The present invention relates to a method of using an anti-scattering agent composition.

Materials such as general houses and buildings, car bodies, ducts, piping, and other equipment are used as insulation and soundproofing materials by impregnating glass wool or rock wool with an adhesive called a binder and then firing them to form them. is used. Glass wool and rock wool are cotton-like materials made of ultra-fine glass fibers and are easily scattered around during processing. It is also difficult to uniformly penetrate glass wool or rock wool using only a binder. Therefore, in the manufacturing process of heat insulating materials and soundproofing materials using glass wool or rock wool, an anti-scattering agent is used along with a binder. The anti-scattering agent has the effect of making it easier for the binder to uniformly permeate glass wool or rock wool, and suppressing scattering around the glass wool or rock wool.

Various studies are being conducted on anti-scattering agents suitable for firing glass wool and rock wool. For example, Patent Document 1 discloses that an amine salt of a fatty acid having 6 to 24 carbon atoms is added to a predetermined base oil without using a surfactant, with the aim of providing a glass wool anti-scattering agent that does not leave a hygroscopic residue. This patent discloses a glass wool anti-scattering agent containing a predetermined amount of the following.
