Performance test
The PC-ABS sheets prepared in the application examples 1 to 7 and the application comparative examples 1 to 3 are subjected to tensile strength, bending property, notched izod impact strength and stress cracking tests.
Detection method/test method
Tensile strength: according to ISO527 standard.
Bending property: according to ISO178 standard.
Cantilever notch impact strength: according to ISO179 standard.
Stress cracking test: the sample strips are stretched and soaked in glacial acetic acid for 3min to see the cracking condition of the sample strips, and the samples are visually observed.

By combining application examples 1-7 and application comparative examples 1-3 and combining table 2, the values of tensile strength, bending property and cantilever beam notch impact strength of the PC-ABS sheets of the application examples 1-7 are higher than those of the PC-ABS sheets of the application comparative examples 1-2, so that the master batch can greatly improve the fluidity between PC and ABS, further improve the dispersion uniformity of PC and ABS, and improve the performances of the PC-ABS sheets, such as rigidity, bending and strength. The PC-ABS sheets prepared in application examples 1-7 have no cracking phenomenon, while the PC-ABS sheet prepared in comparative example 1 has the cracking phenomenon, which shows that the possibility of cracking of the PC-ABS sheets can be effectively reduced by using the master batch.
The values of the tensile strength, the bending property and the cantilever beam notch impact strength of the PC-ABS sheet prepared by using the master batch in application example 5 are higher than those of the PC-ABS sheet prepared by using the common master batch in application comparative example 3, which shows that the PC and the ABS have better tensile strength, bending property and cantilever beam notch impact strength in the application range.
As can be seen by combining application examples 2-4 and application examples 5-7 with Table 2, the values of tensile strength, bending property and cantilever beam notched impact strength of the PC-ABS sheets of application examples 2-4 are higher than those of the PC-ABS sheets of application examples 5-7, which indicates that the master batch prepared by using the activated calcium carbonate of the application has better tensile strength, bending property and cantilever beam notched impact strength for preparing the PC-ABS sheets.
