Abstract
Official abstract text for this publication.
A polyurethane composition comprising an aldehyde scavenger, a polyurethane product, and a process for making polyurethane foam are disclosed. The scavenger compounds can reduce, if not eliminate, the emissions of aldehydes from polyurethane foams. The scavenger compounds comprise at least one member selected from the group consisting of: phenol or substituted phenol, a 1,3-dicarbonyl compound, a polyamine bearing a 1,3-propanediamino function, melamine, a 1,2-diaminocycloalkane, an ammonium salt; a compound containing the bisulfite anion, titanium dioxide and aminosiloxane.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising at least one aldehyde scavenger, at least one polyol, water and at least one amine catalyst, wherein the at least one aldehyde scavenger comprises at least one polyamine bearing a 1,3-propanediamino function; wherein the at least one polyamine is selected from the group consisting of N′N′-diphenylpropanediamine, 1-Benzyl-1,3-propanediamine, isotridecyloxypropyl-1,3-diaminopropane, dodecyloxypropyl-1,3-diaminopropane, and hexyloxypropyl-1,3-diaminopropane; and wherein the aldehyde scavenger is present in an amount of about 0.05 parts per hundred parts of the at least one polyol to 2.0 parts per hundred parts of the at least one polyol. 2. The composition of claim 1 further comprising at least one diluent. 3. A composition comprising at least one aldehyde scavenger, at least one amine catalyst and at least one diluent, wherein the aldehyde scavenger comprises at least one polyamine bearing a 1,3-propanediamino function; wherein the at least one polyamine is selected from the group consisting of NW′-diphenylpropanediamine, 1-Benzyl-1,3-propanediamine, isotridecyloxypropyl-1,3-diaminopropane, dodecyloxypropyl-1,3-diaminopropane, and hexyloxypropyl-1,3-diaminopropane. 4. A method for producing polyurethane foam, the method comprising reacting at least one polyol and at least one diisocyanate in the presence of: 1) at least one blowing agent, 2) at least one amine catalyst, and 3) the composition of claim 1 . 5. A method for producing polyurethane foam, the method comprising reacting 1) at least one polyol, 2) at least one blowing agent, 3) at least one amine catalyst, and 4) the composition of claim 1 , and contacting with at least one polyisocyanate thereby reacting the polyol and polyisocyanate to produce the polyurethane foam.
