THREE COMPONENT COMPOSITION FOR THE MANUFACTURE OF POLYURETHANE CEMENTITIOUS HYBRID FLOORING OR COATING WITH IMPROVED SURFACE GLOSS |
摘要 |
The present invention relates to a three component composition consisting of a polyol component (A) comprising at least two polyols, one with high and one with low molecular weight, and water, a polyisocyanate component (B) comprising a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2.5, or a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2 and at least one further polyol with an amount of between 1% and 30% based on the weight of said polyisocyanate component (B), wherein said MDI product and said polyol have reacted at least partially, and a powder component (C) comprising at least one hydraulic binder, preferably cement and/or calcined paper sludge, preferably a calcium compound selected from calcium hydroxide and/or calcium oxide, and optionally one or more aggregates. Polyurethane cementitious hybrid flooring or coating systems having glossy/semiglossy surfaces, good workability and outstanding mechanical properties can be achieved. Blister formation can be avoided. |

1. Three component composition consisting of
a) a polyol component (A) comprising
at least one polyol P1a with an average molecular weight of 800 to 30′000 g/mol, preferably 850 to 20′000 g/mol, more preferably 900 to 10′000 g/mol, andat least one polyol P1b with an average molecular weight of 48 to 800 g/mol, preferably 60 to 600 g/mol, more preferably 60 to 400 g/mol, most preferably 60 to 300 g/mol, andwater, and b) a polyisocyanate component (B) comprising
a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2.5, ora methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2 and at least one polyol P2 with an amount of between 1 and 30%, preferably between 5 and 25%, more preferably between 10 and 20% by weight, based on the weight of said polyisocyanate component (B), wherein said MDI product and said polyol P2 have reacted at least partially, and c) a powder component (C) comprising at least one hydraulic binder, preferably cement and/or calcined paper sludge. |
