内置电热实木复合地板基材冷压制备工艺研究

Cold-pressing Technology for Making Parquet Substrates with Built-in Electric Heating Elements

采用响应面法建立模型,分析冷压时间、冷压压力和施胶量工艺因素对内置发热实木复合地板基材胶合强度的影响。结果表明:冷压时间与施胶量对内置发热地板上下基材间的胶合强度显著影响,且冷压时间影响效果大于施胶量,冷压压力无显著影响。优化后的工艺参数为:冷压时间47 min、冷压压力1.2 MPa、施胶量215 g/m2,制备的地板基材的胶合强度为1.58 MPa。

Response surface methodology was used to establish a model which was used to analyze the influence of cold pressing time,pressure and adhesive spread on bonding strength of parquet substrates with built-in electric heating elements.The results showed that the cold pressing time and adhesive spread had significant effects on bonding strength between upper and lower layers of the substrates and that effect of the cold pressing time was greater than that of the adhesive spread.Cold pressing pressure had no significant effect.Under optimum manufacturing parameters like 47 min of cold pressing time,1.2 MPa of cold pressure and 215 g/m2 of adhesive spread,the bonding strength of the floor substrates reached 1.58 MPa.
