Abstract

The invention discloses a preparation method of calcium rosin derivative chelate modified nano or light CaCO3 powder. The method comprises the following steps: smashed rosin / modified rosin or isolatedpine resin acid is added to acrylic acid or fumaric acid, the mixture is blended with excess Ca(OH)2 solution or lime milk and a surfactant, saponification is performed, and rosin / modified rosin derived calcium and calcium chelate or isolated resin acid derived calcium and calcium chelate are generated; then CO2 and excess Ca(OH)2 or lime milk are subjected to a reaction by means of supercavitation, CaCO3 is generated, nano or light CaCO3 precipitates modified with calcium rosin derivative chelate are prepared from rosin / modified pine resin acid or isolated pine resin acid and pine resin acidderived calcium and calcium chelate, and a powder material is prepared through pneumatic drying. The method adopts a simple process, the obtained calcium rosin derivative chelate modified nano or light CaCO3 powder has excellent performance, can remarkably improve physical properties of a material when used as an auxiliary or a modifying material and can be widely applied to various fields.
