Abstract
A styrene-acrylate emulsion was prepared using styrene(St),butyl acrylate(BA),methyl methacrylate(MMA) and acrylic acid(AA) as monomers,sodium dodecyl sulfate(SDS) and alkylphenol ethoxylates(OP-10) as blend emulsifier,potassium persulfate(KPS) as initiator.Experimental results showed that,when m(St)∶m(MMA)∶m(BA)∶m(AA)=9∶26∶61∶4,the dosage of blend emulsifier is 3% of the total mass of monomers,the dosage of initiator is 0.6% of the total mass of monomers,an emulsion with fine particle size and good stability can be obtained.The emulsion product was applied in the pulp for manufacture of corrugate paper,and the factors of styrene-acrylate emulsion that affect the performance of the paper product were discussed.
