Tento vynález sa zuoberá spdsobom výroby stavebnej hmoty.The present invention relates to a method for producing a building material.
Na modifikáciu pórov:.·;; Ětruktúry a fyzikélno-mechanických vlastností zatvrdnutýchstavebných hm&t z anorganických spojiv sa používajá vo vodě rozpustná organické monomery,ktoré v priebehu tuhnutia a tvrdnutia vytvárajá, spravidla polykondenzaínými reakciami,nerozpustný polymer. Antonova a kol. popísala stabebná hmotu (Strojitelnyje materiály,For pore modification:. The structure and the physico-mechanical properties of the hardened structural inorganic binders are water-soluble organic monomers which, during solidification and hardening, form an insoluble polymer, usually by polycondensation reactions. Antonova et al. described the stagnant mass (Strojitelnyje materials,
2. 7/1964, str 5-6), v ktorej ako anorganické spojivo bol použitý portlandský cement aako vo vodě rozpustné organické monomery anilínhydrochlorid a furfuralalkohol, priíom v prieběhu hydratácie cementu vzniká nerozpustný organický polymer. V autorskom osvedíení ČSSH 6. 193 693 já popísaná stavebná hmota, ktorá obsahuje ako anorganické spojivo například portlandský cement a ako vo vodě rozpustné organické monomery fural a rozpustná, napříkladvápenatá, sol' kyseliny sulfanilovej.7/1964, pp 5-6), in which Portland cement was used as the inorganic binder, and aniline hydrochloride and furfuralal alcohol as water-soluble organic monomers was used, the insoluble organic polymer being formed during the cement hydration. ČSSH 6,193,693 I describes a building material that contains, for example, Portland cement as an inorganic binder and fural and soluble, for example, calcium-soluble, sulfanilic acid salt as water-soluble organic monomers.
Nerozpustný polymer m6že vzniknáť v priebehu tvrdnutia stavebnej hmoty aj z furalua močoviny (karbamidu). tívedené stavebné hmoty sa vyrábajá zmieSaním jednotlivých zložiekso zámesovou vodou, načo sa nechajá vo vhodnej formě alebo debnení zatvrdnát pri běžnýchteplotách. 7 stavebnej hmotě podl’a Antonovej a kol. zostáva aj po 90 dňoch tyrdnutia volný,nezreagovaný furfuralalkohol v množstve 8 až 12 % z pSvodne přidanéj dávky. SkáSkami bolozlstené, že v zásaditom prostředí hydrátujáceho cementu vzniká Cannizzarovou reakciouz řas ti furalu fuftfurylalkohol a vápenatá sol’ kyseliny pyroslizovej 2 (TJL-ch2o + OH- —* (31---ch2oh + O-coo-0 0 0 7 stavebných hmotách, obsahujácich ako sjáojivo cement na báze portlandského slínkua fural ako jeden z monomerov tvoriacich polymer, zostáva aj po 90 dňoch tvrdnutia priběžných teplotách voTný, nezreagovaný furfurylalkohol v množstve odpovedajácom až 12 %pCvodne přidaného furalu. Furfurylalkohol je toxický. Stavebné hmoty obsahujáce zbytkyvolného, nezreagovaného furfurylalkoholu sa nesmá použit tam, kde sa požaduje hygienickánezávadnost. Pevnosti v tahu zatvrdnutých stavebných hmdt s obsahom týchto polymercv vyro-bená tvrdnutím při běžných teplotách sá negativné ovlivňované vlhkostou. Ak se při výroběstavebnej hmoty použije urýchlovanie tvrdnutia preteplovaním, dochádza v dfisledku nega-tivného vplyvu organických monomerov a vznikajáceho polymeru k znižovaniu pevností v po-rovnaní so stavebnými hmotami vyrobenými bez přídavku vo vodě rozpustných monomerov.The insoluble polymer may also be formed during the hardening of the building material and from the fural and urea (carbamide). The thinned building materials are produced by mixing the individual components with water, and then, in a suitable form or formwork, are allowed to harden in conventional temperatures. 7 building material under Antonová et al. the free unreacted furfuralal alcohol remains in the amount of 8-12% of the initially added dose, even after 90 days of thyroid. Rocks have been mistaken that in alkaline environments of hydrating cement, Cannizzar reaction produces algae fural fuftfuryl alcohol and calcium salt of pyrosulphonic acid 2 (TJL-ch2o + OH- - * (31 --- ch2oh + O-coo-0 0 0 7 building materials, containing, as a polymer, Portland clinker cement and fural as one of the polymer-forming monomers, even after 90 days of hardening, the relative temperatures of free, unreacted furfuryl alcohol remain in the amount of up to 12% of the originally added fural furfuryl alcohol is toxic. Tensile strengths of hardened building materials containing these polymers produced by hardening at normal temperatures are adversely affected by moisture, and if acceleration hardening is used to accelerate the build-up of the building material, the organ and monomers and the resulting polymer to reduce the strengths compared to those produced without the addition of water-soluble monomers.
