In order to prepare the good-adherent and weather-resistant acrylic resin coatings, acrylic resin was prepared by a radical polymerization of monomers(BA,styrene,MMA,BMA,DMAEMA). Glass transition temperature (Tg) of the acrylic copolymer was fixed at 30°C and the contents of DMAEMA was varied to be 5, 10, 15, 20 wt% respectively, and the contents of strene was 10% fixed. GPTMScontaining epoxy group was used for curing agents. The equivalent ratio of amine to epoxy was 1:1.The gloss retention and color difference were improved at low tertiary amine concentration. The coatings containing 10wt% tertiary amine concentration have especially good weather resistant properties. |
