Description
Изобретение относитс - к строителбным материалам, в частности к маС.сам дл изготовлени - древесностру ечных плит теплоизол ционного и конструкционного назначени на основе древесных отходов и фосфатных св зующих.The invention relates to construction materials, in particular, masses for the manufacture of wood-based heat insulating and structural boards based on wood waste and phosphate binders.
Цель изобретени - снижение набуооани , водопоглощени , влажности и повышение огнестойкости.The purpose of the invention is to reduce water absorption, water absorption, moisture and increase fire resistance.
Масса дл изготовлени теплоизол ционных и конструкционных материалов содержит, мае..%: измельченные отходы древесины - основа, алюмофос- фатное .св зующее 24-40, закись меди 8-13; малонова кислота 3-5.The mass for the manufacture of thermal insulation and structural materials contains, in May ..%: ground wood waste - the basis, alumino phosphate binder 24–40, cuprous oxide 8–13; malonic acid 3-5.
V V
Алюмофосфатна св зка легко пропитывает отходы древесины и вступает во взаимодействие cCu20, причем закись меди образует нерастворимые фосфаты меди, повыша водостойкость, огнестойкость, бактериальную и грибковую стойкость, снижает набухание и водопоглощение композиции.The aluminophosphate bond readily impregnates wood waste and reacts with cCu20, with cuprous oxide forming insoluble copper phosphates, increasing water resistance, fire resistance, bacterial and fungal resistance, reduces swelling and water absorption of the composition.

Составы готовились следующим образом.The compositions were prepared as follows.
Предварительно готовилось алюмофосфатное св зующее. К 70 вес.ч.Alumophosphate binder was preliminarily prepared. To 70 weight.h.
10 ортофосфорной кислоты, нагретой до , прибавл лось при перемешивании 15 вес.ч. гидрата окиси алюмини и вода 30 вес.ч. Затем в алюмофосфатное св зующее добавл етс малонова 10 orthophosphoric acid, heated to, was added with stirring to 15 weight.h. hydrate of aluminum oxide and water 30 weight.h. Then malonic acid is added to the aluminophosphate binder.
15 кислота. Полученное св зующее перемешивали с опилками и закисью меди. Из полученной массы прессовали издели 1 ООх 1 ООх 12 и др. при- давлении 22-25 кг/см и 150°С путем двукрат20 него прессовани по 10 мин. Все15 acid. The resulting binder was mixed with sawdust and cuprous oxide. From the resulting mass, products of 1 OOx 1 OOx 12 and others were pressed at a pressure of 22–25 kg / cm and 150 ° C by double pressing for 10 minutes each. Everything
