摘要： Disclosed is a method of adding a compound having at least one group selected from the group consisting of a carboxyl group, salts thereof, esters thereof and haloformyl groups or an acid anhydride, as a treating agent, to a resin decomposed substance prepared by decomposing a urethane bond of a urethane resin, and adding an epoxy resin or isocyanate compound to the product, to regenerate the resin. According to the present invention, reaction activity in producing a regenerated resin from a urethane resin decomposed substance is appropriately suppressed, and thus regeneration of a urethane resin can be carried out by easy procedures.

摘要： A novel method for decomposing urethane resin suppresses the generation of aromatic amines and facilitates the recycling of urethane resins. To decompose urethane resin, the method involves the use of a decomposing agent that has both an ability to cleave urethane bonds in a urethane resin and an ability to react with and thus capture an amine compound. The decomposing agent is preferably one that contains either at least one selected from carboxyl group, and a salt, ester and acid anhydride thereof, or at least one selected from isocyanate group and epoxy group.
摘要翻译：分解聚氨酯树脂的新方法抑制芳族胺的产生并促进聚氨酯树脂的再循环。为了分解聚氨酯树脂，该方法包括使用具有在聚氨酯树脂中分解氨基甲酸酯键的能力和与胺化合物反应并因此捕获胺化合物的能力的分解剂。分解剂优选含有选自羧基及其盐，酯和酸酐中的至少一种或选自异氰酸酯基和环氧基中的至少一种的分解剂。

摘要： A method of decomposing a thermosetting resin by a decomposer comprising the steps of: pre-heating the thermosetting resin up to a pre-heating temperature T0; kneading the pre-heated thermosetting resin together with a decomposer, and concurrently heating a mixture comprising the thermosetting resin and the decomposer up to a kneading temperature T1, thereby allowing a reaction to take place between the decomposer and the thermosetting resin to obtain a kneaded matter wherein the decomposer becomes consumed; and heating the kneaded matter to a maximum temperature T2 to thereby decompose the thermosetting resin; wherein the preheating temperature T0 is not higher than the boiling temperature of the decomposer; the kneading temperature T1 is not lower than the pre-heating temperature T0 but is lower than the thermal decomposition temperature of the thermosetting resin; the maximum temperature T2 is lower than the decomposition temperature of the thermosetting resin; and the pre-heating of the thermosetting resin is performed under the following conditions of temperature T0 and time t: 100null C.nullT0
