摘　　要：三聚氰胺浸渍橡木薄单板贴面实木复合地板是参考三聚氰胺浸渍纸贴面生产工艺生产出的表面凹凸实木复合地板。使用三聚氰胺胶黏剂、固化剂、渗透剂、脱膜剂(配比为500:1:1:1)混合液浸渍橡木薄单板,然后在真空度为0.08 MPa时保压浸渍5 min,在大气条件下放置30 min,取出后再放入90℃鼓风干燥箱中干燥10 min。浸渍完成的橡木薄单板与基材经热压成型为表面凹凸的实木复合地板。考虑热压温度、热压压力、热压时间对其凹凸表面成型的影响,每个因素取4个水平,制定因素水平表,选择正交表进行试验。对试验结果进行浸渍剥离及表面纹理深度的测量分析,得到最优的热压工艺条件为温度150℃、压力1.2 MPa、时间70 s。三聚氰胺浸渍的橡木贴面复合地板表面纹理、色泽、手感都更加接近自然。Reference the producing technology of laminate floor,the hot-pressing of engineered floor which has bumpy surface overlaying with melamine formaldehyde resin（MF）impregnated oak veneer was studied. The oak veneer is dipped in the mixed liquor which has melamine formaldehyde resin,curing agent,penetrating agent,release agent（ratio of 500：1：1：1）.After dipping 5 min when the vacuum degree is 0.08 MPa,it keeps 30 min in room conditions. Then dry 10 min in drying oven with temperature is 90 ℃.The impregnated oak veneer and ply wood as based of engineered flooring are put into the hot press under the different temperature,pressure and time to process shaping of its bumpy surface. The four levels of each factor of hot- press is selected to investigate the effect on shaping of its bumpy surface in the experiment.
