Fig. 1 shows the cross section of Sabert cups.In Fig. 1, resin bed 1 is made up of the polypropylene resin composite in embodiment 1,
Outer layer 2 is made up of polypropylene, and optional internal layer 3 is made up of the glass marble for being mixed with thermoplastic.In cup, outer layer 2 accounts for
The about 11wt% of cup weight, and internal layer 3 accounts for the about 1wt% of glass weight.
The weight of Sabert cups is significantly higher than polypropylene cup.
According to above-mentioned method of testing, obtained cup is subjected to heat insulating ability, specific wear rate and pollution resistance experimental test.
Following table 11 shows the Sabert cups (cup of the present invention) obtained in embodiment 11 and polypropylene cup (existing skill
Art cup) heat insulating ability test result.As can be seen from Table 11, compared with the polypropylene cup made of PP H1500 resins, by reality
Apply the heat-insulating property that Sabert cups made of the polypropylene resin composite in example 1 are significantly improved.
The heat-insulating property of table 11
Following table 12 shows the specific wear rate and anti-soil tested according to the method for testing described in paragraph [0047]
Property result.
Table 12：Specific wear rate (wearability) and pollution resistance
| Cup | Specific wear rate | Pollution resistance |
| Polypropylene cup | 7.52x10-6mm3N-1m-1 | 16% |
| Sabert cups | 6.63x10-6mm3N-1m-1 | 89% |
From above-described embodiment 1-10 can be seen that according to the present invention polypropylene resin composite hardness (wear rate or
Wearability), there is outstanding balance in terms of density and thermal conductivity.As shown in Example 11, polypropylene resin composite also has
There is excellent antifouling property.
Product, which has, from above-described embodiment 11 as can be seen that made of the polypropylene resin composite of the present invention improves
Heat insulating ability, wearability and pollution resistance.Fig. 3 shows made of plain polypropylene resin cup (polypropylene cup) and by new invention
Resin combination made of cup (Sabert cups) heat-insulating property curve.From Fig. 3 and upper table as can be seen that at 30 minutes
Afterwards, heat insulating ability can improve about 7.2 degrees Celsius.
, will be poly- in embodiment 2 in addition to omitting second of injection molded according to the similar approach shown in embodiment 11
Plate has been made in propylene resin composition, as shown in Figure 2.In Fig. 2, resin bed 1 is used as outer layer and internal layer 3 is by comprising poly-
The glass marble of propylene is made.Resin bed 1 accounts for the about 90wt% of plate and internal layer 3 accounts for the about 10wt% of plate.Also being made has
The similar plate of resin bed made of PP H1500 resins.Result of the test shows, by of the invention poly- third in embodiment 2-10
Plate made of olefine resin composition has improved wearability, heat insulating ability and antifouling property.
