Abstract

Способ изготовления пенополистирольной плиты, включающий смешение полистирола с нуклеатором - тальком, плавление смеси в экструдере, введение в расплав порообразователя и экструзию через плоскощелевую фильеру с последующим формованием плиты, отличающийся тем, что в качестве нуклеатора используют 10-12 мас.% смеси гранулированного талька (1,5-2,0 мас.%) с неорганическими добавками, остальное - полистирол, при этом в качестве неорганических добавок используют гранулированные диоксид кремния (2-3 мас.%), оксид титана (1-2 мас.%), гидроксид магния (1-4 мас.%), каолин (1-2 мас.%), кизельгур (до 1 мас.%). A method of manufacturing a polystyrene foam plate, including mixing polystyrene with a talc nucleator, melting the mixture in an extruder, introducing a blowing agent into the melt and extruding it through a flat slot die, followed by molding the plate, characterized in that 10-12 wt.% Granular talc mixture is used as a nucleator ( 1.5-2.0 wt.%) With inorganic additives, the rest is polystyrene, while granular silicon dioxide (2-3 wt.%), Titanium oxide (1-2 wt.%), Hydroxide are used as inorganic additives magnesium (1-4 ma s.%), kaolin (1-2 wt.%), kieselguhr (up to 1 wt.%).
