    摘要:

    车用聚丙烯(PP)在使用中易受到刮伤从而影响产品美观及使用性能。研究PP耐刮擦性能的影响因素,改善PP耐刮擦性能是满足车用耐刮擦PP市场需求的重要前提。以PP为基材,探究了4种不同作用机理的耐刮擦剂(芥酸酰胺、硅酮母粒、滑石粉和聚硅氧烷)对PP力学性能、热性能、结晶性能和耐刮擦性能的影响,并利用偏光显微镜和超景深三维显微镜观察PP材料刮擦表面的形貌。结果表明:4种耐刮擦剂使部分PP材料的冲击强度或弯曲强度显著提高,但拉伸强度均小幅度降低;芥酸酰胺、硅酮母粒和聚硅氧烷不改变PP的结晶形貌和结晶行为,滑石粉则破坏PP的结晶性能;4种耐刮擦剂均降低PP的摩擦系数和色差值(ΔL),改善其耐刮擦性能,其中聚硅氧烷不仅能改善PP的耐刮擦性能,其ΔL下降约89%,并能有效抑制PP的析出发黏和发白现象。

    Abstract:

    Automotive polypropylene (PP) is susceptible to scratches, which cause appearance and performance loss during use. Studying the factors affecting PP scratch resistance and improving PP scratch resistance are important prerequisite for the market demand of scratch-resistant PP for vehicles. Using PP as substrate, the effects of four kinds of scratch-resistant agents with different action mechanisms (erucamide, silicone masterbatch, talc powder and polysiloxane) on mechanical properties, crystallization properties and scratch resistance of PP were investigated. The morphology of the scraped surface of the material was observed by polarizing microscope and ultra-depth-of-field three-dimensional microscope. The results showed that four kinds of scratch-resistant agents significantly improved the impact strength or bending strength of some PP materials, but the tensile strength decreased slightly. Erucamide, silicone masterbatch and polysiloxane did not change the crystallization morphology and crystallization behavior of PP, while talc destroyed the crystallization properties of PP. Four kinds of scratch-resistant agents all reduced the friction coefficient and color difference of PP (ΔL) and improved its scratch resistance, among which polysiloxane could not only improve the scratch resistance of PP, reduce its ΔL by about 89%, but effectively inhibit the precipitation, stickiness and whitening of PP.
