PAPER-LIKE NANOCOMPOSITE MATERIAL BASED ON MINERAL FIBERS FOR AIR COOLING SYSTEMS OF EVAPORATIVE TYPE Russian patent published in 2017 - IPC D21H13/36 D21H13/40 B82Y30/00 

FIELD: textile, paper.

SUBSTANCE: invention relates to a paper-like nanocomposite material based on mineral fibers which may be used as capillary-porous elements of air cooling systems of evaporative type. Mineral fibers are glass and/or basalt fibers with an average diameter of 0.4 microns. Binder is a sodium aluminate NaAlO₂ and aluminium sulphate Al₂(SO₄)₃ with the following ratio of components, wt %: mineral fiber - 50-90, NaAlO₂ - 5-25 (on Al₂O₃), Al₂(SO₄)₃ - 5-25 (on Al₂O₃). The material is produced with the traditional paperproduction equipment using a reflux method. The paper-like nanocomposite material is provided having strong characteristics of height and speed of water rise, water capacity and strength.

EFFECT: material is also characterised with thermal, chemo-, biostability, lack of toxicity and exhalation of substances in the air with harmful influence on the human body, resistant properties against mould, fungi and microorganisms in aqueous medium.
