改善塑料的硬度及耐刮能力
塑料的硬度及耐刮问题，改善塑料的硬度及耐刮能力主要有两种方式，其一是在塑料中加入硬质添加剂，常用的硬度添加剂为刚性无机填料及纤维（如芳纶纤维，玻璃纤维，碳纤维等）。PS:在塑料改性范畴刚性粒子的增加除了增加硬度，有时候也能起到增韧塑料的作用；
There are two ways to improve the hardness and scratch resistance of plastics. One is to add hard additives into plastics. The commonly used hardness additives are rigid inorganic fillers and fibers (such as aramid fiber, glass fiber, carbon fiber, etc.). PS: in the field of plastic modification, the increase of rigid particles can not only increase the hardness, but also sometimes toughen plastics;
其二是通过表面处理改进塑料的硬度。以PC（目前机身常见的塑料材料）为例，涂覆耐磨涂层是提升PC抗刮伤和耐磨性的最最最常用的方法。工业上，耐磨涂层主要技术路线集中在聚硅氧烷和多官能丙烯酸体系硬涂层。另外，聚氨酯韧性涂层也有少量应用，由于其粘接性强，可调整组分的硬度及软段，可改善涂层的物理性能，因此也可用作聚碳酸酯表面的耐磨涂层。
The second is to improve the hardness of plastics through surface treatment. Taking PC (the common plastic material of the fuselage) as an example, coating wear-resistant coating is the most commonly used method to improve the scratch resistance and wear resistance of PC. In industry, the main technical route of wear-resistant coating focuses on the hard coating of polysiloxane and multifunctional acrylic acid system. In addition, polyurethane tough coating also has a small number of applications. Due to its strong adhesion, the hardness and soft section of components can be adjusted to improve the physical properties of the coating. Therefore, it can also be used as a wear-resistant coating on the surface of polycarbonate.
