Described lubricant be calcium stearate, Tissuemat E, ethylene bis stearamide (EBS) and one kind in silicone or
The two or more mixture of person.
Described mould inhibitor is commercially available plastic mould-proof agent.
Described compatilizer is maleic anhydride inoculated polypropylene (PP-G).
The preparation method of the mould proof fiber glass reinforced polypropylene material of above-mentioned low-temperature impact-resistant, comprises the following steps：
1) polypropylene, toughener, antioxidant, lubricant, compatilizer and mould inhibitor are weighed by weight, in high mixer
Mix 5-10 minutes；
2) above-mentioned mixed material is added into double screw extruder and carries out melting mixing, glass fibre is added by side feeding
Enter, by extrusion, the mould proof fiber glass reinforced polypropylene material of cooling, pelletizing, the low-temperature impact-resistant of the drying to obtain present invention.
The invention has the advantages that compared with prior art, the mould proof glass of low-temperature impact-resistant prepared by the present invention
RPP material has good low-temperature flexibility and anti-mold effect, can be used in fields such as household electrical appliances, automobile, communications.
Embodiment
With reference to embodiment, the present invention is further elaborated：
Table 1：The mould proof fiber glass reinforced polypropylene material formula table of low-temperature impact-resistant
The preparation method of embodiment and comparative example：1) polypropylene, toughener, antioxidant, lubricant, phase are weighed by weight
Hold agent and mould inhibitor, high-speed mixer and mixing 5-10 minutes；2) above-mentioned mixed material is added into double screw extruder to be melted
Melt mixing, glass fibre is added by side feeding, by extrusion, cooling, pelletizing, the low-temperature impact-resistant of the drying to obtain present invention
Mould proof fiber glass reinforced polypropylene material.3) sample preparation is molded, gained batten, model (disk) are tested, test condition
It is as follows：Tensile strength and notch shock are tested at 23 DEG C；Tested after placing 4H at -30 DEG C of low temperature ball falling impact；
The standard of fungus-proof test is ASTM G21, as a result as shown in table 2：
Table 2：The performance test results (ISO) of the mould proof fiber glass reinforced polypropylene material of low-temperature impact-resistant
| Performance | Unit | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 | Comparative example 1 |
| Tensile strength | MPa | 70 | 68 | 72 | 60 | 55 | 88 |
| Notch shock | KJ/m2 | 20 | 23 | 21 | 23 | 18 | 11 |
