The activated Calcium carbonate containing gac of described a kind of high-compatibility, is characterized in that: preparation method comprises the following steps:
(1) calcium carbonate is added after in homogenizer, then add oleic acid, stearylamide, paraffin, stir at 60-70 DEG C under 100-180rpm, obtain modified calcium carbonate for subsequent use;
(2) gac is joined in appropriate amount of deionized water, after stirring at 40-45 DEG C, then ramie pulp fiber, ferric oxide, chitosan are added wherein, stir at 45-50 DEG C, then grind 1-2 hour, obtain combination solution;
(3) modified calcium carbonate and combination solution are mixed, ball milling mixes and obtains mixed slurry, adds all the other raw materials except stearic acid, reacts 10-30min at 45-48 DEG C;
(4) the reacted slurry of step (3) gained leaves standstill 5-8h, dry 8-9 hour at 70-80 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) the present invention with the addition of gac composition, effectively be dispersed in system, after grinding distribution together with the oleic acid of the modifications such as oleic acid and ramie pulp fiber, obtain one can be well compatible with PVC activated Calcium carbonate, thus make by its obtained smooth exquisiteness of PVC surface;
(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; Also illustrate under equal conditions, modified calcium carbonate can increase loading level, also can reach well cost-saving effect simultaneously.
