m, 40 mm long cedar or beech wood pieces, each 110
A test piece was obtained by applying ± 10 g / m ² . The test pieces were tested in accordance with the preservative efficacy test method of the Japan Wood Preservation Association Standard No. 1 (hereinafter referred to as the present method) described below.

(1) Weathering operation In the weathering operation, leaching and volatilization operations were alternately repeated 30 times. In the leaching operation, the same treatments were put together and immersed in static water at 25 ± 3 ° C. for 5 hours to leached out the leached components without making contact with each other. The volume ratio of water to test specimen is 10: 1
And replaced with fresh water every time the operation was repeated. In the volatilization operation, the test body after the leaching operation was lightly drained and immediately left in a circulating dryer at a temperature of 40 ± 2 ° C. for 19 hours to be volatilized. After the weathering operation was completed, the test specimen was dried at 60 ± 2 ° C. for 48 hours in a circulating drier and then left in a desiccator for about 30 minutes to measure its weight (W ₃ ) to 0.01 g.

(2) Antibacterial operation An antibacterial operation was performed on the test body after the weathering operation. The treated and untreated specimens were separately placed in a Teflon plate frame three times per culture bottle, sterilized, and then
Place the test bacterium (Ouenix mushroom or Kawatake mushroom) on the bacteria so that the surface of 0x5mm faces down, at a temperature of 26 ± 2 ° C,
We stayed at a relative humidity of 70% or more for 8 weeks. After 8 weeks, remove the test specimen, carefully remove mycelia and other deposits on the surface, air-dry for about 24 hours, dry at 60 ± 2 ° C for 48 hours in a circulating dryer, and for about 30 minutes After standing in a desiccator, its weight (W ₄ ) was measured to 0.01 g. The efficacy is represented by the weight loss rate calculated by the following equation, and the results are shown in Table 2. In addition, the old method used the following weathering operation, and also performed a test in the same manner as the above method. In addition, without the weather resistance operation, only the antibacterial operation was performed without performing the weather resistance operation.

(1 ') Weathering operation of old method In the weathering operation, the operation of leaching and volatilization was alternately repeated 10 times. In the leaching operation, the same treatments were put together and immersed in a still water of 25 ± 3 ° C. for 30 seconds in a desiccator further filled with water at the bottom for 4 hours so as not to come into contact with each other, thereby leaching out the leached portion. . The volume ratio of water to the specimen is 10: 1,
We replaced with fresh water every time the operation was repeated. In the volatilization operation, the test piece after the leaching operation was lightly drained and immediately left in a circulating dryer at a temperature of 40 ± 2 ° C. for 20 hours to be volatilized. After the weathering operation was completed, the test specimen was dried at 60 ± 2 ° C. for 48 hours in a circulating drier and then left in a desiccator for about 30 minutes to measure its weight (W ₃ ) to 0.01 g.

Test Example 4 As a preservative component, 3-bromo-2,3-diiodo-2-propenylethyl carbonate (A-1)
And p-chlorophenyl-3-iodopropargyl formal (A-2), and chlorpyrifos (B-4), phoxime (B-5) and octachlorodipropyl ether (B-3) as insect repellent components. As the ionic surfactant, L-77 (manufactured by Nippon Yunika Co., Ltd., side chain-modified silicon-based nonionic surfactant: viscosity 20 cst, surface tension 20 dyne / cm, HLB10: C-1) was used. SFT (manufactured by Nippon Emulsifier Co., Ltd., emulsifier: polyoxyethylene styryl phenyl ether and calcium dodecylbenzene sulfonate: D-
Using 1), emulsions having the components shown in Table 7 were prepared. A solution obtained by diluting this emulsion with water 20 times was 5 mm thick,
