交联剂与稀释剂在高性能聚合物涂层中的相互作用机理及其对涂膜物性的影响研究

Mechanism of crosslinker and diluent in high performance polymer coating and its influence on coating properties

摘要

本文聚焦高效能聚合物涂料中交联剂和稀释剂的相互作用原理，并分析它们如何影响涂层的物理特性。在物理层面上，稀释剂会作用于交联剂的溶解与分布状况以及整个系统的粘度大小；从化学角度来看，它对交联过程的速率有着推进或阻碍的效果，并且有可能引发一些附加的化学反应。这两个因素显著地决定了涂层的硬度、弹性、粘附度、耐磨损能力、抗腐蚀性质以及抵御自然侵蚀的能力。另外，以汽车涂料为例，揭示了选材对于涂层功能的现实影响，为提升涂层性能质量提供了参考。

Abstract

This paper focuses on the interaction principle of crosslinking agents and diluents in high-efficiency polymer coatings, and analyzes how they affect the physical properties of the coatings. On the physical surface, the diluent acts on the dissolution and distribution of the crosslinker and the viscosity of the whole system; chemically, it advances or hinders the rate of the crosslinking process and may cause some additional chemical reactions. These two factors significantly determine the coating hardness, elasticity, adhesion, wear resistance, corrosion resistance properties, and the ability to resist natural erosion. In addition, taking automotive coating as an example, it reveals the realistic influence of material selection on coating function, and provides reference for improving the performance quality of coating.
