| 目的 为了解决浸渍纸释放甲醛的问题， 对大豆蛋白胶用于强化地板装饰纸的压贴工艺进行探索， 找到合理的压贴工艺流程。 方法 在热压温度为 130 ℃， 热压压力为 2.5 MPa， 热压时间为 2 min，施胶量为 160 g/m2，对施胶后的装饰纸干燥至恒重以及控制板面涂水量为 75~80 g/m2的条件下，将装饰纸和高密度纤维板组坯、热压， 计算装饰纸表面水渍面积百分比， 并测定其表面胶合强度。 结果 表面胶合强度大于 1.0 MPa， 达到 GB/T 18102—2007 的技术要求， 解决了装饰纸表面的水渍问题。 结论 大豆蛋白胶可以用于压贴强化地板装饰纸， 确定其工艺流程为： 单板整理→施胶→干燥→板面涂水→组坯→热压→检测。 为表层纸以及平衡纸的压贴提供了参考。 |

| Objective To solve the problem of formaldehyde releasing from impregnated paper, the hot-pressing technology of decorative paper with soy protein-based adhesive for laminate flooring was investigated, to find out a reasonable technology workflow. Methods The hot-pressing temperature, hot-pressing pressure, hot-pressing time and adhesive dosage were controlled at 130 ℃, 2.5 MPa, 2 min and 160 g/m2, respectively. The decorative paper was then dried to a constant weight. The water used during spraying section was ranged between 75 and 80 g per square meter of the board surface. After lay-up and hot pressing of the decorative paper and high-density fibre plates, the percentage of water-stain area was calculated and the surface bond strength was determined. Results The results showed that the surface bond strength was larger than 1.0 MPa, which met the National Standard GB/T 18102—2007. Moreover, this process could solve the water-stain problem. Conclusion It was found that soy protein-based adhesive could be used to press decorative paper in hot-pressing technology. An improved process flow was found which included tidying the surface of the board, gluing up the decorative paper, drying the paper after gluing, spraying water on the surface of board, assembly, hot pressing and detection. This study provides reference for pressing of overlay paper and balance sheet paper. |
