Description

Изобретение относится к промышленности строительных материалов.The invention relates to the construction materials industry.

Известна сырьевая смесь, содержащая мас.%: минеральный заполнитель (вспученный перлит) 40,0-60,0; щелочной компонент (едкая щелочь) 3,0-5.0; некормовая солома 17,0-25.0; лузга зерновых культур 20,0-30,0 [1].Known raw material mixture containing wt.%: Mineral aggregate (expanded perlite) 40,0-60,0; alkaline component (caustic alkali) 3.0-5.0; non-feed straw 17.0-25.0; husk of grain crops 20.0-30.0 [1].

Задачей изобретения является повышение прочности теплоизоляционного материала.The objective of the invention is to increase the strength of the insulating material.

Технический результат достигается тем, что сырьевая смесь для изготовления теплоизоляционного материала, содержащая вспученный перлит, щелочной компонент и лузгу зерновых культур, в качестве щелочного компонента она содержит известь и дополнительно латекс дивинилстирольный, при следующем соотношении компонентов, мас.%: вспученный перлит 70,0-77,0; известь 3,0-5,0; лузга зерновых культур 18,0-24,0 латекс дивинилстирольный 1,0-2,0.The technical result is achieved in that the raw material mixture for the manufacture of heat-insulating material containing expanded perlite, an alkaline component and husk of cereals, as an alkaline component it contains lime and additionally divinyl styrene latex, in the following ratio of components, wt.%: Expanded perlite 70.0 -77.0; lime 3.0-5.0; husk of grain crops 18.0-24.0 latex divinyl styrene 1.0-2.0.

В таблице приведены составы сырьевой смеси и прочность теплоизоляционного материала.The table shows the composition of the raw mix and the strength of the insulating material.

Компоненты дозируют в требуемых количествах. Вспученный перлит измельчают до получения частиц фракции 2-3 мм. Измельченный перлит смешивают с лузгой зерновых культур и известью, добавляют воду и выдерживают до полного гашения извести, затем добавляют латекс дивинилстирольный и все еще раз перемешивают. Из полученной сырьевой смеси формуют панели или плиты, которые подвергают автоклавной обработке в атмосфере насыщенного пара при давлении 0,9 МПа и температуре 175°С в течение 8-10 часов.The components are dosed in the required amounts. Expanded perlite is crushed to obtain particles of a fraction of 2-3 mm. The crushed perlite is mixed with husk of grain crops and lime, water is added and kept until the lime is completely extinguished, then divinyl styrene latex is added and mixed again. From the obtained raw material mixture, panels or slabs are formed, which are autoclaved in a saturated steam atmosphere at a pressure of 0.9 MPa and a temperature of 175 ° C for 8-10 hours.

Теплоизоляционный материал, полученный из предложенной сырьевой смеси, отличается невысокой стоимостью, экологически безопасен.Thermal insulation material obtained from the proposed raw material mixture is not expensive, environmentally friendly.
