Abstract

The present invention relates to a method of recycling a waste acrylic resin, which provides an effective technology for recycling waste acrylic resin by comprising: step A of performing thermal decomposition by raising the temperature of a waste acrylic resin to 450 ℃ or higher to thereby extract water and acrylic monomer mixture; and step B of obtaining acrylic monomers by cooling the water and acrylic monomer mixture extracted from the step A to 200 to 250 ℃ and separating the acrylic monomers. According to the present invention, the waste acrylic resin is separated through thermal decomposition, and thus acrylic monomers can be separated regardless of the molecular weight of waste acrylate. Additionally, a high-purity acryl can be obtained because the acrylic monomer which has a high boiling point is separated first, prior to water. Also, it is possible to prevent additional environmental contamination by filtering toxic gas which may be produced during a recycling process.
