Preparation of Soap-free Styrene-acrylic Emulsion and Study on the Properties of Curing Film
摘要
Abstract
The soap-free styrene-acrylic emulsion was prepared by seed semi-continuous polymerization using re-active emulsifier instead of small molecule emulsifier,and styrene,methyl methacrylate,butyl acrylate,acrylic acid and 2-hydroethyl methacrylate as co-monomers. Then the styrene-acrylic emulsion was cured by curing agent and the curing film with good water resistance was obtained. The chemical structure of the styrene-acrylic copolymer and its curing film was characterized by Fourier transform infrared (FT-IR). The effects of reactive emulsifier content on the monomer conversion,coagulation rate,particle size,Zeta potential,latex stability of styrene-acrylic emulsion, as well as properties of curing film were investigated. The results showed that the reactive emulsifier took part in the copolymerization with other monomers, and the curing reaction occurred between curing agent and styrene-acrylic copolymer. With the increase of reactive emulsifier content,the monomer conversion and electric charge of the latex surface increased while the coagulation rate and particle size of latex decreased,resulting in the better stability of the latex. When the reactive emulsifier content was 3%,the styrene-acrylic curing film possessed good water resistance for the curing film could not exfoliated from the substrate or got white after immersed in water at 40℃ over 10 days.关键词
