FOAM POLYURETHANE COMPOSITION, METHOD OF PRODUCING FOAM POLYURETHANE AND CATALYST COMPOSITION USED THEREFOR Russian patent published in 2016 - IPC C08G18/18 C08G18/48 C08G18/76 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst composition used to produce foam polyurethane, containing at least one catalyst which does not release hazardous substances and tetraalkyl-guanidine of the formula , where R₁, R₂, R₃ and R₄ are independently C1-C10 alkyl groups and branched or straight isomers thereof, where the at least one catalyst which does not release hazardous substances includes bis-(N,N-dimethylaminopropyl)-amine and a compound selected from a group consisting of N-(dimethylaminoethyl)-N-(2-hydroxyethyl)-N-methylamine, 2-[N-(dimethylaminoethoxyethyl)-N-methylamino]ethanol and N,N,N'-trimethyl-N'-3-aminopropyl-bis(aminoethyl)ether. The invention also relates to a catalyst composition used to produce foam polyurethane, which contains about 70 wt % or more of N,N,N'-trimethyl-N'-3-aminopropyl-bis(aminoethyl)ether and about 30 wt % or less of tetramethyl-guanidine, and to a method of producing water-foamed low-density rigid foam polyurethane, which includes contacting at least one polyisocyanate with at least one polyol with isocyanate index of 20-100, in the presence of an effective amount of a composition of foaming substances, containing at least 75 wt % water, and an effective amount of the catalyst composition according to claim 1, where the rigid foam polyurethane has density of about 6 to about 16 kg/m³. The foam polyurethane composition contains at least one polyol, at least one isocyanate, an effective amount of a composition of foaming substances and an effective amount of a catalyst composition.

EFFECT: effective increase of the foam rising rate when producing water-foamed low-density foam material to avoid "creeping" of the foam material during spraying, while simultaneously maintaining good physical properties, reducing smell and preventing release of hazardous substances.
