| Abstract:Styrene (SM), methyl methacrylate (MMA) and butyl acrylate (BA) were used tosynthesisepolyacrylic emulsion by core shell emulsion polymerization. Four kinds of emulsions were prepared by using various ratios of the monomers. Then, the emulsions and the rejects fibers were dispersed, coated, and dried together. Finally, fiber based water resistant materials were successfully fabricated. The Cobb values of the materials were tested respectively.The experiment results showed that under condition of m(Polyacrylic Emulsion)∶m(Rejects Fibers)=2∶1, the Cobb values of four materials prepared using from emulsions reached 5.0,9.8,19.2 and 7.1 g/m2respectively. The water resistant of the material prepared by using the emulsion which was synthesized on the basis of monomer mass ratio of 1∶1∶2 achieved the most stable property. The surface morphological structure of the materials was studied by using scanning electron microscope (SEM). |
