解決に当たっている。[0003] However, the inorganic heat insulating material treated only with the above-mentioned additives generates dust when cut into predetermined dimensions,
The worker or the contractor must take appropriate measures such as putting on a mask. Conventionally, as a countermeasure against this dust, a problem has been solved by using a dust inhibitor (such as mineral oil) in combination with the above additive.

付着したものでは50℃を超えてしまう)。 2)単独使用においては、撥水性のあるものがない。 3)従って、どうしてもシリコーン樹脂との併用が必要
である。As mentioned above, the dust inhibitor has a certain dust-preventing effect. 1) In the base material test of the non-combustible material test according to the Ministry of Construction Notification No. 1828, the criteria for judging the temperature are as follows. Where the value is 50 ° C or less, 4
9 ° C., which is close to the criterion value (however, 2% adhesion, for example, 0.5 to 2.0% of mineral oil per 1 kg of glass wool)
If it adheres, it will exceed 50 ° C). 2) When used alone, none of them have water repellency. 3) Therefore, it is absolutely necessary to use the silicone resin together with the silicone resin.
