Hydrophobized limestone as filler in polymer materials
Апстракт
The article shows changes in certain mechanical properties of polyvinyl
chloride (PVC) depending on the quality of added limestone as a filler. Natural
limestone and limestone hydrophobicized with stearic acid were added.
Modification experiments were carried out with “wet” and “dry” processes in order
to find out the required amount of stearic acid for a complete surface coating of
limestone - degree of coating 99.90%. Coating of the limestone surface was
achieved in the “wet” process with 1.5% stearic acid, while in the “dry” process
the same degree of coating was achieved with 3% stearic acid. A significant
amount of both “wet” and “dry” modified limestone was prepared. Such a product
was added to PVC mixture in order to investigate mechanical properties of the
obtained PVC product. Research into the mechanical properties of PVC has shown
that PVC containing limestone modified by the “wet” process exhibits better
mechanical properties than that containing limestone modif...ied by the “dry”
process. For example, PVC obtained from a mixture containing limestone modified
by the “wet” process with 1.5% stearic acid shows a better tensile strength of 54.20
MPa, while limestone modified by the “dry” process with 3% stearic acid shows a
tensile strength 53.20 MPa.
