Vozniuk G. Adhesive mixtures with high thermo-mechanical properties on the basis of alkaline aluminosilicate binder

The object of research - directed regulation of structure of alkali aluminosilicate binder in the system Na2O-K2O-Al2O3-SiO2-H2O to produce materials with properties that are necessary for heat-resistant adhesive mixtures. The object of research - a mixture of glue on the basis of alkali aluminosilicate binder in the system Na2O-K2O-Al2O3-SiO2-H2O. Purpose - development of heat-resistant adhesive mixtures with desired properties based on alkali aluminosilicate binder in the system Me2O-Al2O3-SiO2-H2O. Research methods - modern methods of physicochemical analysis, statistical methods for design of experiments. The novelty - established the possibility of connecting the system Na2O-K2O-Al2O3-SiO2-H2O with the properties required for the heat-resistant adhesive mixtures, by controlling the ratio of oxides in the binder in the direction of synthesis of analcime and zeolite ZK-14 with varying degree of order structure capable of to smooth dehydration and subsequent recrystallization in anhydrous compounds such as nepheline and leucite determining the thermal stability of artificial stone in conditions of high temperatures (up to 900 °C); designed and optimized adhesive compositions based on mixtures of alkali aluminosilicate binder, characterized by a viscosity viscometer Suttarda 150-180 mm, the viability of 45-90 min.; time fixing bonded materials for 1-2 hours., linear thermal expansion coefficient (8,43-8,65)o10-6 C-1, the compressive strength 52-68 MPa, the adhesive strength of 0, 92-1,6 MPa, the residual strength of 87% shrinkage of 1.72 % after burning at 900 °C and thermal stability 30 thermal cycles.
