Изобретение относитс к строительным материалам и может быть использовано дл полздгени декоративно-отделочных теплоизол ционных материалов дл внутренней отделки и облицовки стен и потолков.The invention relates to building materials and can be used for half-building decorative and finishing thermal insulation materials for interior decoration and wall and ceiling cladding.
Цель изобретени - повышение прочности при сжатии, а также снижение :температуры термообработки.The purpose of the invention is to increase the compressive strength, as well as lowering: the heat treatment temperature.
Дл приготовлени композиции используют поливинилбутираль (используютс отходы производства поливинил- бутирал ), этилацетат технический, вспученный перлит фракции 0-5 мм с насыпной плотностью 70-80 кг/м, тет- раборат натри , пеностеклогранул т с размером зерен 2,5-40 мм и насыпной плотностью 55-75 кг/м. Пеностеклогранул т получают на основе вулканических стекол, раствора гидроксида натри и газообразовател путем смете- . ни ,гранул ции и вспучивани сьфцевых гранул,Polyvinyl butyral is used to prepare the composition (polyvinylbutyral production waste is used), technical ethyl acetate, expanded perlite fractions of 0-5 mm with a bulk density of 70-80 kg / m, sodium tetraborate, foamed glass granulate with a grain size of 2.5-40 mm and bulk density of 55-75 kg / m. Foam glass granules are obtained on the basis of volcanic glasses, a solution of sodium hydroxide and a blowing agent by means of a sweetener. neither, granulation and swelling of facial granules,
Технологи изготовлени теплоизол ционного материала следующа .The technology for making the thermal insulation material is as follows.
Приготавливают раствор поливинил- бутирал в этилацетате, туда ввод т тетраборат натри , вспученный перлит и пеностеклогранул т, перемешивают до гомогенизации, формуют и сушат при .80-100°С в течение 50-60 мин.A solution of polyvinylbutyral in ethyl acetate is prepared, sodium tetraborate, expanded perlite and foamglass pellets are added, stirred until homogenized, molded and dried at .80-100 ° C for 50-60 minutes.
При сушке улавливают пары этил- ацетата и после их концентрации возвращают обратно в технологический цикл.When drying, ethyl acetate vapors are captured and, after their concentration, are returned back to the production cycle.
В табл.1 пре,чставлены составы композиции дл изготовлени теплоизол ционного материала.In Table 1, the compositions of the composition for the manufacture of the heat insulating material are given.
