Title:
METHOD FOR PRODUCING ONE-COMPONENT MOISTURE-CURING POLYURETHANE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2014/097905
Kind Code:
A1
Abstract:
Provided is a method for producing a one-component moisture-curing polyurethane composition provided with: a mixing step in which a liquid component (A) containing a polyol compound is mixed with a powder component (B) containing a filler, providing 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 portion of the moisture remaining in the paste-like mixture is removed; a prepolymer generation step in which a polyisocyanate compound (C) is mixed with the dehydrated paste-like mixture, providing a mixture containing a urethane prepolymer generated according to a reaction between the polyisocyanate compound (C) and the polyol compound in the paste-like mixture; and a composition generation step in which the abovementioned mixture is mixed with a reaction product (D) of an aliphatic isocyanate (d1) and an alkoxysilane (d2), providing the one-component moisture-curing polyurethane composition.
