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: 90-100 parts of heavy calcium carbonate, 0.2-0.5 part of butyl naphthalene sulfonate, 0.5-0.8 part of sodium alcohol ether sulphate, 1-2 parts of epoxidized triglyceride, 0.1-0.2 part of stearic acid, 0.1-0.2 part of barium stearate, 0.2-0.3 part of dimethicone. 1-2 parts of carboxymethyl cellulose, 0.6-0.8 part of alumina, 1-3 parts of triphenyl phosphate, and 1-2 parts of distearoyl isopropoxy aluminate. 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 fire retardation, and can be used for fire retardation electric cable materials so as to reduce cost and improve various physical properties of the electric cable material.
Description
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 fire-resistant cable material.
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 heavy calcium carbonate and preparation method thereof for a kind of fire-resistant cable material.
The technical scheme of employing of the present invention is as follows:
A modified heavy calcium carbonate, is characterized in that, by the feed composition of following weight part, is prepared from:
Water-ground limestone 90-100, sodium butylnaphthalenesulfonate 0.2-0.5, polyoxyethylenated alcohol sodium sulfate 0.5-0.8, epoxidation tri-glyceride 1-2, stearic acid 0.1-0.2, barium stearate 0.1-0.2, dimethyl silicone oil 0.2-0.3, carboxymethyl cellulose 1-2, aluminum oxide 0.6-0.8, triphenylphosphate 1-3, sec.-propyl distearyl acyl-oxygen base Aluminate 1-2.
The preparation method of modified heavy calcium carbonate for described fire-resistant cable material, it is characterized in that: concrete operations are: water-ground limestone is dried to moisture content below 0.5% at 50-60 ℃ of temperature, then add in high-speed mixer, by formula rate, add successively sodium butylnaphthalenesulfonate, polyoxyethylenated alcohol sodium sulfate, epoxidation tri-glyceride, stearic acid, barium stearate, dimethyl silicone oil, carboxymethyl cellulose, aluminum oxide, triphenylphosphate, sec.-propyl distearyl acyl-oxygen base Aluminate and appropriate water, speed high-speed stirring 10-15 minute with 1200-1400 rev/min, then dry, grind to form nanometer powder, obtain modified calcium carbonate.
Beneficial effect of the present invention:
The present invention has added multiple dispersion 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 even, specific surface area is large, the modified calcium carbonate that application performance is better than ordinary calcium carbonate greatly, obtain 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 fire retardant, greatly improved the flame retardant properties of calcium carbonate, be applied in flame retarding PVC composition for cable production, can reduce the consumption of fire retardant, further reduce material cost, increase economic efficiency, improved mobility and the processing characteristics of system, and give goods good physical and mechanical properties, reach toughened and reinforced effect.
Embodiment
The preparation method of modified heavy calcium carbonate for a kind of fire-resistant cable material:
(kg) takes water-ground limestone 100, sodium butylnaphthalenesulfonate 0.4, polyoxyethylenated alcohol sodium sulfate 0.6, epoxidation tri-glyceride 1.5, stearic acid 0.2, barium stearate 0.1, dimethyl silicone oil 0.2, carboxymethyl cellulose 1, aluminum oxide 0.7, triphenylphosphate 2, sec.-propyl distearyl acyl-oxygen base Aluminate 1 by weight
Preparation method: water-ground limestone is dried to moisture content 0.4% at 55 ℃ of temperature, then add in high-speed mixer, by formula rate, add successively sodium butylnaphthalenesulfonate, polyoxyethylenated alcohol sodium sulfate, epoxidation tri-glyceride, stearic acid, barium stearate, dimethyl silicone oil, carboxymethyl cellulose, aluminum oxide, triphenylphosphate, sec.-propyl distearyl acyl-oxygen base Aluminate and 4-5kg water, with the speed high-speed stirring of 1200-1400 rev/min 15 minutes, then dry, grind to form nanometer powder, 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
The comparison of table 2 flexible PVC test piece test result
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.
