| Abstract: | The semi-continuous emulsion polymerization was adopted to prepare vinyl acetate-acrylate emulsion adhesive for wood industry. The results showed that the properties of the vinyl acetate-acrylate emulsion adhesive were greatly influenced by the selection of copolymerized monomers, polymerizing time, polymerizing temperature, agitating rate, the dosage of emulsifier and initiator. The better vinyl acetate-acrylate emulsion adhesive could be prepared with features of good stability, water resistance and high bonding strength by selecting acrylic acid series monomer for the copolymerization, 4 -5 h for polymerization duration under 80 ℃, 180 -240 r/min as agitating rate and 3.0% and 0. 5% of emulsifier and initiator respectively. |
