Catalysts are widely used in the production of polyurethanes by reaction with polyisocyanates, polyols, and in some cases other components; catalysts are used to balance multiple simultaneous reactions during the production process. It is thought that they act competitively. One of the reactions that occur in the polyurethane manufacturing process is the reaction of polyincyanate and polyol, which forms polyurethane and results in chain extension and increased viscosity. Another reaction is the reaction of polyisocyanates with amines to form urea bonds.

Yet another reaction is the reaction of polyisocyanates with water, which generates foam due to the evolution of carbon dioxide. This reaction of polyincyanate with water is not necessarily essential when other blowing agents are used. In order to obtain an excellent form structure through these reactions, each reaction must be balanced; if the formation of the form is too fast compared to the chain elongation, the form will collapse, and conversely, the chain will If the elongation is too fast compared to the generation of the foam, the generation of the foam will be restricted. Control of these reactions depends on the selection of reaction conditions, but
The choice of catalyst is most important.

Because polyurethane foam is easy to mold, its uses have expanded to include automobile parts, furniture, and footwear, and polyurethane is now expected to have harsh properties. In other words, ■The molding time is short, and ■The molding time is short. M i
, good fluidity during H fat formation, ■ low density of the resulting polyurethane foam, ■ absence of voids, ■ low brittleness, and ■ ability to adhere to adherend when integrally molded. The polyurethane is easy to use, (1) the resulting polyurethane does not burn or crack, (2) the odor is small, and the performance meets the required edges, but it was impossible to satisfy all of these requirements. For example, if a large amount of catalyst is added to shorten the molding time, the fluidity during foaming resin will be lost, resulting in poor filling properties, and the resulting polyurethane foam will be prone to discoloration and cracks. It is not possible to achieve these required performances at the same time. Furthermore, quinta-class amines, which are conventionally widely used catalysts, are indispensable in the production of polyurethane foams using water as a blowing agent. It has significantly reduced its value.

N'-tetramethyl-2,2'diaminodiethyl ether, but these give too much priority to the foaming reaction, which delays the late reaction (curing reaction after foaming stops in urethane foam curing) and prevents complete curing. It takes a long time. In addition, if the amount added is increased, foaming in the initial reaction (up to 50% of the final volume in urethane foam curing) will give too much priority to foaming, and foams with low viscosity will be used for injection into complex shapes with small gaps and many obstacles. During molding, bubbles break and voids are generated, which causes a decrease in strength and insulation properties.
