Optimization of the Preparation Process of Nano-Sized Calcium Carbonate with Low DOP Absorbency Applied in Plastic

Abstract:

This article filters sodium acetate as better additives by comparing the calcium carbonate obtained in the different dosage and adding manner for different additives. We discuss impact of four factors such as the amount of additives, the amount of dispersant, additive time of additives and initial temperature of carbonation on low DOP absorbency in the process of preparation of nano-sized calcium carbonate applied in plastic. And preparation conditions of this product which is to reduce DOP absorbency are studied. Nano-sized calcium carbonate with DOP absorbency of about in 40mL/100g (CaCO₃ dry basis) applied in plastic is prepared. And the reparation conditions are the additive amount of 0.20% (CaCO₃ dry basis), the amount of dispersant of 0.2% (CaCO₃ dry basis), adding additives 5 min after the start carbonization and Carbonization temperature to 20°C.
