Abstract
The present invention relates to a functional fluid composition comprising a glycol as a base material and a diamine-based noise reducer. According to the present invention as such, the functional fluid composition comprising a glycol as a base material and a diamine-based noise reducer represented by chemical formula 1 has an excellent noise reducing effect. In addition, the functional fluid composition of the present invention has an excellent metal corrosion inhibiting effect even, by using a diamine-based compound as a noise reducer, when a metal corrosion inhibitor composed of a triazole-based compound without including an amine-based compound is used as a metal corrosion inhibitor.
