Description
Technical field
The invention belongs to field of polymer composite material, and in particular to a kind of improving floats fine fiber glass reinforced polypropylene composition and preparation method thereof.
Background technology
Polypropylene is the highly crystalline polymer of nontoxic, odorless, tasteless milky, molecular weight about 80,000-15 ten thousand, and density only has 0. 90-0. 91g/cm3, it is one of most light kind in current all plastics.In addition, polypropylene is particularly stable to water, the water absorption rate in water is only 0. 01%.Polypropylene is good, but because its shrinkage factor is big, about 1% ~ 2.5%, so being made thick article depression easily occurs, therefore to some dimensional accuracies part higher, it is difficult to reach requirement.
It is main at present to improve intensity, heat distortion temperature and the dimensional stability of polypropylene material by adding glass fiber reinforced polypropylene, the application field of polypropylene material is expanded, it is widely used in the fields such as electronic apparatus, automobile, building.
But then easily occur floating fine phenomenon after adding glass, floating fibre phenomenon is usually to be caused by glass emergence on the surface, white glass is floated during plastic melt filling flow and is exposed to appearance, radial white vestige just is formed on plastic surface after shaping to be condensed, can be more obvious because shade deviation is increased when plastic is for black.So floating fibre phenomenon not only influences the cosmetic look of PA products, its performance as resistance to rolled-up stock is had an effect on.
The content of the invention
It is an object of the invention to provide a kind of fiber glass reinforced polypropylene composition for improving and floating fibre and preparation method thereof.

The nucleator is Sodium Benzoate.
Present invention also offers a kind of above-mentioned preparation method for improving the fiber glass reinforced polypropylene composition for floating fibre, the method is comprised the following steps：
（1）Polypropylene and polyethylene are dried respectively；
（2）By proportioning, by dried polypropylene, polyethylene, glass fibre, mica, toughener, nucleator and silicone powder, 3-5min is stirred in addition high-speed mixer；
（3）Well mixed material is added from the charge door of double screw extruder, through double screw extruder melting extrusion, granulation, the fiber glass reinforced polypropylene composition for improving and floating fibre is prepared into.
Described dry polypropylene be temperature be 50-80 DEG C, dry 4-5h；Polyethylene dries 4-5h in 50-80 DEG C of temperature.
The processing technology of described double screw extruder is：160-170 DEG C of the area's temperature of double screw extruder one, two 165-175 DEG C of area's temperature, three 180-190 DEG C of area's temperature, four 195-205 DEG C of area's temperature, five 195-205 DEG C of area's temperature, six 200-210 DEG C of area's temperature, 200-210 DEG C of head temperature, engine speed is 15-35HZ.
The present invention compared with the existing technology, has the advantages that：
1st, the present invention adds mica and silicone powder to enhance the compatibility between polypropylene and glass fibre, and crosslinking points are formed between glass fibre, acrylic resin, improves the bond state of glass and resin, reduces glass and is separated with resin.Meanwhile, cooperated between mica and silicone powder, the dispersiveness of glass fibre is improve, increase polypropylene and glass fibre interface compatibility, reduce glass and separated with resin, so as to greatly reduce exposing for glass.
2nd, because the mechanical function thickness degree between the surface of glass and matrix resin increases, the matrix in glass near surface is easier to shear yielding, increase the absorption to impact energy and dissipative effect, promote glass to the toughening effect between matrix resin.So that glass is coated well in resin, glass flowing synchronous with resin, is difficult to rip in process, greatly reduces exposing for glass.
3rd, mica and silicone powder reduce glass emergence on the surface, so as to correspondingly reduce the friction of glass and screw rod, the moment of torsion of screw rod is also decreased, it is easy to process.
4th, modified fiberglass reinforced PET composition prepared by the present invention has excellent mechanical property.
