摘要

以EVA和APAO热熔胶为胶黏剂粘接木材单板和中密度纤维板（MDF）,探讨胶层温度对单板/MDF胶合强度的影响。结果表明:单板/MDF的胶合强度随胶层温度的升高显著降低;APAO胶合试样的耐温性能优于EVA胶;当EVA和APAO胶胶层温度分别低于41和47℃时,粘接的材料均有足够的胶合强度,可进行后续工序加工。为框架集成材在线异形拼接加工及封边自动化生产,提供重要依据。

Abstract

Veneer and medium density fiberboard（MDF） samples were glued together with EVA and APAO hot melt adhesives. The effect that adhesive layer temperature in the samples had on bonding strength was evaluated.The results showed that adhesive layer temperature had significant influence on bonding strength and the temperature resistant performance of the APAO was better than that of the EVA. When the adhesive layer temperature of the EVA and APAO was lowered under 41 ℃ and 47 ℃, respectively, the both samples could be strong enough for follow-up processing. This study result could be used in splicing processing of timber framework on-line manufacturing and wood edge banding automation applications.
