The preparation method of the polycarbonate/polyethylene terephthalate-1, 4-cyclohexanedimethanol ester alloy material of the comparative example is the same as that of the example 1, and therefore, the detailed description is omitted.
Comparative example 4
In this comparative example, a polycarbonate/polyethylene terephthalate-1, 4-cyclohexanedimethanol ester alloy material, in weight percent, comprises: 69% of the polycarbonate, 30% of the polyethylene terephthalate-1, 4-cyclohexanedimethanol ester, 0.2% of a main antioxidant, 0.2% of an auxiliary antioxidant, 0.3% of the light stabilizer and 0.3% of a lubricant.
The preparation method of the polycarbonate/polyethylene terephthalate-1, 4-cyclohexanedimethanol ester alloy material of the comparative example is the same as that of the example 1, and therefore, the detailed description is omitted.
Pellets obtained in examples 1 to 5 and comparative examples 1 to 4 were molded on an injection molding machine to prepare test specimens of 120X 13X 1.6mm for performance testing, and the test results are shown in Table 1:
TABLE 1 results of physical Properties test of examples 1 to 5 and comparative examples 1 to 4
Wherein:
more + indicates better solvent resistance, -indicates solvent intolerance
+ + + + + + + + + + -represents no change in splines
+ represents a slight crack
+ denotes the presence of a crack
Breaking of the sample strip
As can be seen from Table 1, the solvent resistance was poor when PCTG was not added to the raw materials for the production of the polycarbonate/polyethylene terephthalate-1, 4-cyclohexanedimethanol ester alloy material. The introduction of PCTG can effectively improve the solvent resistance of the polycarbonate/polyethylene terephthalate-1, 4-cyclohexane dimethanol ester alloy material. However, if polyolefin grafted acrylate and polystyrene grafted maleic anhydride are not added, the notch impact strength of the PC alloy material is reduced rapidly, and the single polyolefin grafted acrylate or polystyrene grafted maleic anhydride is introduced, so that the notch impact strength is not obviously improved. It can also be seen from table 1 that when the polycarbonate/polyethylene terephthalate-1, 4-cyclohexanedimethanol ester alloy material is introduced with polyolefin grafted acrylate and polystyrene grafted maleic anhydride, the solvent resistance and the notched impact strength of the PC alloy material can be significantly improved. The reason is that: the polyolefin grafted acrylate can form a sea-island structure in the alloy, the polyolefin section is taken as the core to provide excellent impact resistance for the alloy material, and the acrylate section is taken as the shell to form an excellent compatible interface with the base material; in the polystyrene grafted maleic anhydride, a polystyrene segment can form a physical entanglement point with polycarbonate and poly (1, 4-cyclohexanedimethanol terephthalate), and a maleic anhydride active group can react with a terminal hydroxyl group in a polymer, so that the polyolefin grafted acrylate and a base material have higher-strength interface bonding force, and a function of stopping crack propagation is achieved in the process of material damage, and therefore, the notch impact strength of the alloy is improved through the combined action of the polyolefin grafted acrylate and the polystyrene grafted maleic anhydride.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the best embodiments, the present invention is not limited to the above disclosed embodiments, but should cover various modifications, equivalent combinations, made according to the essence of the present invention.
