| titleOfInvention | A kind of surface treatment method of the nano-calcium carbonate of filled PVC plasticized paste |
| abstract | The invention discloses a kind of surface treatment method of the nano-calcium carbonate of filled PVC plasticized paste, comprise the following steps：Nano-calcium carbonate slurries after carbonating are delivered in surface processing trough, control temperature stirs at 50~80 DEG C；Added under stirring by the saturated fatty acid that mass ratio is 1: 0.5~3 and the surface conditioning agent that ricinoleate ester sodium sulphate forms, persistently stir 60~90min, the surface for completing nano-calcium carbonate is modified；It is filtered again, it dry, pulverize, finally sieve, you can obtain product.This method is surface-treated using the compounding mixture of saturated fatty acid and ricinoleate ester sodium sulphate to nano-calcium carbonate, and the nano-calcium carbonate after processing can effectively improve the thixotropy of filled PVC plasticized paste, yield value and rheological stability etc..This method technique is simple, and cost is low, and operation is easy, is suitable for industrial production, has preferable economic benefit and social benefit. |
