A study of organic treatments on titanium dioxide pigment for rigid poly(vinyl chloride)
thesis
posted on 2018-07-31, 10:28 authored by Boon-Cheng LimThe objective of this project was to investigate different types of organic compounds applied onto rutile titanium dioxide (TiO2) and to determine how
each of them affects the processing and properties of rigid poly(vinyl chloride)
(PVC).
The first part of the research was an initial study on three types of organic-coated
pigments. Sample 1 consisted of 0.2 weight % trimethylol propane
(TMP) and 0.5 weight % poly(dimethyl siloxane) (PDMS), whereas samples 2
and 3 were single coated with 0.3 weight % TMP and O.B weight % n-octyl-phosphonic
acid (OPA), respectively. The dispersion behaviour of coated
pigments in liquid paraffin and water indicated that sample 1 was hydrophobic,
sample 2 was hydrophilic and sample 3 was amphipathic. [Continues.]
