Изобретение относитс  к способам получени  теплоизол ционных материалов на основе вснучивающихс  масс.The invention relates to methods for producing heat insulating materials based on vns of masses.

Известный способ изготовлени  пористых огнеупорных материалов путем нагрева вспучивающихс  масс. Однако издели , полученные но известному способу, непригодны дл  службы при высоких температурах.A known method of manufacturing porous refractory materials by heating the intumescent masses. However, products produced by a known method are unsuitable for service at high temperatures.

Цель изобретени  - обеспечить снижение температуры вспучивани .The purpose of the invention is to reduce the temperature of expansion.

Достигаетс  это тем, что в качестве исходной массы используют составы на основе металлофосфатных св зующих, а нагрев осуществл ют до 150-250°С.This is achieved by using metal phosphate binder based compositions as the initial mass, and heating is carried out up to 150-250 ° C.

Например, на основе смеси хромалюмофосфатного св зующего с отнощениемFor example, based on a mixture of a chromium-phosphate binder with a ratio
