Vynález sa týká sposobu výroby povlako-vé] bezošvej strešnej krytiny, ktorá za úče-lom zvýšenia životnosti, účinnosti a dosiah-nutia podstatných ekonomických prínosov jezhotovená z definovaných spoluposobiacichnánosov, ktoré zabezpečujú hydroizolačně,dilatačně, pevnostně, mrazuvzdormé, hmot-nostně a estetické požiadavky v súčasne] do-bě požadované od krytin plochých striech.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for the production of a coating of a seamless roof covering which, by increasing the service life, efficiency, and substantial economic benefits, is defined by defined co-benefits which provide waterproofing, dilatation, strength, frost resistance, weight and aesthetic requirements. at the same time required from the covering of flat roofs.

Doposial sa střešně krytiny vyrábali pou-žitím vopred zhotovených polymérnych fó-lií na báze polyvinylchloridu, polyetylénu,chlórsulfokopolyetylénu s dalšími vrstvami,napr. pojenou štrkovitou, azbestolepenko-vou, vodonepriepustnou azbestocementovoua pod., niekedy tiež pomocou polymérnychfólií, asfaltových povlakov a rohoží v kom-binácii s kovovou fóliou. Známe je tiež po-užitie azbestovej plsti a melanínovej živice,sklenenej vaty impregnovanej tavitelnýmpolymérom, ďalej vrstiev vytvořených slinu-tím častíc róznych termoplastov. Rozšířenéje použitie zvuko a teploizolačných vrstievz penoplastov, napr. polyuretánu a polysty-rénu, najmá v kombinácii s bituménovýmpapierom.To date, roofing has been produced by using preformed polyvinylchloride, polyethylene, chlorosulfocopolyethylene based polymer films with additional layers, e.g. bonded pebble, asbestos-stick, water-impermeable asbestos-cement, and sometimes also with polymeric foils, asphalt coatings and mats in combination with a metal foil. Also known is the use of asbestos felt and melanin resin, a glass wool impregnated with a meltable polymer, further layers formed by saliva of rhodium thermoplastic particles. The use of sound and heat-insulating layers in penoplastics, such as polyurethane and polystyrene, has been enhanced, particularly in combination with bitumen paper.

Střešně krytiny, ktoré neobsahujú, popr.obsahujú výstužné vložky, sa obyčajne vy-tvárajú nanášaním ionogenných alebo neio-nogenných asfaltových emulzií samostatnéalebo sú kombinované zmesou kationaktív-nej živičnej emulzie a kaučukovej emulzie.Pozornosti si zaslúži použitie izolačnej vrst-vy obsahujúcej textilnú vložku impregnová-nu emulziou akrylátu, popr. oprava střechyza pomoci emulgačného prostriedku a vlá-kennej podložky.Roof coverings which do not contain reinforcing inserts are usually formed by deposition of ionic or non-ionic asphalt emulsions separately or combined with a mixture of cationic resin emulsion and rubber emulsion. Attention is drawn to the use of an insulating layer comprising an impregnated textile liner. with an acrylate emulsion or repairing the roof with an emulsifier and a sponge mat.

Uvedený stav techniky v krytinách nesiepopři nesporných výhodách celý rad nevý-hod, ktoré v ďalšom sposobujú známe pro-blémy plochých striech. Nalepené polymér-ne fólie, alebo na podklad natavované bi-tuménové pásy vplyvom nekvalitného mate-riálu, práce a starnutia často povolujú vspojoch, čo sa prejaví v neplnění hydroizo-lačnej funkcie. Takto převedené krytiny prinižších teplotách tvrdnú a pri priehybochstrešných konštrukcií nad podporou vply-vem záporných momentov praskajú. Vply-vom slnečného tepla sa stávajú plastickénatolko, že i nepatrné mechanické namá-hanie má rovnako za následok poškodenie.Váčšina bituménových krytin je nenasiaka-vá a teda i mrazuvzdorná, ale ktorákofvekzo spomínaných netěsností sposobí, že pokaždom zamrznutí sa trhlina zváčší a v ko-nečnej fáze zapříčiní zatekanie. Medzi ďal-šie nevýhody je možné zaradif vysoké hmot-nosti a ceny krytin vzhladom k ich životnos-ti, v iných prípadoch obsah zdraviu škodli-vých zložiek, hořlavost a prácnosť pri rea-lizácii.The prior art in roofing does not dispute a number of disadvantages, which are known in the art, which are known in the following by known flat roof problems. Adhesive polymer films, or bi-tumor bands that are melted on the substrate, due to poor material, labor and aging often permit bonding, resulting in non-performance of the waterproofing function. The cladding thus converted hardens at higher temperatures and bursts when the soffit structures over support the negative moments. The heat of the solar heat becomes plastic, so that even a slight mechanical load also results in damage. Most of the bituminous coverings are non-absorbent and thus frost-resistant, but any leakage will cause the crack to become wider and freeze. phase. Other drawbacks include the high weight and cost of roofing due to their lifetime, in other cases the health content of the harmful components, the flammability and the labor of realization.

