Description
Изобретение относитс к строительным материалам и может быть использовано дл получени высокопрочных водостойких материалов. Известно в жущее на основе оксид магни и хромовой кислоты fl . Наиболее близким по технической сущности и достигаемому эффекту к предлагаемому вл етс в жущее 2 , включающее,%: хромова кислота 88-9 оксид магни 2,5-11,5t металл из р да Л1, В, Мд 0,5-3,5. Недостатками известных в жущих вл ютс неводостойкость в жущего. Цель изобретени - получение вод стойкого в жущего. Поставленна цель достигаетс те что в жуцее, включающее хромовую ки лоту, оксид магни и металл, содержит в качестве металла вольфрам и дополнительно ортофосфорную кислоту при следующем соотношении компонентов , мае.%; Хромова кислота3 ,6-7,7 9,5-18,6 Оксид магни 0,2-0,3 Вольфрам Ортофосфорна 73,4-86,7 кислота Пример. В водный раствор хромовой кислоты 80%-ной концентрации, нагретой до , при перемешивании последовательно ввод т порошок металлического вольфрама и ортофосфорную кислоту, после чего в полученную смесь ввод т порошкообразный оксид магни . Из полученного теста пластичной консистенции формуют образцы , которые сначала выдерживают . в водной среде, после чего их испытывают на прочность при сжатии (таблица ) . Приведенные в таблице данные показывают , что предлагаемое в жущее на основе хромовой кислоты, оксида магни , вольфрама и ортофосфорной кислоты позвол ет получить достаточно прочный водостойкий материал.The invention relates to building materials and can be used to produce high strength, water resistant materials. It is known to be based on magnesium oxide and chromic acid fl. The closest to the technical essence and the achieved effect to the proposed is a solid 2, including,%: chromic acid 88-9 magnesium oxide 2.5-11.5 t metal from row L1, V, Md 0.5-3.5 . The disadvantages of the known users are the non-water resistance of the user. The purpose of the invention is to obtain water resistant to a binder. This goal is achieved by those in the zhuzee, including chromic acid, magnesium oxide and metal, containing tungsten as a metal and, in addition, orthophosphoric acid in the following ratio of components, in%; Chromic acid 3, 6-7.7 9.5-18.6 Magnesium oxide 0.2-0.3 Tungsten Orthophosphoric 73.4-86.7 acid Example. In an aqueous solution of chromic acid of 80% concentration heated to, with stirring, metal tungsten powder and phosphoric acid are successively introduced, after which powdered magnesium oxide is introduced into the resulting mixture. From the obtained test plastic consistency molded samples, which are first incubated. in the aquatic environment, after which they are tested for compressive strength (table). The data in the table show that the proposed binder based on chromic acid, magnesium oxide, tungsten and orthophosphoric acid provides a sufficiently durable waterproof material.
