Description
1.one.
Изобретение относитс к строительным материалам, преимзгщественно к сырьевым смес м дл изготовлени теплоизол ционных материалов.The invention relates to building materials, mainly raw materials for the manufacture of thermal insulation materials.
Целью изобретени вл етс снижение водопоглощени и повышение прочности при сжатии, .The aim of the invention is to reduce water absorption and increase compressive strength,.
Теплоизол ционный материал на основе предлагаемой сырьевой смеси изготавливают путем смешени карбамидо- формальдегидной смолы с мелом и суль- фанолом с введением водного раствора ВАГа. непосредственно перед заливкой пеномассы в форму на движущуюс бумажную лент.у или в конструкцию. Перемешивание необходимо лишь дл равномерного распределени кстпонеитов. во всем объеме, поскольку смесь вл етс самовспенивакндейс , что способствует образованию структуры с преимущественно закрытыми порами и снижению водопоглощени .Thermal insulation material based on the proposed raw material mixture is made by mixing urea-formaldehyde resin with chalk and sul-fanom with the introduction of an aqueous solution of VAGa. immediately before pouring the foam into the mold on the moving paper tape or into the design. Stirring is necessary only to evenly distribute the chstpononeites. in its entirety, since the mixture is self-depressurized, which contributes to the formation of a structure with predominantly closed pores and a decrease in water absorption.
Примеры составов предлагаемой сырьевой смеси дл получени тепло- Цзол ционных изделий приведены в табл. 1.Examples of the composition of the proposed raw material mixture for the production of heat- generating products are given in Table. one.
Сравнительные физико-механические характеристики теплоизол ционного, материала, полученного на основе предлагаемой сырьевой смеси, приведены в табл 2.Comparative physicomechanical characteristics of the heat insulating material obtained on the basis of the proposed raw mix are given in Table 2.
Как видно из табл. 2, у теплоизол ционных изделий, полученных из предлагаемой сырьевой смеси, возрастает предел прочности при сжатии.As can be seen from the table. 2, for insulating products obtained from the proposed raw mix, the compressive strength increases.
существенно уменьшаютс влаго- и во- допоглощение, снижаетс технологическа усадка, сохран етс примерно в тех же пределах коэффициент теплопроводности и при этом материал ста- носитс трудносгораемым.moisture and water absorption are significantly reduced, technological shrinkage is reduced, the coefficient of thermal conductivity remains approximately within the same limits, and the material stays difficult to burn.
