Description
Technical field
The present invention relates to the technical fields of composite material, and in particular to a kind of preparation method of modified polypropylene material and its
Product.
Background technology
Polypropylene is as a kind of general-purpose plastics material, since it is low with good comprehensive performance, processing performance and price
It is honest and clean, therefore had a wide range of applications in fields such as automobile, household electrical appliances, packaging, buildings.But there is also easy to aging, toughness for polypropylene
The shortcomings of poor, low temperature resistant notch impact strength is relatively low, inprocess shrinkage is larger.The height of material property is wanted in order to meet people
It asks, processing need to be modified to polypropylene, to widen polyacrylic purposes and practical application,
Invention content
In view of the deficiencies of the prior art, a kind of modified polypropylene material of present invention offer and preparation method thereof, it is prepared
Modified polypropene has good low-temperature impact-resistant intensity.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of modified polypropylene material and preparation method thereof, which is characterized in that modified polypropylene material of the invention be by
The raw material of following parts by weight forms：Polypropylene 50~90, PFA resins 6~15, solubilizer 2~10, ethylene bis stearic acid amide
0.2~1.0, nucleating agent 0.2~0.6.
Preferably, modified polypropylene material, is made of the raw material of following parts by weight：Polypropylene 65~80, PFA resins 6
~15, solubilizer 4~7, ethylene bis stearic acid amide 0.3~0.6, nucleating agent 0.25~0.4.
The solubilizer is perfluor alkyl ethide methacrylate grafted high density polyethylene.
Other auxiliary agents of 0.2~0.8 parts by weight are additionally added in the modified polypropene, other described auxiliary agents include antioxygen
Agent, colorant, weather resisting agent.
A kind of modified polypropylene material, preparation method include the following steps：First by polypropylene and compatilizer
Uniform mixed melting, extruding pelletization, obtain batch mixing A；Then, by batch mixing A, PFA resin and other remaining auxiliary agents, uniformly mixing is molten
Melt, extruding pelletization to get.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention realizes toughening modifying, and the excellent specific property of comprehensive PFA resins, significantly carries by introducing PFA resins
The mechanical strength of polypropylene material, resistant to chemical etching, heat-proof aging are risen, product service life is improved.
(2) present invention introduces perfluor alkyl ethide methacrylate grafted high density polyethylene (TFE-g- simultaneously
HDPE), the graft of one side TFE-HDPE can form strong attraction with PFA resins；Meanwhile HDPE also can with it is poly-
Propylene molecules chain forms good entanglement and compatible, and then is effectively improved the interface cohesion of polypropylene and PFA resins, avoids the occurrence of
Lamination；On the other hand, it is generated using nucleating agent induction crazing, stress is promoted to disperse.The two improves modified polypropene jointly
Low-temperature impact-resistant performance.
(3) preparation process provided by the invention is simple, and operability is strong, is conducive to factory scale production.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
The every other embodiment that technical staff is obtained without creative efforts belongs to the model that the present invention protects
It encloses.
Each raw material (parts by weight), extruding pelletization and injection molding are weighed according to the formula of each embodiment of the following table 1, is modified
Polypropylene.
The parts by weight of modified polypropene in 1 each embodiment and comparative example of table
Modified polypropene prepared by each embodiment and comparative example is tested for the property, the results detailed in Table 2.Wherein, it adopts
The tensile strength of material is tested with ISO 527；The notch impact strength of material is surveyed using ISO 519/1eA
Examination.
The mechanical property of modified polypropene prepared by 2 each embodiment and comparative example of table
| Number | Tensile strength/MPa | Notch impact strength/KJ/m2 |
| Embodiment 1 | 30 | 25 |
| Embodiment 2 | 31 | 27 |
| Embodiment 3 | 33 | 27 |
| Embodiment 4 | 37 | 30 |
| Embodiment 5 | 34 | 28 |
| Embodiment 6 | 35 | 27 |
| Comparative example 1 | 13 | 10 |
| Comparative example 2 | 32 | 26 |
| Comparative example 3 | 26 | 24 |
As shown in Table 2, relative to comparative example 1-3, had by the modified polypropene prepared by embodiment 1-6 and more preferably stretched
Intensity and notch impact strength.Thus explanation is by introducing a certain amount of perfluor alkyl ethide methacrylate grafted high density
Polyethylene (TFE-g-HDPE) can be used as interface solubilizer, significantly improve the two-phase interface of polypropylene and PFA resins, avoid out
Existing two phase stratification phenomenon.Comparative example 1 and embodiment 4 more illustrate that TFE-g-HDPE can be effectively improved the low temperature notched punching of material
Hit intensity and tensile strength.Meanwhile the result of comparative example 3 and embodiment 4 illustrates, nucleating agent is added can also be promoted to a certain degree
The performance of material.
