Abstract

Сущность изобретени : сырьева  смесь дл  получени  теплоизол ционных изделий содержит следующие компоненты, мас.ч.: карбамидоформальдегидна  смола 100- 110; гидрофобный мел 7-15; сульфонол 0,5- 2,0; отвердитель - водный раствор ВАГ-3 - продукт конденсации сульфофенолмочеви- ны и формальдегида в смеси с ортофосфор- ной кислотой 30-50. Характеристики теплоизол ционных изделий: объемна  масса 80-100 кг/м3, предел прочности при сжатии 0,6-1,3 МПа, водопоглощение при погружении в воду за 24 ч 12-15% по объему , количество закрытых пор 60-65%, индукционный период 45-60 с. 2 табл.SUMMARY OF THE INVENTION: a raw material mixture for the production of thermal insulating products contains the following components, parts by weight: urea-formaldehyde resin 100-110; hydrophobic chalk 7-15; sulfonol 0.5-2.0; hardener VAG-3 aqueous solution is a condensation product of sulfophenol urea and formaldehyde mixed with phosphoric acid 30-50. Characteristics of thermal insulation products: bulk density 80-100 kg / m3, compressive strength 0.6-1.3 MPa, water absorption when immersed in water for 24 hours, 12-15% by volume, number of closed pores 60-65%, induction period 45-60 s. 2 tab.

Description

Изобретение относитс  к строительным материалам, преимущественно к сырьевым смес м дл  изготовлени  теплоизол ционных материалов.The invention relates to building materials, mainly raw materials for the manufacture of insulating materials.

Целью изобретени   вл етс  снижение водопоглощени  и удлинение индукционного периода.The aim of the invention is to reduce water absorption and lengthen the induction period.

.Это достигаетс  тем, что сырьева  смесь ,дл  получени  теплоизол ционных изделий содержит, мас.ч.: карбамидоформальдегидна  смола 100-110; отвердитель водный раствор ВАГ-3 - продукт конденсации сульфофенолмочевины и формальдегида в смеси с ортофосфорной кислотой 30-50; гидрофобный мел 7-15,сульфанол 0,5-3,0.. This is achieved in that the raw material mixture for the production of heat insulating products contains, by weight, urea-formaldehyde resin 100-110; hardener VAG-3 aqueous solution - a condensation product of sulfophenolurea and formaldehyde in a mixture with phosphoric acid 30-50; hydrophobic chalk 7-15, sulfanol 0.5-3.0.

Теплоизол ционный материал изготавливают путем смешени  компонентов непосредственно перед заливкой в форму .Thermal insulation material is made by mixing the components immediately before pouring into the mold.

Перемешивание необходимо лишь дл  равномерного распределени  компонентов во всем объеме, поскольку вспенивание осуществл етс  за счет химического взаимодействи  составл ющих, при этом увеличиваетс  содержание закрытых пор. Примеры составов предлагаемой сырьевой смеси приведены в табл.1.Mixing is necessary only for uniform distribution of the components throughout the volume, since foaming is carried out due to the chemical interaction of the components, while the content of closed pores increases. Examples of compositions of the proposed raw mix are given in table 1.

Свойства полученных теплоизол ционных изделий приведены в табл. 2.The properties of the obtained insulating products are given in table. 2.
