| 目的 为了解决装饰纸贴面人造板的游离甲醛问题，探究无醛装饰纸贴面胶合板的优化工艺和贴面后涂饰水性聚氨酯的表面耐磨性能。方法 采用无醛豆胶为胶黏剂制备装饰纸贴面豆胶胶合板，并在其表面涂饰无醛水性聚氨酯涂料的方法。按照相关国标，检测和分析不同工艺参数对无醛装饰纸贴面豆胶胶合板的表面胶合强度以及不同水性聚氨酯涂料涂饰量对耐磨性能的影响。结果 在实验区间内，当无醛豆胶的单面施胶量为200 g/m2，热压温度为150 ℃，热压时间为1.5 min，热压压力为1 MPa时，无醛装饰纸贴面豆胶胶合板的表面胶合强度最高;当无醛水性聚氨酯涂料的表面涂饰量为190 g/m2时，无醛装饰纸贴面豆胶胶合板的表面耐磨性能最佳。结论 采用无醛豆胶为胶黏剂制备胶合板时，无醛豆胶具有较好的渗透性能，无醛水性聚氨酯涂料具有良好的表面性能。 |

| The work aims to solve the problem of free formaldehyde in decorative paper veneered wood-based panels and explore the process optimization of formaldehyde free decorative paper overlaying faced glue plywood and the surface wear-resisting property of applying waterborne polyurethane after facing. The decorative paper faced bean glue plywood was prepared by using formaldehyde free bean glue and formaldehyde free water-based polyurethane coating was applied to its surface. According to the relevant national standards, the effects of different process parameters on the surface bonding strength and wear resistance of formaldehyde free decorative paper faced bean plywood were tested and analyzed. In the test range, when the single-sided sizing amount of formaldehyde free bean glue was 200 g/m2, the hot pressing temperature was 150 ℃, the hot pressing time was 1.5 min, and the hot pressing pressure was 1 MPa, the surface bonding strength of formaldehyde free decorative paper faced bean glue plywood was the highest; when the surface finishing amount of aldehyde free waterborne polyurethane coating was 190 g/m2, the surface wear resistance of aldehyde free decorative paper faced bean glue plywood was the best. When formaldehyde free bean glue was used to prepare glue plywood, the formaldehyde free bean glue has good permeability and the formaldehyde free water based polyurethane coating has good surface property. |
