(4) the reacted slurry of step (3) gained leaves standstill 9-12h, dry 6-7 hour at 50-60 DEG C, after vacuum-drying at 80-100 DEG C, obtain compound calcium carbonate powder;
(5) step (4) gained compound calcium carbonate powder is placed on rotary drum, preheating 10-20min at 40-50 rev/min lower 30-40 DEG C, again stearic acid is heated to 70-80 DEG C, atomization, evenly be sprayed on compound calcium carbonate powder, at 30-50 DEG C, 30-40 rev/min is stirred 30-35min, after stopping operating, and standing 20-30min and get final product.
Beneficial effect of the present invention is:
(1) sisal fibers is strong but pliable in texture, wear-resisting, Salt And Alkali Tolerance, corrosion-resistant, by modified, more composite with the calcium carbonate of modification after, regrind modification, makes itself and calcium carbonate can be good at compatible, makes that the PVC that obtains is wear-resisting, corrosion-resistant, acid and alkali-resistance simultaneously;
(2) the present invention is dispersed by adding dispersion agent, effectively prevents the autohemagglutination of miniaturization particle, increases its consistency in plastics, rubber and dispersiveness;
(3) the present invention adopts the mode of atomizing spray to make use of stearic acid cmpletely, adopts vacuum drying method, makes to avoid compound powder secondary agglomeration;
(4) product application that obtains of the present invention is in PVC plastic, because the properties-correcting agent of its surface chemistry bonding and PVC plastic have excellent compatibility, show strong interior lubrication, thus weaken the intermolecular reactive force of PVC, system rheological performance is changed, can extruded velocity be improved, make the smooth exquisiteness of products appearance; Also illustrate under equal conditions, modified calcium carbonate can increase loading level, also can reach well cost-saving effect simultaneously.
