To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of talcum powder master batch, by weight percentage,
Including following component：Polypropylene 19.6~20.4%, calcium stearate 0.1~0.9% and talcum powder 79.1~79.9%；Prepare
When, talcum powder is first put into, polypropylene is added, polyethylene and calcium stearate is then added, mixture banburying is heated up to 180
DEG C, heat 12 minutes, kneaded subsequently into double screw extruder, extrude, cool down and pelletizing after mixing.
It is preferred that, the polypropylene selects polypropylene S2040；The polypropylene S2040 boiling water boilings, it is high without damaging
Soften when warm and rigid inadequate, during low temperature, crack and embrittlement occurs in ductility.
It is preferred that, the talcum powder uses density for 2.8g/cm3；The HYT-04C model talcums of hardness Moh's scale number 1
Powder.
It is preferred that, the talcum powder includes：Silica 61.9%, magnesia 31.5%, calcium oxide 0.2%, three are aoxidized
The HYT-04C model talcum powder that two iron 0.20%, alundum (Al2O3) 0.2%, the loss on ignition 6% at 1050 DEG C are constituted.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
Talcum powder master batch of the present invention, due to the talcum powder of use its ultra-thin degree, ultrafine and uniform particle diameter point
Cloth, is well suited in terms of being used for modifying plastics, form, higher compound quantity due to its compacting, it is possible to increase the dispersiveness of plastics,
Wear-resisting, scratch-resistant, easy feeding, heat endurance is good.
Embodiment
With reference to specific embodiment, the present invention is described in further detail.
A kind of talcum powder master batch, by weight percentage, including following component：Polypropylene 19.6~20.4%, stearic acid
Calcium 0.1~0.9% and talcum powder 79.1~79.9%；During preparation, talcum powder is first put into, polypropylene is added, then adds
Polyethylene and calcium stearate, mixture banburying are heated up to 180 DEG C, heat 12 minutes, are kneaded subsequently into double screw extruder, mix
Extrude, cool down and pelletizing after refining.
The polypropylene selects polypropylene S2040；The polypropylene S2040 boiling water boilings, without damaging, soften during high temperature
And rigid inadequate, during low temperature, there is crack and embrittlement in ductility；At normal temperatures, than PE, ABS, PS is good, and especially temperature surpasses
When crossing 80 DEG C, it is numerous that its mechanical performance is unlikely to decline；During low temperature, very poor, the embrittlement that mechanical performance becomes；Film article：It is poly-
Polypropylene film product is transparent and glossy, and the permeability to water vapour and air is small, PP acid and alkali-resistances, resistance to numerous organic solvents, electricity
Insulating properties are good.Unique place maximum PP is that it has the gratifying resistance to tired property of flexing；It is active that polypropylene is produced
Hinge, can bear the folding flexing of hundreds of thousands time without damaging, blowing various small-scale vessel of hollow molding product etc.；PP's
Vertical and horizontal tensile strength difference is especially big, because this, has fine fibre forming property, is mutually fit to do fiber and rope；PP appearance
Hardness is unlike PS, ABS；But it is higher than PE and have good appearance gloss；Because this, it can do the production such as household appliances shell
Product.
It is preferred that, the talcum powder uses density for 2.8g/cm3；The HYT-04C model talcums of hardness Moh's scale number 1
Powder；The talcum powder includes：Silica 61.9%, magnesia 31.5%, calcium oxide 0.2%, di-iron trioxide 0.20%,
The HYT-04C model talcum powder that alundum (Al2O3) 0.2%, the loss on ignition 6% at 1050 DEG C are constituted；The HYT-04C models
Talcum powder measures median particle diameter D50 by sedigraph particle diameter distribution:0.75(1.0)*μm、 D95:2.5 μm, pass through laser particle size
Analyzer particle diameter distribution measures median particle diameter D50:3.5 (5)*μm、D95:7.0 μm, compacted volume density:0.55g/cm3, pine
Dissipate bulk density:0.11 g/cm3, the water content at 105 DEG C:0.2%；The HYT-04C is that high-purity whitens stone
Powder, due to its ultra-thin degree, ultrafine and uniform particle diameter distribution, whiteness is high, and good dispersion is wear-resisting, scratch-resistant, easy feeding, energy
The addition of remaining auxiliary agent is reduced, heat endurance is good, the reinforcing agent in terms of being well suited for for modifying plastics, due to the shape of its compacting
State, higher compound quantity, can as hemicrystalline high molecular polymer nucleator.
The talcum powder master batch are kneaded by double screw extruder, and the temperature of every section of twin-screw is respectively：T1=170 DEG C, T2
=175 DEG C, T3=175 DEG C, T4=175 DEG C, T5=175 DEG C, T6=180 DEG C, T7=180 DEG C, T8=180 DEG C, THead=180
DEG C, the tolerance of the temperature of every section of twin-screw is ± 5；Mixing of the reactant in double screw extruder, extrudes, cools down, cuts
Grain obtains talcum powder master batch.
Talcum powder master batch of the present invention, due to the talcum powder of use its ultra-thin degree, ultrafine and uniform particle diameter point
Cloth, is well suited in terms of being used for modifying plastics, form, higher compound quantity due to its compacting, it is possible to increase the dispersiveness of plastics,
Wear-resisting, scratch-resistant, easy feeding, heat endurance is good.
It the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way.It is all to use
