Abstract
Изобретение относитс к огнеупорной промышленности, а именно к периклазоуглеродистым огнеупорам, используемым в черной металлургии дл футеровки различных высокотемпературных тепловых агрегатов. Дл повышени смачиваемости компонентов углеродсодержащей шихты, повышени предела прочности при сжатии свежесформованного материала дополнительно ввод т диэтиленгликоль, а в качестве структурирующего агента-полиэтиленполиамин при следующем соотношении компонентов, мас.%: фурфуролацетоновый мономер (ФАМ) 58,0-60,2The invention relates to the refractory industry, namely to periclase-carbon refractories used in the steel industry for lining various high-temperature thermal units. To increase the wettability of the components of the carbon-containing charge, increase the compressive strength of the newly formed material, diethylene glycol is additionally introduced, and polyethylenepolyamine is used as a structuring agent in the following ratio of components, wt.%: Furfurolacetone monomer (FAM) 58.0-60.2

Description
Изобретение относитс к получению полимерньк св зующих дл огнеупорных материалов и может быть использовано Б производстве безобжиговых углерод- содержащих огнеупоров.The invention relates to the production of polymeric binders for refractory materials and can be used in the manufacture of unburned carbon-containing refractories.
Целью изобретени вл етс повышение смачиваемости св зующим шихты и увеличение прочности при сжатии свежесформованного материала.The aim of the invention is to increase the wettability of the binder mixture and increase the compressive strength of the newly formed material.
Приготовление предлагаемого св зующего дл углеродсодержащих огнеупоров осуществл ют в следующей последовательности . Фурфурол-ацетоновый мономер (ФАМ) в течение 1-2 мин смешивают с диэтиленгликолем. Затем при посто нном перемешивании добавл ют каменноугольную смолу (до получени однородного продукта). Перед приготовлением огнеупорного материала к полученному продукту добавл ют поли- этиленполиамин, перемешивают в течение 3-5 мин,The preparation of the proposed binder for carbon-containing refractories is carried out in the following sequence. Furfural-acetone monomer (FAM) is mixed with diethylene glycol for 1-2 minutes. Then, with constant mixing, coal tar is added (until a homogeneous product is obtained). Before preparing the refractory material, polyethylenepolyamine is added to the obtained product, stirred for 3-5 minutes,
Составы полимерного св зующего приведены в табл. 1, свойства - в табл, 2.The compositions of the polymeric binder are given in table. 1, properties - in the table, 2.
Применение предлагаемого св зующего позвол ет по сравнению с известными повысить смачиваемость св зующим углеродсодержащей шихты, краевой угол смачивани снижаетс на 5,4- 6,2%, повысить предел прочности при сжатии свежесформоваиного материала в 2,6-4,6 раза.The use of the proposed binder allows, in comparison with the known ones, to increase the wettability of the binder of the carbon-containing mixture, the wetting angle decreases by 5.4-6.2%, to increase the compressive strength of the newly formed material by 2.6-4.6 times.
Использование предлагаемого св зующего не требует применени специального дорогосто щего оборудовани , способствует снижению выхода бракованных изделий.The use of the proposed binder does not require the use of special expensive equipment, it contributes to reducing the yield of defective products.
