Document Type and Number:
Japanese Patent JP2017119737
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a synthetic resin emulsion capable of obtaining a cured coating film which is excellent in water resistance, is excellent balance between a strength and elongation, and prevents elution of a surface active agent.SOLUTION: In a method for producing a synthetic resin emulsion obtained by subjecting a monomer component [I] to multistage emulsion polymerization, a reactive surface active agent containing an anionic type reactive surface active agent and a nonionic type reactive surface active agent is used as an emulsifier, an amount of the reactive surface active agent to be used is 4 pts.wt. or less with respect to 100 pts.wt. of the monomer component [I], a content ratio (weight ratio) of the anionic type reactive surface active agent and the nonionic type reactive surface active agent is 55/45 to 90/10, and an amount of the nonionic type reactive surface active agent to be used in polymerization of the last stage is 60 wt.% or more with respect to the whole nonionic type reactive surface active agent.SELECTED DRAWING: None
