Control experimental group 1:
the method is used for comparing the influence of the addition of different fine glass fibers on the performance of the final PC/PBT alloy material;
wherein, the preparation steps and components of the examples 2 to 10 and the comparative examples 1 and 2 are the same as those of the example 1, and the specific contents of the components of the examples and the comparative examples are shown in the table 1; the PC/PBT alloy materials prepared in the examples 2 to 10 and the comparative examples 1 and 2 are subjected to corresponding experimental tests as in the example 1, and the test data are shown in Table 2.
TABLE 1 examples and comparative component contents
Table 2 examples and comparative experimental data
From a comparison of table 1 with table 2, it can be seen that:
1. comparing examples 1 to 4 with example 10 and comparing examples 5 to 8 with example 9, wherein, only the content of the fine glass fiber is changed, and the comparison of the examples shows that the ball indentation hardness, the PV3987 wear-resistant gloss retention rate, the pencil hardness and the tensile strength of the final PC/PBT alloy material are gradually increased along with the increase of the content of the fine glass fiber, the notch impact strength is reduced, therefore, the scratch resistance and hardness of the finally modified PC/PBT alloy material are increased along with the increase of the content of the fine glass fiber within the range of 0.5-5, when the content of the fine glass fiber is 5 parts, the performance is best, when the content of the fine glass fiber is more than 5 parts, the gloss of the glossy color plate at 20 ℃ is reduced too much, and the high gloss performance can no longer be maintained, and therefore, the preferable range of the fine glass fiber is 0.5 to 5.
2. Comparing examples 1-4 with comparative example 1, and comparing examples 5-8 with comparative example 2, and comparing the difference between the PC/PBT alloy material without adding fine glass fiber and the PC/PBT alloy material of the invention, wherein the 20 DEG Gloss (GU) of the smooth color plate of comparative example 1 and comparative example 2 is higher than the 20 DEG Gloss (GU) of the smooth color plate of examples 1-8, so that it can be known that adding fine glass fiber modifies the PC/PBT alloy material, has a slight influence on the gloss, but has a small influence range according to the data of phase difference, and can also keep the high gloss performance; the data of ball indentation hardness, PV3987 abrasion resistant gloss retention, pencil hardness and tensile strength of comparative example 1 and comparative example 2 are significantly lower than those of examples 1 to 8, and thus it is known that the addition of the fine glass fiber can effectively improve the hardness and scratch resistance of the PC/PBT alloy material, so that the PC/PBT alloy material has high hardness and high scratch resistance.
Control experimental group 2:
the method is used for comparing the influence of fine glass fibers with different diameters on the performance of the final PC/PBT alloy material;
the preparation steps and the component contents of the examples 11 to 14 are the same as those of the example 4, except that the diameters of the filaments of the fine glass fibers are shown in table 3; the PC/PBT alloy materials prepared in the examples 11 to 14 are tested in an experiment, and the test data are compared with the data of the example 4, so that the test results shown in the following Table 3 can be obtained:
table 3 component contents and test data of examples 11 to 14
Comparing example 4 with examples 11 to 14, the data of ball indentation hardness, PV3987 abrasion resistant gloss retention and tensile strength of examples 11 to 14 are all smaller than those of example 4, so that the modification effect on the PC/PBT alloy material is poorer as the diameter of the fine glass fiber monofilament is increased, and especially when the diameter of the fine glass fiber monofilament is more than 15 μm, the 20 DEG gloss effect of the PC/PBT smooth panel is influenced, and the highlight effect is influenced; it can be seen that the smaller the monofilament diameter of the fine glass fiber added, the better the modification effect on the PC/PBT alloy material, and when the monofilament diameter is 7 μm, the hardness and scratch resistance of the PC/PBT alloy material are the best. At present, fine glass fibers with the monofilament diameter of less than 7 mu m do not appear on the market, so the fine glass fibers have the best effect when the monofilament diameter is 7 mu m.
Control experimental group 3:
under the condition that the content of the fine glass fibers is consistent with the diameter, the influence of the content of other components on the performance of the final PC/PBT alloy material is compared;
wherein, the preparation steps of the examples 15 to 19 are consistent with those of the example 4, and the specific contents are shown in the table 4; the PC/PBT alloy materials prepared in the examples 15 to 19 are tested in an experiment, and the test data are compared with the data of the example 4, so that the test results shown in the table 5 can be obtained:
table 4 component contents of examples 15 to 19 and example 4
Table 5 experimental data for examples 15 to 19 and example 4
As can be seen from the data in tables 4 and 5, the performance of the final PC/PBT alloy material is not greatly affected by changing the compatibilizer, antioxidant, UV absorber, and lubricant.
Control experimental group 4:
the method is used for comparing the influence of PC with different melting fingers on the performance of the final PC/PBT alloy material;
the preparation steps and the component contents of examples 20 to 23 are the same as those of example 4, except that the melt index of PC is different, and the specific melt index values are shown in Table 6; the PC/PBT alloy materials prepared in the examples 20 to 23 are tested in an experiment, and the test data are compared with the data of the example 4, so that the test results shown in the table 6 can be obtained:
TABLE 6 PC melt index values and test results for examples 20 to 23
As can be seen from the data in Table 6, the different melt index ranges of PC have no great influence on the performance of the final PC/PBT alloy material, and the conventional melt index range of 10-20g/min is selected.
Control experimental group 5:
the impact of PBT with different viscosities on the performance of the final PC/PBT alloy material is compared;
the preparation steps and the component contents of the examples 24 to 27 are the same as those of the example 4, except that the viscosity of the PBT is different, and the specific contents are shown in Table 7; the PC/PBT alloy materials prepared in the examples 24 to 27 are tested in an experiment, and the test data are compared with the data of the example 4, so that the test results shown in the table 7 can be obtained:
TABLE 7 viscosity and test results for PBT of examples 24 to 27 and example 4
| Components | Example 4 | Example 24 | Example 25 | Example 26 | Example 27 |
