| titleOfInvention | Foam polyurethanes, including lipid-based polyols |
| abstract | FIELD: chemistry. n SUBSTANCE: claimed invention relates to method of obtaining foam-polyurethane foam from lipid-based polyols. Described is method of obtaining polyurethane foam, which contains lipid-based polyol, including: (a) obtaining prepolymer by method, which includes the following stages: providing presence of lipid-based polyol, first quantity of multifunctional isocyanate and first quantity of, at least, one jellification catalyst; and combination of lipid-based polyol, isocyanate and first quantity of jellification catalyst with formation of polyol/isocyanate mixture; interaction of polyol/isocyanate mixture mainly without application of additional heating; with obtaining prepolymer, with prepolimer being mainly not in form of foam and having functional groups OH, which have not reacted, and having lower quantity of free monomer that has not reacted and dimeric polyols in comparison with polyol/isocyanate mixture; (b) obtaining polyurethane foam by method, which includes the following stages: combination of prepolymer from stage (a) with second quantity of multifunctional isocyanate and with foaming agent, and interaction of prepolymer, isocyanate and foaming agent with obtaining polyurethane foam; where firat quantity of multifunctional isocyanate constitutes from 0.01% to 33% of stoichimetric quantity of multifunctional isocyanate(s), which is required for interaction with present hydroxyl groups of polyol(s) in polyol/isocyanate mixture; where first quantity of isocyanate includes at least one of 4,4′-methylenebis(phenylisocyanate) (MDI) and tolueneisocyanate (TDI); and where lipid-based polyol includes sufficient quantity of lipid-based polyol so that the total quantity of lipid-based polyol in polyurethane foam constitutes not less than 10% with respect to the total quantity of polyol by weight in foam. n EFFECT: obtaining foam-polyurethane foam, possessing improved physical properties and residual compression deformation. n 13 cl, 1 dwg, 6 tbl, 57 ex |
