Získat však poměrně jednoduchým spósobom stavebný materiál, ktorý by mal všetky požadované vlastnosti a splňal náročné požiadavky nielen ako materiál nosný, ale súčasne aj izolačný, najma tepelnoizolačný, sa javí v doterajšej praxi poměrně obtiažne. Problémom je predovšetkým vzájomné spojenie jednotlivých komponentov, ktoré zabezpečujú potrebnú pevnost materiálu kvóli jeho nosným vlastnostiam, s komponentami, dodávájúcimi tomuto materiálu vlastnosti izolačné. Nezanedbatelným hladiskom pri výrobě stavebných materiálov je hladisko ekonomické, ktoré núti volit také technologie, ktoré si nevyžadujú zložitejšie výrobně zariadenia, dajú sa aplikovat bez zvýšenej pracnosti a energetickej náročnosti a z lahko dostupných a cenovo výhodných používané technologie v súčasnosti nemóžu splnit, nějšie používané sú v súčasnosti v ktorých sa uplatňuje v róznych materiálov s róznymi organickými Najváčším problémom u týchto lahčiaceho materiálu, váčšinou polystyrénu, tak, aby sa jednak rovnoměrně rozmiestnil v ostatných stavebnej zmesi a zabezpečila sa tak tak, aby sa okolo polystyrénu, váčšinou drtě nevytvořili drobné trhliny a medzery, surovin, čo váčšinouVarious types of materials are used in the prior art, which are currently being used in the construction of thermal and acoustic insulation construction by various technologies, selected according to the properties of the components used as the basic building elements of the final product. However, it is quite difficult to obtain a building material which has all the required properties and meets the demanding requirements not only as a load-bearing material but also insulating, in particular heat-insulating, in a relatively simple manner. In particular, the problem is the interconnection of the individual components, which provide the necessary strength of the material with a quota of its bearing properties, with the components imparting insulating properties to the material. A significant aspect in the production of building materials is the economic aspect, which forces such technologies that do not require more complex production equipment, can be applied without increased labor and energy intensity and can not meet the currently available and cost-effective technologies, others are currently used. in which it is applied in different materials with different organic materials The greatest problem with these pouring materials, mostly polystyrene, so that it is evenly distributed in the other building mix, ensuring that small cracks and gaps do not form around the polystyrene, mostly crumb, raw materials, which mostly

Uvedené problémy pri výrobě lahčených stavebných materiálov sa doteraz riešili viacerými možnými spósobmi. Napr. polystyrén sa před zmiešaním s cementom róznym spósobom upravoval - používali sa najma prostriedky na jeho chemickú úpravu, napr. nadúvadlá, pričom polystyrén sa naexpandoval a pósobením vyšších teplot sa zmes vytvrdila. Objemová hmotnost takto vyrobeného materiálu je však nesúrodá, čo negativné ovplyvňuje jeho pevnost. Ďalšou nevýhodou takéhoto postupu je jeho vyššia pracnost a energetická náročnost. Ďalšie známe postupy využívali na spájanie jednotlivých zložiek rožne živičné spojivá v kombinácii s potřebnými tvrdidlami. Pri uplatnění týchto spósobov výroby sa nevýhody prejavovali najma vo vyšších nákladoch základných surovin vo množstvu /cement, polystyrén, ako aj náročnosti vzhladom na potřebné konečné Navýše vlastnosti výsledných materiálov nejšie spojenie požadovaných pevnostných prilnutia živičného spojiva k polystymedzery, do ktorých prenikala vlhkost vztahu k ich použitému vo vyššej energetickej vytvarovanie materiálu, nedosahovali najoptimála izolačných vlastností.Known and most common production methods for building materials, combinations of porous or inorganic binders. The technology is incorporation with other constituents of the components of uniform strength and further in the form of spheres or which allow the formation of molds and also greater absorption of the finished product. To date, these problems in the production of lightweight building materials have been addressed in several possible ways. E.g. polystyrene was treated differently before mixing with the cement - in particular, chemical treatment agents were used, e.g. blowing agents, wherein the polystyrene expanded and cured at higher temperatures. However, the bulk density of the material thus produced is inconsistent, which negatively affects its strength. Another disadvantage of such a procedure is its higher labor intensity and energy consumption. Other known methods have used a bituminous binder in combination with the necessary hardeners to join the individual components. The disadvantages of using these production methods were the higher costs of the basic raw materials in quantities / cement, polystyrene, as well as the difficulty with respect to the required final properties of the resulting materials. in the higher energetic shaping of the material, did not achieve the optimum insulating properties.

