Provided is a reactive anti-microbial and anti-contamination isocyanate trimethylglycine compound according to formula (I) or (II), and a preparation method therefor. R 1 represents OCN-L-NHCOO-R' or represents OCN-L-NHCONH-R'; L is a residual base remaining from the reaction of a di-isocyanate compound with a hydroxy or amino; R' = -(CH 2) m, wherein m is any integer between 1 and 6; or, R' = -(CH 2) nO(CH 2) y, wherein n is any integer between 1 and 6, and y is any integer between 1 and 6; or, R' = -(CH 2) mAr, wherein m is any integer between 1 and 6; or, R' = -(CH 2) nO(CH 2) yAr, wherein n is any integer between 1 and 6, y is any integer between 1 and 6, and Ar is an aryl; R 2 represents -(CH 2) pCH 3, wherein p is any integer between 1 and 17; R 3 represents -(CH 2) pCH 3, wherein p is any integer between 1 and 17; R 4 represents -(CH 2) q, wherein q is any integer between 1 and 17; R 5 represents a substituent on the pyridine ring; A represents -COO or -SO 3. |
