Abstract
An aqueous acrylic emulsion was synthesized by the method of emulsion polymerization with methacrylate as a functional monomer, styrene as a hard monomer and n-butyl acrylate as a soft monomer. The methacrylic acid as the functional monomer achieved water-soluble and increased the adhesion. The effects of the monomer ratio, kind and amount of initiator agent, reaction temperature, stirring speed , monomer dropping time and the holding time on the emulsion and film properties were discussed. The experimental results show that the mass proportion of methacrylate, styrene and n-butyl acrylate is 5 : 17 : 20, the dropping time of the monomer mixture is from 2 to 3 h, the use amount of initiator ammonium persulfate is 0. 7% of the monomer mass, adding dropwise simultaneously with the monomer, OP-10 and sodium lauryl sulfate were selected as the emulsifier content with 2% and 1% of the monomer mass respectively, the reaction temperature is from 75 ℃ to 85 ℃ and the stirring speed is from 200 to 300 r/min, white emulsion with obviously blue light and good stability is obtained; under 100 ℃ , colourless and transparent film with good hardness, adhesion and flexibility is obtained.关键词
