Description
Изобретение относитс к промышленности строительных материалов и может быть использовано при изготовлении теплоизол ционных и декоративно-акустических изделий дл гражданского и промьшшенного строительства, а также дл изол ции теплопроводов.The invention relates to the building materials industry and can be used in the manufacture of heat insulating and decorative acoustical products for civil and industrial construction, as well as for insulating heat pipes.
Целью изобретени вл етс повышение прочности при изгибе и структурной прочности.The aim of the invention is to increase the bending strength and structural strength.
Композицию дл изготовлени теплоизол ционного материала и издели из нее готов т следующим образом.A composition for the manufacture of a heat insulating material and an article thereof is prepared as follows.
Вспученный перлит тщательно перемешивают с жидким стеклом и оксидом кальци . Из полученной таким образом однородной массы формуют издели и дл введени в состав двуоксида углерода издели выдерживают в течение 1,5-2,0 ч в автоклаве, в среде двуоксида углерода при температуре до 300°С и давлении 0,11-0,50 Ша.Expanded perlite is thoroughly mixed with liquid glass and calcium oxide. From the homogeneous mass obtained in this way, the articles are molded and, for introduction into the composition of carbon dioxide, the products are kept for 1.5-2.0 hours in an autoclave, in an atmosphere of carbon dioxide at temperatures up to 300 ° C and pressure 0.11-0.50 Sha .
Составы композиции приведены в табл.1. При этом используют жидкое стекло по ГОСТ 13078-81, которое в композицию ввод т в водном растворе, плотность его составл ет 1,3-1,5 г/см, а модуль 2,5-3,0 г/см .The compositions of the composition are given in table.1. In this case, liquid glass according to GOST 13078-81 is used, which is introduced into the composition in an aqueous solution, its density is 1.3-1.5 g / cm, and the modulus is 2.5-3.0 g / cm.
