5) sequentially adding the interface treating agent, the leveling agent and the terminating agent into the rubber dispersion liquid, uniformly stirring, then adding the modified ethylene oxide-acrylic acid copolymer and the polyether modified dimethyl siloxane copolymer, and finally adding the pH regulator to finally obtain the required environment-friendly water-based rubber treating agent.
