丙烯酸酯热熔胶在聚酯织物基材上的润湿行为及其对粘合性能的影响
Wetting Behavior of Acrylate Hot-Melt Adhesive on Polyester Fabric Substrates and Its Influence on Adhesion Performance.
摘要(中文译文)
丙烯酸酯热熔胶（AHMAs）因其无溶剂特性和高粘接强度，被广泛应用于医用敷料、电子元件及汽车内饰等领域。然而，在不同涂布温度下其在多孔织物基材上的润湿行为——界面粘接的关键因素——仍缺乏深入理解。为探究涂布温度对丙烯酸酯热熔胶在织物基材上润湿与粘接性能的影响，本研究测量了胶粘剂（130–160 °C）的表观表面张力与粘度，以及基材（20–160 °C）的表观表面能。通过将这些测量结果与钢板上的接触角衰减曲线、冷脆断面的扫描电子显微镜观察及力学性能测试相结合，分析了温度对润湿铺展、渗透深度及粘接性能的影响。结果表明，随着温度升高，胶粘剂的表面张力和粘度降低，流动性提高；基材表面能无温度依赖性。对织物的渗透深度从16 μm增至25 μm，渗透均匀性逐渐改善。然而，剥离强度和环形初粘力均随温度升高而持续下降，最佳粘接温度为130 °C。基于Washburn方程的渗透深度模型可有效预测渗透行为。粘度对渗透效果的贡献超过50%，而润湿因素的贡献相对较小。本研究为优化丙烯酸酯热熔胶在织物基材上的涂布工艺提供了理论依据。
Abstract
Acrylate hot-melt adhesives (AHMAs) are widely used in medical dressings, electronic components, and automotive interiors due to their solvent-free nature and high bonding strength. However, their wetting behavior on porous fabric substrates under varying coating temperatures-a critical factor for interfacial adhesion-remains poorly understood. To investigate how coating temperature affects the wetting and adhesion of acrylic hot-melt adhesives on fabric substrates, the apparent surface tension and viscosity of the adhesive (130-160 °C) and the apparent surface energy of the substrate (20-160 °C) were measured. By combining these measurements with contact angle decay curves on steel plates, scanning electron microscopy of cold-brittle cross-sections, and mechanical property tests, the study analysed the effects of temperature on wetting and spreading, penetration depth, and adhesive performance. Results show that with increasing temperature, adhesive surface tension and viscosity decrease, while fluidity improves; substrate surface energy shows no temperature dependence. The penetration depth into the fabric increases from 16 μm to 25 μm, and penetration uniformity gradually improves. However, both peel strength and loop tack continuously decrease with rising temperature, with optimal adhesion at 130 °C. A penetration depth model based on the Washburn equation effectively predicts the penetration behavior. Viscosity accounts for more than 50% of the effect, whilst the wetting factor contributes to a lesser extent. This study provides a theoretical basis for optimizing the coating process of acrylic hot-melt adhesives on fabric substrates.
