Document Type and Number:
WIPO Patent Application WO/2016/159237
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive composition having exceptional friction stability. The adhesive composition of the present invention is a one-part-moisture-curing-type adhesive composition containing a urethane prepolymer (UP), a plurality of types of carbon black (CB), calcium carbonate, aliphatic isocyanate, a metal catalyst, and an amine catalyst. The DBP oil absorption of the first CB is 23-40 cm3/100 g, and the DBP oil absorption of the second CB is 85-120 cm3/100 g. The first CB content 1 is 25 parts by mass or higher, and the second CB content 2 is 9 parts by mass or higher, and the calcium carbonate content is 5-30 parts by mass, per 100 parts by mass of the UP. The calcium carbonate content is 5-50 parts by mass per 100 total parts by mass of content 1 and content 2.
