Abstract
The invention discloses easily secondarily modified polydopamine coated modified calcium carbonate powder with high reaction activity. A polydopamine film is modified on the surface of calcium carbonate, the surface of the polydopamine film contains a large number of active functional groups, more possibility is provided for further modification of the calcium carbonate powder, the modified powder is modified by titanate coupling agents, modification effects are more excellent, oil absorption, dispersibility and surface affinity of the obtained calcium carbonate powder are effectively improved, reaction activity with various systems is higher, and the powder is more economical and efficient and wider in use range.
Description
Technical field
The present invention relates to Surface Modification of Inorganic Powder technical field, more particularly to one kind is easy to secondary modification high reaction activity
Poly-dopamine coating modification calcium carbonate powder and preparation method thereof.
Background technology
Calcium Carbonate is a kind of very common inorganic powdered filler, and its cheap, nonpoisonous and tasteless, whiteness is high, hardness is good
The advantages of, it is widely used in rubber, papermaking, ink, plastics, coating etc. field, however, Calcium Carbonate is substantially
A kind of inorganic mineral, poor with the affine compatibility of organic substance, directly filling will cause properties of product serious deterioration, use
Scope critical constraints, therefore, need in actual applications to be modified calcium carbonate powder process.
Method of modifying main at present has mechanical refinement method, surface modifier such as coupling agent, fatty acid and its salt, surface to live
Property modified two big class such as agent, two methods respectively have its advantage, and modified Calcium Carbonate performance is also improved.《Hard Fat
Acid-titanate coupling agent modified heavy calcium carbonate powder research》One text is using stearic acid, titanate coupling agent as composite modified
Agent, dehydrated alcohol to powder body are modified process using wet ball grinding as dispersant, achieve ideal modified effect
Really, but the product for preparing of this method is hydrophobicity product, in water color ink, water paint field using being limited
System, and additional function is not enough, is only limitted to strengthening and toughening use, needs to do further modification, to widen its use range.
The content of the invention
The object of the invention is exactly for the defect for making up prior art, there is provided a kind of secondary modification high reaction activity that is easy to
Poly-dopamine coating modification calcium carbonate powder and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of poly-dopamine coating modification calcium carbonate powder for being easy to secondary modification high reaction activity, the modified calcium carbonate powder body by
The raw material of following weight portion is made：Calcium Carbonate 50, titanate coupling agent 2-3, dehydrated alcohol 60-80, Dopamine Hydrochloride 4-5, pH
It is worth the Tris-HCl buffer 60-80 for 8-8.5.
A kind of preparation side of described poly-dopamine coating modification calcium carbonate powder for being easy to secondary modification high reaction activity
Method is comprised the following steps：
（1）First Dopamine Hydrochloride is put in Tris-HCl buffer, is stirred to which and after being completely dissolved, is put into Calcium Carbonate, mixing is ground
After mill dispersion 20-30min, modification 25-30h is stood, subsequently system is washed 2-3 time, system is dried after being disposed, gained
Powder body is standby；
（2）By step（1）The powder body of preparation is put in dehydrated alcohol together with titanate coupling agent, hot blast after ball milling 20-30min
It is dried, completely removes solvent, after grinding distribution, obtains final product described modified calcium carbonate powder body.
It is an advantage of the invention that：The present invention modifies poly-dopamine film in calcium carbonate surface, and poly-dopamine film surface contains
Substantial amounts of active function groups, are further being modified there is provided more probabilities for calcium carbonate powder, the powder body of modification Jing titaniums again
The coupling agent modified process of acid esters, modified effect are more excellent, and calcium carbonate powder oil factor, dispersibility and the surface for obtaining is affine
Degree etc. is effectively improved, and higher with the reactivity of various systems, product more economical and efficient, use range are wider.
Specific embodiment
A kind of poly-dopamine coating modification calcium carbonate powder for being easy to secondary modification high reaction activity, the modified calcium carbonate powder
Body is made up of the raw material of following weight portion：Calcium Carbonate 50, titanate coupling agent 2, dehydrated alcohol 60, Dopamine Hydrochloride 4, pH value are
8 Tris-HCl buffer 60.
The embodiment raw powder's production technology is comprised the following steps：
（1）First Dopamine Hydrochloride is put in TrisHCl buffer, is stirred to which and after being completely dissolved, is put into Calcium Carbonate, mixing is ground
After mill dispersion 20min, modification 25h is stood, subsequently system is washed 2 times, system is dried after being disposed, gained powder body is standby
With；
（2）By step（1）The powder body of preparation is put in dehydrated alcohol together with titanate coupling agent, hot air drying after ball milling 20min
It is dry, solvent is completely removed, described modified calcium carbonate powder body after grinding distribution, is obtained final product.
Obtained calcium carbonate powder the performance test results are：
Granularity D50：0.65μm；Viscosity：34.8mPa.s activation grades：95.5%；Oil factor：0.36ml/g；Settling volume：
1.62ml/g。
