sunlight, as shown in the reaction formula (1) below, resulting in the coloration caused by the conjugated double bond shown in (I) in the reaction formula. It is presumed that this is due to the production of substances.

［問題点を解決するための手段］
この発明は、上記のような問題を解決せんとしてなされ

Acetic acid, mercaptopropionic acid, etc., benzyl mercaptan containing a phenyl group in R, polyvalent mercaptan containing two or more mercapto groups, etc. can be used.

料が着色するのを抑制する作用を果たすと考えられる。[Function] As described above, when a mercapto compound is mixed with a phoxim emulsion, if an acidic compound such as mercaptoacetic acid or mercaptopropionic acid is used as the mercapto compound, based on the experimental knowledge of this inventor. For example, these mercapto-based compounds are added to the conjugated double bonds of coloring substances generated by the action of sunlight or alkali, changing the coloring substances to non-coloring substances, and causing materials such as concrete to become colored. It is thought that it has the effect of suppressing the

色性物質に変化すると考えられる。For example, in the case of the colored substance (I) shown in the reaction formula (1) above, a mercapto compound is added as shown in the reaction formula (2) below, resulting in a non-colored substance shown in the chemical formula (II). It is thought that it changes into a sexual substance.

は弱かった。(I) (n) In this way, in the case of mercapto-based compounds such as mercaptoacetic acid and mercaptopropionic acid, it is possible to eliminate colored substances produced by the action of sunlight or alkali without affecting the anti-termite performance of phoxim emulsion. Although phoxim has the effect of suppressing the discoloration of materials such as concrete by converting it into a non-coloring substance, the effect of suppressing the conversion of phoxim into a coloring substance itself was weak.

制する作用を持つためであると考えられる。On the other hand, when some mercapto compounds such as lauryl mercaptan are mixed into a phoxim emulsion, the phoxim emulsion not only does not turn yellow even when exposed to sunlight or alkali for a long time, but also There was no deterioration in the anti-termite performance of the emulsion. This is considered to be because, in the case of mercapto compounds such as lauryl mercaptan, phoxime has the effect of inhibiting itself from changing into a coloring substance.

いる。Further, in this invention, a mercapto compound is mixed with a phoxim stock solution emulsified in water, so that the phoxim emulsion and the mercapto compound are well mixed.

ラウリルメルカプタンを用いた場合を示す。[Example] Next, as a specific example of the present invention, mercaptoacetic acid was used as a mercapto compound in Example 1, and mercaptoacetic acid was used as a mercapto compound in Example 2.
In Example 3, β-mercaptopropionic acid was used, and in Example 3, n-mercaptopropionic acid was used.
The case using lauryl mercaptan is shown.

とを明らかにする。Based on these examples, when mercaptoacetic acid or mercaptopropionic acid is mixed with phoxim emulsion, the coloring of phoxim emulsion due to the action of sunlight or alkali can be prevented without affecting the anti-termite performance of phoxim emulsion. In addition, when lauryl mercaptan is mixed with phoxim emulsion, it is possible to prevent discoloration of phoxim emulsion due to the action of sunlight and alkali, and to effectively prevent discoloration of materials such as concrete. It will be clarified that it will be possible to suppress the deterioration of termite prevention performance etc.

この結果、メルカプト酢酸が１％加えられた試料Ａ１の
ものでは着色度が２０．１．５％加えられた試料Ａ２の
ものでは着色度が１０．２％加えられた試料Ａ３のもの

着色の程度が著しく低くなっていた。As described above, the phoxim emulsion mixed with mercaptoacetic acid had a significantly lower degree of coloring on white cement than the phoxim emulsion containing only the phoxim emulsion.
なお、メルカプト酢酸を用いた場合、非常に安く製造で

酸を加えた各試料のものとを比較した。Next, in the same manner as in Example 1, the standard sample and each sample to which β-mercaptopropionic acid was added were compared in terms of coloring due to sunlight.
この結果、ホキシム単独の標準試料の着色度を１００と
した場合、β−メルカプトプロピオン酸を１％加えたも
のでは着色度が３０．１．５％加えたものでは着色度が
１０．２％加えたものでは着色度が１０．３％加えたも
のでは着色度が５であった。As a result, when the degree of coloration of the standard sample of phoxim alone is 100, the degree of coloration increases by 10.2% when 1% β-mercaptopropionic acid is added, and 10.5% when 1% β-mercaptopropionic acid is added. The coloring degree was 5 when the coloring degree was 10.3%.

なお、このようにβ−メルカプトプロピオン酸を用いた
場合は、メルカプト酢酸の場合に比べては若干コストが
高くなるが、硫黄臭は非常に少なかった。In this way, when β-mercaptopropionic acid was added, as in the case of Example 1 above in which mercaptoacetic acid was added, the degree of coloring of the white cement was significantly lower than when using only phoxim emulsion. Ta. Note that when β-mercaptopropionic acid was used in this way, the cost was slightly higher than in the case of mercaptoacetic acid, but the sulfur odor was very low.
また、この実施例では、β−メルカプトブロピオン酸を
用いたが、α−メルカプトプロピオン酸を用いることも

- Lauryl mercaptan concentration of 1%, 2%, 3%, 5%
Four types of samples D1 to D4 were prepared.
そして、この実施例では、まずこれらの各試料を、日光

て、より一層有効に利用できるようになる。Furthermore, when a mercapto compound such as lauryl mercaptan is mixed into a phoxim emulsion, the lauryl mercaptan acts as a stabilizer that suppresses the transformation of phoxim into a coloring substance, and is protected against the effects of sunlight and alkali for a long time. Since it does not change color and its anti-termite performance does not deteriorate, it can be used even more effectively as an anti-termite agent added to materials such as concrete.
