Example 19
An antifoam composition 19 was obtained in the same manner as in Example 1 except that Mistrone Vapor (Sobue clay talc, average particle size 5 μm) was used instead of the nip seal L-250.
[0051]
Example 20
Antifoam composition 20 was obtained in the same manner as in Example 1 using Kao White (Kaolin clay manufactured by Shiraishi Kogyo Co., Ltd., average particle diameter: 2 μm) instead of the nip seal L-250.
[0052]
Example 21
An antifoam composition 21 was obtained in the same manner as in Example 1 using Escalon # 100 (Sankyo Flour Milling Calcium Carbonate, average particle size 5 μm) instead of the nip seal L-250.
[0053]
Examples 22-24
In Examples 1 to 3, defoaming agent compositions 22 to 24 were obtained in the same manner using 500 parts by mass of mineral oil having a kinematic viscosity of 20 cSt.
[0054]
Comparative Examples 1-4
Antifoam compositions 25-28 were obtained in the same manner as in Example 1 except that the silicone compounds 13-16 were used in place of the silicone compound 1.
[0055]
Comparative Example 5
In Example 1, 50 mass parts of a mineral oil having a kinematic viscosity of 20 cSt was used to make an antifoaming agent in the same manner. However, the antifoaming agent composition was not solidified.

Table 1 shows the defoaming evaluation results.
[0057]
[Defoaming evaluation method 1]
After adding 0.5 parts by mass of an antifoaming agent to 100 parts by mass of a household water-based paint, the mixture was stirred with a homogenizer at 2000 rpm for 2 minutes, and then the specific gravity was measured with a specific gravity cup. The larger the specific gravity value, the better the defoaming performance. Moreover, after measuring the specific gravity cup, it applied to the slate plate with a roller, and the speed of disappearance of the foam was measured. The smaller the number, the better the defoaming performance. The measured household paint was put into a sealed container and stored at 50 ° C. for 1 week, and then the same test was conducted to evaluate the continuous defoaming property.
[0058]
[Defoaming evaluation method 2]
200 mL of latex emulsion (JSR0696, manufactured by JSR) is placed in a 500 mL measuring cylinder. After adjusting the temperature to 70 ° C., the diffuser stone is put into the liquid, and air (1000 L / min) is sent in and foamed. When the foam height reaches 500 mL, 0.1 g of an antifoaming agent is added dropwise. The foam height after 1 minute was defined as the initial defoaming property, and the foam height after 30 minutes was defined as the continuous defoaming property. The lower the height, the better the defoaming performance.

【The invention's effect】
The defoamer composition of the present invention is excellent not only in the initial defoaming property but also in the sustained defoaming property.
