COATED PLANE POLYMERIC MATERIAL WITH A LIMITED TENDENCY TO FILLING WITH ALGAE, METHOD OF ITS FLOW PRODUCTION AND ITS APPLICATION

摘要

1. A flat polymer material with a limited tendency to algae fouling, containing: a) a thermoplastic polymer substrate as a base; and b) a photocatalytically active coating based on it, comprising: - a water distribution layer, which is a layer b1 + 2) of a sol and adhesion promoter containing a promoter adhesion and colloidal sol, or layer b2) of colloidal sol, ordered on layer b1) of the adhesion promoter deposited on the base a), and - ordered on the water-distributing layer b1 + 2) or b2) photocatalytically active layer b3), which can be obtained by applying and drying a mixture containing, in terms of the solids content in it, b31) from 1 to 25% of the mass. titanium dioxide and b32) from 75 to 99% of the mass. silicon dioxide and / or water-insoluble metal oxide or anionically modified silicon dioxide or metal oxide; moreover, titanium dioxide has a particle shape with an average primary particle size of less than 10 nm. 2. The flat polymer material according to claim 1, characterized in that the adhesion promoter layer b1) can be obtained by applying and drying an insoluble and mainly non-swellable in water, soluble in organic solvents organic polymer material with polar groups; and a water-distributing layer b2) can be obtained by applying and drying an inorganic colloidal sol; or a layer b1 + 2) of a sol and adhesion promoter can be obtained by combining an inorganic colloidal sol with an adhesion promoter, preferably an aqueous dispersion iey radiation curable polyurethane acrylate, coating a substrate with a) and drying and / or otverzhdeniya.3. Flat polymer material according to claim 1, characterized in that
