Synthesis and characteristics of pvac resin with plasticizer for wood products

Abstract: 

The Adhesives industry is one  of  the most importance of  PVAc Resin, especially wood product manufacturer .it has many advantages low cost, easy in appilication, minimal harmful in environment effects. However, The PVAc resin also having the disadvantages that it’s bonding  and  viscosity was dependent the work condition get worse at the low temperature.  For that phthalate-based plasticizer is used to complement these disadvantages, Bond strength and heat-resistance is weakened by without adding the plasticizer and in the low temperature. The plasticizer quantity should be increased. The properties rising viscosity, curing time reduced and the storage stability, water resistant was increased In addition to these the phthalate-based plasticizer to the PVAc resin. In this study has  eliminated the disadvantages of PVAc resin emulsion  and also adhesive  use where the bond strength more and less for timber so that  economy for carpenters. The  synthesized PVAc resin for timber adhesion that is excellent in woodwork, thermal resistance,  minimum film forming temperature, bond strength performance and storage stability
