| titleOfInvention | FILTERING HEAT RESISTANT NANO-FIBER MATERIAL AND METHOD FOR PRODUCING IT |
| abstract | 1. Filtering heat-resistant nanofiber material containing an inner working layer and two outer protective layers placed on both sides of the working layer, the working layer containing polydiphenylenephthalide fibers with a diameter of 200-400 nm, made by electrospinning, and has a mass of unit area equal to 0, 5-3.5 g / m, and the protective layers are made of non-woven quartz material. 2. The material according to claim 1, characterized in that the protective layers have a mass unit area of 6-8 g / mi contain silica fibers with a diameter of 1-7 microns. The material according to claim 1, characterized in that the aerodynamic resistance of the material to air flow with a linear velocity of 1 cm / s is 20-40 Pa. A method of obtaining a filtering heat-resistant nanofiber material described in claim 1, which consists in the fact that the working layer nanofibers are electroformed in an electric field with a strength of 2-6 kV / cm from a solution of polydiphenylenephthalide in cyclohexanone, at a concentration of polydiphenylenephthalide of 11-14 wt.%, when the content of an electrolytic additive selected from tetraethylammonium and tetrabutylammonium halides in an amount of 0.1-0.2 wt.%, with a solution viscosity of 0.3-0.9 Pa · s and the conductivity of the solution 50-100 μS / s , The formed nanofibres deposited on a substrate of protective nonwoven quartz material, whereupon the working layer is molded on the substrate is applied a second protective layer made of the same nonwoven materiala.5. The method according to claim 4, characterized in that the electroforming of the nanofiber working layer is carried out using a device equipped with a forming electrode made in the form of a comb, with |
