Abstract

An aspect of the present disclosure relates to a functional defoaming agent composition, and more particularly to an environmentally-friendly defoaming agent composition containing loess. In an aspect, a loess-based, environmentally-friendly functional defoaming agent includes: 1-20 wt % loess; 10-30 wt % silicone resin having a kinematic viscosity of 10-50,000 cst; 1-5 wt % thickening agent; 1-10 wt % natural surfactant; 1-10 wt % water-purifying agent; and 60-80 wt % water. In another aspect, a loess-based, environmentally friendly functional defoaming agent includes: 1-20 wt % inorganic mixture of loess with at least one selected from among elvan, tourmaline and germanium; 10-30 wt % silicone resin having a kinematic viscosity of 10-50,000 cst; 1-5 wt % thickening agent; 1-10 wt % natural surfactant; 1-10 wt % water-purifying agent; and 60-80 wt % water.

Claims (6)

1. A loess-based, environmentally friendly functional defoaming agent comprising: 1-20 wt % of loess; 10-30 wt % of a silicone resin having a kinematic viscosity of 10-50,000 cst; 1-5 wt % of a thickening agent; 1-10 wt % of a natural surfactant; 1-10 wt % of a water-purifying agent; and 60-80 wt % of water,

wherein the natural surfactant is prepared by adding 0.05-0.2 parts by weight of a catalyst to 100 parts by weight of a 1:5-1:7 mixture of natural fatty acid and α,γ-hydroxysiloxane.

2. A loess-based, environmentally friendly functional defoaming agent comprising: 1-20 wt % of an inorganic mixture of loess with at least one selected from among elvan, tourmaline and germanium; 10-30 wt % of a silicone resin having a kinematic viscosity of 10-50,000 cst; 1-5 wt % of a thickening agent; 1-10 wt % of a natural surfactant; 1-10 wt % of a water-purifying agent; and 60-80 wt % of water,

wherein the natural surfactant is prepared by adding 0.05-0.2 parts by weight of a catalyst to 100 parts by weight of a 1:5-1:7 mixture of natural fatty acid and α,γ-hydroxysiloxane.

3. The loess-based, environmentally friendly functional defoaming agent of claim 1 , wherein the average particle diameter of the loess is 100-500 μm.

4. The loess-based, environmentally friendly functional defoaming agent of claim 2 , wherein the average particle diameter of the inorganic mixture is 100-500 μm.
