Catalyst, catalyst composition to produce polyurethane foam, polyurethane composition, polyurethane foam product and method to prepare a polyurethane foam

摘要

Is a catalyst composition to produce polyurethane foam, and the catalytic composition includes a compound which has a general formula r1r2r3n, in which each of the R1, R2 and R3 is selected independently from the group consisting of: one compound according to The formula (i),In which n = 1 to 5; and R4, R5 and R6 are each independently hydrogen, methyl, ethyl and propyl groups; hydrogen, a compound group alkyl C1 -c6, a compound cyclalkyl group C1 -c6, a compound of alkyl group C1 -c6, a n alkyl group compound C1 -c6, a n alkyl group compound 1 -c6, and a compound of aralquila group C1 -c6, each group being replaced or not replaced; in which at least one of R1, R2 and R3 is a compound according to the formula (i). A polyurethane composition and method to form a polyurethane foam are also revealed.
