Abstract

The present invention provides modified heavy calcium carbonate for a fire retardation electric cable material. The modified heavy calcium carbonate is prepared from the following raw material components, by weight: 95-100 parts of calcium carbonate, 1-2 parts of octylphenol polyoxyethylene ether, 0.2-0.3 part of peregal O, 1-1.5 parts of dioctyl maleate, 0.2-0.4 part of zinc stearate, 0.1-0.2 part of magnesium oxide, 0.1-0.3 part of polyethylene wax, 0.1-0.4 part of an ultraviolet absorber UV-P, 1-2 parts of chitosan, 1-1.5 parts of polyphosphoric acid, and 2-3 parts of methyltriethoxysilane. The preparation method comprises: drying calcium carbonate, adding other raw materials according to the ratio, completely mixing in a high speed stirrer, and carrying out drying and grinding to obtain the finished product. The obtained modified calcium carbonate has characteristics of good dispersity and good ultraviolet resistance, and can be used for fire retardation electric cable materials so as to reduce cost and improve various processing performances of the electric cable material.

Description

Modified calcium carbonate and preparation method thereof for a kind of uvioresistant CABLE MATERIALS
Technical field
The present invention relates to mineral filler field, be specifically related to modified calcium carbonate and preparation method thereof for a kind of uvioresistant CABLE MATERIALS.
Background technology
Water-ground limestone is a kind of conventional mineral filler, and, low price wide because originating etc., are widely used in the fields such as rubber, plastics, coating.But water-ground limestone surface hydrophilic oleophobic, specific surface area are large, surface can be high, very easily reunite between particle, when directly or in a large number filling in organic basis material, not only be difficult to disperse equably, and very weak with the bonding force of matrix, cause some degradation of two-phase interface defect, matrix material.Therefore, in order to widen its Application Areas, must make its surperficial oleophilic drainage to water-ground limestone modifying surface, the consistency of enhancing and organic matrix, improves the dispersiveness in organic matrix, improves the performance of matrix material.
Summary of the invention
The invention provides modified calcium carbonate and preparation method thereof for a kind of uvioresistant CABLE MATERIALS.
The technical scheme of employing of the present invention is as follows:
A CABLE MATERIALS modified calcium carbonate, is characterized in that, by the feed composition of following weight part, is prepared from:
Calcium carbonate 95-100, polyoxyethylene octylphenol ether 1-2, paregal O 0.2-0.3, dioctyl maleate 1-1.5, Zinic stearas 0.2-0.4, magnesium oxide 0.1-0.2, polyethylene wax 0.1-0.3, Ultraviolet Absorber UV-P 0.1-0.4, chitosan 1-2, polyphosphoric acid 1-1.5, Union carbide A-162 2-3.
The preparation method of modified calcium carbonate for described uvioresistant CABLE MATERIALS, is characterized in that: concrete operations are:
Calcium carbonate is dried to moisture content below 0.3% at 80-85 ℃ of temperature, then add in high-speed mixer, first add in proportion polyoxyethylene octylphenol ether, paregal O, speed high-speed stirring 3-5 minute with 800-1000 rev/min, then adding dioctyl maleate, high-speed stirring 5-6 minute, adding successively Zinic stearas, magnesium oxide, polyethylene wax, Ultraviolet Absorber UV-P, chitosan, polyphosphoric acid, Union carbide A-162, speed high-speed stirring 15-20 minute with 1000-1200 rev/min, then dry, obtain modified calcium carbonate.
Beneficial effect of the present invention:
The present invention has added kinds of surface treatment agent and functional agent on the basis of existing water-ground limestone modification, the modified calcium carbonate of gained has particle diameter and is less than 0.1um, size of particles is more even, specific surface area is large, application performance be greatly better than the feature of ordinary calcium carbonate, the modified calcium carbonate that obtains in polyvinyl chloride resin dispersiveness and consistency good, can improve the add-on of filler, lower material cost; When modification, pass through to add a small amount of UV light absorber, greatly improved the anti-ultraviolet property of CABLE MATERIALS, be applied in the production of PVC CABLE MATERIALS, can reduce the consumption of UV light absorber, further reduce material cost, increase economic efficiency, mobility and the processing characteristics of system have been improved, and give goods good physical and mechanical properties, and reach toughened and reinforced effect, improved anti-ultraviolet function.
Embodiment
The preparation method of modified heavy calcium carbonate for a kind of fire-resistant cable material:
(kg) takes water-ground limestone 100, polyoxyethylene octylphenol ether 1, paregal O 0.3, dioctyl maleate 1, Zinic stearas 0.2, magnesium oxide 0.1, polyethylene wax 0.3, Ultraviolet Absorber UV-P 0.1, chitosan 2, polyphosphoric acid 1, Union carbide A-162 3 by weight
Calcium carbonate is dried to moisture content below 0.3% at 82 ℃ of temperature, then add in high-speed mixer, first add in proportion polyoxyethylene octylphenol ether, paregal O, with the speed high-speed stirring of 800-1000 rev/min 4 minutes, then adding dioctyl maleate, high-speed stirring 6 minutes, adding successively Zinic stearas, magnesium oxide, polyethylene wax, Ultraviolet Absorber UV-P, chitosan, polyphosphoric acid, Union carbide A-162, again with the speed high-speed stirring of 1000-1200 rev/min 18 minutes, then dry, grind, obtain modified calcium carbonate.
We produce respectively hard, flexible PVC test piece by common water-ground limestone and modified heavy calcium carbonate, on INSTRON4466 type universal testing machine, test, test result relatively in Table 1, table 2.
The comparison of table 1 hard PVC test piece test result
Figure BDA0000344849651
The comparison of table 2 flexible PVC test piece test result
Figure BDA0000344849652
From table 1, table 2, can find out, the in the situation that of same addition, hard, the flexible article of PVC no matter, use modified calcium carbonate, the elongation at break that the mechanical property of test piece is all obviously better than ordinary calcium carbonate, particularly test piece doubles many, and material easily plastifies, roll banding not, surface brightness is high, and processing characteristics is good.
