摘要 为了解决人造板贴面中游离甲醛污染、透胶漏胶、工艺复杂等问题,选用固态的聚乙烯薄膜作为胶黏剂,对中密度纤维板进行薄木贴面装饰,并用正交试验对贴面板的制备工艺进行了优化。结果表明热压工艺因子和冷压时间对贴面板的表面胶合强度均有较大影响,当薄膜厚度为0.08 mm,热压压力为0.8 MPa,热压温度为140℃,热压时间为90 s,和2 min时,贴面板材的表面胶合强度达到0.9 MPa,满足国家标准GB/T 15104-2006《装饰单板贴面人造板》的要求。 In order to solve the problems of formaldehyde pollution,complex process,and leakage of gluein the veneer overlaid process of wood-based panels,the solid state polyethylene film was used as adhe-sive to decorate the medium density fiberboard. The preparation technology was optimized by orthogonaltest. Results showed that the surface bonding strength of the overlaid samples was significantly affectedby both hot pressing process factor and cold pressing time. When film thickness,hot press pressure,hotpressing temperature,hot pressing time and cold pressing time was 0.08 mm,0.8 MPa,140 ℃,90 s and 2 min,respectively,the comprehensive performance of the decorative panel reached 0.9 MPa,which metthe requirement of the National Standard GB/T 15104-2006"Decorative Veneered Wood-based Panels".
