摘要
探讨对中纤板进行薄木贴面装饰的技术可行性。并且 ,针对贴面过程中易产生的透胶、显底色、表面裂纹等问题 ,对工艺方法、胶粘剂的选配及各种工艺参数进行了研究。结果表明 :采用聚醋酸乙烯乳液胶和脲醛树脂胶以不小于1的比例混合施胶 ,并加以一定的面粉为填充剂 ,基材表面用钛白粉或隐蔽剂处理后 ,在上胶量为120g/m2 ,热压力1 0～1 5MPa ,温度120±5℃ ,时间120～80s的条件下压制出来的贴面装饰板的性能指标达到国标GB/T15104 -94优等品的要求。
The paper discusses the technical feasibility in veneer overlaying for medium density fiberboardIn the light of the defects emerging easily in the course of processing,such as penetrating glue,showing ground colour and surface slight crackle,the technique,adhesive and other process parameters are studiedThe results show that when the PVAC and UF are used together with the ratio not less than one,under the condition of the consumption of resin with filler is 120g/,hot press 10～15MPa,temperature is 120±5℃,time 60～80 seconds,the properties of the overlaid MDF can reach the requirement of high-class of overlaid board standard of China GB/T15104-94
