【摘要】 目的 解决包装领域水基胶黏接性能受多物理特性影响，但缺乏定量分析与明确控制范围的问题。方法 以包装胶为例，将初黏性和剥离强度作为指标，综合采用Pearson相关性分析、主成分分析及随机森林算法，从单因素与多因素2个维度系统分析了粒度、接触角、开放时间、黏度等物理特性对黏接性能的影响，筛选出关键指标并明确其权重。在此基础上，采用3σ准则识别、剔除异常值，并结合置信区间确定各关键指标的推荐范围。结果 结果表明，接触角、黏度、开放时间与粒度为主控因子，推荐范围分别为接触角49°～78°、黏度371～590 mPa·s、开放时间10～24 s、粒度1.2～1.4μm。结论 本研究初步揭示了各关键物理特性对水基胶黏接性能的影响路径，且实验结果得出的合理区间可为产品质量控制与工艺优化提供量化依据。不仅为包装领域水基胶性能稳定性评估提供了科学理论支撑，更对推动水基胶在包装领域的高效应用具有实践参考价值。更多还原

【Abstract】 The work aims to address the issue that the bonding performance of water-based adhesives in the packaging field is affected by multiple physical properties but there is a lack of quantitative analysis and clear control ranges. With packaging adhesives as an example, initial tack and peel strength were taken as indexes, and Pearson correlation analysis, principal component analysis, and random forest algorithm were adopted comprehensively to systematically analyze the effects of physical properties such as particle size, contact angle, open time, and viscosity on their bonding performance from both single-factor and multi-factor dimensions, so as to screen out key indexes and clarify their weights. On this basis, the 3σ criterion was used to identify and remove outliers, and the confidence interval was used to determine the recommended range of each key index. The contact angle, viscosity, open time, and particle size were the main control factors, with the recommended ranges being contact angle 49°-78°, viscosity 371-590 mPa·s, open time 10-24 s, and particle size 1.2-1.4 μm. This study clarifies the effect mechanism of physical properties on adhesive bonding, and the reasonable intervals obtained from the experimental results can provide quantitative basis for product quality control and process optimization. It not only provides scientific theoretical support for the stability assessment of water-based adhesives, but also has practical reference value for promoting the efficient application of water-based adhesives in the packaging field.更多还原