Uvedené a ďalšie nevýhody rieši tento vy-nález, podlá ktorého sposob výroby povla-kovej strešnej krytiny s výstužnou textilnouvložkou, ktorá sa vytvára nanášaním viace-rých funkčných vrstiev hmot na báze synte- tických živíc natieraním a/alebo striekanímsa robí tak, že najskor sa postupné nanášana povrch nosnej strešnej konštrukcie vod-ná disperzia na báze polyvinylacetátu, vinyl-chloridu, vinylacetátu alebo ich kopolymé-rov, s výhodou so stúpajúcim obsahom suši-ny, a po položení textilnej výstuže, zaliatíma hrůbku 2 až 7 mm a stuhnutí sa na vy-tvořenu vrstvu nanáša hmota na báze chlór-kaučukov v organickom rozpúšťadle do do-siahnutia celkovej hrůbky krytiny obyčajnenepresahujúcej 10 mm. Výhodou prevedenia podlá vynálezu je ne-náročné vytvoremie súvislej plochy, čím od-padá problém „spojov“, ktoré sú najzrani-telnejším miestom. Vytvořená konštrukciaje dostatočne pružná tak, že unesie tvarovézměny a vplyvom povetrnostných podmienoknemení svoje vlastnosti. Dvojvrstvá kon-štrukcia sa vyznačuje nízkou hmotnosťoucca 2,8 až 4,0 kg . nr 2 pri hrúbke cca 3 až7 mm. Dalšími výhodami popři dosiahnutízvýšenia účinnosti a životnosti je dosiahnu-tie podstatných ekonomických prínosov,vzhladom k technickej dostupnosti surovin,zdravotná nezávadnost a vyššia požiarnabezpečnost krytiny, ako aj možnost tónova-nia farebných odtieňov počnúc bielou vrst-vou.This and other disadvantages are solved by the present invention, according to which the method of producing a coated roofing material with a reinforcing textile component which is formed by applying more functional layers of synthetic resin-based materials by coating and / or spraying is such that progressively applying the surface of the roof structure to an aqueous dispersion based on polyvinyl acetate, vinyl chloride, vinyl acetate or copolymers thereof, preferably with increasing drying content, and after laying the textile reinforcement, pouring in and crumbling 2 to 7 mm and solidifying to the resulting layer is applied to the chloro-rubber-based mass in an organic solvent until a total thickness of 10 mm is achieved. An advantage of the embodiment of the invention is the uncomplicated formation of a continuous surface, thereby eliminating the problem of "joints" which are the most vulnerable. The structure is sufficiently resilient to withstand shape changes and to prevent its properties from being affected by weather conditions. The bilayer construction has a low weight of 2.8 to 4.0 kg. nr 2 at a thickness of about 3 to 7 mm. Further advantages in achieving efficacy and durability are the achievement of substantial economic benefits, due to the technical availability of raw materials, health safety and higher fire safety of the covering, as well as the possibility of tinting color shades starting with the white layer.

Zloženie a končentrácia vodných disper-zi! polyvinylacetátu, vinylchloridu, vinylace-tátu alebo ich kopolymérov sa volí podlápodkladu (porézny, hladký, šikmý, bezspá-dový a pod.). Obyčajne, disperzie s obsahom43 až 67 % sušiny k vytvoreniu 0,1 až 1,0milimetra nátěru, ktorý má funkciu penet-račnú a hydroizolačnú, sa riedia v pomere1 : 8 až 1 : 2. Potom sa nanáša neriedenádisperzia na hrůbku 3 až 7 mm, v ktorej jezaliatá výstužná tkaná alebo netkaná tex-tília na báze prírodných a/alebo syntetic-kých vláken. Pre zabezpečenie dobrej stabi-lity a odparivosti vody z disperzného systé-mu je výhodná přítomnost tenzidov. Zmak-čovací účinok — vnútorná plastifikácia sadosahuje kopolymerizáciou, najma s vinyla-cetátom. U homopolymérov je vhodný prída-vok zmakčovadiel, napr. dibutylftalátu, tri-krezylfosfátu, dibutylsebakátu, polyglykol-adipátu atď. Ďalej můžu byť vo vodnej dis-perzii přítomné koalescentné látky, ochran-né koloidy, zahustovadlá, plnidlá (v obochvrstvách), biocídne prostriedky a retardé-ry horenia. Do polyvinylacetátovej disperziebez straty na účinku je možné primiešať fe-nolformaldehydové, močovinoformaldehy-dové alebo silikonové živice. V případe hmoty na báze chlórkaučukov,popři možnej přítomnosti plnidiel a pigmen-tov, je důležité rozpúšťadlo, kterým sa pod-statné ovplyvňujú technologické i ekonomic-ké vlastnosti vytvorenej ochrannej vrstvy.Možné je spravidla použit rozličné zmesirozpúšťadiel, často aj také, ktoré samostat-né použité daný materiál nerozpúšťajú [rie-didlá). Z kombinácii je možné uviesť: tolu-Composition and Concentration of Water Dispersions! polyvinyl acetate, vinyl chloride, vinyl acetate or copolymers thereof are selected from the sub-base (porous, smooth, oblique, bonded, etc.). Usually, a dispersion having a content of 43 to 67% of dry matter to produce a 0.1 to 1.0 millimeter of a coating having a penetration and waterproofing function is diluted in a ratio of 1: 8 to 1: 2. , wherein the stony reinforcing woven or nonwoven textile is based on natural and / or synthetic fibers. In order to ensure good stability and evaporation of water from the dispersion system, the presence of surfactants is preferred. Softening effect - internal plasticization is copolymerized, especially with vinyl acetate. For homopolymers, the addition of wetting agents such as dibutyl phthalate, tri-cresyl phosphate, dibutyl sebacate, polyglycol adipate, etc. may be appropriate. flame retardants. Phenol-formaldehyde, urea-formaldehyde or silicone resins can be mixed into the polyvinyl acetate dispersion through the loss of action. In the case of a chlorocarbon-based material, possibly in the presence of fillers and pigments, a solvent which substantially affects the technological and economic properties of the formed protective layer is important. the material used does not dissolve the diluents. The combination may include:
