DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a wood preservative used for preserving wood and controlling insects.

[0002]

2. Description of the Related Art Conventionally, wood used for civil engineering materials such as houses and buildings and general industrial materials such as furniture is protected from decay, mold, insect pests, and sunburn. For this purpose, treatment with wood preservatives has been performed.

[0003]

However, when wood is treated with a wood preservative, the surface of the wood is colored due to a high concealing rate during the treatment, and the wood has an inherent appearance such as color and texture. May occur. In particular, when wood such as white wood is treated with a wood preservative, the wood grain of the white wood is hidden by the wood preservative, and it is difficult to maintain a design that makes full use of the texture of the wood.

[0004] Even when treated with a wood preservative, the surface of the wood is gradually burned by long-term sunlight irradiation, and at the same time, a wood preservative / antifungal agent or wood which is an active ingredient of the wood preservative is used. The insect repellent may gradually decompose, causing wood decay and degradation by pests. Therefore, an object of the present invention is to maintain the state of utilizing the appearance and texture of the wood's inherent color, texture, etc., and to maintain the aesthetic appearance of the wood surface for a long period of time while effectively preventing deterioration by sunlight and the like. To provide a wood preservative that can be used.

Test Example 1) Preparation of Test Plate The wood preservatives obtained in the above Examples 1 to 10 and Comparative Examples 1 to 3 were mixed with cedar boards (straight grain) (length, 150 mm, width 70 mm,
0.5 g of a brush (polyester brush No. 1) was applied to a thickness of 10 mm) and dried at room temperature for 24 hours, and then 0.5 g of the same was applied and dried at room temperature for 7 days. 2) Evaluation The test plates prepared as described above were evaluated for the initial coloring degree, the weather resistance after a 6-month outdoor exposure test, the residual rate of the wood preservative / antifungal agent, and the occurrence of mold. 2-1 Initial coloring degree For each of the cedar boards before application of the wood preservative, L,
The a and b values were measured using a color difference meter (Σ90 type color difference meter manufactured by Nippon Denshoku Industries Co., Ltd.), and the L, a, and b values were measured again after application of the wood preservative, and before and after the measurement. Color difference (ΔE
Value) was calculated, and this was used as the initial coloring degree. 2-2 Outdoor exposure test The above-mentioned test plate was subjected to a 6-month outdoor exposure test using an exposure test stand inclined at 30 degrees facing the south side. 2-2-1 Weather resistance The L, a, b values before and after the outdoor exposure test were measured, and the color difference (Δ
E value) was calculated. 2-2-2 Residual rate of wood preservative / antifungal agent The center of the test plate after the outdoor exposure test was cut into approximately 30 mm squares, and a flake having a depth of 3 mm from the surface was prepared using a microtome. The wood preservative / antifungal agent was extracted using an acetonitrile solvent, and the residual ratio of the wood preservative / antifungal agent was determined by liquid chromatography. 2-2-3 Mold generation The presence or absence of mold generated on the test plate after the outdoor exposure test was visually determined.

The evaluation of visual judgment was as follows. A: No mold was observed by visual observation. ：: Mold was observed, although only a small part. Δ: Mold generation is partially observed. ×: Mold is observed on the entire surface of the test plate.

The results are summarized in Table 1.

[0043]

[Table 1]

From Table 1, it can be seen that the examples show better results than the comparative examples. Further, among the examples, a wood preservative / fungicide of Example 1 in which a triazole compound and a sulfamide compound were used in combination.
And it turns out that Examples 5-10 have prevented mold generation effectively.
