摘要:
为优化防腐马尾松木材的胶合工艺,解决马尾松人工林木材在木结构领域应用的关键问题,选用水性高分子异氰酸酯(EPI)和单组分聚氨酯(PU)两种木结构常用胶黏剂,制备两层拉伸剪切胶合试样并检测其剪切强度和木破率,采用正交试验分析预处理方法、单位压力、涂胶量、加压时间等因子对防腐马尾松木材胶合性能的影响,优选胶合工艺参数。结果表明,在试验所选取因子水平范围内,EPI胶合性能的主要显著影响因子是单位压力,较优的工艺条件为预处理方法采用防腐-压刨,单位压力1.3 MPa,涂胶量200 g·m-2,加压时间2 h;PU胶合性能的主要显著影响因子是预处理方法,较优的工艺条件为预处理方法采用压刨-防腐,单位压力0.8 MPa,涂胶量100 g·m-2,加压时间1.5 h。由于两种胶黏剂的性质不同,工艺因子对其胶合性能的影响表现出明显差异。
Abstract:
In order to optimize the bonding technology of preservative-treated Pinus massoniana wood, and promote the use of P. massoniana plantation wood in the construction of timber structures, emulsion polymer isocyanate(EPI) and one-component polyurethane(PU) were evaluated as representative adhesives. Two-layers bonding joints were prepared to evaluate their shear strength and wood failure ratio under tensile loading. The effects of the pretreatment method, unit pressure, glue spread, and pressing time, on the bonding performance of preservative-treated P. massoniana wood were analyzed using orthogonal tests, and optimal parameters were determined. The results indicated that within the factor levels evaluated in the experiment, pressure was the main significant factor affecting EPI bonding performance, while the pretreatment method was that for PU bonding performance. The preferred parameters for EPI were: the pretreatment method of preservative treatment-pressure slicing, a unit pressure of 1.3 MPa, glue spread of 200 g·m-2, and a pressing time of 2 h. The preferred parameters for PU were: the pretreatment method of pressure slicing-preservative treatment, a unit pressure of 0.8 MPa, glue spread of 100 g·m-2, and a pressing time of 1.5 h. Owing to the property differences between the two adhesives, the effects of the factors on their bonding performance showed clear differences.
