TABLE 6 test results
Because of different enterprises and institutions, the injection mold and the injection process of the test sample bar are different, so that the test result is different, and the patent only compares the difference and the test data is not absolute.
As can be seen from comparison cases 1 and 2, the ABS-PCR material has lower mechanical properties than the ABS resin, wherein the impact property is less than half of that of the whole new material; ABS-PCR cannot pass HB40 flame retardant rating, and has poor chemical cracking resistance. This is because ABS-PCR belongs to a post-consumer recycled material, and the material ages, breaks macromolecular chains, and the physical properties and flame retardance are severely reduced.
From comparative example 2 and examples 1 and 2, the higher the ratio of the brand new ABS resin is, the better the mechanical properties of the recycled and regenerated ABS material are, but the flame retardant property and chemical resistance are still poor. This is because the brand new ABS has high mechanical properties and can improve the physical properties of the recycled ABS material. But its flame and chemical resistance cannot be altered.
Comparative examples 1, 2, 3, and 4 show that the addition of the halogen-free flame retardant can make the material satisfy HB grade, but the mechanical properties are reduced and the chemical resistance is worse. Since the halogen-free flame retardant belongs to small molecules, various physical properties of the material are reduced, and chemical resistance is reduced due to the existence of small molecules.
Comparative examples 3, 4, 5, and 6 show that the AS resin and the chemical-resistant toughening agent are adopted to replace part of completely new ABS resin, so that not only can each physical property of the material be improved, but also the chemical resistance of the material can be greatly improved. This is because the brand-new ABS resin contains unsaturated bonds and chemical resistance cannot be improved; the chemical-resistant toughening agent belongs to a fully saturated toughening agent, has good chemical resistance and can realize toughening.
Based on carbon emissions, the ABS-PCR amount was the highest in example 6 and carbon emissions was the smallest. And the flame retardant property and the chemical resistance are excellent, and the flame retardant ABS can be directly used for replacing brand new ABS to be applied to the air conditioner bottom shell.
