ADHESION COMPOSITION FOR TIRE-CORD COMPRISING BLOCKED ISOCYANATE COMPOUND

摘要

An adhesion composition for tire-cord is provided to improve the property of a tire cord, to reduce the setting time and to prevent the precipitation of impurities. An adhesion composition for tire-cord comprises a blocked isocyanate compound indicated as the chemical formula 1. In the chemical formula 1, R1 is a C1~C6 alkylene group, C3~C12 cyclo alkylene substituted or non-substituted with C1~C4 alkyl group or C6~C12 arylene group substituted or non-substituted with C1~C4 alkyl group, wherein it is connected to 1,3-, 1,4-, 2,4-, 2,6- or 4,4- position of the cycloalkylene group as the same as the isocyanate radical (-N=C=O) or the other position; R2 is a C1-6 alkylene group or C5-6 cycloalkylene or cyclo phenylene structure, wherein single or at least two alkyl groups less than C4 are bonded to 2, 3, 4 or 5 position of cyclo structure; X is O or S; and Y has an aromatic ring structure constituting N, and comprises a molecular structure in introduced one X and one Y or 3 Y.
