Abstract

The invention provides a compound wetting agent and a coating formed by the same. The compound wetting agent mainly comprises, by weight, 5-40% of polyether modified organosilicon surfactant, 50-90% of alkynediol surfactant and 1-10% of isomerized low-foam special polyether solubilizer. The compound wetting agent has low static surface tension and dynamic surface tension and good system compatibility, foam stability of polyether modified organosilicon is remarkably improved, and the compound wetting agent can be suitable for water-based wood paint of different resin systems such as an acrylic resin system and a polyurethane system.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a composite wetting agent and the coating composed of the same. Background technique [0002] In water-based wood varnishes, the solid content of resin accounts for about 30%, and the remaining 60% to 70% are water and organic solvents. The surface tension of water is high, 72mN / m, and the wettability to the substrate is poor; the water-based resin system is emulsion type or water dispersion type. If it is to disperse stably, it needs to add a variety of additives, which is a relatively complicated system. Compared with the solvent type, the compatibility of the system is prone to problems. The surface tension of water is high, and the surface tension of co-solvent is low. To achieve good wetting and spreading effects, it is necessary to select an appropriate substrate wetting agent. Substrate wetting agent can effectively reduce the surface tension of the system, increase the wettabili...
