Abstract:
Kaolin Dukhla have been used as a filler for polysterne polymer. After acid treatmentby
kaolin with (10N)HCl to remove soluble oxides and filtering by distilled water, followed by
00,300, 400)oC for two calcinations the separated materials each at different temperature (100,
hr. The clay was milled and treated with PVA solution, which was firstly prepared for this
purpose. After that the treated clay with PVA, dried, milled and particle size less than 50 µm
were selected. Polysterne solution was prepared. Untreated and treated clay with respect to the
process parameters were added to polystrene. Also adding in other steps surffucent, hardners,
antioxidenet to prepare another samples. These parameters were studied to show their effect on
mechanical and thermal properties of polysterene.
The result shows that the modified clay gives an mechanical and thermal properties more stable
as a function of calcination temperature and higher acceptance as compared with the standard
value that measured for polysterene alone.
