performance test
The ABS regrind prepared from examples 1-5 and comparative examples 1-8 was sampled and the samples were subjected to the following property testing tests.
And (3) testing the ageing resistance: and (3) placing the samples in an aging test box, carrying out ultraviolet concentrated irradiation, and recording the aging time of each group of runway samples.
And (3) testing tensile property: the tensile strength of the sample is measured, typically by tensile measurement of the solid material using a universal electronic tester.
TABLE 1 results of physical and chemical properties of samples
According to the results of the physical and chemical property tests of the samples in examples 1-3, it can be seen that: the ABS regrind has good aging resistance and tensile strength, but the proportion of each component in example 1 is the best example in three groups of examples.
According to the results of the physical and chemical property tests of the samples in example 1 and comparative examples 1 to 4, it can be seen that:
the benzyl-viscose fiber has obvious promotion effect on improving the ageing resistance of the ABS reclaimed material and also has certain promotion effect on improving the tensile strength of the ABS reclaimed material;
the benzyl is adopted to modify the viscose, so that the anti-aging performance of the ABS reclaimed material is improved, but the influence on the tensile strength of the ABS reclaimed material is small;
the nano titanium dioxide has obvious promotion effect on improving the ageing resistance and the tensile property of the ABS reclaimed material; the methyl silicone is beneficial to improving the ageing resistance of the ABS reclaimed material, but has little influence on the tensile strength of the ABS reclaimed material.
According to the results of the physical and chemical property tests of the samples in example 1 and comparative examples 5-6, it can be seen that:
the EVA is adopted to modify the ABS reclaimed material, which is beneficial to improving the tensile strength of the ABS reclaimed material;
the nano calcium carbonate is beneficial to improving the tensile strength of the ABS reclaimed material.
According to the results of the physical and chemical property tests of the samples in examples 1, 4-5 and comparative examples 7-8, it can be seen that: in the process of modifying the ABS resin, the ratio of the ABS resin, the benzyl-viscose fiber, the nano titanium dioxide and the methyl silicone is changed to have a certain influence on the tensile strength of the ABS reclaimed material, so the ratio of the four should be controlled within a proper range.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
