| Abstract: | Casein grafting acrylate sizing agent was synthesized by soap-free emulsion polymerization using casein(CA),diacetone acylamide(DAAM),methyl methacrylate(MMA),butyl acrylate(BA) and acrylonitrile(AN) as major monomers.The effects of dosage of casein on emulsion stability and paper sizing degree,the ratio of soft and hard monomers and the addition of crosslinking monomer DAAM on paper sizing degree and physical strength were investigated.The results indicate that when CA accounts for 30% of monomers,the mass ratio of soft and hard monomers is 1.3 and w(DAAM)=2%,the sizing agent has good paper water resistance and strengthening function,glue consumption,the sizing degree and the folding endurance is 1.15 g/m2,30.2 s and 4672 respectively. |
