Description
Tento vynález sa týká stavebnéj hmoty aleho maltoviny, najmá na povrchové a vodotěsné úpravy. .The present invention relates to a building material of mortar, in particular for surface and waterproof finishes. .
Pre povrchové úpravy, pri ktorých sa požaduje 1’ahká aplikácia, napr. jednoduchým náterom cementovej farby na povrch betódu a zároveň sa požaduje biely alebo iný jasný farebný odtieň nepostačuje použitie zmesi komerčnéhe portlandského cementu, vody a připadne pigmentu, zvláSť vtedy, ak je popři farebnom účinku vyžadovaná vodotěsnost! alebo trvanlivost! voči pdsobeniu klimatických faktorov. Ku komerčnému portlandskému cementu, například bielemu, sa pridávajú hydrofobizačné přísady, ako je napr. stearan vápenatý, hygroskopické soli ako je napr. chlorid vápenatý alebo sodný a retenčně přísady, ako je napr. kaseín a niekedy aa přidává aj vápno. Tieto však nezabezpečujú vodotěsnost! nátěru cementovej farby. Zatvrdnutá vrstva nátěru například ako cementovej farby zo zmesi cementu,vody a připadne s přidáním horeuvedených přísad, alebo fasádněj povrchovéj úpravy ako malty obsahujúcej aj plnivo prepúSťa tlakovú vodu. V ddsledku objemových zmien mdžu vznikat! jemné trhlinky, ktoré znižujú trvanlivost! a estetický účinok v případe vystavenia pdsobeniu klimatických faktorov. Řrídavok mletého alebo neupraveného popolčeka nie je vhodný pre jeho farbiaci účinok, znehodnocujúci biele alebo iné jasné či pastelové farebné odtiene, vzniklé přidáním malého množstva anorganického pigmentu k bielemu cementu.For coatings that require a light application, e.g. a simple coat of cement paint on the surface of the concrete while at the same time requiring a white or other clear color shade is not sufficient to use a mixture of commercial Portland cement, water and possibly a pigment, especially if waterproofing is required in addition to the color effect! or durability! against the effects of climatic factors. To commercial Portland cement, for example white, hydrophobic additives such as e.g. calcium stearate, hygroscopic salts such as e.g. calcium or sodium chloride and retention aids such as e.g. casein and sometimes aa adds lime. However, these do not ensure water tightness! cement paint. The hardened coating layer, for example, as a cement paint from a cement / water mixture and optionally with the addition of the above-mentioned additives, or a facade finish such as a mortar containing also a filler, permits pressurized water. Volume changes may arise! fine cracks that reduce durability! and aesthetic effect when exposed to climatic factors. The addition of ground or untreated fly ash is not suitable for its coloring effect, devaluing white or other bright or pastel color shades resulting from the addition of a small amount of inorganic pigment to the white cement.
Uvedené nedostatky odstraňuje maltovina podl’a vynálezu.These deficiencies are overcome by the mortar according to the invention.
Jej podstata spočívá v tom, že pozostáva zo zmesiIt consists essentially of a mixture
- 100 hmotnostných dielov cementu- 100 parts by weight of cement
- 3 až 40 dielov mletého vápenca- 3 to 40 parts of ground limestone
- 0,2 až 2 hmotnostných dielov dispergačného prostriedku, s výhodou pozostévajúceho z kondenzačného produktů formaldehydu a sulfonovanej aromatickej a/alebo heterocyklickej zlúčeniny pričom zrnenie celej zmesi je také, že obsahuje najmenej %, s výhodoz 90 % častíc menSích ako 40 /un .0.2 to 2 parts by weight of a dispersant, preferably consisting of the condensation products of formaldehyde and a sulfonated aromatic and / or heterocyclic compound, wherein the grain of the whole mixture is such that it contains at least%, preferably 90% of particles smaller than 40 µm.
%, s výhodou 80 % častíc menSích ako 30 ^um %, s výhodou 65 % častíc menších ako 20^um %, s výhodou 40 % častíc menších ako 10 um%, preferably 80% of particles smaller than 30 µm%, preferably 65% of particles smaller than 20 µm%, preferably 40% of particles smaller than 10 µm
2 a měrný povrch zmesi je najmenej 4.300 cm /g, s výhodou 5.800 cm /g.2 and the specific surface area of the mixture is at least 4,300 cm / g, preferably 5,800 cm / g.
