초록

Environmental friendly acrylic/urea high-solid paint(MUHC) were prepared through the curing reaction of acrylics resin(EBHC) containing 70wt% of solids content and butylated urea curing agent. The synthesis of EBHC Was done at $150^{\circ}C$ for 6 hours, and the results were obtained as follows : $M_{n}=1830{\sim}2190$, $M_{w}$ $3290{\sim}4000$, $M_{w}/M_{n}$=1.80{\sim}1.83$ viscosity=$110{\sim}352$ cps, and conversion=$82{\sim}92$%. After the film was coated with MUHC, the various physical properties were measured. They showed that enhancement of the coating properties such as adhesion, flexibility, abrasion resistance, impact resistance, and water resistance could be expected through introdl1cing caprolactone acrylate component in acrylics resin for the high-solids content acrylics/urea coatings.
