Composition of isocyanates, their use for the preparation of adhesives, and the thus produced aromatic adhesive joints

摘要

The invention relates to the use of an emulsifiable isocyanate composition in adhesives. The composition comprises an isocyanate composition, with a mass content of N=C=O functions of 10 % to 30 % and a viscosity of at most 1,500 mPa.s., a detergent agent, with a principal component of a compound or a mixture of compounds of general formula: [R20-(CH2-CH2-O)s-CH2-CH2-X')q-P(=O)m(O-)p-X-CH2-CH2(-O-CH2-CH2)n-O-R1, where p = between 1 and 2 (closed intervals, in other words inclusive limits), m =0 or 1, where p+m+q = max. 3, 1+p+2m+q = 5, X and X' = O or a simple bond, n and s independently = 5 to 25, R1 and R2 = independently or preferably the same aliphatic group not having an aromatic nucleus. The above is of application to the adhesive industry.
