METHOD FOR PRODUCING DRY GROUND CALCIUM CARBONATE FOR USE IN THERMOSET POLYESTER RESIN SYSTEMS |
摘要 |
<p>A dry ground calcium carbonate filler or additive made by dry grinding calcium carbonate in the presence of an organo-amine and then surface treating the ground calcium carbonate with a dispersant and the method of making the same is disclosed. Dry ground calcium carbonate filler or additive made by dry grinding calcium carbonate in the presence of an organo-amine such as triethanolamine and then surface treating the ground calcium carbonate with a dispersant such as sodium polyacrylate when added to a polyester polymer composition yields a lower viscosity of the polymer system than without the addition of triethanolamine followed by surface treating the ground calcium carbonate with a dispersant.</p> |