Ako dispergačný prostriedok, s výhodou pozostávajúci z kondenzačného produktu formaldehydu a sulfonovanej aromatickej a/alebo heterocyklickej zlúčeniny, je vhodná napr. vodorozpuetná sulfonovaná melaminformaldéhydová živica alebo dinaftylmetándieulfonan sodný. V maltovine podía vynálezu mfiže byť obeiahnutý křemičitý úlet v množstve 0,01 až 6 dielov hmotnostných, počítané na 100 hmotnostných dielov cementu. Tento úlet vzniká ako odpad pri výrobě kremíka a obsahuje výše 90 % amorfného kysličníka křemičitého. Má bielu farbu a je velmi jemný. Úlet mdže byť ečasti alebo úplné nahradený siloxidom, čo je v podstatě taktiež biely jemný amorfný kysličník křemičitý.Suitable dispersants, preferably consisting of a condensation product of formaldehyde and a sulfonated aromatic and / or heterocyclic compound, are e.g. water-soluble sulfonated melamine-formaldehyde resin or sodium dinaphthylmethanediulfonate. In the mortar according to the invention, the silica drift can be contained in an amount of 0.01 to 6 parts by weight, calculated per 100 parts by weight of cement. This drift is produced as silicon waste and contains above 90% amorphous silica. It is white and very soft. The drift may be partially or completely replaced by siloxide, which is also essentially white fine amorphous silica.
Ak je potřebné zvBčSiť hrůbku nanášenéj vrstvy, je účelné pridať do maltoviny, počítané na 100 hmotnostných dielov cementu, 1 až 500 dielov plniva, s výhodou křemičitého piesku alebo vápencovéj drvy.If it is necessary to increase the depth of the deposited layer, it is expedient to add to the mortar, calculated on 100 parts by weight of cement, 1 to 500 parts of a filler, preferably silica sand or limestone grit.
Zloženie maltoviny podía vynálezu sa mdže modifikovat přísadami, ako sú přísady hydrofobizačná, například stearan vápenatý alebo metyleilanolát sodný;, ďalej přísadou dieperžie, například kopolyméru vinylacetátetylénového, metylmetakrylát-akrylového, alebo ich zmesí, s výhodou vo formě redispergovatelného prášku; přísadou hygroekopických solí, ako je chlorid vápenatý alebo sodný; přísadou vodorozpustného derivátu celulózy; přísadou kaseínu a anorganického pigmentu.The mortar composition according to the invention can be modified with additives such as hydrophobicizing agents, for example calcium stearate or sodium methylanilanolate; furthermore with a dessicant, for example a vinyl acetate ethylene, methyl methacrylate acrylic copolymer, or mixtures thereof, preferably in the form of a redispersible powder; the addition of hygroecopic salts such as calcium or sodium chloride; adding a water-soluble cellulose derivative; by adding casein and an inorganic pigment.
fialšie zníženie nasiakavosti a celkovej pórovitosti sa dosiahne, ak maltovina podía vynálezu obsahuje, počítané na 100 dielov hmotnostných cementu, 0,02 až 45 dielov termoeetickej živice, vznikajúcej polymerizéciou a/alebo polykondenzáciou v priebehu tuhnutia a tvrdnutia maltoviny z monomérhych zložiek alebo predkondenzátov. Takéto živice sú reakčné produkty vzniklé například z aldehydu alebo alkoholu a anorganickej zlúčeniny obsahujúcej aminoskupiny, ako je Zivica z furfurylalkoholu a anilínhydrochloridu, alebo podía če. autorského osvedčenia č. 193693, kde je popísaná živica z 2-furalaldehydu a kyseliny sulfanilovej alebo jej vápenatej soli. Pře přípravu suchých omiet' - 3 kových zmesi je účelné, aby zložky, z ktorých vzniká živica, boli vo formě suchého práškového produktu například keď sa použije predkondenzát 2-furylaldehydu a kyseliny sulfanilovej podTa čs. autorského osvedčenia č. 193693. Uvedenými príkladmi zďaleka nie sú vyčerpané možnosti modifikácie maltoviny podTa vynálezu róznymi živicami typu termosetu a je možné použiť aj modifikáciu ďalšími druhmi živíc, ako sú napr. termosetické živice, vzniklé vytvrdnutím emulzie epoxidových živíc alebo polyesterových živic alebo zo solí kyseliny akrylovej alebo metakrylovej alebo iných nenasýtených organických zlúČenín. .a more violent reduction in absorbency and total porosity is obtained if the mortar according to the invention contains, calculated per 100 parts by weight of cement, 0.02 to 45 parts thermoeetic resin resulting from polymerization and / or polycondensation during solidification and hardening of the mortar from monomer components or precondensates. Such resins are reaction products formed, for example, from an aldehyde or an alcohol and an inorganic compound containing an amino group, such as a furfuryl alcohol and aniline hydrochloride resin, or a fraction thereof. of the author's certificate no. 193693, which discloses a resin of 2-furalaldehyde and sulfanilic acid or a calcium salt thereof. For the preparation of dry plaster compositions, it is expedient for the resin-forming components to be in the form of a dry powder product, for example when 2-furylaldehyde and sulfanilic acid precondensate according to U.S. Pat. of the author's certificate no. These examples are far from exhausting the possibilities of modifying the mortar according to the invention with different thermosetting resins, and it is also possible to use modifications with other types of resins, such as e.g. thermosetting resins formed by curing an emulsion of epoxy resins or polyester resins or from salts of acrylic or methacrylic acid or other unsaturated organic compounds. .
