Abstract

A PROCESS FOR PREPARING A CELLULAR POLYURETHANE-POLYUREA COMPOSITION HAVING A RESISTANT, STRONG MOLDING SKIN THAT REMAINS BONDED TO SAID CELLULAR COMPOSITION AND EXHIBITS NO VISIBLE POROSITY TO THE NAKED EYE, AND A FOAM DENSITY GREATER THAN 150 GRAMS PER LITER BY (A) PREPARING A REACTION MIXTURE BY MIXING A POLYISOCYANATE, A POLYOXYALKYLENE POLYOL HAVING AN AVERAGE MOLECULAR WEIGHT BETWEEN ABOUT 130 AND 6,000, AN AROMATIC POLYAMINE, A FOAMING AGENT, AND A CATALYST FOR THE POLYURETHANE-POLYUREA REACTION THE NH2/OH RATIO BEING BETWEEN 0.3 AND 5/1, THE NCO/OH+NH2 RATIO BEING BETWEEN 0.9 AND 2/1, THE AMOUNT OF FOAMING AGENT BEING FROM 0.5 TO 50 WEIGHT PERCENT OF THE WEIGHT OF THE REACTION MIXTURE, THE AMOUNT OF CATALYST BEING FROM 0 TO 2 WEIGHT PERCENT OF THE COMBINED WEIGHT OF SAID POLYOL AND SAID AROMATIC POLYAMINE, THE MIXING BEING CARRIED OUT AT A TEMPERATURE IN THE RANGE OF ABOUT 0* TO 140*C.; (B) INTRODUCING THE REACTION MIXTURE INTO A MOLD, WHICH IS AT A TEMPERATURE BETWEEN ABOUT 20* AND 150*C., WHEREIN THE REACTION AND EXPANSION TAKE PLACE; (C) AFTER COMPLETION OF THE EXPANSION, PLACING THE MOLD IN AN OVEN MAINTAINED AT A TEMPERATURE IN THE RANGE OF ABOUT 20* TO 140*C.; AND (D) AFTER A PERIOD OF FROM ABOUT 5 TO 30 MINUTES REMOVING THE MOLD FROM SAID OVEN AND DEMOLDING THE RESULTING CELLULAR COMPOSITION.

Q Int. Cl. C08g 22/46 U.S. Cl. 26445 N0 Drawing. 17 Pages Specification A process for preparing a cellular polyurethane-polyurea composition having a resistant, strong molding skin that remains bonded to said cellular composition and exhibits no visible porosity to the naked eye, and a foam density greater than 150 grams per liter by (A) preparing a reaction mixture by mixing a polyisocyanate, a polyoxyalkylene polyol having an average molecular weight between about 130 and 6,000, an aromatic polyamine, a foaming agent, and a catalyst for the polyurethane-polyurea reaction the NH /OH ratio being between 0.3 and 5/1, the NCO/OH+NH ratio being between 0.9 and 2/ 1, the amount of foaming agent being from 0.5 to 50 weight percent of the weight of the reaction mixture, the amount of catalyst being from 0 to 2 Weight percent of the combined weight of said polyol and said aromatic polyamine, the mixing being-carried out at a temperature in the range of about 0 to 140 C.;
(B) introducing the reaction mixture into a mold, which is at a temperature between about 20 and 140 0, wherein the reaction and expansion take place;
(C) after completion of the expansion, placing the mold in an oven maintained at a temperature in the range of about 20 to 140 C.; and
(D) after a period of from about 5 to 30 minutes removing the mold from said oven and demolding the resulting cellular composition.
