Abstract

The invention discloses a titanium dioxide and polyethylene dual-coated calcium carbonate inorganic filler and a production method thereof. The titanium dioxide and polyethylene dual-coated calcium carbonate inorganic filler is produced from, by weight, 40-50 parts of calcium oxide, a proper amount of CO2, 5-10 parts of acetylacetone, 6-12 parts of sodium stearate, 15-25 parts of butyl titanate, 25-35 parts of polyethylene resin, 8-12 parts of dimethicone and 200-250 parts of deionized water. Calcium carbonate powder is dual-coated with titanium dioxide and the polyethylene resin, so the acid resistance, the whiteness and the fireproof performance of the calcium carbonate powder are enhanced, and the integration of the inorganic filler and an organic base is improved to make the inorganic filler meet requirements of wide application.

Description

A kind of titanium dioxide, polyethylene dual cladding calcium carbonate inorganic filler and its preparation Method
Technical field
The present invention relates to a kind of composite modified calcium carbonate powder and its preparation, more particularly to a kind of titanium dioxide, polyethylene Dual cladding calcium carbonate inorganic filler and preparation method thereof.
Background technology
The surface modification treatment of powder body is exactly the needs according to powder body material application, using methods such as physics, chemistry, machineries Purposefully change the physicochemical properties of powder body material surface, such as surface composition, structure and functional group, surface energy, surface profit Moist, electrical, photosensitiveness, absorption and response characteristic etc., to meet the needs of modern material and development of new techniques.In plastics, people In making the industry of marble Polymer material and polymer composites materials application, calcium carbonate powder filler occupies critically important Status.Pearl filler not only can lower the production cost of material, moreover it is possible to improve hardness, rigidity or the dimensionally stable of material Property, improves the mechanical property of material and gives material some special physical and chemical performances, such as corrosion resistance, weatherability, fire-retardant Property and insulating properties etc..But the surface due to pearl filler and substrate, i.e. organic polymer or interfacial property are different, the compatibility compared with Difference, therefore, it is difficult to it is dispersed in substrate, fill directly or too much and tend under some mechanical properties for causing material The shortcomings of dropping and be brittle.Therefore, in addition to the requirement of the granularity to pearl filler and particle size distribution, it is necessary to it Modifying surface, to improve the physicochemical characteristicss on its surface, strengthen its with organic polymer or resin etc. matrix it is compatible Property and the dispersibility in organic matrix, to improve the mechanical performance and combination property of material.
Section its master thesis fortunately《The dry surface modification research of calcium carbonate superfine powder powder body》In, using Oleic acid-horse Carry out anhydride composite modifier to be modified calcium carbonate powder, but when Calcium Carbonate is used as fillers such as plastics, coating, also exist That acid resistance is not good, 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：
A kind of titanium dioxide, polyethylene dual cladding calcium carbonate inorganic filler, it is characterised in that by the raw material system of following weight portion Into：
Calcium oxide 40-50, CO2In right amount, acetylacetone,2,4-pentanedione 5-10, sodium stearate 6-12, butyl titanate 15-25, polyvinyl resin 25-35, dimethicone 8-12, deionized water 200-250.
Described a kind of titanium dioxide, polyethylene dual cladding calcium carbonate inorganic filler and preparation method thereof, its feature exists In being 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 are added in step a gained calcium carbonate serosity, is ground in grinder After stirring, butyl titanate is slowly added dropwise in grinding, continues to grind 0.5-1h after terminating, butyl titanate is in acetylacetone,2,4-pentanedione Under effect, hydrolysis generates titanium dioxide fine particles, and under the activation of sodium stearate, is coated on calcium carbonate granule surface；It is right The Calcium Carbonate of cladding titanium dioxide microgranule is filtered, drying, is then crushed, and obtains the Paris white of cladding titanium dioxide；
C. by step b gained Paris white input high speed mixer, polyvinyl resin, dimethicone, stirring is added to heat up To 90-110 DEG C, after insulated and stirred 10-30min, Jing double screw extruder extruding pelletizations.
Described a kind of titanium dioxide, polyethylene dual cladding calcium carbonate inorganic filler and preparation method thereof, its feature exists In 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.
Specific embodiment
With reference to embodiment, the specific embodiment of the present invention is further described.
