Preparation of Functional Acrylic Resin Emulsion and Its Waterproofing Properties on Paper Surface
An acrylic resin emulsion waterproofing agent was prepared from emulsifier 1831,emulsifier AEO-9,isooctyl acrylate,styrene,glycidyl acrylate and initiator V50.The effect of total amount of emulsifier,the ratio of emulsifier 1831 to AEO-9 on the particle size distribution,water resistance and morphology of acrylic resin emulsion were investigated,and the acrylic resin emulsion was characterized by particle size analyzer,contact angle tester,scanning electron microscope and infrared spectrum.At the same time,the mechanical stability,dilution stability and calcium ion stability of acrylic resin emulsion were studied.The results showed that when the total emulsifier accounted for 1.35%of the total monomer,and the ratio of emulsifier 1831 and AEO-9 was 2∶1,the acrylic resin emulsion had better stability,smaller particle size and distribution.The maximum contact angle on paper was obtained after waterproof treatment at 120℃for 5 min,and the results showed good mechanical stability,dilution stability and calcium ion resistance.
