It is tested for the property sample is made after above-mentioned Polypropylene compositions composition granule heating melting, properties are shown in Table 1.
The preparation method of embodiment 2-4 and comparative example 1-5 are same as Example 1, dosage of each component and product
1 can be shown in Table.
Table 1:
Tensile strength and elongation at break use GB/T1040.2-2006/1A/50 standard testing, and impact strength uses GB/
T 1043-1993 standard testing, shore D hardness use GB/T 2411-1980 (15s) standard testing.
Through the foregoing embodiment with comparative example it is found that being existed using the product of the polypropene composition preparation in embodiment 1-4
While with excellent in toughness, shock resistance, there is high hardness, show that it, can be very with good scraping and wiping resistance performance
Good is used to prepare the auto parts and components such as backplate, cover plate；Composition in comparative example 1 is not the scope of the invention due to using
Interior polypropylene causes its shock resistance and hardness to reduce, and the composition in comparative example 2 is due to ethylene propylene copolymer and second
Alkene octene copolymer dosage is very few, causes its toughness and shock resistance to reduce, the composition in comparative example 3 is due to ethylene, propylene
Copolymer and ethylene octene copolymer dosage are excessively high, although its toughness is higher, its hardness is too low, the composition in comparative example 4,
Since amount of talc is very few, cause its hardness too low；Composition in comparative example 5, since amount of talc is excessive, although its
Hardness is high, but its toughness is obviously too low, is unsatisfactory for requiring.It can be seen that product prepared by the polypropene composition in comparative example 1-5 is not
Can have the toughness, shock resistance and scraping and wiping resistance performance of balance, lead to the performance for being not so good as product of the present invention in practical applications
It is excellent.
