Abstract
The invention discloses a thermoplastic acrylic resin. The thermoplastic acrylic resin comprises, by weight, 100 parts of methacrylate, 15-25 parts of methacrylic acid, 25-30 parts of styrene, 3-5 parts of an initiator, 0.5-1.5 parts of a catalyst and 35-50 parts of an organic solvent. A coating prepared by using the thermoplastic acrylic resin can be applied by diluting with an organic solvent, can also be applied by hot melting, and has good adhesive force to surfaces of cement, asphalt and plastics. The thermoplastic acrylic resin can be used for manufacturing plastic paint, road sign coating, floor paint and high-grade wood furniture paint.
