Title:
CATALYST COMPOSITION FOR POLYURETHANE RESIN PRODUCTION AND METHOD FOR PRODUCING POLYURETHANE RESIN
Document Type and Number:
WIPO Patent Application WO/2008/018601
Kind Code:
A1
Abstract:
Disclosed is a catalyst composition for polyurethane resin production which
contains (A) triethylenediamine, (B) a specific polyisocyanurating catalyst
and/or (C) a specific highly temperature-sensitive catalyst. By using this
catalyst composition, a polyurethane resin can be molded with good curability,
while suppressing initial reactivity. Consequently, a polyurethane resin
having excellent moldability and fluidity can be produced with high productivity
by using the catalyst composition. The thus-obtained polyurethane resin is
suitably applicable to shoe soles. The component (B) is selected from the group
consisting of alkali metal salts of carboxylic acids, quaternary ammonium compounds
expressed as R1R2R3R4N+X-,
N,N,N'-trimethylaminoethylethanolamine, and 2,4,6- tris(dimethylaminomethyl)phenol,
while the component (C) is selected from the group consisting of triazole salts
and benzotriazole salts of 1,8-diazabicyclo[5.4.0]undecene-7 or 1,5-diazabicyclo[4.3.0]nonene-5.
The mixing ratio of the component (B) and/or the component (C) to the component
(A) is from 2% by weight to 60% by weight.
