Description

Die Hauptanmeldung 1 671 017 betrifft die Herstellung eines Baumaterials, bestehend aus Harz, anorganiaohen Bindemitteln und gegebenenfalls Füllstoffen, indem man 0,01 bis 30 Gewichtsprozent, bezogen auf das anorganische Bindemittel, einer Lösung an sulfit- oder sulfonsäuremodifiziertem Harz auf der Basis eines Amino-s-triazins mit mindestens zwei NH2-Gruppen mit so viel erdalkalihaltigen, anorganischen Bindemitteln umsetzt, daß pro Mol Säuregruppe mindestens 1 Mol Erdalkali zur Verfügung steht, und diese Lösung zu den entsprechenden anorganischen Bindemitteln und gegebenenfalls Füllstoffen zusetzt.The main application 1 671 017 relates to the production of a building material consisting of resin, inorganic binders and optionally fillers by adding 0.01 to 30 percent by weight, based on the inorganic binder, of a solution of sulfite- or sulfonic acid-modified resin based on an amino s-triazines with at least two NH 2 groups are reacted with inorganic binders containing alkaline earth metal that at least 1 mole of alkaline earth metal is available per mole of acid group, and this solution is added to the corresponding inorganic binders and optionally fillers.

Die vorliegende Erfindung stellt eine weitere Ausbildung des Gegenstandes der Hauptanmeldung insofern dar, als man das sulfit- oder sulfonsäuremodifizierte Harz aus Amino-s-triazin mit mindestens zwei NH^-Gruppen und Formaldehyd in ficier oder gebundener Form in der Mischung aus inorganischcm Bindemittel, Wasser und gegebenenfalls Füllstoffen unmittelbar erzeugt.The present invention represents a further development of the subject matter of the main application in this respect represent, than the sulfite or sulfonic acid-modified resin from amino-s-triazine with at least two NH ^ groups and formaldehyde in ficier or bound Form in the mixture of inorganic binder, water and optionally fillers directly generated.

Das Harz wird in diesem Falle erst während des Erhärtungsprozesses gebildet und bewirkt so die gewünschte Festigkeitssteigerung des Baumaterials. Es ist also eine getrennte Herstellung der Harzlösung überflüssig. In this case, the resin is only formed during the hardening process and thus produces the desired effect Increased strength of the building material. Separate preparation of the resin solution is therefore unnecessary.

1. Zu einer Mischung aus 100 Gewichtsteüen Portlandzement 275 und 300 Gewichtsteüen Sand wurden, gelöst im Anmachwasser, 1,3 (2,6) Gewichtsteile Ammelin, 1,0 (2,0) Gewichtsteile Ätznatron, 0,6 (1,2) Gewichtsteile Formaldehyd und 0,1 (0,2) Gewichtsteile Rongalit zugesetzt. Nach 28 Tagen wurde die Biegezug- und Druckfestigkeit bestimmt.1. To a mixture of 100 parts by weight of Portland cement 275 and 300 parts by weight of sand were dissolved in the mixing water, 1.3 (2.6) parts by weight of ammeline, 1.0 (2.0) parts by weight of caustic soda, 0.6 (1.2) parts by weight of formaldehyde and 0.1 (0.2) parts by weight Rongalit added. The flexural tensile strength and compressive strength were determined after 28 days.

Gegenüber dem Beton ohne Zusatz wurde die Biegezugfestigkeit um 36% (76%) und die Druckfestigkeit um 55% (65%) erhöht.Compared to the concrete without additive, the flexural strength was increased by 36% (76%) and the compressive strength increased by 55% (65%).

2. 100 Gewichtsteile Portlandzement 275, 300 Ge wichtsteile Sand, 1,3 Gewichtsteile Ammelin, 1,0 Gewichtsteile Ätznatron und 2,5 Gewichtsteile Rongalit wurden trocken gemischt.

3. Zu einer Mischung aus 100 Gewichtsteüen Portlandzement 275 und 300 Gewichtsteüen Sand wurden, gelöst im Anmachwasser, 1,2 (2,4) Gewirhtsteile ß-Sulfopropioguanamin, 0,5 (1,0) Gewichtsteile Ätznatron und 0,5 (1,0) Oewichtsteile Formaldehyd zugesetzt und nach 28 Tagen die Biegezug- und Druckfestigkeit bestimmt.3. To a mixture of 100 parts by weight of Portland cement 275 and 300 parts by weight of sand, dissolved in the mixing water, 1.2 (2.4) parts by weight of ß- sulfopropioguanamine, 0.5 (1.0) parts by weight of caustic soda and 0.5 (1, 0) Parts by weight of formaldehyde were added and the flexural tensile strength and compressive strength were determined after 28 days.

Gegenüber dem Beton ohne Zusatz wurde die Biegezugfestigkeit um 5% (22%) und die Druckfestigkeit um 19% (52%) erhöht.Compared to the concrete without additive, the flexural tensile strength was 5% (22%) and the compressive strength increased by 19% (52%).

4. 100 Gewichtsteile Portlandzement 275, 300 Gewichtsteile Sand, 2,4 Gewichtsteile /?-Sulfopropioguanamin, 1,0 Gewichtsteile Ätznatron und 4,3 Gewichtsteile Rongalit wurden trocken gemischt. Nach Zugabe von 50 Gewichtsteüen Wasser wurden Probekörper hergestellt und nach 28 Tagen Biegezug- und Druckfestigkeit bestimmt.4. 100 parts by weight Portland cement 275, 300 parts by weight sand, 2.4 parts by weight /? - sulfopropioguanamine, 1.0 parts by weight of caustic soda and 4.3 parts by weight of Rongalit were dry mixed. After adding from 50 parts by weight of water test specimens were produced and after 28 days flexural tensile and compressive strength certainly.
