Изобретение относитс к производству строительных материалов, а именно к способам обработки пенополистирольного заполнител дл легкого бетона.The invention relates to the production of building materials, in particular to methods for treating a polystyrene foam aggregate for lightweight concrete.
Известен способ получени заполнител дл легкого бетона путем обработки предварительного вспененных гранул полистирола известковым молоком и последующей термообработки при 100-150°С в течение 10-20 мин 1.A known method for producing aggregates for lightweight concrete is by treating the pre-expanded polystyrene granules with lime milk and subsequent heat treatment at 100-150 ° C for 10-20 minutes 1.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ обработки пенополистирольного заполнител дл легкого бетона , включающий нанесение полимерного покрыти на гранулы пенополистирола и последующую сушку их 2.The closest to the invention to the technical essence and the achieved result is the method of processing polystyrene foam aggregate for lightweight concrete, including the application of a polymer coating on polystyrene granules and their subsequent drying 2.
Недостатки таких способов заключаютс в большом расходе полимерных материалов и в невысокой прочности получаемых гранул .The disadvantages of such methods are the high consumption of polymeric materials and the low strength of the obtained granules.
Цель изобретени - повышение прочности заполнител и уменьшение расхода полимера .The purpose of the invention is to increase the strength of the aggregate and reduce polymer consumption.
Достигаетс это тем, что по способу обработки пенополистирольного заполнител дл легкого бетона путем нанесени полимерного покрыти на гранулы пенополистирола и последующей сушки их, гранулы пенополистирола перед нанесением покрыти This is achieved by the fact that the method of processing polystyrene filler for lightweight concrete by applying a polymer coating on polystyrene foam granules and then drying them, foam polystyrene granules before coating
обрабатывают парами ацетона и подсушивают , а покрытие нанос т в аэрозольной среде полимера в течение 2-5 с.treated with acetone vapor and dried, and the coating is applied in an aerosol medium of the polymer for 2-5 seconds.
Нанос т покрытие в аэрозольной среде поливинилбутиральэпоксиднофенол - формальдегидного кле .The coating is applied in an aerosol medium to polyvinyl butyral epoxy oxidophenol - formaldehyde glue.
Н р и м е р. Обрабатывают вспученные полистирольные гранулы на опытной установке , состо щей из вертикальной трубы, разделенной на зоны, в которых создают требуемые технологические услови . Вначале гранулы пенополистирола размером 1,2- 5 мм из бункера нодают в зону, где подN p and meer. The expanded polystyrene granules are processed in a pilot plant consisting of a vertical pipe divided into zones in which the required process conditions are created. At first, expanded polystyrene granules with a size of 1.2-5 mm from the bunker are poured into the zone, where under
воздействием паров ацетона происходит оплавление и упрочнение поверхности гранул , затем их подвергают подсушиванию. Покрытие нанос т путем последовательного перемещени подсушенных гранул черезexposure to vapors of acetone is the melting and hardening of the surface of the granules, then they are subjected to drying. The coating is applied by sequentially moving the dried granules through