Podstata vynálezuSUMMARY OF THE INVENTION
Uvedené nevýhody odstraňuje riesenie podlá vynálezu, ktorého tom, že poměrně nenáročným spósobom rieši l - polystyrénu do betónovej bez použitia nákladnějších výrobných či přídavných resp. materiálov, v porovnaní s viacerými postupmi menej náročné a s poměrně nízkými nárokmi na pracpodstata spočívá v problém zapracovania lahčiaceho prvku zmesi a to zariadení, energeticky nosí. Tým, že predpenený polystyrénový granulát sa núteným rotačným a súčasne planetárnym pohybom dokladné premieša so zámesovou vodou s přidaným lepidlom na báze polyvinylacetátovej disperzie v pomere 100 : 0,001 - 0,1, ktoré má aj v malých dávkách dobré lepivé vlastnosti, získá sa zmes zmáčaného polystyrénového granulátu, na povrchu dokonale pokrytého rovnoměrným lepivým filmom. Takto připravený polystyrénový granulát nost sa za stálého miešania rovnoměrně pieskom s velkosťou zrn 0,1 - 2 mm.The above-mentioned disadvantages are overcome by the solution according to the invention, in which it solves in a relatively simple manner l-polystyrene in concrete without the use of more expensive production or additional resp. In comparison with a number of processes, it is less demanding and with relatively low demands on labor. By thoroughly mixing the pre-foamed polystyrene granulate with forced rotational and planetary motion with the mixing water with added polyvinyl acetate dispersion adhesive in a ratio of 100: 0.001 - 0.1, which has good tack properties even in small doses, a mixture of wetted polystyrene is obtained. granulate, on a surface perfectly covered with a uniform adhesive film. The polystyrene granulate thus prepared is uniformly mixed with sand having a grain size of 0.1 - 2 mm while stirring.

přidávaného piesku sa dá vyrobit materiál s rožnou požadovanou pevnosťou a izolačnými vlastnosťami. Do zmesi sa napokon za stálého miešania přidává cement v hmotnostnom pomere 8 : 1 k pěnovému granulátu za súčasného prilievania zvyšnej zámesovej vody a dokladným premiešaním, minimálně 10-minútovým, sa získá výsledná zmes s rovnoměrně rozloženými jednotlivými základnými zložkami, bez vytvárania pieskových hniezd, či vyplavenia polystyrénového granulátu. Uvedeným spósobom výroby možno získat lahčenú polystyrénbetónovú zmes s velmi dobrými tepelnoizolačnými i zvukovoizolačnými vlastnosťami, ktorá však nostné parametre, a je teda vhodná objektov, ale aj objemovú hmotnost pódach. Týmto spósobom výroby získaný má pevnost porovnatelná s inými druhmi stavebných napr. s tehlou alebo pórobetónom, nízku objemovú /hustotu/ zváčša menšiu ako objemová hmotnost tiež dobrú odolnost proti teplu a vlhkosti a je proti prenikaniu rádioaktívneho žiarenia.In addition to the added sand, it is possible to produce a material with the desired strength and insulation properties. Finally, the cement is added to the mixture while mixing 8: 1 by weight to the foam granulate while pouring in the remaining mixing water and thoroughly mixing, for at least 10 minutes, to obtain the resulting mixture with uniformly distributed individual constituents, without forming sand nests. washout of polystyrene granulate. By means of this production method, it is possible to obtain a bottled polystyrene concrete mixture with very good thermal and sound insulating properties, which, however, has parameters of parameters and is therefore suitable for objects but also for the bulk density of the stages. The strength obtained by this method of production is comparable to other types of building, e.g. with a brick or aerated concrete, a low bulk / density / bulk less than bulk density also has good heat and moisture resistance and is resistant to the ingress of radioactive radiation.
