(54) OMIETKOVÁ ZMES PEE VNÚTORNÉ TENKOVRSTVÉ ÚPRAVY STAVEBNÝCH KONŠTRUKCll(54) PEE PLASTERING INTERNAL THIN-LAYER CONSTRUCTION OF BUILDING STRUCTURES
Vynález sa zaoberá zložením omietkovej zmeel pre vndtornú povrchová úpravu velkorozměrových prvkov z betonu, pórobetonu, dřevovláknitých doeák, azbestocementu apod.The present invention is concerned with the composition of render plaster for internal surface treatment of large-dimensional elements made of concrete, aerated concrete, fibreboard, asbestos-cement and the like.
Doterajšie stierkové hmoty vyrábané u nás i v zahraničí na apojivovej báze vodných disperzi! syntetických živíc (prevážne homológov pólyvinylácetátu), modifikačných přísad (vo vodě rozpustných derivátov celulózy) fungicídnych, resp. inhybičných přísad korózie a jemných plniv frakcie do 0,7 mm, určené pre vnútorné úpravy hladkých a rovných povrchov konštrukčných prvkov stavebných objektov, sa nemóžu efektívne uplatnit pri aplikácii na kavernovité a nerovné podklady, pretože ich třeba vopred vyspravil vápennocementovými, alebo polymércementovými maltami.Existing screed materials produced in the Czech Republic and abroad on the basis of binder dispersions of water! synthetic resins (predominantly polyvinyl acetate homologs), modifying additives (water-soluble cellulose derivatives), fungicidal, resp. Corrosion and fine fillers with a fraction of up to 0.7 mm, intended for interior treatment of smooth and even surfaces of structural elements of building objects, cannot be effectively applied when applied to cavernous and uneven substrates, because they have to be repaired beforehand with lime-cement or polymer cement.
Tieto nevýhody odstraňuje omietková zmes podlá vynálezu, ktorého podstata spočívá v tom, že obsahuje vodou nerozpustná minerálnu látku frakcie do 1,5 mm v množstve 60 až 75 hmotnostných %, 2 až 5 hmotnoatných % 50 %-ného vodného systému polymérov syntetických živíc, napr. homopolymérov, polyvinylacetátu, polymetylmetakrylátu, kopolymérov, vinylacetátbutylakrylát, vinylacetát - 2 etylhexilakrylát, vinylacetátstyrénakrylét apod. s prídavkom 0,1 až 1 % proti-pliesňových přísad, pokial si to vyžaduje aplikácia hmoty v priestoroch so zvýšenou relativnou vlhkoslou (plavárne, práčovne apod,), 0,2 až 0,8 hmotnoatných % vodou rozpustných derivátov celulózy, napr. metylcelulózy, karboximetylcelulózy apod., 1 až 3,5 hmotnostných %These disadvantages are overcome by the plaster composition according to the invention which comprises a water-insoluble mineral of fraction up to 1.5 mm in an amount of 60 to 75% by weight, 2 to 5% by weight of a 50% aqueous system of synthetic resin polymers, e.g. . homopolymers, polyvinyl acetate, polymethyl methacrylate, copolymers, vinyl acetate butyl acrylate, vinyl acetate - 2 ethylhexilacrylate, vinyl acetate styrene acrylate and the like. with an addition of 0.1 to 1% of antifungal additives, if required by application of the mass in areas with increased relative humidity (swimming pools, laundries, etc.), 0.2 to 0.8% by weight of water-soluble cellulose derivatives, e.g. methylcelluloses, carboximethylcelluloses and the like, 1 to 3.5% by weight
201 182 montmorillonitu a vodu v množstve 15 až 30 hmotnostných Za účelom zvýšenia tixotropného efektu omletkovej zmesi určenej pře nanášanie vo vrstvách nad 3 mm přidává aa 0,3 až 1 hmotnostných % vodného roztoku alkalických kremičitanov hustoty do 50° Bé.201 182 montmorillonite and water in an amount of 15 to 30% by weight In order to increase the thixotropic effect of the plaster mixture to be applied in layers above 3 mm, aa 0.3 to 1% by weight of an aqueous solution of alkaline silicates is added.
Omietková zmes pódia tohoto vynálezu sa nanáša slimákovými čerpadlami. Rozptýlená tlakovým vzduchom cez zmešovaciu piětolu vytvára na povrchu upraveného prvku vrstvu, ktorá sa po miernom zavadnutí, připadne iahkom zatiahnutí kovovým hladítkom začisíuje hladltkom z pěnového polystyrénu, korku apod. Vrstva v hrůbkách nad 3 mm sa po nastrlekaní može atierkovať. Okrem nastriekávania sa može nanášal kovovým hladítkom. Po zahuštění cementom sa dá vhodné použií pre vačšie výspravky konštrukčných prvkov (styky panelov, poškodené časti apod.).The plaster mixture according to the invention is applied by means of screw pumps. Dispersed by compressed air through the mixing gun, it forms a layer on the surface of the treated element which, after a slight setting or a slight retraction with a metal trowel, is cleaned with a foam polystyrene, cork or the like. Thicknesses over 3 mm can be perforated after spraying. In addition to spraying it can be applied with a metal trowel. After thickening with cement, it is suitable to use for larger repairs of structural elements (panel joints, damaged parts, etc.).
