Environment-friendly rough stone block coating glue and preparation method thereof

The invention provides an environment-friendly rough stone block coating adhesive and a preparation method thereof, the environment-friendly rough stone block coating adhesive comprises a component A and a component B. The component A comprises vinyl ester resin, a hardening agent and a wetting penetrant; the component B comprises an initiator; the vinyl ester resin is prepared from the following components in parts by weight: 17.5 to 27.5 parts of aliphatic long-chain epoxy vinyl ester resin, 25 to 35 parts of phenolic epoxy vinyl ester resin and 40 to 50 parts of environment-friendly reactive diluent; the environment-friendly reactive diluent is prepared from methacrylic acid-beta-hydroxyethyl ester and neopentyl glycol diacrylate. By selecting the specific vinyl ester resin, low viscosity and excellent water resistance, heat resistance and chemical corrosion resistance of the rough stone block coating glue are ensured, meanwhile, a glue film is endowed with relatively high mechanical strength, the storage
