Изобретение относитс к композици м , вспенивающимс при нагревании под действием газов, выдел ющихс при разложении газообразователей, и может найти применение в промьшшенности тепло- и звукоизол ционных мат ериалов , искусственной кожи, декоративных .отделочных покрытий и других материалов на основе пластифицированного пенополивинилклорида.The invention relates to compositions that foam when heated under the action of gases released during decomposition of gas formers, and can be used in the industrial heat and sound insulation materials, artificial leather, decorative coatings and other materials based on plasticized polyvinyl chloride.
Известна композици , включающа поливннилхлорид, пластификатор,стабилизатор , порофор, вспенивающа с при нагревании за счет разложени азодикарбонамида.A known composition comprising polyvinyl chloride, a plasticizer, a stabilizer, a porophore, which foams when heated due to the decomposition of azodicarbonamide.
Однако вспенивание такой композиции ТБЬрбует длительной выдержки при высокой температуре . (140-180°С) р.However, the foaming of such a composition requires prolonged exposure to high temperature. (140-180 ° C) p.
Наиболее близкой по технической сущности к предлагаемой вл етс композици дл получени пенопласта, включающа поливинилхлорид, диоктил фталат, азодикарбонамид и активаторThe closest to the technical essence of the present invention is a composition for the preparation of foam plastic, including polyvinyl chloride, dioctyl phthalate, azodicarbonamide and activator
его разложени . В качестве активатора разложени азодикарбонамида композици содержит смесь моч-евины и К - Zn - 2-зтилгексоата в виде раствора в триэтиленгликоле 2}. . Врем термообработки указанной композиции снижаетс до 15 мин, но все же остаетс достаточно длительным ,.лто ограничивает использование такой композиции в непрерывных процессах производства. Кроме того, необходимо использовать растворитель, это также существенно ограничивает область ее применени .its decomposition. As an activator of the decomposition of azodicarbonamide, the composition contains a mixture of urea and K-Zn-2-ethylhexoate as a solution in triethylene glycol 2}. . The heat treatment time for this composition is reduced to 15 minutes, but still remains quite long, and this limits the use of such a composition in continuous production processes. In addition, it is necessary to use a solvent, this also significantly limits its scope.

Цель изобретени - повышение термостабильности композиции и ускорение процесса ее вспенивани .The purpose of the invention is to increase the thermal stability of the composition and accelerate the process of its foaming.
