| titleOfInvention | Modified acrylic resin and preparation method thereof |
| abstract | The invention discloses a modified acrylic resin and a preparation method thereof, wherein the modified acrylic resin is prepared from the following main raw materials: the modified acrylic resin comprises hydroxy acrylic resin, isocyanate and polyaspartic acid ester, wherein the hydroxy acrylic resin comprises the following raw materials in percentage by weight: 28-32% of organic solvent, 40-51% of hard monomer, 3-7% of soft monomer, 10-12% of hydroxyl monomer and 4-5% of initiator. According to the invention, through introducing the polyaspartic acid ester, a hydroxyl group with low reaction activity on the original hydroxyl acrylic resin is replaced by a high-activity amino group, so that the reaction speed of the resin and a-NCO group in a curing agent is improved, the curing speed of a paint film is obviously accelerated, the drying time is shortened, the time interval for polishing the paint film is reduced, the baking process in the conventional production can be cancelled, the energy is saved, and in addition, the adhesive force, the chemical corrosion resistance and the aging resistance of the paint film are also improved. |
