The embodiment of the invention relates to the technical field of sealants, and discloses an environment-friendly MS adhesive which mainly comprises a high-activity silane-based prepolymer, a halogen-free flame retardant formed by silane modification and an environment-friendly non-toxic amino silane catalyst. Wherein silane modified aluminum hydroxide and silane modified ammonium polyphosphate are used as flame retardants and have better compatibility with prepolymers, so that the strength after curing is improved, the pollution to the environment is reduced, and a flame-retardant effect is also taken into account. In addition, the amino silane catalyst replaces a traditional organic tin catalyst, so that the environmental protection property of the MS adhesive is further improved. The invention further discloses a preparation method of the environment-friendly MS glue. The environment-friendly MS adhesive has the characteristics of rapid curing, low odor, low toxicity, high hardness, good toughness and wide
