Abstract
The invention belongs to the technical field of composite materials and in particular relates to a nano polypropylene composite material. The nano polypropylene composite material is obtained by mixing 80 to 120 parts of polypropylene, 10 to 25 parts of nano calcium carbonate and 30 to 50 parts of heavy calcium carbonate, uniformly stirring the components and extruding by using a dual screw granulation extruder. By adoption of the mode of mixing the nano calcium carbonate and the heavy calcium carbonate, the cost is reduced, the defect of filling of the polypropylene by independently using the nano calcium carbonate and the heavy calcium carbonate is overcome, and the surface performance of the composite polypropylene material is improved effectively on the basis of keeping good physical mechanical performance.
Description
Technical field
The invention belongs to technical field of composite materials, be specifically related to a kind of nano-polypropylene composite material.
Background technology
The additive that polypropylene composite material adopts usually has water-ground limestone and nano-calcium carbonate, and both respectively have relative merits.
Water-ground limestone not only cost is low but also can improve the resistance to impact shock of polypropylene composite material, but water-ground limestone is when adding polypropylene composite material to, tends to the surface property of impact polypropylene matrix material, the phenomenon of turning white in the surface occurs as meeting.
Though nano-calcium carbonate cost height, it can improve polyacrylic resistance to impact shock, improves the polypropylene surface performance, as improves glossiness and improve scratch resistance performance etc., so nano-calcium carbonate is through being often used as the additive of polypropylene composite material.As application number is that 01108269 Chinese invention patent has been introduced a kind of nanometer calcium carbonate-polypropylene composite material and preparation method thereof, and it mainly is made up of polypropylene, wherein contains the nanometer CaCO of 0.25-30% (m/m)
3Application number is that 200610156323 Chinese invention patent discloses a kind of nanometer calcium carbonate polypropylene composite material, and this matrix material comprises 100 parts of acrylic resins, 1-15 part nano-calcium carbonate, 1-20 part elastomerics, 0.1-1 part stablizer.
But result of study shows the increase along with the nano-calcium carbonate addition, and the resistance to impact shock of polypropylene composite material increases earlier, reduces then.This is because along with the increase of the addition of nano-calcium carbonate makes that the agglomeration of nano-calcium carbonate self is more and more serious, and then causes the resistance to impact shock of polypropylene composite material to reduce.For to polypropylene composite material in the consideration aspect the resistance to impact shock, the addition of nano-calcium carbonate is subjected to certain restriction, so because the surface property that has limited the addition polypropylene composite material of nano-calcium carbonate can not get effective improvement.
Summary of the invention
The purpose of this invention is to provide a kind of cost low, can keep good physical and mechanical properties can improve the nano-polypropylene composite material of polypropylene material surface property again.
The object of the present invention is achieved like this:
A kind of nano-polypropylene composite material, it comprises the raw material of following weight part:
Polypropylene 80-120 part
Nano-calcium carbonate 10-25 part
Water-ground limestone 30-50 part.
Preferably, it comprises the raw material of following weight part:
Polypropylene 90-110 part
Nano-calcium carbonate 15-25 part
Water-ground limestone 35-45 part.
More preferred, it comprises the raw material of following weight part:
100 parts of polypropylene
20 parts of nano-calcium carbonates
40 parts of water-ground limestones.
The particle diameter of described nano-calcium carbonate is the 50-150 nanometer.
The particle diameter of described water-ground limestone is the 2000-2500 order.
Described nano-polypropylene composite material also comprises auxiliary agent.
Nano-polypropylene composite material also comprises auxiliary agent, described auxiliary agent is a kind of or several arbitrarily in softening agent, thermo-stabilizer, oxidation inhibitor, photostabilizer, fire retardant, whipping agent, static inhibitor, mould inhibitor, the tinting material, can be as required routinely addition add.
The preparation method of described nano-polypropylene composite material is the raw material mixing with above-mentioned formula ratio, and the back that stirs is squeezed machine by the twin screw granulation and extruded.
The temperature of leading portion, stage casing and back segment was respectively 200 ℃, 210 ℃, 190 ℃ when the machine extruding pelletization was squeezed in described twin screw granulation.
Beneficial effect of the present invention is: the present invention utilizes the little quality and the high surface energy of nano-calcium carbonate, makes nano-calcium carbonate attached to the water-ground limestone surface, form nuclear the composite structure of shell.In mixing process, nano-calcium carbonate along with water-ground limestone moves together, has effectively been avoided the agglomeration of nano-calcium carbonate attached to the surface of water-ground limestone; In addition because nano-calcium carbonate has high surface energy, it is tightr with combining of polypropylene macromolecular chain, therefore water-ground limestone can be by combining with the polypropylene macromolecular chain attached to its surperficial nano-calcium carbonate, make that the polypropylene composite material surface is more smooth, luster performance is better, and surperficial scratch resistance ability is stronger; Will not be filled into the various gaps of polypropylene composite material, show the various advantages of nano material attached to the nano-calcium carbonate on water-ground limestone surface.The mode that the present invention adopts nano-calcium carbonate and water-ground limestone to combine, reduced cost, overcome the shortcoming of independent use water-ground limestone and nano-calcium carbonate filled polypropylene, on the basis that keeps the good physical mechanical property, effectively improved the surface property of polypropylene composite material.
