Anti-aging modified silane-terminated polyether resin, MS nail-free glue and preparation method thereof

The invention relates to anti-aging modified silane-terminated polyether resin, MS nail-free glue and a preparation method thereof, the anti-aging modified silane-terminated polyether resin is prepared from silane-terminated polyether resin and a reactive functional aid, and the mass of an amine antioxidant is 0.5-1.2% of the mass of the silane-terminated polyether resin; the silane-terminated polyether resin is prepared from acrylate-terminated polyether and vinyl silane under the catalysis of an olefin metathesis catalyst, wherein the molar ratio of the acrylate-terminated polyether to the vinyl silane is (1: 2)-(1: 3). The invention overcomes the defects of high cost, migration problem of auxiliaries, poor durability of colloid performance and the like in the existing preparation of anti-aging modified silane-terminated polyether resin and MS nail-free glue, and the silane-terminated polyether resin is directly synthesized by using acrylate-terminated polyether and vinyl silane under the catalysis of an ol
