| 摘要 | Provided is a method for producing a one-component moisture-curing polyurethane composition, the method comprising: a mixing step in which a liquid component (A) containing a polyol compound is mixed with a powder component (B) containing a filler so as to obtain a paste-like mixture of the liquid component (A) and the powder component (B); a dehydration step in which, following the mixing step, at least a portion of the residual moisture in the paste-like mixture is removed; a prepolymer generation step in which a polyisocyanate compound (C) is mixed with the paste-like mixture following the dehydration step so as to obtain a mixture containing a urethane prepolymer generated by a reaction between the polyisocyanate compound (C) and the polyol compound in the paste-like mixture; and a composition generation step in which the mixture is mixed with an aliphatic isocyanate compound (D) so as to obtain a one-component moisture-curing polyurethane composition. | ||

| 主权项 | 1. A method for producing a one-component moisture-curing polyurethane composition, the method comprising: a mixing step in which a liquid component (A) containing a polyol compound having two or more hydroxy groups in each molecule is mixed with a powder component (B) containing a filler so as to obtain a paste-like mixture of the liquid component (A) and the powder component (B); a dehydration step in which, following the mixing step, at least a portion of the residual moisture in the paste-like mixture is removed; a prepolymer generation step in which a polyisocyanate compound (C) having two or more isocyanate groups in each molecule is mixed with the paste-like mixture following the dehydration step so as to obtain a mixture containing a urethane prepolymer generated by a reaction between the polyisocyanate compound (C) and the polyol compound in the paste-like mixture; and a composition generation step in which the mixture is mixed with an aliphatic isocyanate compound (D) having at least two isocyanate groups in each molecule so as to obtain a one-component moisture-curing polyurethane composition. | ||
