Abstract:
In this paper, white emulsion was modified by butyl acrylate, and the conditions for synthesizing a new wood adhesive-PVAc were determined. The performances, including viscosity, solid content, mechanical stability, and pH were tested. The performance for application, such as winter resistance,freeze thaw stability, and water resistance were tested and compared with that of the commonly used white emulsion. The results showed the new wood adhesive-PVAc had good performance and no pollution.[著者文摘]
Key words:
modified white emulsiom viscosity; solid content; winter resistance; water resistance
