title: [FTIR research on the modification of plant oil pitch binders by polyester waste].
abstract: Various plant oil pitchs (cottonseed pitch, bean oil pitch, and mixed plant oil pitch) were used to prepare the plant oil pitch binders for casting. They were treated by polyester waste and processed by several technics such as esterifying. In the mean time, FTIR and TG were adopted to learn the structure, property, and sclerous mechanism of the binders. From the comparison with synthetic fat binder, the authors can see that the treated binders have similar components. They also have many excellent properties such as higher dry tensile strength and slower deflation velocity, which equal to or even exceed the properties of synthetic fat binder. Therefore, the treated binders, which were cheaper, can be used to make class I mold and core binders.
