Abstract

Water glass (WG) has potential applications in many fields, but the poor water-resistance limits its further development. In the article, a kind of modified WG adhesive was designed from WG and poly (vinyl alcohol) (PVA), in order to improve the bonding properties between WG adhesive and poplar veneer. Preparation conditions of PVA-WG adhesive were optimized by response surface method. Based on the single factor experiments, the optimum values of the parameters were obtained by Box-Behnken design using the Design-Expert software. The results showed that the important parameters influencing the bonding strength were the mass ratio of PVA to WG, dosage of sodium tartaric acid (TA) and the aging time. The optimum technical conditions were the mass ration of PVA to WG 0.65, dosage of TA 1.00 g and the aging time 5.00 h. At this condition, bonding strength of as-prepared PVA-WG adhesive could reach 1.0407 MPa, close to the actual value of 1.01 MPa, so the model fits pretty well. The as-prepared PVA-WG adhesive had better adhesion properties to poplar veneer, which is meaningful for developing environmental friendly adhesive to replace organic adhesive in the wood-based panel field.
