Abstract
Conform inventiei, procedeul pentru obtinerea compoundului expandabil pe baza de polistiren, destinat imitatiei de lemn, consta în aceea ca efectueaza amestecarea la cald apolistirenului granulat cu un agent de umectare macromolecular solid la temperatura camerei cu interval de topire 30...80 degree C, ales dintre oligomeri de etilena, de stiren sau de esteri ai acizilor grasi la temperatura de 30...80 degree C, în raport în greutate de 92...93 parti polistiren la 3...4 parti agent de umectare, dupa care se introduce, la aceeasi temperatura, agentul de expandare de tip ureoformaldehida si coloranti si se continua amestecarea la rece, timp de 5...10 min.
