Abstract
Disclosed is a preparation method for a high-solid acrylic resin, comprising the following steps: preparing acrylic acid or methacrylic acid, an alkyl acrylate or alkyl methacrylate, styrene, hydroxyethyl acrylate or hydroxypropyl acrylate, an acrylate with a bridge ring structure, an initiator, and a solvent; adding the solvent to a reactor, stirring, and increasing the temperature to the boiling point temperature of the solvent; adding the reaction raw materials and the initiator from a dropping funnel and stirring, and after the completion of the addition, maintaining the boiling point temperature of the solvent and continuously stirring; and cooling and discharging after the reaction is finished. The Gardner-Holdt tube viscosity of the prepared acrylic resin is 15-25 S (25° C.), and the solid content is 70%-75%.
