Styrene-acrylic emulsion and preparation method thereof

The invention belongs to the technical field of coating emulsion preparation, and particularly relates to a styrene-acrylic emulsion and a preparation method thereof.The styrene-acrylic emulsion is prepared in one step through glow discharge plasma electrolysis initiation, and the method has the advantages of being simple in process, convenient to operate, controllable in reaction (the reaction progress can be controlled by changing parameters such as discharge voltage and power-on time) and the like; the method has the advantages of mild preparation conditions (without N2 protection), no need of addition of an initiator, avoidance of secondary pollution caused by the initiator, no need of an organic solvent, safety, reliability, few product impurities, high purity, uniform particle size and good dispersity, and is an environment-friendly new green preparation technology; the emulsion prepared by the invention has high thermal stability and uniform particle size, and can be used in the industries of adhesives
