Study of thermal state, water absorption and strength properties of composite polymerpolymer binders

In this article, in order to improve the heat-water resistance and strength properties, the modification of urea-formal- dehyde polymeric materials is considered by introducing melamine and acrylonitic resins and reactive compounds into their composition. Shown by identifying the optimal ratios of urea-formaldehyde, melamine and acrylonitrile resins and the corresponding reactive compounds in increasing the heat-water resistance and shear strength of adhesive joints based on them, replacing expensive phenol-formaldehyde resins used in gluing basalt fibrous masses in the production of build- ing heat-insulating sheet materials.
