Inventions in the nanotechnological area provide improved performance characteristics of different sealing polymer materials used in construction

The invention ?The method to produce nanopowder of zinc oxide with the surface modification for the use in construction sealing materials (RU 2505379)? can be used as building mastic exposed to high deforming loads and requires increased reversible percent elongation. Modified powder of zinc oxide is produced by precipitating salt solution. Obtained powder is treated in diluted polymer solution in nonpolar dissolvent, after that it is thermally treated to polymerize obtained coating. This method increases tensile strength and the extent of deformationof building sealing materials. The invention ?The method to produce polymer composition (variants) (RU 2506283)? can be used in the manufacture of building materials and other industries. The invention allows saving time needed for technological proces running as well as labour intensivity of the products and their cost.
