Description
Technical field
The present invention relates to material modified technical field, and in particular to a kind of low gloss, damage resistant, high impact resistance polypropylene combination
Thing and preparation method thereof.
Background technology
Polypropylene (PP) material extensively should be obtained due to its good combination property in the major assembly systems of automobile
With.Automobile exterior trimming parts are used mostly PP composite material injection moulding with inside gadget.Exterior trimming parts such as bumper, threshold, shirt rim
Deng, automotive upholstery such as instrument board, column, glove compartment, door-plate etc., automotive interior material except with good mechanical property,
Outside processing characteristics, weather resistance, in addition it is also necessary to good outward appearance, by reducing interior trim glossiness and improving damage resistant, can not only reach
To the requirement of good appearance, while may also reach up the effect of environmental protection and energy saving by MIC techniques (MOLD IN COLOR).
A kind of preparation of damage resistant PP compositions is described in patent No. CN102532719A, its method is that addition one kind is received
Rice scraping-resistant agent (nano aluminium oxide, nano silicon oxide, the nano zine oxide compound of one or more), its shortcoming is prepared material
The PP impacts of material are relatively low, and nanometer scraping-resistant agent addition is a lot, relatively costly.
Low gloss damage resistant, the preparation of high-impact PP compositions are described in patent No. CN103030876A, its method is
Addition glass master batch, it has the disadvantage to a certain degree influence the outward appearance of its product after adding glass.
Improving the method for damage resistant by reducing skin-friction coefficient has addition silicone and erucyl amide.The damage resistant of silicone
Excellent performance, but silicone has certain smell；Erucyl amide addition has a cost advantage less, but erucic acid smell it is very big and
Do not separated out seriously after heatproof, especially weatherable, article surface is tacky.
The content of the invention
It is an object of the invention to provide a kind of low gloss, damage resistant, high-impact PP compositions.
The technical solution used in the present invention is：
A kind of low gloss, damage resistant, the preparation of high-impact PP compositions, it is made up of the raw material of following mass parts：45-60
Impact modifier, the 15-25 parts of talcum powder of PP, 10-25 part of part, 5-10 parts of low gloss agent, 1-3 parts of damage resistant agent, 0.5-
2.0 parts of damage resistant synergists, 0.1-0.5 parts of antioxidant.
Preferably, described damage resistant agent is low-molecular-weight (molecular weight 600-1000) polyethylene (PE) wax, low-molecular-weight
PE waxes can reduce the coefficient of friction of material surface, while contributing to pigment and filler dispersed in PP matrixes, change
Kind filler and the interface energy of PP matrixes, improve the damage resistant of material.
Preferably, described damage resistant synergist is middle-molecular-weihydroxyethyl (molecular weight 350-500) antistatic additive, and antistatic additive is moved
Move to component surface and form moisture film, assist damage resistant agent low-molecular-weight PE waxes to improve its skin-friction coefficient, improve damage resistant；If
Using low-molecular-weight antistatic additive, its synergistic damage resistant long-term effect is poor, and HMW antistatic additive, its migration velocity compared with
Slowly, the damage resistant synergistic of early stage is poor.
Preferably, described low gloss PP, is copolymerization PP of its C2 content in 48~55mol%, melt flow rate (MFR)
(MFR) 20~60g/10min of scope.
Preferably, low gloss agent is ethylene propylene diene rubber (EPDM) master batch, and the addition of EPDM can effectively reduce its combination
Thing glossiness.
Preferably, described impact modifier includes the one kind in 4 carbon poly olefin elastomers (POE), 8 carbon POE.
Preferably, described antioxidant is 1010,168.
A kind of low gloss, damage resistant, the preparation method of high impact resistance polypropylene composition, comprise the following steps：
(1) 5-10 parts of polypropylene of the low gloss agent with 45-60 parts is blended in proportion, is made in addition double screw extruder
Master batch；
(2) by 10-25 parts of impact modifier, 15-25 parts of talcum powder, 1-3 parts of damage resistant agent, 0.5-2.0 parts it is scratch-resistant
Hinder synergist and 0.1-0.5 parts of antioxidant adds high-speed mixer and mixing, then the master batch that will be prepared to be added in mixture, pass through
Double screw extruder mixing, extrusion.
EPDM molecular weight is of a relatively high, and it is difficult to evenly spread in PP matrixes, it is difficult to obtain the good product of outward appearance；Mirror
It is difficult to disperse in EPDM, therefore EPDM is first made master batch with the low gloss PP blendings of C2 contents high in the present invention, then by mother
Grain is added in PP compositions by a certain percentage.
Preferably, the technological parameter of the double screw extruder is：1 180~200 DEG C of area, 2 180~210 DEG C of areas, 3rd area
180~210 DEG C, 4 180~210 DEG C of areas, 5 180~210 DEG C of areas, 6 180~210 DEG C of areas, 7 180~210 DEG C of areas, 8 areas 210~
230 DEG C, 9 210~250 DEG C of areas, 10 210~250 DEG C of areas, 200~230 DEG C of head temperature, head pressure 3.8Mpa, main frame electric current
30Hz, vacuum -0.06MPa.
Compared with prior art, the present invention has the advantages that：
Improve scratch resistant performance compared to methods such as prior art addition silicone, erucyl amide, glass master batches, the present invention has
The defect of the high cost for avoiding silicone of effect, the precipitation of being heated of erucyl amide, and the poor outward appearance of glass master batch, the present invention passes through
Use low-molecular-weight PE waxes and middle-molecular-weihydroxyethyl antistatic additive, the scratch resistant performance except effectively improving PP compositions, while tool
Standby low smell, low VOC, without separating out the advantages of, the present invention is resistance to by low-molecular-weight PE waxes and middle-molecular-weihydroxyethyl antistatic additive compounding use
Scratch performance to significantly improve, although PE waxes and antistatic additive can reduce the coefficient of friction on PP compositions surface, both are single
Solely when using, its scratch resistant performance is not protruded, and reduction can be just played because antistatic additive needs to move to composition PP surfaces
The effect of friction, therefore when both compounding uses, PE waxes are lubricated the intermolecular frictional force of reduction to intramolecular, make molecule
Between space increase to be formed " molecular channel ", the antistatic additive of middle-molecular-weihydroxyethyl can by " molecular channel " can fast transferring to composition
Surface, plays a part of quick outer lubrication；So during both compound uses, the efficiency of damage resistant is greatly improved.
Compared to existing other inventions, directly using EPDM reduce gloss degree, it has the shortcomings that poor outward appearance, of the invention by EPDM
Low gloss copolymerization PP with C2 contents high is first prepared into master batch by twin-screw extrusion, then master batch is added to PP combinations in proportion
In thing, its EPDM is uniformly dispersed, and the product outward appearance being molded is good and glossiness is low.