Uvedené nedostatky odstraňuje spfisob výroby stavebnej hmoty podlá vynálezu. Jeho pod-stata spočívá v tom, že jednotlivé zložky stavebnej hmoty - anorganické spojivo, najmenejjeden vo vodě rozpustný monomer a připadne plnivo a/alebo známe modifikujáce anorganickéa/alebo organické přísady a/alebo příměsi - zmieSajá so zámesovou vodou a po vytvrdnutí přiběžných teplotách sa stavebná hmota ohřeje na teplotu najmenej 50 °C, s výhodou najmenej100 °C.The above mentioned drawbacks are eliminated by the method of production of the building material according to the invention. It is based on the fact that the individual components of the building material - an inorganic binder, at least one water-soluble monomer and optionally a filler and / or known modifying inorganic / or organic additives and / or admixtures - are mixed with the mixing water and the building material heats to a temperature of at least 50 ° C, preferably at least 100 ° C.
Vhodné dávky organických monomerov sá v rozsahu 1 až 30 % z hmotnosti anorganickéhospojiva.Suitable doses of organic monomers are in the range of 1 to 30% by weight of the inorganic bond.
Pri výrobě stavebnej hmoty postupom podlá vynálezu sa m0žu použit ako anorganickéspojivá, například cementy na báze portlandského slínku, ako je portlandský, troskoportland-ský alebo puzolánový portlandský cement, alebo zmesi portlandského cementu s vápnom. Akovo vodě rozpustné monomery sa m8žu použit například kombinácie: - fural - rozpustná sol kyseliny sulfanilovej - furfurylalkohol - anilínhydrochlorid - formaldehyd - rozpustný fenolát. 3 232328In the production of the building material according to the invention, it can be used as inorganic bonding agents, for example Portland clinker-based cements such as Portland, troscortland or pozzolanic Portland cement, or mixtures of Portland cement with lime. As water-soluble monomers can be used, for example, combinations of: - fural - soluble salt of sulphanilic acid - furfuryl alcohol - aniline hydrochloride - formaldehyde - soluble phenolate. 3 232328
Ako známe modifikujúee anorganické přísady sa m6žu použit například tesniace přísa-dy, ako je bentonit, urýchlujúce přísady, ako je chlorid vápenatý a podobné. Ako známeorganická přísady sa mdžu použit například přísady plastifikačné. Ako známe příměsi jemožná použit například neupravený alebo mletý popolček. Výhody výroby stavebnej hmoty sp8sobem podlá vynálezu ukazuje nasledujúci příkladrealizácíe: Z troskoportlandského cementu triedy SPC 325, mletého popolčeka s měrným povrchom 2-1 800 m .kg sulfitových výpalkov a organických monomerov technickej čistoty boli připra- vené 3 malty zloženia podl’a tabulky 1.As a known modifying inorganic additive, for example, sealants such as bentonite, accelerating additives such as calcium chloride and the like can be used. As a known organic additive, for example, plasticizing additives can be used. For example, untreated or ground fly ash may be used as known additives. The advantages of producing the building material according to the invention are shown in the following example: The trortortland cement of SPC 325 class, ground ash with a surface area of 2-1 800 m. Kg of sulphite stillage and organic monomers of technical purity were prepared with 3 mortars of the composition according to Table 1.
