Claims (3)

1. Способ получения самозатухающих вспененных плит, включающий смешение полистирола с антипиреном гексабромциклододеканом и синергетической добавкой, а также с нуклезатором, плавление смеси в экструдере, введение в расплав порообразователя и экструзию через плоскощелевую фильеру с формованием пеноплит, отличающийся тем, что в качестве синергетической добавки вводят смесь три-(2,4-дитретбутил)фосфита с октадецил-3(3,5-дитретбутил-4-гидроксифенил)пропионатом, взятых в соотношении 4: 1, в количестве 0,005-0,1 мас. % экструдируемой смеси.1. A method of producing self-extinguishing foam plates, comprising mixing polystyrene with flame retardant hexabromocyclododecane and a synergistic additive, as well as with a nucleizer, melting the mixture in an extruder, introducing a blowing agent into the melt and extruding through a flat slot die with molding foam foam, characterized in that it introduces synergistic a mixture of tri- (2,4-ditretbutyl) phosphite with octadecyl-3 (3,5-ditretbutyl-4-hydroxyphenyl) propionate, taken in a ratio of 4: 1, in an amount of 0.005-0.1 wt. % extrudable mixture. 2. Способ по п. 1, отличающийся тем, что в качестве полистирола используют полистирол с показателем текучести расплава 2,0-3,5 г/10 мин. 2. The method according to p. 1, characterized in that polystyrene is used as a polystyrene with a melt flow rate of 2.0-3.5 g / 10 min. 3. Способ по п. 1, отличающийся тем, что в качестве нуклезатора используют тальк с дисперсностью частиц 3-10 мкм в количестве 0,2-1,5 мас. % смеси и гидроксид алюминия в количестве 0,01-0,06 мас. % смеси. 3. The method according to p. 1, characterized in that as a nucleator use talc with a particle size of 3-10 microns in an amount of 0.2-1.5 wt. % of the mixture and aluminum hydroxide in an amount of 0.01-0.06 wt. % of the mixture.
