Description
Technical field
The present invention relates to a kind of composite modified calcium carbonate powder and its preparation, more particularly to a kind of butadiene-styrene rubber it is modified two
Titanium-oxide-coated calcium carbonate inorganic filler and preparation method thereof.
Background technology
Calcium Carbonate（Including triple superphosphate and fine particle calcium carbonate）It is easy to get with raw material, cheap, good stability, color and luster is simple, nontoxic etc.
The fields such as plurality of advantages, and be widely used in plastics, rubber, papermaking, ink, building materials, electric wire, become that consumption is maximum to be filled out
Fill material.But because Calcium Carbonate belongs to inorganic particle, particle surface is hydrophilic oleophobic, in highly polar, is difficult in organic media
It is uniformly dispersed, adhesion is low between base material, when by external impacts, easily causes boundary defect, causes material property to decline.Receive
The calcium carbonate powder of meter level, surface energy is high, and adsorption is stronger, and particle is reunited mutually, it is impossible to divided very well in polymeric matrix
Dissipate, so as to the actual effect for affecting it to use.Therefore, only Calcium Carbonate being modified could obtain high-performance and meet actual
Using functional modification filling PP Pipe Compound.
Liang Jin is in its master thesis《The preparation of nano-calcium carbonate and Research on Surface Modification》In, prepared using carbonizatin method
Nano-calcium carbonate, and it is modified with sodium stearate, but when Calcium Carbonate is used as fillers such as plastics, coating, also deposit
It is not good in acid resistance, the shortcomings of shortcoming with the amalgamation at organic group bottom.
The content of the invention
Thinking based on more than, the present invention is intended to provide a kind of composite modified calcium carbonate inorganic filler and preparation method thereof,
To solve when Calcium Carbonate is used as fillers such as plastics, coating, the acid resistance for existing is not good, is short of with the amalgamation at organic group bottom
The shortcomings of.
The technical problem to be solved is realized using following technical scheme：
The modified coated by titanium dioxide calcium carbonate inorganic filler of a kind of butadiene-styrene rubber, it is characterised in that by the original of following weight portion
Material is made：
SBR emulsion 3-6, calcium oxide 40-50, sodium alginate 1-2, CO2In right amount, acetylacetone,2,4-pentanedione 5-10, sodium stearate 6-
12, carbide slag 1-2, butyl titanate 15-25, polyvinyl resin 25-35, dimethicone 8-12, deionized water 200-250；
The content of the SBR emulsion is 5-40%.
Modified coated by titanium dioxide calcium carbonate inorganic filler of described a kind of butadiene-styrene rubber and preparation method thereof, its feature
It is to be made up of following steps：
A. calcium oxide solid is crushed into powdered, adds deionized water, stirring reaction 2-3h at 60-100 DEG C is reacted
After serosity ageing 1-3h, serosity is transferred in carburizing reagent kettle, CO2Mixed after spinner flowmeter metering with air, led to
Enter the gas distributor in carburizing reagent bottom portion；As pH ＜ 7, terminate reaction, obtain calcium carbonate serosity；
B. at 70-90 DEG C, acetylacetone,2,4-pentanedione, sodium stearate, sodium alginate are added in step a gained calcium carbonate serosity, in grinding
After grinding stirs in machine, butyl titanate is slowly added dropwise in grinding, continues to grind 0.5-1h after terminating, butyl titanate is in second
In the presence of acyl acetone, hydrolysis generates titanium dioxide fine particles, and under the activation of sodium stearate, is coated on calcium carbonate granule
Surface；The Calcium Carbonate of cladding titanium dioxide microgranule is filtered, is dried, then crushed, obtain the carbonic acid of cladding titanium dioxide
Calcium powder；
C. by step b gained Paris white input high speed mixer, polyvinyl resin, carbide slag, butadiene-styrene rubber breast are added
Liquid, dimethicone, stirring is warming up to 90-110 DEG C, after insulated and stirred 10-30min, and Jing double screw extruder extruding pelletizations are
Can.
Modified coated by titanium dioxide calcium carbonate inorganic filler of described a kind of butadiene-styrene rubber and preparation method thereof, its feature
It is, CO in step a2Flow is 0.04-0.40L/g (CaO) min, and reaction temperature is 15-45 DEG C.
The invention has the beneficial effects as follows：In the presence of acetylacetone,2,4-pentanedione, hydrolysis generates titanium dioxide fine particles to butyl titanate, and
Under the activation of sodium stearate, calcium carbonate granule surface is coated on, enhances the acid resistance of calcium carbonate powder, whiteness and resistance to
Fiery performance so as to meet wider application requirement；With polyethylene the calcium carbonate powder of cladding titanium dioxide is carried out again afterwards
Coat again, be lipophile by the hydrophilic characteristic transition of gained powder body, promote its fusion with organic group bottom, make gained carbonic acid
Calcium powder physical ability is preferably applied to the fields such as plastics, coating；The dimethicone for adding therebetween, prevents the group between Calcium Carbonate
It is poly-, while promoting dispersion of the Calcium Carbonate in polyvinyl resin so as to parcel it is more uniform；The addition of SBR emulsion
Avoid to prepare in nano-calcium carbonate powder process and operation and its energy consumption brought and the dust pollution such as be dried, crush.
