【Abstract】 Amphiphiiic acrylic acid copolymer resin(WDR-PAA) was prepared by hydrophilic monomer,hydrophobic monomer,and functional monomer(diacetone acrylamide:DAAM).The effect of acid value and DAAM concentration on the water-solubility was investigated.The coating properties of the amphiphiiic acrylic acid copolymer resin and its film were measured,which showed excellent properties in hardness,gloss and water resistance. It was applied to prepare the humidity-sensitive breathable coatings.The amphiphiiic acrylic copolymer contain many carboxyl groups and high hydroxy groups.Therefore,the amphiphilic acrylic copolymer resin film shows good water absorption property.The water-sensitive breathable coatings consist of the amphiphilic acrylic copolymer and porous fillers.According to measuring absorption/dehumidity properties of the coating and the surface morphology analysis,it could be widely applied in indoor coating for controlling humidity.更多还原
