Table 11 below shows the Sabert cup (cup of the present invention) that obtains in embodiment 11 and the heat retaining property test result of polypropylene cup (prior art cup).As can be seen from Table 11, compared with the polypropylene cup of being made by PP H1500 resin, the heat-insulating property that the Sabert cup of being made up of the polypropylene resin composite in embodiment 1 is significantly improved.
Table 11 heat-insulating property
Table 12 below shows specific wear rate and the pollution resistance result of testing according to the testing method of describing in paragraph [0047].
Table 12: specific wear rate (wear resistance) and pollution resistance
| Cup | Specific wear rate | Pollution resistance |
| Polypropylene cup | 7.52x10 -6mm 3N -1m -1 | 16％ |
| Sabert cup | 6.63x10 -6mm 3N -1m -1 | 89％ |
Can find out from above-described embodiment 1-10, polypropylene resin composite according to the present invention has outstanding balance aspect hardness (wear rate or wear resistance), density and thermal conductivity.As shown in Example 11, polypropylene resin composite also has excellent antifouling property.
From above-described embodiment 11, can find out, the goods of being made up of polypropylene resin composite of the present invention have heat retaining property, wear resistance and the pollution resistance of raising.Fig. 3 shows the heat-insulating property curve of the cup (polypropylene cup) of being made up of plain polypropylene resin and the cup (Sabert cup) of being made up of neoteric resin combination.From Fig. 3 and table, can find out, after 30 minutes, heat retaining property can improve approximately 7.2 degrees Celsius.
According to the similar approach shown in embodiment 11, except omitting for the second time injection molded, the polypropylene resin composite in embodiment 2 is made to plate, as shown in Figure 2.In Fig. 2, resin layer 1 is used as skin and internal layer 2 is made by comprising polyacrylic glass sphere.Resin layer 1 accounts for the approximately 90wt% of plate and internal layer 2 and accounts for the approximately 10wt% of plate.Also made the similar plate with the resin layer that PP H1500 resin makes.Test-results shows, the plate of being made up of the polypropylene resin composite of the present invention in embodiment 2-10 has improved wear resistance, heat retaining property and antifouling property.
