Způsob výroby izolačního materiálu J3bl,as±—t.e.chhiky.A method for producing J3bl, as ± —t.e.chhiky insulating material.
Vynález se týká izolačního materiálu, zejména tepelněizolačního materiálu a materiálu pro izolaci kročejovýchhluků, a způsobu jeho výroby.BACKGROUND OF THE INVENTION The present invention relates to an insulating material, in particular to a heat insulating material and a sound insulation material, and to a method for producing the same.
Dosavadní stav techniky Běžné izolační materiály, např. z pěnového plastu jakoje pěnový polystyrén, mají tu nevýhodu, že nedýchají, to zna-mená, že nepropouštějí v dostatečné míře vzduch. To ovlivňujeklima v prostorech, izolovaných takovými materiály. Účelem vynálezu je proto vytvořit materiál, propouštějí-cí v uspokojivé míře vzduch, a vypracovat způsob jeho výroby.BACKGROUND OF THE INVENTION Conventional insulating materials such as foamed polystyrene foam have the disadvantage that they do not breathe, that is to say they do not impart sufficient air. This affects the warmth in spaces that are isolated with such materials. It is therefore an object of the present invention to provide a material which permits a satisfactory air flow and to provide a process for its production.
Podstata vynálezuSUMMARY OF THE INVENTION
Podstata způsobu podle vynálezu spočívá v tom, že serozvlákněný papír smíchá s vodou, vápnem a křemennou mouč-kou a poté se podrobí tepelnému zpracování při teplotě vyš-ší než 200 °C. Způsob podle vynálezu tedy umožňuje použitívláken papíru vyrobených ze starého papíru a zpracovanýchzpůsobem podle vynálezu v izolační materiál, který má malouhustotu a nízkou tepelnou vodivost. Mimoto má dostatečnoupevnost v tlaku, aby ho bylo možno použít k pokrytí podlahyza účelem tlumení kročejového hluku. Materiál podle vynále-zu je velice dobře použitelný jako podklad pod omítku,protože na jeho povrchu je vápno nebo kalcit. Přísadou hy—drofobizačního činidla lze dosáhnout toho, že izolační ma-teriál je odolný proti vlhkosti a tedy proti povětrnostnímvlivům.The essence of the process according to the invention consists in mixing sero-fiber paper with water, lime and quartz flour and then subjecting it to heat treatment at a temperature above 200 ° C. Accordingly, the method of the invention allows the use of paper fibers made from old paper and processed according to the invention into an insulating material having low density and low thermal conductivity. In addition, it has sufficient compressive strength to be used to cover the floor for impact sound absorption. The material according to the invention is very well usable as a plaster backing because lime or calcite is on its surface. The addition of a hydrophobising agent can result in the insulation material being resistant to moisture and thus to weather influences.
Iv, 2 Příklad provedení vynálezuIV, 2 An embodiment of the invention
Ze starého papíru byla vyrobena běžným způsobem papíro-vá vlna, která sestávala z lehce zplstěných papírových vlá-ken. 1,4 kg těchto papírových vláken bylo namočeno do 4,5 1vody, přičemž do vody bylo před namočením papíru přidánohydrofobizační činidlo tvořené stearátem zinečnatým. Nakonecbylo těmto namočeným papírovým vláknům přidáno vápno CaOH2v množství 1 kg a křemenná moučka SiO2 v množství 0,65 kg.Tyto přísady byly suché a smíchané. Poté byla hmota zahřívá-na v autoklávu při teplotě 210 °C až 220 °C při tlaku nasy-cené páry, to znamená asi 19 - 23 barů. Vzniklo pevné těle- -3 so s hustotou asi 400 kg.m , které pak bylo ještě dosušeno. i.....Izolační materiál -dobře izoloval teplo a měl'velice drobné -—^otevře né^póry^-rMarteriá-l-^se^dá—lept^a dá se použít jako—- tepelně izolační materiál'nebo materiál k tlumení kročejové-ho hluku. Do materiálu lze rovněž přidávat vhodné ochrannélátky proti ohni, např. kyselinu boritou, borax nebo tetra- .......... fosforečnan sodnýa to např. v množství . 10 A hmotnosti,. ..... vztaženo na papírovou vlnu. V autoklávu dochází pouze k tvrzení. Zbývající neváza-ná voda se odstraní dosušením, např. v topné skříni, odpa-řením. Přitom rovněž vznikají v materiálu jemné póry. Tolze vysvětlit tím, že na povrchu papírových vláken ulpívávelké množství mikroskopických částeček vody, která po odpa-ření ponechává v izolačním materiálu velmi jemné póry, vy-volávající dobré izolační a tlumicí vlastnosti. Z toho vy-plývá rovněž, že použitelné množství vody je v jistých me-zích variabilní: musí se přidat alespoň takové množstvívody, aby stačilo k vázání kalcitu.Paper wool was produced from the old paper in a conventional manner and consisted of lightly felted paper fibers. 1.4 kg of these paper fibers were soaked in 4.5 liters of water, and zinc stearate hydrophobizing agent was added to the water prior to soaking the paper. Finally, lime CaOH2 was added to these soaked paper fibers in an amount of 1 kg and 0.65 kg of SiO2 quartz flour. These ingredients were dry and mixed. Thereafter, the mass was heated in an autoclave at 210 ° C to 220 ° C at a saturated steam pressure, i.e. about 19-23 bar. A solid body-3s was formed with a density of about 400 kg.m, which was then dried. The insulating material has a good insulated heat and has very small open porosity and can be used as a heat insulating material or material. for impact sound absorption. Suitable flame retardants such as boric acid, borax, or tetra-sodium phosphate may also be added to the material, e.g. 10 A weight ,. ..... related to paper wool. There is only curing in the autoclave. Remaining unbound water is removed by drying, eg in a heating cabinet, by evaporation. Fine pores are also produced in the material. It can be explained by the fact that a plurality of microscopic water particles adhering to the surface of the paper fibers, which, after evaporation, leave very fine pores in the insulating material, requiring good insulation and damping properties. It also implies that the usable amount of water is variable in certain respects: at least the amount of water must be added to make calcite bound.
Také množství papírových vláken je proměnlivé: totomnožství ovlivňuje jednak tlumicí vlastnosti a jednak pev-nost izolačního materiálu, který lze vyrobit s výhodou veformě desek.Also, the amount of paper fibers is variable: the amount affects both the damping properties and the strength of the insulating material which can be produced preferably with the shape of the plates.
Protože na povrchu materiálu je vápno případně kalcit,drží na něm velmi dobře omítka.Because lime or calcite is on the surface of the material, it keeps the plaster on it very well.
