| 摘要 |
The object of the invention is the use, as a thickening agent for a water-based paint, of an aqueous solution of a polyether of at least one polyoxyalkylene and at least one alpha-olefin epoxy, and/or at least one aliphatic or aromatic glycidyl ether, and at least one surface active agent whose chemical formula is CxH2x+1—(OX)y—OH where OX designates an oxylakylated unit, and characterized in that: for the polyether, the molar ratio (polyoxyalkylene:alpha-olefin epoxy or aliphatic or aromatic glycidyl ether) is between (1:4) and (1:10), for the surface active agent, 6≰x≰12 and 5≰y≰12, said solution exhibits a mass ratio (polyether/surface active agent) of between 2.0 and 0.5, and exhibits a water content of 30% to 75% of its total weight. Another object is the paint containing such a thickening system.
