The review of patents in the area of nanotechnologies and nanomaterials. Part 1

The inventions in the area of nanotechnologies and nanomaterials produce a profound effect in construction, housing and communal services and adjacent economic fields. The invention «The method of production of mixture for composite honeycomb concrete (RU 2543847)» refers to the field of construction materials and can be used to produce non-autoclave composite honeycomb concrete of the natural hardening. This method consists of the following stages: supply of composition elements into mixer, mixing of the elements to obtain homogenous mass, introduction of dry cellulating mixture into obtained composition and further joint mixing; then obtained composition is provided with zeolite additive which is produced by means of preliminary mixing of one- or multilayer nanotubes in water with atomizer in sprayed form with further mixing with zeolite in the cyclic action mixer, the preliminary prepared dry cellulating mixture is also added. The technical result is a production of homogenous dry mixture, decrease of volume weight, increase of strength and frost resistance of non-autoclave honeycomb concrete manufactured from the specified dry mixture. The invention «Nanostructured wood and mineral composite material (RU 2542025)» refers to the production of construction materials and can be used in manufacture of wood and mineral slabs and finishing materials in civil and industrial engineering. The technical result is increased strength and water-resistance. The specialists may be also interested in the following nanotechnological inventions: epoxy composition for high-strength, alcali-resistant structures (RU 2536141); nanocomposite material based on mineral binders (RU 2538410); the method to produce nanopowders of zinc oxide with surface modification for the use in building sealing material (RU 2505379); a composition for conglutination of metal products (RU 2526991); the method for production of nanodispersed powders (RU 2537678); the method of synthesis of micro- and nanocomposite aluminium and carbon materials (RU 2537623); the production method for films of amorphous silica containing nanocrystal inclusions (RU 2536775); the method of ultrasound finishing treatment for details made of structural and tool steel and a device to perform it (RU 2530678); nanostructured welding wire (RU 2538228)
