Description

This invention relates to materials and methods for producing materials. More specifically, this invention relates to polyurethane foams and premixes, and methods for producing polyurethane foams and premixes. Polyurethane foam is used in a wide variety of products. Such products exist in the automotive industry, the housing industry, other construction and manufacturing industries, and virtually everywhere else. Many of these known polyurethane foam products are manufactured by reacting polyisocyanates with polyols in the presence of additives. One such additive is chlorofluorocarbon, commonly known as CFC. CFCs are used as blowing agents, which vaporize as a result of the exothermic reaction, forming polymerized masses and creating foam. CFCs inevitably have the drawback of reducing ozone in the stratosphere and raising environmental concerns. The use of water as a blowing agent involves the production of CO2 from the reaction of the water with the polyisocyanate. Due to the environmental risks associated with the use of CFCs, the use of water as a blowing agent has become more common. However, the use of water as a blowing agent presents additional challenges. Tertiary amine catalysts are known to be used to promote foaming when the foaming agent is water. These tertiary amine catalysts selectively promote foaming or gelation in the manufacture of polyurethane foam products. If too much of the foaming tertiary amine catalyst is present in the process, CO2 will escape from the polyurethane foam product as foam, and the structure of the polyurethane foam product will collapse, for example, resulting in a broken or poorly defined cellular structure. The use of tertiary amine catalysts in the formation of polyurethane foam products was undesirable due to the hazards of tertiary amines. Tertiary amines are malodorous and highly volatile. Furthermore, they can pose safety and toxicity concerns. Therefore, it is desirable to have little to no tertiary amine emissions during use. To achieve this, known tertiary amine catalysts may contain isocyanate-reactive groups that allow the amine catalyst to be immobilized in the polyurethane polymer. However, the resulting product may have undesirable properties, for example, substantially decompose under accelerated aging with high temperature and humidity. Alternatively, using low vapor pressure, high molecular weight amine catalysts may require the use of large amounts of catalyst, thereby making the manufacturing cost exorbitant. Several known methods involve the use of additives for the manufacture of polyurethane products. For example, U.S. Patent No. 4,007,140 discloses N,N'-bis(3-dimethylaminopropyl)urea as a low-odor catalyst, which is thereby incorporated herein by reference in its entirety. U.S. Patents No. 4,338,408 and 4,433,170 disclose additives structurally related to bis(dimethylamino)ethyl ether as foaming catalysts, which are each incorporated herein by reference in their entirety. U.S. Patents No. 5,508,314, 5,559,161, and 5,633,293 disclose additives having amine catalysts containing a high amount of secondary alcohol to balance the activation of the active hydrogen-isocyanate reaction and the acceleration of the reaction between the isocyanate and the additive, which are each incorporated herein by reference in their entirety. The additives disclosed in the patents cited above do not improve wet aging properties. U.S. Patent No. 5,859,079 discloses an additive comprising N,N'-bis(3-dimethylaminopropyl)urea and 3-dimethylaminopropylurea in a predetermined ratio for controlling the flowability, airflow, and forces on the collapse properties of a polyurethane product, which is thereby incorporated herein by reference as a whole. U.S. Patent No. 6,114,403 discloses an additive comprising N,N'-bis(3-dimethylaminopropyl)urea and 3-dimethylaminopropylurea in a predetermined ratio for controlling the flowability and percentage of continuous cell content of a rigid polyurethane foam product, which is thereby incorporated herein by reference as a whole. The additives disclosed in the patents cited above do not improve wet aging properties. Known additives are used to manufacture water-foamed flexible polyurethane foam products. U.S. Patent No. 6,201,033 discloses an additive comprising tertiary aminoalkylurea and/or bis(tertiary aminoalkyl)urea in combination with either a tertiary amine gelling catalyst or a tertiary amine foaming catalyst, which is thereby incorporated herein by reference as a whole. U.S. Patent No. 6,232,356 discloses an additive comprising tertiary aminoalkylurea and/or bis(tertiary aminoalkyl)urea in combination with either a gelling catalyst or a foaming catalyst for improving the physical properties of the manufactured product, which is thereby incorporated herein by reference as a whole. The additives disclosed in the patents cited above do not improve wet aging properties. U.S. Patent No. 6,858,654 discloses additives for catalyzing a
